Safety Precautions and Working Techniques

Because a KombiEngine equipped with a trimmer KombiTool is a highspeed 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 manuals and the safety precautions of your KombiEngine and KombiTool periodically. Careless or improper use may cause serious or fatal injury.

Have your STIHL dealer show you how to operate your power tool. Observe all applicable local safety regulations, standards and ordinances.

The term "trimmer" is used to designate an FS unit that is equipped with a nylon line head or a head with flexible plastic blades (i.e., the Polycut head). FS models with an "R" on the nameplate were originally configured (at the time of distribution) as a trimmer with a loop handle.

WARNING

As more fully explained later in these Safety Precautions, to reduce the risk of personal injury, make sure your unit is equipped with the proper handle, harness and deflector for the type of

cutting attachment you are using. Use only cutting attachments that are specifically authorized by STIHL for use on your KombiEngine model. To reduce the risk of severe or fatal injury from blade contact and / or loss of control, never attempt to use a metal blade on this trimmer.

WARNING

Do not lend or rent your power tool without the instruction manuals of your KombiEngine and KombiTool. Be sure that anyone using it understands the information contained in these manuals.

WARNING

The use of this machine may be hazardous. If the rotating line or blade comes in contact with your body, it will cut you. When it comes in contact with solid foreign objects such as rocks or bits of metal, it may fling them directly or by ricochet in the direction of bystanders or the operator. Striking such objects could damage the cutting attachment. Thrown objects, including broken heads or polymer blades, may result in serious or fatal injury to the operator or bystanders.

Use your KombiEngine equipped with the appropriate KombiTool only for cutting grass and similar material.

WARNING

Do not use it for other purposes, since misuse may result in personal injury or property damage, including damage to the machine.

WARNING

Minors should never be allowed to use this power tool. Bystanders, especially children, and animals should not be allowed in the area where it is in use.

WARNING

To reduce the risk of injury to bystanders and damage to property, never let your power tool run unattended. When it is not in use (e.g. during a work break), shut it off and make sure that unauthorized persons do not use it.

Most of these safety precautions and warnings apply to the use of all STIHL power tools. Different models may have different parts and controls. See the appropriate section of your KombiEngine and KombiTool instruction manuals for a description of the controls and the function of the parts of your model.

Safe use of a power tool involves

1. the operator

2. the power tool

3. the use of the power tool.

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 machine when you are fatigued.

FSB-KM

English

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 machine.

Proper Clothing

WARNING

To reduce the risk of injury, the operator should wear proper protective apparel.

WARNING

The deflector provided with your KombiTool will not protect the operator from all foreign objects (gravel, glass, wire, etc.) thrown back by the rotating cutting attachment. Thrown objects may also ricochet and strike the operator.

WARNING

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). To reduce the risk of injury to your face STIHL recommends that you also wear a face shield or face screen over your goggles or protective glasses.

Power tool noise may damage your hearing. Wear sound barriers (ear plugs or ear mufflers) to protect your hearing. 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.

Always wear heavy duty work gloves (e.g. made of leather or other wear resistant material) when handling the cutting attachment.Heavy-duty, nonslip gloves improve your grip and help to protect your hands.

Clothing must be sturdy and snug-fitting, but allow complete freedom of movement. Wear long pants made of heavy material to help protect your legs. Do not wear shorts, sandals or go barefoot.

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 unit. 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.

For further instructions on proper clothing see the safety precautions in the instruction manual of the KombiEngine you are using.

THE POWER TOOL (KOMBIENGINE EQUIPPED WITH TRIMMER KOMBITOOL)

For illustrations and definitions of the power tool parts see the chapter on "Main Parts".

WARNING

Never modify this power tool in any way. Only attachments supplied by STIHL and expressly approved by STIHL for use with the specific STIHL KombiEngine are authorized. Although certain unauthorized attachments are

FSB-KM

English

002BA254 KN

useable with STIHL power tools, their use may, in fact, be extremely dangerous.

For the cutting attachments authorized by STIHL for your unit, see the chapter "Approved Combinations of Cutting Attachment, Deflector, Handle and Harness" in the instruction manual or the STIHL "Power Tools and Accessories" catalog.

If this tool 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 fuel system is tight (no leaks) and 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 POWER TOOL (KOMBIENGINE EQUIPPED WITH TRIMMER KOMBITOOL)

Transporting the Power Tool

WARNING

To reduce the risk of injury from loss of control and blade or line contact, never carry or transport your power tool with the cutting attachment moving.

It may be carried only in a horizontal position. Grip the shaft in a manner that the machine is balanced horizontally. Keep the hot muffler away from your body and the cutting attachment behind you.

WARNING

Always switch off the engine and make sure the working tool has stopped before putting a power tool down.

WARNING

When transporting it in a vehicle, properly secure it to prevent turnover, fuel spillage and damage to the unit.

