Safety Precautions and Working Techniques
Because a chain saw is a high-speed, fast-cutting power tool, special safety precautions must be observed to reduce the risk of personal injury.
It is important that you read, fully understand and observe the following safety precautions and warnings. Read the instruction manual and the safety instructions periodically. Careless or improper use may cause serious or fatal injury. Save the instruction man­ual for future reference.
WARNING
The use of this chain saw may be hazardous. The saw chain has many sharp cutters. If the cutters contact your flesh, they will cut you, even if the chain is not moving.
WARNING
Reactive forces, including kickback, can be dangerous. Pay special attention to the section on reactive forces.
Have your STIHL dealer show you how to operate your chain saw. All safety precautions that are generally observed when working with an axe or a hand saw also apply to the operation of chain saws. Observe all applicable federal, state and local safety regulations, standards and ordinances.
WARNING
Do not lend or rent your chain saw without the instruction manual. Be sure that anyone using it understands the information contained in this manual.
The use of noise emitting chain saws may be restricted to certain times by national, state or local regulations.
Use your chain saw only for cutting wooden objects.
WARNING
Working with an electric chain saw in the woods – i.e. felling or limbing – is very dangerous. Electric chain saws are intended for stationary use in yards, buildings, etc.
WARNING
Do not use it for other purposes, since misuse may result in personal injury or property damage, including damage to the chain saw.
WARNING
Minors should never be allowed to use this chain saw. Bystanders, especially children, and animals should not be allowed in the area where it is in use.
Most of these safety precautions and warnings apply to the use of all STIHL chain saws. Different models may have different parts and controls. See the appropriate section of your instruction manual for a description of the controls and the function of the parts of your model.
WARNING
Always switch off the motor, move front hand guard to ƒ and remove the battery before transporting, storing or carrying out any work on the chain saw. This avoids the risk of the motor starting unintentionally.
STIHL recommends the use of genuine STIHL replacement parts. They are specifically designed to match your model and meet your performance requirements.
Safe use of a chain saw involves 1 the operator 2 the chain saw 3 the use of the chain saw.
THE OPERATOR
Physical Condition You must be in good physical condition
and mental health and not under the influence of any substance (drugs, alcohol, etc.) which might impair vision, dexterity or judgment. Do not operate this chain saw when you are fatigued.
WARNING
Be alert – if you get tired, take a break. Tiredness may result in loss of control. Working with any power tool can be strenuous. If you have any condition that might be aggravated by strenuous work, check with your doctor before operating this chain saw.

WARNING
Prolonged use of a chain saw (or other power tools) exposing the operator to vibrations may produce whitefinger disease (Raynaud's phenomenon) or carpal tunnel syndrome.
These conditions reduce the hand's ability to feel and regulate temperature, produce numbness and burning sensations and may cause nerve and circulation damage and tissue necrosis.
All factors which contribute to white­finger disease are not known, but cold weather, smoking and diseases or physical conditions that affect blood vessels and blood transport, as well as high vibration levels and long periods of exposure to vibration are mentioned as factors in the development of whitefinger disease. In order to reduce the risk of whitefinger disease and carpal tunnel syndrome, please note the following:
Wear gloves and keep your hands
warm.
Keep the chain saw well
maintained. A chain saw with loose components will tend to have higher vibration levels.
Keep the saw chain sharp and the
saw well maintained. A dull saw chain will increase cutting time, and pressing a dull saw chain through wood will increase the vibrations transmitted to your hands.
Maintain a firm grip at all times, but
do not squeeze the handles with constant, excessive pressure. Take frequent breaks.
All the above-mentioned precautions do not guarantee that you will not sustain whitefinger disease or carpal tunnel syndrome. Therefore, continual and regular users should closely monitor the condition of their hands and fingers. If any of the above symptoms appear, seek medical advice immediately.
WARNING
According to STIHL’s current knowledge, the electric motor of this chain saw should not interfere with a pacemaker. When in doubt, however, persons with a pacemaker should consult their physician and the pacemaker manufacturer before operating this chain saw.
Proper Clothing
WARNING
To reduce the risk of injury, the operator should wear proper protective apparel.
Clothing must be sturdy and snug-fitting, but allow complete freedom of movement.To reduce the risk of cut injuries, wear the type of overalls, long pants or chaps that con­tain pads of cut-retardant material. Avoid loose-fit­ting jackets, scarfs, neckties, jewelry, flared or cuffed pants, uncon­fined long hair or anything that could become caught on branches, brush or the moving parts of the chain saw. Secure hair so it is above shoulder level..
Good footing is very important. Wear sturdy boots with nonslip soles. Steel-toed safety boots are recommended. Never wear sandals, flip-flops or go barefoot.
Always wear heavy-duty work gloves (e.g. made of leather or wear resistant material) when handling the chain saw and the cutting tool. Heavy-duty, nonslip gloves improve your grip and help to pro­tect your hands.

To reduce the risk of injury to your eyes never operate your power tool unless wearing goggles or properly fitted protec­tive glasses with adequate top and side protection complying with ANSI Z87 "+" (or your applicable national stand­ard). If there is a risk of injury to your face, STIHL recommends that you also wear a face shield or face screen over your goggles or protective glasses.
Wear an approved safety hard hat to reduce the risk of injury to your head when there is a danger of head injuries.
Chain saw noise may damage your hearing. Such damage can result from a combination of noise level and length of usage. Although this battery powered product is relatively quiet, STIHL recommends that operators wear sound barriers (ear plugs or ear mufflers) if using the saw for more than 2.5 hours during the course of a day. Continual and regular users should have their hearing checked regularly.
Be particularly alert and cautious when wearing hearing protection because your ability to hear warnings (shouts, alarms, etc.) is restricted.
THE CHAIN SAW
For illustrations and definitions of the chain saw parts see the chapter on "Main Parts."
WARNING
Never modify this chain saw in any way. Only attachments supplied by STIHL or expressly approved by STIHL for use with the specific STIHL model are authorized. Although certain unauthorized attachments are useable with STIHL chain saws, their use may, in fact, be extremely dangerous.
WARNING
Never operate your chain saw if it is damaged, improperly adjusted or maintained, or not completely or securely assembled.
If this chain saw is subjected to unusually high loads for which it was not designed (e.g. heavy impact or a fall), always check that it is in good condition before continuing work. Check in particular that the controls and safety devices are working properly. Do not continue operating this machine if it is damaged. In case of doubt, have it checked by your STIHL servicing dealer.
THE USE OF THE CHAIN SAW
Transporting the Chain Saw
WARNING
Always switch off the motor and engage the chain brake by moving the front hand guard to ƒ before putting the chain saw
down. This avoids the risk of the motor starting unintentionally. Carrying a chain saw with the motor running may be extremely dangerous.
Accidental acceleration of the motor can cause the saw chain to rotate. Always engage the chain brake by moving the front hand guard to ƒ when taking more than a few steps.
By hand: When transporting your chain saw by hand, the motor must be switched off with the chain brake engaged and the chain saw must be in the proper position, i.e., grip the top handle; the chain guard (scabbard) should be over the chain and guide bar, which should point backwards, away from the direction in which you are walking.
By vehicle: When transporting in a vehicle, keep saw chain and bar covered with the chain guard (scabbard).
MSA 160 C, MSA 200 C

