GENERAL POWER TOOL SAFETY WARNINGS

IMPORTANT SAFETY WARNINGS

2

WARNING: Read all safety warnings and 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.

Work area safety

 Keep work area clean and well lit. Cluttered or dar k

areas invite accidents.

 Do not operate power tools in explosive atmospheres,

such as in the presence of flammable liquids, gases or dust. Power t ools create sparks which may ignite the

dust or fumes.

 Keep children and bystanders away while operating a

power tool. Distractions can cause you to lose control.

Electrical safety

 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.

 Avoid body contact with earthed or grounded

surfaces such as pipes, radiators, ranges and refrigerators. There is an increas ed r is k of electric

shock if your body is earthed or grounded.

 Do not expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of electric shock.

 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.

 When operating a power tool outdoors, use an

extension cord suitable for outdoor use. Use of a c or d suitable for outdoor use reduces the risk of electric shock.

 If operating a power tool in a damp location is

unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the

risk of electric shock.

Personal safety

 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.

 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.

 Prevent unintentional starting. Ensure the switch is in

the off-position 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.

 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.

 Do not overreach. Keep proper footing and balance at

all times. This enables better control of the power tool in unexpected situations.

 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.

 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.

Power tool use and care

 Do not force the power tool. Use the correct power

tool for your application. The c or rect power tool will do the job better and safer at the rate for which it was designed.

 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.

GENERAL POWER TOOL SAFETY WARNINGS

 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 r educe the risk

of starting the power tool accidentally.

 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.

 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.

 Keep cutting tools sharp and clean. Proper ly

maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

 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 t he power tool for oper ations

different from those intended could result in a hazardous situation.

Service

 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.

 When servicing a power tool, use only identical

replacement parts. Follow instructions in the Maintenance section of this manual. Use of

unauthorized parts or failure to follow Maintenance instructions may create a risk of shock or injury.

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 or its own cord. 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. Adeq uate protective clot hi ng 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 c atc h t he 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 non-wood building materials. Use of the chain saw for operations

different than intended could result in a hazardous situation.

CHAIN SAW SAFETY WARNINGS

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:

It is possible to tie the extension cord and power cord in a knot to prevent them from becoming disconnected during use. Make the knot as shown, then connect the plug end of the power cord into the receptacle end of the extension cord. This method can also be used to tie two extension cords together.

WARNING: CALIFORNIA PROPOSITION 65 This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

WARNING: Some dust and debr is created by this product could contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

-chemicals in fertilizers

-compounds in insecticides, herbicides and pesticides

-arsenic and chromium from chemically treated lumber

Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.

DOUBLE INSULATION – Double Insulation is a concept in safety in electric power tools, which eliminates the need for the usual three-wire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated tools do not need to be grounded. NOTE: The double insulated system is intended to protect the user from shock resulting from a break in the tool’s internal insulation. Observe all normal safety precautions to avoid electrical shock.

POLARIZED PLUGS – To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider than the other). This equipment must be used with a suitable polarized 2 wire or 3 wire extension cord. Polarized connections will fit together only one way. Make sure that the receptacle end of the extension cord has large and small blade slot widths. If the plug does not fit fully into the extension cord, reverse the plug. If it still does not fit, obtain a suitable extension cord. If the extension cord does not fit fully into the outlet, contact a qualified electrician to install the proper outlet. Do not change the tool plug or extension cord in any way.

WARNING: Use outdoor extension cords marked SW-A, SOW-A, STW-A, STOW-A, SJW-A, SJTW-A, or SJTOWA. These cords are rated for outdoor use and reduce the risk of electric shock.

EXTENSION CORD. Make sure your extension cord is in good condition. When using an extension cord be sure it is heavy enough to carry the current your product will draw. An undersized extension cord will cause a drop in line voltage resulting in loss of power and overheating. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

 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. Incorr ect 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.

 Replace the chain drive links into the bar groove.

NOTE: Make c ertain of the direction of chain.

 Position the chain so there is a loop at the back of the

bar.

 Hold the chain in position on the bar and place the loop

around the sprocket. Raise it to an angle of approx..45 degrees. This will make it easier to place the saw chain onto the sprocket. It is normal that the saw chain is slack.

 Pre-tighten the chain tension by turning the tension plate

clockwise.

 Replace the chain cover. Secure by turning the chain

cover knob clockwise. Only lightly tighten the knob as you will still need to tension the saw chain.

TENSIONING THE SAW CHAIN

 To tighten the chain, turn the tensioning wheel clockwise.

To loosen the tension, turn the tensioning wheel counterclockwise.