Before Starting

WARNING

Always check your power tool for proper condition and operation before starting. Never attempt to modify the controls or safety devices.

Never use a power tool that is damaged or not properly maintained.

WARNING

Do not attach any cutting attachment to a unit without proper installation of all required parts. Failure to use the proper

parts may cause the head to fly off and seriously injure the operator or bystanders.

WARNING

The cutting attachment must be properly tightened and in safe operating condition. Inspect for loose parts (nuts, screws, etc.). Replace damaged heads before using the power tool.

Keep the handles clean and dry at all times; it is particularly important to keep them free of moisture, pitch, oil, fuel mix, grease or resin in order for you to maintain a firm grip and properly control your power tool.

WARNING

To reduce the risk of personal injury to the operator from blade or line contact and thrown objects, make sure your unit is equipped with the proper deflector, handle and harness for the type of cutting attachment being used (see chart in the chapter on "Approved Combinations of Cutting Attachment, Deflector, Handle and Harness.")

FSB-KM

English

002BA080 KN

As can be seen in that chart, some cutting attachments may require you to change your deflector, handle and / or harness.

Keep the deflector adjusted properly at all times (see chapters on "Mounting the Deflector" and "Mounting the Cutting Attachment" of your instruction manual).

Arrows on the deflector (as seen from the underside) show the correct direction of rotation of the cutting attachment. When viewed from above, however, the cutting attachment rotates counterclockwise.

Adjust harness (if you are wearing one) and hand grip to suit your size before starting work. The machine should be properly balanced as specified in your instruction manual for proper control and less fatigue in operation. To be better prepared in case of an emergency, practise releasing the unit from the harness as quickly as possible.

Starting Start the engine at least 10 feet (3 m)

from the fueling spot, outdoors only. For specific starting instructions, see the

appropriate section of your KombiEngine and KombiTool manuals. Place the power tool on firm ground or

other solid surface in an open area. Maintain good balance and secure footing.

WARNING

To reduce the risk of injury from blade or line contact, be absolutely sure that the cutting attachment is clear of you and all other obstructions and objects, including the ground, because when the engine starts at starting-throttle, engine speed will be fast enough for the clutch to engage and move the cutting attachment.

Once the engine has started, immediately blip the throttle trigger, which should release the starting throttle and allow the engine to slow down to idle.

With the engine running only at idle, attach the power tool to the spring hook of your harness if you are using one (see appropriate chapter of the instruction manual).

WARNING

Your power tool is a one-person machine. Do not allow other persons in the general work area, even when starting.

See also the safety precautions on Starting in the instruction manual of the KombiEngine.

During Operation Holding and Controlling the Power Tool

Always hold the unit firmly with both hands on the handles while you are working. Wrap your fingers and thumbs around the handles.

Your right hand should grip the rear handle. This also applies to left-handers.

WARNING

Never attempt to operate your power tool with one hand. Loss of control of the power tool resulting in serious or fatal injury may result. To reduce the risk of cut injuries, keep hands and feet away from the cutting attachment. Never touch a moving cutting attachment with your hand or any other part of your body.

WARNING

Do not overreach. Keep proper footing and balance at all times. Special care must be taken in slippery conditions (wet ground, snow) and in difficult, overgrown terrain. Watch for hidden obstacles such

FSB-KM

English

15m (50ft)

as tree stumps, roots and ditches to avoid stumbling. For better footing, clear away scrub and cuttings. Be extremely cautious when working on slopes or uneven ground.

WARNING

To reduce the risk of injury from loss of control, never work on a ladder or on any other insecure support. Never hold the cutting attachment above waist height.

Working Conditions Operate and start your power tool only

outdoors in a well-ventilated area. Operate it under good visibility and daylight conditions only. Work carefully.

WARNING

If the vegetation being cut or the surrounding ground is coated with a chemical substance (such as an active pesticide or herbicide), read and follow the instructions and warnings that accompany the substance at issue.

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. Control dust at the source where possible. Use good work practices, such as operating the unit so that the wind or operating process directs any dust raised by the power tool away from the operator. Follow the

FSB-KM

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.

Operating Instructions

WARNING

Do not operate your power tool using the starting throttle lock, as you do not have control of the engine speed.

In the event of an emergency, shut off the engine immediately – move the slide control / stop switch / momentary stop switch to 0 or STOP.

WARNING

The cutting attachment continues to rotate for a short period after the throttle trigger is released (flywheel effect.)

To reduce t he risk of eye and other injury always wear proper eye protection (see the chapter on "Proper Clothing") and ensure that bystanders are at least 50 feet (15 m) away. To reduce the risk of damage to property, also maintain this

distance from such objects as vehicles or windows. Even maintaining a minimum distance of 15 meters cannot exclude the potential danger. Any coworkers who must be in the restricted area should also wear goggles or protective glasses. Stop the engine immediately if you are approached.