English
Properly secure your chain saw to prevent turnover and damage to the chain saw.
Before Operation Take off the chain guard (scabbard) and
inspect the chain saw for proper condition and operation. (See the maintenance chart near the end of the instruction manual.)
WARNING
Always check your chain saw for proper condition and operation before starting, particularly the trigger switch, trigger switch lockout, front handle guard and cutting attachment. The trigger switch and the trigger switch lockout must move freely and always spring back to the stop position. Ensure that the trigger switch will not engage when the trigger switch lockout is not pressed. Never attempt to modify the controls or safety devices.
To reduce the risk of injury, never use a saw if any part is damaged or does not function properly. Take the saw to your local STIHL servicing dealer. Do not use the saw until the problem has been rectified.
For proper assembly of the bar and chain follow the procedure described in the chapter "Mounting the Bar and Chain" of your instruction manual. STIHL Oilomatic saw chain, guide bar and sprocket must match each other in gauge and pitch. Before replacing any bar and chain, see the chapter entitled "Specifications" in the instruction manual and the chapter "Reactive Forces including Kickback."
Since longer bars add weight and may be more difficult to control, select the shortest bar that will meet your cutting needs.
WARNING
Proper tension of the saw chain is extremely important. In order to avoid improper setting, the tensioning procedure must be followed as described in your manual. Always make sure the hexagonal nut(s) for the sprocket cover is (are) tightened securely after tensioning the saw chain in order to secure the bar. Never start the chain saw with the sprocket cover loose. Check saw chain tension once more after having tightened the nut(s) and thereafter at regular intervals (whenever the saw is shut off). If the saw chain becomes loose while cutting, switch off the motor and engage the chain brake by moving the front hand guard to ƒ, remove the battery from the chain saw and then tighten. Never try to adjust the saw chain while the motor is running!
WARNING
After adjusting a saw chain, let the motor run for a while, then switch motor off and engage the chain brake by moving the front hand guard to ƒ. Remove the battery from the chain saw and recheck saw chain tension. Proper saw chain tension is very important at all times.
Keep the handles clean and dry at all times; it is particularly important to keep them free of moisture, pitch, oil, grease or resin in order for you to maintain a firm grip and properly control your chain saw.
Check contacts in battery compartment for foreign matter. Keep clean.
Fit the battery correctly – it must engage audibly.
WARNING
Before disengaging the chain brake and switching on your chain saw, be sure that the guide bar and saw chain are clear of you and all other obstructions and objects, including the ground. If the upper quadrant of the tip of the bar touches any object, it may cause kickback to occur (see section on reactive forces). Never attempt to start the chain saw when the guide bar is in a cut or kerf.
For specific starting instructions, see the chapter "Switching On" of your instruction manual.
Battery
WARNING
Risk of fire, explosion and/or burns, including chemical burns. Do not disassemble, crush, heat above 212 °F (100 °C), expose to fire or inciner­ate. Never expose the battery to microwaves or high pressures.
Do not place the battery on or near fires, stoves or in other high-temperature locations. Do not place the battery in direct sunlight or store it inside a vehicle in hot weather. Doing so may cause the battery to generate heat, rupture or
6
MSA 160 C, MSA 200 C
English
ignite. Using the batteries in this manner may also result in a loss of performance and a shortened battery life.
In case of fire: stay clear of any vapors or gases generated, taking wind direction into account. If possible without danger, remove battery from the vicinity of the fire. In principle, cooling the battery or extinguishing the fire with water is possible. It is preferable to extinguish the fire with a multipurpose dry chemical fire extinguisher. As for any fire, evacuate the area and fight the fire from a safe distance. Once the fire has been extinguished, the area should be monitored (fire watch) in case of a flare­up, until the battery has cooled sufficiently. Restrict access to the area until completion of clean-up. Do not touch the burnt battery or any spilled liquids. Use inert absorbent to absorb spilled liquids.
Use and store the bat­tery only within a temperature range from 14 °F (-10 °C) up to no more than 122 °F (+ 50 °C). Protect the bat­tery from direct sunlight.
WARNING
Use STIHL batteries only with STIHL power tools, and charge them only with STIHL chargers. Replace battery with STIHL battery only. Use only genuine STIHL rechargeable batteries.
Charge the battery before use.
Do not immerse the bat­tery in fluids.
WARNING
Do not open, drop, hit or damage battery. Never insert objects into the battery's cooling slots, since they may damage the battery. The battery contains safety features and devices which, if damaged, may cause the battery to generate heat, rupture or ignite. Never use or charge a defective, damaged, cracked or deformed battery.
Immediately discontinue use of the battery if, while using, charging or storing, it emits an unusual smell, feels hot or appears abnormal in any other way.
WARNING
Fluid may leak from the battery if it is damaged or is not used properly – avoid contact with the skin! Leaking battery fluid can cause skin irritation and chemical burns. In the event of accidental contact, immediately rinse thoroughly with mild soap and water. If fluid gets into your eye(s), do not rub your eye(s) but rinse water over the open eye(s) for 15 minutes at least. Also seek medical attention immediately.
WARNING
Never bridge (short circuit) the battery terminals with metallic objects, since this may damage the battery and possibly cause a fire. Keep a battery that is not in
use away from metal objects (e.g. nails, coins, jewelry). Do not use metal containers for transporting batteries.
Store the battery out of reach of children in a cool and dry area away from direct sunlight and excess heat or cold (14 °F – 122°F (-10°C – +50°C)).
Charger Use only original STIHL chargers. Use only for charging geometrically
matching STIHL batteries with a maximum capacity of 50 Ah and a maximum voltage of 42 V.
Never charge defective, leaking or deformed batteries.
Connect the charger only to a power supply with the voltage and frequency specified on the rating plate. Always plug the charger into a properly installed wall outlet. Do not use an extension cord unless absolutely neccessary (see below).
Never use a charger with damaged housing, damaged power supply cord or damaged plug. Do not operate the charger if it has received a sharp blow, been dropped or otherwise damaged in any way.
Do not open or dissassemble charger – there are no user serviceable parts inside.
Store charger out of the reach of children.
Protect the charger from rain and dampness. Keep charger dry.
MSA 160 C, MSA 200 C