 Tighten the chain cover knob by turning it clockwise.

 Re-adjust tension of the saw chain when necessary.

The chain is correctly tensioned when there is no sag on the underside of the guide bar, the chain is snug, but it can be turned by hand without binding.

NOTE: If c hain is too tight, it will not rotate. Loosen by turning the tensioning wheel. Ensure that the chain will rotate without binding.

NOTE: A new chain tends t o s tr etch, check chain t ension frequently and tension as required.

REPLACING THE BAR

 Disconnect chain saw from power supply.

 Use a Phillips head screw driver to remove the fixing

screw. Remove the tension plate from the old bar.

 Attach the tension plate to the new bar. Make sure the

round end of the clamping plate is placed in the direction as shown below and the clamping bolt is placed at the bottom. Tighten the fixing screw.

OPERATING

TO TURN THE TOOL ON

Push the lock button in with your thumb and then squeeze the trigger with your fingers. (Once the tool is running, you can release the lock button). To turn the tool OFF, release the trigger.

WARNING: To guard agains t i njury, observe the follow ing:

- Read instruction manual before using, save instruction manual.

- Keep hands away from chain.

- Keep hands on handles. Don’t overreach.

A good, firm grip on the saw with both hands will help you maintain control. Don’t let go. Grip the rear handle with your right hand whether you are right or left handed. Wrap the fingers of your left hand over and around the front handlebar, and your left thumb under the front handlebar.

WARNING: Do not operate chain saw in a tree, on a lad der, or on a scaffold; this is extremely dangerous.

CAUTION: Chain coasts after tur ned off. Do not use under wet conditions.

Use extreme caution when cutting small size brush, saplings or limbs under tension, because slender and tense material may catch the saw and be whipped toward you, pull you off balance or spring back.

Do not cut vines and/or small underbrush.

WARNING: Do not allow familiarity w ith this type of tool to make you careless. Remember that a careless fraction of a second is sufficient to inflict serious injury.

Before you start the unit, make sure the chain saw is not contacting any object.

WARNING: Do not cu t trees near electrical wires or buildings.

Make sure you follow the instructions in maintenance for putting oil

in the chain saw.

CAUTION: Failure to lubricate the c hain wi ll caus e damage to the bar and chain. Use only a good quality bar and chain oil or, if not available, unused SAE 30 weight motor oil may be substituted. One minute of use will consume approx. 0.2 fl. oz. (6ml) of oil.

NOTE: It is normal for oil to seep fr om the saw when not i n use. To prevent seepage, empty the oil tank after each use. When storing the unit for a long period of time (3 months or longer) be sure the chain is lightly lubricated; this will prevent rust on the chain and bar sprocket.

WARNING: Kickback may occur when the moving chain contacts an object at the upper portion of the tip of the guide bar or when the wood closes in and pinches the chain saw in the cut. Contact at the upper portion of the tip of the guide bar can cause the chain to dig into the object and stop the chain for an instant. The result is a lightening fast, reverse reaction which kicks the guide bar up and back toward the operator. If the chain saw is pinched along the top of the guide bar, the guide bar can be driven

rapidly back toward the operator. Either of these reactions can

cause loss of saw control which can result in serious injury. Do not rely exclusively upon the safety devices built into the saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury.

WARNING: Do Not use the ch ain saw with any type of accessory or attachment. Such usage might be hazardous.

The following precautions should be followed to minimize kickback:

1. Always grip the saw firmly with both hands. Hold the saw firmly with both hands when the unit is running. Place your right hand on the rear handle and your left hand on the front handle with your thumbs and fingers encircling the chain saw handles. A firm grip together with a stiff left arm will help you maintain control of the saw if kickback occurs.

2. Make sure that the area in which you are cutting is free from obstructions. Do not let the nose of the guide bar contact a log, branch, fence or any other obstruction that could be hit while you are operating the saw.

3. Always cut with the unit running at full speed. Fully squeeze the throttle trigger and maintain a steady cutting speed.

Push and Pull – This reaction force is always opposite to the direction the chain is moving where wood contact is made. Thus, the operator must be ready to control the PULL when cutting on the bottom edge of the bar, and PUSH when cutting along the top edge.

Wear non-slip gloves for maximum grip and protection.

Proper Cutting Stance

Weight should be balanced with both feet on solid ground.

Keep left arm with elbow locked in a “straight arm” position to withstand any kickback force.

Your body should always be to the left of the chain line.

Basic Cutting Procedure

Small trees up to 6-7inches in diameter are usually cut in a single

cut. Large trees require notch cuts. Notch cuts determine the

direction the tree will fall.