Never use metal blades on this KombiTool. Only mowing heads are authorized.

WARNING

Inspect the work area: To reduce the risk of injury, remove stones, pieces of metal and other solid objects which could be thrown 15 meters or more by the cutting attachment or damage the cutting attachment and property (e.g. parked vehicles, windows).

WARNING

This power tool is normally to be used at ground level with the cutting attachment parallel to the ground. Use of a trimmer above ground level or with the cutting attachment perpendicular to the ground may increase the risk of injury, since the cutting attachment is more fully exposed and the power tool may be more difficult to control.

English

000BA019 KN

WARNING

During cutting, check the tightness and the condition of the cutting attachment at regular short intervals with the engine and attachment stopped. If the behavior of the attachment changes during use, stop the engine immediately, wait until the cutting attachment stops, and check the nut securing the attachment for tightness and the head for cracks, wear and damage.

WARNING

A loose head may vibrate, crack, break or come off the trimmer, which may result in serious or fatal injury. Make sure that the cutting attachment is properly tightened. Use the wrench supplied or one of sufficient length to obtain the proper torque. If the head loosens after being properly tightened, stop work immediately. The retaining nut may be worn or damaged and should be replaced. If the head continues to loosen, see your STIHL dealer. Never use a KombiEngine with a loose KombiTool.

WARNING

Replace a cracked, damaged or wornout head or a cracked, bent, warped, damaged, dull or worn out blade immediately, even if damage is limited to superficial cracks. Such attachments may shatter at high speed and cause serious or fatal injury.

WARNING

If the head, blade or deflector becomes clogged or stuck, always shut off the engine and make sure the cutting attachment has stopped before cleaning. Grass, weeds, etc. should be cleaned off the blade or from around the head at regular intervals.

WARNING

To reduce the risk of unintentional rotation of the cutting attachment and injury, always shut off the engine before replacing the cutting attachment. To reduce the risk of injury, always shut off the engine before adjusting the length of the nylon line on manually adjustable mowing heads.

USING THE CUTTING ATTACHMENTS

For an illustration of the various cutting attachments and instructions on proper mounting see the chapter on "Mounting the Cutting Attachment" in your instruction manual.

WARNING

To reduce the risk of severe or fatal injury from blade contact and / or loss of control, never attempt to use a metal blade on this trimmer.

Using the Mowing Heads

Do not use with mowing line longer than the intended length. With a properly mounted deflector, the built-in linelimiting blade will automatically adjust the line to its proper length.

Using the unit with an overly long nylon cutting line increases the load on the engine and reduces its operating speed. This causes the clutch to slip continuously and results in overheating and damage to important components (e.g. clutch, polymer housing components). Such damage could, among other things, cause the cutting attachment to rotate at idle.

Mowing heads are to be used only on trimmers equipped with a line-limiting blade in the deflector in order to keep the line at the proper length (see "Main Parts" chapter in your instruction manual).

FSB-KM

English

002BA073 KN

002BA074 KN

If the lawn edges are planted with trees or bordered by a fence etc., it is best to use a nylon line head. It achieves a "softer" cut with less risk of damaging tree bark etc. than polymer blades.

However, the polymer-bladed STIHL PolyCut produces a better cut if there are no plants along the edge of the lawn. Sharpening is not necessary, and worn polymer blades are easily replaced.

WARNING

To reduce the risk of serious injury, never use wire or metal-reinforced line or other material in place of the nylon cutting lines. Pieces of wire could break off and be thrown at high speed toward the operator or bystanders.

STIHL AutoCut mowing head Nylon cutting line advances

automatically when tapped against the ground (TapAction).

STIHL PolyCut mowing head 6-3 Uses nonrigid, pivoting polymer blades.

Do not continue using the PolyCut if one of the circular holes (1; arrow) becomes visible or if the projecting rim (2; arrow) has worn away. Install a new mowing head.

WARNING

If the wear limit marks are ignored, there is a risk of the cutting attachment shattering and flying parts injuring the operator or bystanders. To reduce the risk of accidents from shattered blades, avoid contact with stones, metal and similar solid objects. Check PolyCut blades for cracks at regular intervals. If a crack is found on one blade, always replace all blades.

MAINTENANCE, REPAIR AND STORING

WARNING

Always stop the engine and make sure that the cutting attachment is stopped before doing any maintenance or repair work or cleaning the power tool. Do not attempt any maintenance or repair work not described in your instruction manual. Have such work performed by your STIHL servicing dealer only.

WARNING

Use only identical STIHL replacement parts for maintenance and repair. Use of non-STIHL parts may cause serious or fatal injury.

Tighten all nuts, bolts and screws, except the carburetor adjustment screws, after each use.

Do not clean your machine with a pressure washer. The solid jet of water may damage parts of the machine.

Store the power tool in a dry and high or locked location out of reach of children.