English
3999BA000 KN
Use and store charger only indoors in dry rooms.
Operate charger at temperatures between 41 °F (5 °C) and 104 °F (40 °C).
Allow the charger to cool down normally – do not cover it.
Never bridge the contacts of the charger with metallic objects (e.g. nails, coins, jewelry) – short circuit. The charger will be damaged by a short circuit.
In the event of smoke or fire in the charger, disconnect it from outlet immediately.
WARNING
To reduce the risk of electric shock or short circuit, do not insert any objects into the charger's cooling slots.
WARNING
The charger heats up during the charging process. Do not operate on an easily combustible surface (e.g. paper, cardboard, textiles) or in an easily combustible environment – risk of fire.
WARNING
Do not operate in a hazardous location, i.e. in a location where there are combustible liquids (fumes), vapors or dusts. Chargers can produce sparks, which may ignite the dust or vapors – risk of explosion.
Check the charger's power supply cord and plug regularly for dam­age. If the power supply cord or plug is damaged, immediately disconnect the plug from the wall outlet to avoid the risk of electric shock.
Never jerk the power supply cord to disconnect it from the wall outlet. To unplug, grasp the plug, not the cord. Have a damaged power supply cord repaired by an experienced electrician.
Do not use the power supply cord for any other purpose, e.g. for carrying or hanging up the charger.
Never use power supply cords that do not comply with regulations.
Make sure the power supply cord is located and/or marked so that it will not be stepped on, tripped over, come in contact with sharp edges or moving parts or otherwise be subjected to damage or stress.
An extension cord should not be used unless absolutely necessary. If an extension cord must be used, plug the charger into a properly wired 16 gauge (AWG 16) or heavier gauge extension cord with blades that are the same number, size and shapes as the blades on the charger.
To reduce the risk of electric shock: – Always connect the unit to a
properly installed wall outlet.
Make sure the insulation of the
power supply cord and plug is in good condition.
Unplug the power supply cord from the outlet when charger is not in use.
Never store a battery in the charger. Holding and Controlling the Chain Saw Always hold the chain saw firmly with
both hands when you are working. Place your left hand on the front handle bar and your right hand on the rear handle.
Left-handers should follow these instructions too. Wrap your fingers tightly around the handles, keeping the handles cradled between your thumb and forefinger. With your hands in this position, you can best oppose and absorb the push, pull and kickback forces of your saw without losing control (see section on reactive forces).
WARNING
To reduce the risk of seri­ous or fatal injury to the operator or bystanders from loss of control, never use the chain saw with one hand. It is more difficult for you to control reactive forces and to prevent the bar and chain from skating or bouncing along the limb or log.