WARNING: If the tree starts to fall in the wrong direction, or if the saw gets caught or hung up during the fall, leave the saw and save yourself.

WARNING: Periodic ally glance at th e top of the tree during the back-cut to assure the tree is going to fall in the desired direction.

Practice cutting a few small logs using the following technique to

get the “feel” of using the saw before you begin a major sawing operation.

Take the proper stance in front of the wood with the saw off.

Squeeze the trigger and let the chain accelerate to full speed before entering the cut.

Hold the saw firmly with both hands. Always keep your left hand on the front handle and your right hand on the rear handle so that your body is to the left of the chain line.

8

OPERATING

Keep the unit running the entire time you are cutting, maintain a steady speed.

Allow the chain to cut for you; exert only light downward pressure. If you force the cut, damage to the bar, chain, or unit can result.

Do not put pressure on the saw at the end of the cut.

When felling a tree, keep everyone a safe distance from the cutting area. During felling operations, the safe distance should be at least twice the height of the largest trees in the felling area. If the tree makes contact with any utility line, the utility company should be notified immediately.

Always cut with both feet on solid ground to prevent being pulled off balance.

Do not cut above chest height, as a saw held higher is difficult to control against kickback forces.

FELLING A TREE

When bucking and felling operations are being performed by two or more persons, at the same time, the felling operation should be separated from the bucking operation by a distance of at least twice the height of the tree being felled. Trees

should not be felled in a manner that would endanger any

person, strike any utility line or cause any property damage. If the tree does make contact with any utility line, the utility company should be notified immediately.

WARNING: Check the tree f or dam aged or dead branches that could fall and hit you during felling.

Before any cuts are started, pick your escape route (or routes in case the intended route is blocked); clear the immediate area around the tree and make sure there are no obstructions in your planned path of retreat. A clear path of safe retreat is approximately 135 degrees from planned line of fall. The retreat path should extend back and diagonally to the rear of the expected line of fall.

Before felling is started, consider the force and direction of the wind, the lean and balance of the tree, and the location of large limbs. These things influence the direction in which the tree will fall. Do not try to fell a tree along a line different from its natural line of fall.

The chain saw operator should keep on the uphill side of the terrain as the tree is likely to roll or slide downhill after it is felled.

Remove dirt, stones, loose bark, nails, staples, and wire from the tree where felling cuts are to be made.

NOTCHED UNDERCUT – Cut a notch about 1/3 diameter of the tree, perpendicular to the direction of the fall. Make the cuts of the notch so they intersect at a right angle to the line

of fall. This notch should be cleaned out to leave a straight

line. To keep the weight of the wood off the saw, always make the lower cut of the notch before the upper cut.

WARNING: Do not fell trees during periods of high w in d or heavy precipitation. Wait to do your cutting until the hazard has ended.

WARNING: Do not cut down trees having an ex treme lean

or large trees that have rotten limbs, loose bark, or hollow

trunks. Have these trees pushed or dragged down with heavy equipment, then cut them up.

FELLING BACK-CUT

The back-cut is always made level and horizontal, and at a minimum of 2 inches (5cm) above the horizontal cut of the notch.

Never cut through to the notch. Always leave a band of wood between the notch and back-cut (approximately 2 inches (5cm) or 1/10 the diameter of the tree). This is called “hinge” or “hinge wood.” It controls the fall of the tree and prevents slipping or twisting or shoot-back of the tree off the stump.

On large diameter trees, stop the back cut before it is deep enough for the tree to either fall or settle back on the stump. Then insert soft wooden or plastic wedges into the cut so they do not touch the chain. The wedges can be driven in, little by little, to help jack the tree over.

OPERATING

CUTTING INSTRUCTIONS

LIMBING

Limbing is removing branches from a fallen tree.

Work slowly, keeping both hands on the chain saw with a firm grip. Always make sure your footing is secure and your weight is distributed

evenly on both feet.

Leave the larger support limbs under the tree to keep the tree off the ground while cutting.

Limbs should be cut one at a time. Remove the cut limbs from the work area often to help keep the work area clean and safe.

Branches under tension should be cut from the bottom up to avoid binding the chain saw.

Keep the tree between you and the chain saw while limbing. Cut from the side of the tree opposite the branch you are cutting.

WARNING: Never climb into a tree t o limb or pr un e. Do not stand on ladders, platforms, a log, or in any position which can cause you to lose your balance or control of the saw.

PRUNING

Pruning is trimming limbs from a live tree.

Work slowly, keeping both hands on the chain saw with a firm grip. Always make sure your footing is secure and your weight is distributed evenly on both feet.