001BA082 KN
WARNING
To reduce the risk of cut injuries, keep hands and feet away from the cutting tool. Never touch a moving cutting tool with your hand or any other part of your body.
WARNING
Keep proper footing and balance at all times. Special care must be taken in slippery conditions (wet ground, snow) and in difficult, overgrown terrain. Be extremely cautious when working on slopes or uneven ground. Watch for hidden obstacles such as tree stumps, roots, rocks, holes and ditches to avoid stumbling. There is increased danger of slipping on freshly debarked logs. For better footing, clear away fallen branches, scrub and cuttings. Use extreme caution when cutting small-size brush, branches and saplings because slender material may catch the saw chain and be whipped toward you or pull you off balance.
WARNING
Take extreme care in wet and freezing weather (rain, snow, ice). Put off the work when the weather is windy, stormy or rainfall is heavy.
WARNING
To reduce the risk of injury from loss of control, never work on a ladder or any other insecure support. Never hold the machine above shoulder height. Do not overreach.
Never put pressure on the chain saw when reaching the end of a cut. The pressure may cause the bar and rotating saw chain to pop out of the cut or kerf, go out of control and strike the operator or some other object. If the rotating saw chain strikes some other object, a reactive force may cause the moving saw chain to strike the operator.
STIHL recommends that first-time users should cut logs on a sawhorse – see "Cutting small logs."
Working Conditions Operate your chain saw only under good
visibility and daylight conditions. Work carefully.
Do not use your chain saw in explosive atmospheres, such as in the presence of flammable liquids, gases or dust.
WARNING
Your chain saw is a one-person machine. Do not allow other persons in the general work area. Switch off the motor immediately if you are approached.
WARNING
Even though bystanders should be kept away from the running chain saw, never work alone. Keep within calling distance of others in case help is needed.
MSA 160 C, MSA 200 C
Position the chain saw in such a way that your body is clear of the cutting attachment whenever the motor is running. Stand to the left of cut while bucking.
WARNING
To reduce the risk of injury to bystanders and damage to property, never let your chain saw run unattended. When it is not in use (e. g. during a work break), switch it off and make sure that unauthorized persons do not use it. To do this, engage
9
English
the chain brake by moving the front hand guard to ƒ and remove the battery from the chain saw.
WARNING
Operate your chain saw so that it produces a minimum of noise – do not run motor unnecessarily and accelerate the motor only for cutting.
WARNING
Use of this chain saw (including sharpening the saw chain) can generate dust, oil mist and fumes containing chemicals that are known to cause respiratory problems, cancer, birth defects, or other reproductive harm. If you are unfamiliar with the risks associated with the particular dust, mist or fume at issue, consult your employer, governmental agencies such as OSHA and NIOSH and other sources on hazardous materials. California and some other authorities, for instance, have published lists of substances known to cause cancer, reproductive toxicity, etc.
WARNING
Inhalation of certain dusts, especially organic dusts such as mold or pollen, can cause susceptible persons to have an allergic or asthmatic reaction. Substantial or repeated inhalation of dust and other airborne contaminants, in particular those with a smaller particle size, may cause respiratory or other illnesses. This includes wood dust, especially from hardwoods, but also from some softwoods such as Western Red Cedar. Control dust (such as saw dust) and mists (such as oil mist from
chain lubrication) at the source where possible. Use good work practices, such as always cutting with a properly sharpened saw chain (which produces wood chips rather than fine dust) and operating the unit so that the wind or operating process directs any dust or mist raised by the chain saw away from the operator. Follow the recommendations of EPA/OSHA/NIOSH and occupational and trade associations with respect to dust ("particulate matter"). When the inhalation of dust cannot be substantially controlled, i.e., kept at or near the ambient (background) level, the operator and any bystanders should wear a respirator approved by NIOSH/MSHA for the type of dust encountered.
WARNING
Breathing asbestos dust is dangerous and can cause severe or fatal injury, respiratory illness or cancer. The use and disposal of asbestos-containing products have been strictly regulated by OSHA and the Environmental Protection Agency. Do not use your chain saw to cut or disturb asbestos or asbestos­containing products. If you have any reason to believe that you might be cutting asbestos, immediately stop cutting and contact your employer or a local OSHA representative.
Operating Instructions
WARNING
Always work with the bumper spike so that you have better control of the saw. If you work without the bumper spike the chain saw may pull you forwards suddenly.
WARNING
Never touch a saw chain with your hand or any part of your body when the motor is running, even when the chain is not rotating.
In the event of an emergency, switch off the motor immediately, engage the chain brake by moving the front hand guard to ƒ and remove the battery.
WARNING
Always switch off the motor before putting the chain saw down.
WARNING
The saw chain continues to move for a short period after the trigger switch is fully released.
WARNING
Your chain saw is equipped with a chain catcher. It is designed to reduce the risk of personal injury in the event of a thrown or broken chain. From time to time, the catcher may be damaged or removed. To reduce the risk of personal injury, do not operate a chain saw with a damaged or missing chain catcher.

001BA257 KN
If this chain saw is subjected to unusually high loads for which it was not designed (e. g. heavy impact or a fall), always check that it is in good condition before continuing work. Check in particular that the controls and safety devices are working properly. Do not continue operating this chain saw if it is damaged. In case of doubt, have it checked by your STIHL servicing dealer.
Your chain saw is not designed for prying or shoveling away limbs, roots or other objects. Such use could damage the cutting attachment.
WARNING
When sawing, make sure that the saw chain does not touch any foreign materials such as rocks, fences, nails and the like. Such objects may be flung off, damage the saw chain or cause the chain saw to kickback.
WARNING
If the rotating saw chain strikes a rock or other hard object, sparks may be created, which can ignite flammabale materials under certain circumstances. Flammable materials can include dry vegetation and brush, particularly when weather conditions are hot and dry. Do not use your chain saw around flammable materials or around dry vegetation or brush when there is a risk of fire or wildfire. Contact your local fire authorities or the U.S. Forestry Service if you have any question about whether vegetation and weather conditions are suitable for the use of a chain saw.
WARNING
Take special care when cutting shattered wood because of the risk of injury from slivers being caught and thrown in your direction.
Check the cutting attachment at regular short intervals during operation, or immediately if there is a noticeable change in cutting behavior:
Switch off the motor. Move front hand guard to ƒ. Remove the battery. Check condition and tightness, look
for cracks.
The power tool may be used in rain and wetness. Dry the power tool after finishing work.
Do not leave the machine outdoors in the rain.
DANGER
Do not rely on the chain saw ’s insulation against electric shock. To reduce the risk of electrocution, never operate this chain saw in the vicinity of any wires or cables (power, etc.) which may be carry­ing electric current. To reduce risk of electrocu­tion, take extra precautions when cutting near power lines. Have the power switched off before starting cutting work in the immediate vicinity of power lines.
REACTIVE FORCES INCLUDING KICKBACK
WARNING
Reactive forces may occur any time the chain is rotating. Reactive forces can cause serious personal injury.
The powerful force used to cut wood can be reversed and work against the operator. If the rotating saw chain is suddenly and significantly slowed or stopped by contact with any solid object such as a log or branch or is pinched, the reactive forces may occur instantly. These reactive forces may result in loss of control, which, in turn, may cause serious or fatal injury. An understanding of the causes of these reactive forces may help you avoid the element of surprise and loss of control. Surprise contributes to accidents.
The most common reactive forces are:
kickback, pushback, pull-in.
WARNING
Kickback:
MSA 160 C, MSA 200 C
11
English
001BA035 KN
Kickback may occur when the moving saw chain near the upper quadrant of the bar nose contacts a solid object or is pinched.
When this occurs, the energy driving the saw chain can create a force that moves the chain saw in a direction opposite to the saw chain movement at the point where the saw chain is slowed or stopped. This may fling the bar up and back in a lightning fast reaction mainly in the plane of the bar and can cause severe or fatal injury to the operator.
Kickback may occur, for example, when the saw chain near the upper quadrant of the bar nose contacts the wood or is pinched during limbing or when it is incorrectly used to begin a plunge or boring cut.
The greater the force of the kickback reaction, the more difficult it becomes for the operator to control the chain saw. Many factors influence the occurrence and force of the kickback reaction. These include saw chain speed, the speed at which the bar and saw chain contact the object, the angle of contact, the condition of the saw chain and other factors.
The type of bar and saw chain you use is an important factor in the occurrence and force of the kickback reaction. Some STIHL bar and saw chain types are designed to reduce kickback forces. STIHL recommends the use of reduced kickback bars and low kickback chains.
Chain Saw Kickback Standard
The following standards apply with respect to kickback:
§ 19.108 of UL 60745-2-13 § 5.11 of ANSI/OPEI B175.1-2012
These standards, in the following referred to as "the chain saw kickback standards" set certain performance and design criteria related to chain saw kickback.
To comply with the chain saw kickback standards, electric chain saws
must, in their original condition,
meet a 45° computer derived kickback angle when equipped with certain cutting attachments,
and must be equipped with at least
two devices to reduce the risk of kickback injury, such as a chain brake, low kickback chain, reduced kickback bar, etc.
The computer derived angles for electric saws are measured by applying a computer program to test results from the kickback test machine.
WARNING
The computer derived angles of the chain saw standards may bear no relationship to actual kickback bar rotation angles that may occur in real life cutting situations.
In addition, features designed to reduce kickback injuries may lose some of their effectiveness when they are no longer in their original condition, especially if they have been improperly maintained. Compliance with the chain saw kickback standards does not automatically mean that in a real life kickback the bar and saw chain will rotate at most 45°.
WARNING
In order for chain saws to comply with the computed kickback angle requirements of the chain saw kickback standards use only the following cutting attachments:
bar and saw chain combinations
listed as complying in the "Specifications" section of the instruction manual or
other replacement bar and saw
chain combinations marked in accordance with the standards for use on the chain saw or
replacement saw chain designated

Devices for Reducing the Risk of Kickback Injury
STIHL recommends the use of the STIHL Quickstop chain brake on your chain saw with green labeled reduced kickback bars and low kickback saw chains.
WARNING
To reduce the risk of injury, never use a saw if the chain brake does not function properly. Take the saw to your local STIHL servicing dealer. Do not use the saw until the problem has been rectified.
STIHL Quickstop Chain Brake STIHL has developed a chain stopping
system designed to reduce the risk of injury in certain kickback situations. It is called a Quickstop chain brake.
There are two mechanisms for activating the chain brake if it is in a properly maintained condition:
manual activation: If a kickback
occurs, the chain saw moves upwards towards the user in a rotating motion around the front handle. The brake is designed to engage if the left hand contacts the front guard, which is the activation lever for the brake, and pushes it forward.
inertia activation: All STIHL chain
saws are equipped with an interia Quickstop chain brake. If the kickback impulse is strong enough, this alone is sufficient to engage the brake even without contacting the front hand guard.
WARNING
Never operate your chain saw without a front hand guard. In a kickback situation this guard helps protect your left hand and other parts of your body. In addition, removal of the hand guard on a chain saw equipped with a Quickstop chain brake will disable the activation mechanism of the chain brake.
WARNING
No Quickstop or other chain brake device prevents kickback. These devices are designed to reduce the risk of kickback injury, if activated, in certain kickback situations. In order for the Quickstop to reduce the risk of kickback injury, it must be properly maintained and in good working order. See the chapter of your instruction manual entitled "Chain Brake" and the section "Maintenance, Repair and Storing" at the end of these Safety Precautions. In addition, there must be enough distance between the bar and the operator to ensure that the Quickstop has sufficient time to activate and stop the saw chain before potential contact with the operator.
WARNING
An improperly maintained chain brake may increase the time needed to stop the saw chain after activation, or may not activate at all.
Low Kickback Saw Chain and Reduced Kickback Bars
STIHL offers a variety of bars and saw chains. STIHL reduced kickback bars and low kickback saw chains are
MSA 160 C, MSA 200 C
13
English
designed to reduce the risk of kickback injury. Other saw chains are designed to achieve higher cutting performance or sharpening ease, but in turn are more prone to kickback.
STIHL has developed a color code system to help you identify the STIHL reduced kickback bars and low kickback saw chains. Cutting attachments with green warning labels on the packaging are designed to reduce the risk of kickback injury. The matching of green marked or labeled chain saws with green labeled bars and green labeled saw chains gives compliance with the computed kickback angle requirements of the chain saw standards when the products are in their original condition. Products with yellow labels are for users with extraordinary cutting needs, having experience and specialized training for dealing with kickback.
STIHL recommends the use of its green labeled reduced kickback bars, green labeled low kickback saw chains and a chain saw equipped with a STIHL Quickstop chain brake for both experienced and inexperienced chain saw users.
Please ask your STIHL dealer to properly match your chain saw with the appropriate bar/saw chain combination to reduce the risk of kickback injury. Green labeled bars and saw chains are recommended for all chain saws. See your "STIHL Bar and Chain Information" leaflet for details.
injury. New bar/saw chain combinations may be developed after publication of this literature, which will, in combination with certain electric chain saws, comply with the chain saw standards as well. Check with your STIHL dealer for such combinations.
WARNING
Reduced kickback bars and low kickback saw chains do not prevent kickback, but they are designed to reduce the risk of kickback injury. They are available from your STIHL dealer.
WARNING
Even if your saw is equipped with a Quickstop, a reduced kickback bar and/or low kickback saw chain, this does not eliminate the risk of injury by kickback. Therefore, always observe all safety precautions to avoid kickback situations.
Low Kickback Saw Chain Some types of saw chains have
specially designed components to reduce the force of nose contact kickback. STIHL has developed low kickback saw chains for your chain saw.
A "low kickback saw chain" is a saw chain that has met the kickback performance requirements of ANSI/OPEI B175.1-2012 when tested according to the provisions specified in ANSI/OPEI B175.1-2012.
been specifically certified to comply with the 45° computer derived kickback angle of the chain saw standards. Some low kickback saw chains have not been tested with all chain saw and bar combinations.
WARNING
A blunt or incorrectly sharpened saw chain may reduce or negate the effects of the design features intended to reduce kickback energy. Improper lowering or sharpening of the depth gauges as well as changing the shape of the cutters may increase the risk and the energy of kickback. Always cut with a properly sharpened saw chain.
Reduced Kickback Bars STIHL green labeled reduced kickback
bars are designed to reduce the risk of kickback injury when used with STIHL green labeled low kickback saw chains.
WARNING
When used with other, more aggressive saw chains, these bars may be less effective in reducing kickback.
WARNING
For a properly balanced saw and in order to comply with the chain saw standards, use only bar lengths listed in the specifications chapter of the instruction manual for your chain saw.
WARNING
Use of other, non-listed bar/saw chain combinations may increase kickback forces and increase the risk of kickback