When pruning trees it is important not to make the finishing cut next to the main limb or trunk until you have cut off the limb further out to reduce the weight. This prevents stripping the bark from the main

member.

Under-buck the branch 1/3 through for your first cut. Your second cut should over-buck to drop the branch off. Now make your finishing cut smoothly and neatly against the main member so the bark will grow back to seal the wound.

WARNING: SPRINGPOLES

A springpole is any log, branch, rooted stump, or sapling which is bent under tension by other wood so that it springs back if the wood holding it is cut or removed. On a fallen tree, a rooted stump has a high potential of springing back to the upright position during the bucking cut to separate the log from the stump. Watch out for springpoles, they are dangerous. They could result in severe or fatal injury.

As the tree starts to fall, stop the chain saw and put it down immediately. Retreat along the cleared path, but watch the action in case something falls your way. Be alert for overhead limbs or branches that may fall and watch your footing.

WARNING: Never cut through to the notch when making a back-cut. The hinge controls the fall of the tree, this is a section of wood between the notch and back-cut.

BUCKING

Bucking is the term used for cutting a fallen tree to the desired log length.

Always make sure your footing is secure and your weight is distributed evenly on both feet.

Cut only one log at a time. Support small logs on a saw horse or

another log while bucking.

Keep a clear cutting area. Make sure that no objects can contact the guide bar nose and chain during cutting, this can cause kickback.

When bucking on a slope, always stand on the uphill side of the log. To maintain complete control of the chain saw when cutting through the log, release the cutting pressure near the end of the cut without relaxing your grip on the chain saw handles. Do not let the chain contact the ground. After completing the cut, wait for the saw chain to stop before you move the chain saw. Always stop the motor

before moving from tree to tree.

BUCKING LOGS UNDER STRESS

When the log is supported along its entire length, it should be cut from the top or over-bucking.

When the log is supported on one end, cut 1/3 diameter from the underside or under-bucking. Then make the finishing cut by over-bucking to meet the first cut.

As the log is being cut, it will tend to bend. The saw can become

pinched or hung in the log if you make the first cut deeper than 1/3 of the diameter of the log.

Give special attention to logs under stress to prevent the bar and chain from pinching.

OVERBUCKING – Begin on the top side of the log with the bottom of the saw against the log; exert light pressure downward. Note that the saw will tend to pull away from you.

UNDER-BUCKING – Begin on the under side of the log with the top of the saw against the log; exert light pressure upward. During under-bucking, the saw will tend to push back at you. Be prepared for this reaction and hold the saw firmly to maintain control.

CHAIN TENSION AND MAINTENANCE

CHAIN TENSION

Stop the engine before setting the chain tension. Make sure the guide bar screw is loosened to finger tight, turn the tensioning wheel up or down to tension the chain. A cold chain will be correctly tensioned when there is no slack on the underside of the guide bar, the chain is snug, but it can be turned by hand without binding.

Chain must be re-tensioned whenever the flats on the drive links hang

out of the bar groove.

During normal saw operation, the temperature of the chain will increase. The drive links of a correctly tensioned warm chain will hang approximately .050 in. (1.25mm) out of the bar groove. Be aware that chain tensioned while warm, may be too tight upon cooling. Check the “cold tension” before next use.

NOTE: A new chain tends t o stretc h, check chain tens io n frequently and tension as required.

CHAIN MAINTENANCE

CAUTION: Disconnect from the power sup ply an d make sure t he

chain has stopped before you do any work on the saw.

For smooth and fast cutting, chain needs to be maintained properly. The chain requires sharpening when the wood chips are small and powdery, the chain must be forced through the wood during cutting, or the chain cuts to one side. During maintenance of your chain remember:

- Improper filing angle of the side plate can increase the risk of severe kickback.

- Raker (depth gauge) clearance.

- Too low increases the potential for kickback.

- Not low enough decreases cutting ability.

- If cutter teeth have hit hard objects such as nails and stones, or

have been abraded by mud or sand on the wood, have service dealer sharpen chain.

NOTE: Inspect th e drive spr oc ket for wear or damage w hen replacing the chain. If signs of wear or damage are present in the areas indicated, have the drive sprocket replaced by a qualified individual. Call our customer service help line at 1-800-313-5111 for assistance.

HOW TO SHARPEN THE CUTTERS

Be careful to file all cutters to the specified angles and to the same length, as fast cutting can be obtained only when all cutters are uniform.

Wear gloves for protection. Properly tension the chain prior to sharpening. Refer to “Chain Tension Section” earlier in this manual. Do all of your filing at the midpoint of the bar.

Use a 5/32 in. diameter round file and holder.