To avoid kickback The best protection from personal injury
that may result from kickback is to avoid kickback situations:
1. Hold the chain saw firmly with both hands and maintain a secure grip. Don’t let go.
2. Be aware of the location of the guide bar nose at all times.
3. Never let the nose of the guide bar contact any object. Do not cut limbs with the nose of the guide bar. Be especially careful near wire fences and when cutting small, tough limbs, small size brush and saplings which may easily catch the saw chain.
4. Don't overreach.
5. Don't cut above shoulder height.
6. Begin cutting and continue at full speed.
7. Cut only one log at a time.
8. Use extreme caution when reentering a previous cut.
9. Do not attempt to plunge cut if you are not experienced with these cutting techniques.
10. Be alert for shifting of the log or other forces that may cause the cut to close and pinch the saw chain.
11. Maintain saw chain properly. Cut with a correctly sharpened, properly tensioned saw chain at all times.
12. Stand to the side of the cutting path of the chain saw.
Bow Guides
WARNING
Do not mount a bow guide on any STIHL chain saw. Any chain saw equipped with a bow guide is potentially very dangerous. The risk of kickback is increased with a bow guide because of the increased kickback contact area. Low kickback saw chain will not significantly reduce the risk of kickback injury when used on a bow guide.
A=Pull-in
Pull-in occurs when the saw chain on the bottom of the bar is suddenly stopped when it is pinched, caught or encounters a foreign object in the wood. The reaction of the saw chain pulls the chain saw forward and may cause the operator to lose control.
Pull-in frequently occurs when the bumper spike of the chain saw is not held securely against the tree or limb and when the saw chain is not rotating at full speed before it contacts the wood.
WARNING
Use extreme caution when cutting small size brush and saplings which may easily catch the saw chain, be whipped towards you or pull you off balance.
To avoid pull-in
1. Always start a cut with the saw chain rotating at full speed and the bumper spike in contact with the wood.
2. The risk of pull-in may also be reduced by using wedges to open the kerf or cut.
B = Pushback
Pushback occurs when the saw chain on the top of the bar is suddenly stopped when it is pinched, caught or encounters a foreign object in the wood. The reaction of the saw chain may drive the chain saw rapidly straight back toward the operator and may cause loss of chain saw control, which, in turn, may cause serious or fatal injury. Pushback frequently occurs when the top of the bar is used for cutting.
MSA 160 C, MSA 200 C
15
English
001BA033 KN
001BA051 LÄ
To avoid pushback
1. Be alert to forces or situations that may cause material to pinch the top of the saw chain.
2. Do not cut more than one log at a time.
3. Do not twist the chain saw when withdrawing the bar from a plunge cut or underbuck cut because the saw chain can pinch.
WARNING
For cutting larger trees, logs or branches, a more powerful, faster and/or steady cut may be necessary to reduce the risk of binding, stalling or a change in conditions during a longer cutting time that could lead to a loss of control of the object being cut and serious personal injury.
The electric chain saw is of only limited suitability for felling and limbing.
If, however, a tree is to be felled and limbed with a an electric chain saw, it is imperative to observe the following instructions.
Do not stand on a log while limbing it – you may slip or the log may roll.
Start limbing by leaving the lower limbs to support the log off the ground. When underbucking freely hanging limbs, a pinch may result or the limb may fall, causing loss of control. If a pinch occurs, switch off the motor, move front hand guard to ƒ, remove the battery and remove the saw by lifting the limb.
WARNING
Be extremely cautious when cutting limbs or logs under tension (spring poles). The limbs or logs could spring back toward the operator and cause loss of control of the saw and severe or fatal injury to the operator.
Bucking
WARNING
When bucking, do not stand on the log. Make sure the log will not roll downhill. If on a slope, stand on the uphill side of the log. Watch out for rolling logs.
Cut only one log at a time. Shattered wood should be cut very
carefully. Sharp slivers of wood may be caught and flung in the direction of the operator of the saw.
Limbing
Limbing is removing the branches from a fallen tree.
WARNING
There is an extreme danger of kickback during the limbing operation. Do not work with the nose of the bar. Be extremely cautious and avoid contacting the log or other limbs with the nose of the guide bar.
16
When cutting small logs, place log through "V"-shaped supports on top of a sawhorse. Never permit another person to hold the log. Never hold the log with your leg or foot.
Bucking is cutting a log into sections.

Logs under strain: Risk of pinching! Always start relieving
cut (1) at compression side.Then make bucking cut (2) at tension side. If the saw pinches, stop the engine and remove it from the log.
Only properly trained professionals should work in an area where the logs, limbs and roots are tangled. Working in "blow down" areas is extremely hazardous. Drag the logs into a clear area before cutting. Pull out exposed and cleared logs first.
WARNING
There are a number of factors that may affect and change the intended direction of fall, e.g. wind direction and speed, lean of tree, surrounding trees and obstacles, sloping ground, one-sided limb structure, wood structure, decay, snow load, etc. To reduce the risk of severe or fatal injury to yourself or others, look for these conditions prior to beginning the cut, and be alert for a change in direction while the tree is falling.
WARNING
Always observe the general condition of the tree. Inexperienced users should never attempt to cut trees that are decayed or rotted inside or that are leaning or otherwise under tension. There is an increased risk that such trees could snap or split while being cut and cause serious or fatal injury to the operator or bystanders. Also look for broken or dead branches which could vibrate loose and fall on the operator. When felling on a slope, the operator should stand on the uphill side if possible.
Felling Instructions
When felling, maintain a distance of at least 2 1/2 tree lengths from the nearest person.
When felling in the vicinity of roads, railways and power lines, etc., take extra precautions. Inform the police, utility company or railway authority before beginning to cut.
WARNING
The noise of your engine may drown any warning call.
Felling
Felling is cutting down a tree. Before felling a tree, consider carefully
all conditions which may affect the direction of fall.

Escape Path
First clear the tree base and work area from interfering limbs and brush and clean its lower portion with an ax.
Then, establish two paths of escape (B) and remove all obstacles. These paths should be generally opposite to the planned direction of the fall of the tree (A) and about at a 45° angle. Place all tools and equipment a safe distance away from the tree, but not on the escape paths.
Buttress Roots
If the tree has large buttress roots, cut into the largest buttress vertically first (horizontally next) and remove the resulting piece.
Gunning Sight
When making the felling notch, use the gunning sight on the shroud and housing to check the desired direction of fall:
Position the saw so that the gunning sight points exactly in the direction you want the tree to fall.
Conventional Cut
Felling notch (C) – determines the direction of the fall
For a conventional cut: N Properly place felling notch
perpendicular to the line of fall, close to the ground.
N Cut down at approx. 45° angle to a
depth of about 1/5 to 1/4 of the trunk diameter.
N Make second cut horizontal. N Remove resulting 45° piece.

Open-face Technique
Felling notch (C) – determines the direction of the fall
For an open-face cut: N Properly place felling notch
perpendicular to the line of fall, close to the ground.
N Cut down at approx. 50° angle to a
depth of approx.1/5 to 1/4 of the trunk diameter.
N Make second cut from below at
approx. 40 degree angle.
N Remove resulting 90° piece.
Making Sapwood Cuts
N For medium sized or larger trees
make cuts at both sides of the trunk, at same height as subsequent felling cut.
N Cut to no more than width of guide
bar.
This is especially important in softwood in summer – it helps prevent sapwood splintering when the tree falls.
D =Felling Cut
Conventional and open-face technique: N Begin 1 to 2 inches (2,5 to 5 cm)
higher than center of felling notch.
N Cut horizontally towards the felling
notch.
N Leave approx.1/10 of diameter
uncut. This is the hinge.
N Do not cut through the hinge – you
could lose control of the direction of the fall.
Drive wedges into the felling cut where necessary to control the fall.
WARNING
If the tip of the bar contacts a wedge, it may cause kickback. Wedges should be of wood or plastic – never steel, which can damage the chain.

Felling Cut for Small Diameter Trees: Simple Fan Cut
Engage the bumper spikes of the chain saw directly behind the location of the intended hinge and pivot the saw around this point only as far as the hinge. The bumper spike rolls against the trunk.
Felling Cut for Large Diameter Trees
WARNING
Felling a tree that has a diameter greater than the length of the guide bar requires use of either the sectioning felling cut or plunge-cut method. These methods are extremely dangerous because they involve the use of the nose of the guide bar and can result in kickback. Only properly trained professionals should attempt these techniques.
Sectioning Method For the sectioning method make the first
part of the felling cut with the guide bar fanning in toward the hinge. Then, using the bumper spike as a pivot, reposition the saw for the next cut.
20
MSA 160 C, MSA 200 C
Avoid repositioning the saw more than

necessary. When repositioning for the next cut, keep the guide bar fully engaged in the kerf to keep the felling cut straight. If the saw begins to pinch, insert a wedge to open the cut. On the last cut, do not cut the hinge.
Plunge-cut Method Timber having a diameter more than
twice the length of the guide bar requires the use of the plunge-cut method before making the felling cut.
First, cut a large, wide felling notch. Make a plunge cut in the center of the notch.
The plunge cut is made with the guide bar nose. Begin the plunge cut by applying the lower portion of the guide bar nose to the tree at an angle. Cut until the depth of the kerf is about the same as the width of the guide bar. Next, align the saw in the direction in which the recess is to be cut.
With the saw at full throttle, insert the guide bar in the trunk.
Enlarge the plunge cut as shown in the illustration.
WARNING
There is an extreme danger of kickback at this point. Extra caution must be taken to maintain control of the saw. To make the felling cut, follow the sectioning method described previously.
If you are inexperienced with a chain saw, plunge-cutting should not be attempted. Seek the help of a professional.
English
WARNING
In order to reduce the risk of personal injury, never stand directly behind the tree when it is about to fall, since part of the trunk may split and come back towards the operator (barber-chairing), or the tree may jump backwards off the stump. Always keep to the side of the falling tree. When the tree starts to fall, withdraw the bar, shut off the engine and walk away on the preplanned escape path. Watch out for falling limbs.
WARNING
Be extremely careful with partially fallen trees which are poorly supported. When the tree hangs or for some other reason does not fall completely, set the saw aside and pull the tree down with a cable winch, block and tackle or tractor. If you try to cut it down with your saw, you may be injured.
MAINTENANCE, REPAIR AND STORING
If you make a warranty claim for a component which has not been serviced or maintained properly or if nonapproved replacement parts were used, STIHL may deny coverage.
WARNING
Use only identical STIHL replacement parts for maintenance and repair. Use of non-STIHL parts may cause serious or fatal injury.
MSA 160 C, MSA 200 C
21
English
Strictly follow the maintenance and repair instructions in the appropriate section of your instruction manual. Please also refer to the maintenance chart in this manual.
Always switch off the motor, move front hand guard to ƒ, remove the battery from the power tool and make sure that the cutting tool is stopped before carrying out any maintenance or repair work, such as replacing the cutting attachment, or cleaning the power tool. This avoids the risk of the motor starting unintentionally.
WARNING
Do not attempt any maintenance or repair work not described in your instruction manual. Have such work performed by your STIHL servicing dealer only.
Wear gloves when handling or performing maintenance on saw chains.
Keep the chain, bar and sprocket clean; replace worn sprockets or chains. Keep the chain sharp. You can spot a dull chain when easy-to-cut wood becomes hard to cut and burn marks appear on the wood. Keep the chain at proper tension.
Always replace the chain, guide bar and sprocket as necessary.
Tighten all nuts, bolts and screws after each use.
WARNING
In order for the chain brake on your STIHL chain saw to properly perform its function of reducing the risk of kickback and other injuries, it must be properly maintained. Like an automobile brake, a chain saw chain brake incurs wear each time it is engaged.
The amount of wear will vary depending upon usage, conditions under which the saw is used and other factors. Excessive wear will reduce the effectiveness of the chain brake and can render it inoperable.
For the proper and effective operation of the chain brake, the brake band and chain sprocket drum must be kept free of dirt, grease and other foreign matter which may reduce friction of the band on the drum.
For these reasons, each STIHL chain saw should be returned to trained personnel such as your STIHL servicing dealer for periodic inspection and servicing of the brake system according to the following schedule:
Heavy usage – every three months, Moderate usage – twice a year, Occasional usage – annually.
The chain saw should also be returned immediately for maintenance whenever the brake system cannot be thoroughly cleaned or there is a change in its operating characteristics.
Regularly check the electrical contacts and ensure that the insulation of the power cord and plug of the charger is in good condition and shows no sign of aging (brittleness).
Electrical components, e.g. power cord of charger, may only be repaired or replaced by a qualified electrician.
Keep the battery guides free from foreign matter – clean as necessary.
Do not spray the machine with water. Do not clean your machine with a
pressure washer. The solid jet of water may damage parts of the machine.
Clean plastic components with a cloth. Do not use aggressive detergents. They may damage the plastic.
Store chain saw in a dry, locked location with the front hand guard on ƒ, the battery removed and out of reach of children (see chapter "Storing the Machine" in the instruction manual).