Keep the file level with the top plate of the tooth. Do not let the file dip or rock. Using light but firm pressure, stroke towards the front corner of the tooth.

Lift file away from the steel on each return stroke.

Put a few firm strokes on every tooth. File all left hand cutters in one direction. Then move to the other side and file

the right hand cutters in

the opposite direction. Occasionally remove filing from the file with a wire brush.

WARNING: Improper c hain sharp eni ng increases t he potenti al o f kickback.

WARNING: Failure to r eplace or repair damaged chai n can cause serious injury.

WARNING: The saw chain is very sharp, always wear protective gloves when performing maintenance to the chain.

TOP PLATE FILING ANGLE

Correct 30 degrees – File holders are marked with guide marks to align file properly to produce top plate angle.

Less than 30 degrees – for cross cutting.

More than 30 degrees – feathered edge dulls quickly.

SIDE PLATE ANGLE

Correct – 80 degrees produced automatically if correct diameter file is used in file holder.

Hook – “Grabs” and dulls quickly. Increases potential of kickback. Results from using a file with a diameter too small, or file held too low.

Backward Slope – Needs too much feed pressure, causes excessive wear to bar and chain. Results from using a file with a diameter too large, or file held too high.

DEPTH GAUGE CLEARANCE

The depth gauge should be maintained at a clearance of .025 in. (0.6 mm). Use a depth gauge tool for checking the depth gauge clearances.

Every time the chain is filed, check the depth gauge clearance

Use a flat file and a depth gauge jointer to lower all gauges uniformly. Depth gauge jointers are available in .020 in. to .035 in. (0.5 mm to 0.9 mm). Use a .025 in. (0.6 mm) depth gauge jointer. After lowering each depth gauge, restore original shape by rounding the front. Be careful not to damage adjoining drive links with the edge of the file.

Depth gauges must be adjusted with the flat file in the same direction the adjoining cutter was filed with the round file. Use care not to contact cutter face with flat file when adjusting depth gauges.

Approx. .050 (1.25mm)

MAINTENANCE

If you drop the chain saw, carefully inspect it for damage. If the blade is bent, housing cracked, or handles broken or if you see any other condition that may affect the saw’s operation, call our customer service line at 1-800-313-5111 for assistance.

Make sure the unit is disconnected from the power supply, then use only mild soap and a damp cloth to clean the tool. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.

IMPORTANT: To assure product SAFETY and RELIAB ILITY, repairs, maintenance and adjustment should be performed by a qualified individual always using identical replacement parts.

CAUTION: Do not at any time let br ake fluids , gasoline, petroleum based products, penetrating oils, etc., come in contact with plastic parts. They contain chemicals that can damage, weaken or destroy plastic.

Ensure that the plastic bar cover is in place when storing.

Fertilizers and other garden chemicals contain agents which greatly accelerate the corrosion of metals Do not store the tool on or adjacent to fertilizers or chemicals.

For smooth and fast cutting, chain needs to be maintained properly. The chain requires sharpening when the wood chips are small and powdery, the chain must be forced through the wood

during cutting, or the chain cuts to one side. Refer to instructions

earlier in this manual for instructions on properly sharpening the chain.

LUBRICATION SYSTEM

BEFORE USING : Fill oil well with new quality bar and chain oil, or if unavailable, unused SAE 30 weight motor oil may be substituted.

The chain is automatically lubricated.

Use only new bar and chain oil or unused SAE 30 weight motor oil may be substituted. Never use wasted oil, low quality oil, or insufficient

oil. This could damage the pump; the bar and the chain which may

result in serious personal injury. Check oil level before each work session, refill if less than ¼ full.

If the lubrication system does not work properly, check if the oil filter and all oil-ways are clean and free from obstructions. If it is still not working, call our customer service line at 1-800-313-5111 for assistance.

GUIDE BAR MAINTENANCE

When the guide bar shows signs of wear, reverse it on the saw to distribute the wear for maximum bar life. The bar should be cleaned

every day of use and checked for wear and damage.

Feathering or burring of the bar rails is a normal process of bar wear. Such faults should be smoothed with a file as soon as they occur.

A bar with any of the following faults should be replaced.

- Wear inside the bar rails which permits the chain to lay over sideways.

- Bent guide bar

- Cracked or broken rails

- Spread rails

In addition, guide bars with a sprocket at their tip must be lubricated

weekly with a grease syringe to extend the guide bar life. Using a

grease syringe, lubricate weekly in the lubricating hole.

Turn the guide bar and check that the lubrication holes and chain groove are free from obstructions.

Problem

- Unit does not run