General Power Tool Safety Warnings
This chapter relays the prescribed wording of general safety advice for handheld motor-operated electric chain saws contained in UL 60745-1 and UL 60745-2-13.
The safety precautions and warnings on avoiding an electric shock given under "2) Electrical safety" do not apply to STIHL cordless electric power tools.
WARNING
Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b) Do not operate power tools in
explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away
while operating a power tool. Distractions can cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the
outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or
grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
c) Do not expose power tools to rain or
wet conditions. Water entering a power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use
the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
e) When operating a power tool
outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp
location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing
and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
b) Use personal protective equipment.
Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting.
Ensure the switch is in the off­position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
d) Remove any adjusting key or
wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper
footing and balance at all times. This enables better control of the power tool in unexpected situations.
MSA 160 C, MSA 200 C
23
English
f) Dress properly. Do not wear loose
clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
g) If devices are provided for the
connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
4) Power tool use and care
a) Do not fo rce the pow er tool . Use th e
correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the
switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power
source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
d) Store idle power tools out of the
reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
e) Maintain power tools. Check for
misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories
and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
5) Battery tool use and care
a) Recharge only with the charger
specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
b) Use power tools only with
specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
c) When battery pack is not in use,
keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
d) Under abusive conditions, liquid
may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
6) Service
a) Have your power tool serviced by a
qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Chain saw safety warnings
Keep all parts of the body away
from the saw chain when the chain saw is operating. Before you start the chain saw, make sure the saw chain is not contacting anything. A moment of inattention while operating chain saws may cause entanglement of your clothing or body with the saw chain.
Always hold the chain saw with your
right hand on the rear handle and your left hand on the front handle. Holding the chain saw with a reversed hand configuration increases the risk of personal injury and should never be done.
Hold the power tool by insulated
gripping surfaces only, because the saw chain may contact hidden wiring. Saw chains contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.
Wear safety glasses and hearing
protection. Further protective equipment for head, hands, legs and feet is recommended. Adequate protective clothing will reduce personal injury by flying debris or accidental contact with the saw chain.
Do not operate a chain saw in a
tree. Operation of a chain saw while up in a tree may result in personal injury.
Always keep proper footing and
operate the chain saw only when standing on fixed, secure and level surface. Slippery or unstable surfaces such as ladders may cause a loss of balance or control of the chain saw.
When cutting a limb that is under
tension be alert for spring back. When the tension in the wood fibers is released the spring loaded limb may strike the operator and/or throw the chain saw out of control.
Use extreme caution when cutting
brush and saplings. The slender material may catch the saw chain and be whipped toward you or pull you off balance.
Carry the chain saw by the front
handle with the chain saw switched off and away from your body. When transporting or storing the chain saw always fit the guide bar cover. Proper handling of the chain saw will reduce the likelihood of accidental contact with the moving saw chain.
Follow instructions for lubricating,
chain tensioning and changing accessories. Improperly tensioned or lubricated chain may either break or increase the chance for kickback.
Keep handles dry, clean, and free
from oil and grease. Greasy, oily handles are slippery causing loss of control.
Cut wood only. Do not use chain saw for purposes not intended. For example: do not use chain saw for cutting plastic, masonry or non­wood building materials. Use of the chain saw for operations different than intended could result in a hazardous situation.
Causes and operator prevention of kickback
Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut.
Tip contact in some cases may cause a sudden reverse reaction, kicking the guide bar up and back towards the operator.
Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator.
Either of these reactions may cause you to lose control of the saw which could result in serious personal injury. Do not rely exclusively upon the safety devices built into your saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury.

Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:
Maintain a firm grip, with thumbs
and fingers encircling the chain saw handles, with both hands on the saw and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator, if proper precautions are taken. Do not let go of the chain saw.
Do not overreach and do not cut
above shoulder height. This helps prevent unintended tip contact and enables better control of the chain saw in unexpected situations.
Only use replacement bars and
chains specified by the manufacturer. Incorrect replacement bars and chains may cause chain breakage and/or kickback.
Follow the manufacturer's
sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback.
Cutting Attachment
A cutting attachment consists of the saw chain, guide bar and chain sprocket.
The cutting attachment that comes standard is designed to exactly match the chain saw.
The pitch (t) of the saw chain (1),
chain sprocket and the nose sprocket of the Rollomatic guide bar must match.
The drive link gauge (2) of the saw
chain (1) must match the groove width of the guide bar (3).
If non-matching components are used, the cutting attachment may be damaged beyond repair after a short period of operation.
Chain scabbard
Your saw comes standard with a chain scabbard that matches the cutting attachment.
If you use guide bars of different lengths on the saw, the length of the chain scabbard must be matched to the guide bar to reduce the risk of injury. It should cover the full length of the guide bar.
The length of the matching guide bars is marked on the side of the chain scabbard.
