Safety Precautions and Working Techniques

Because a KombiEngine equipped with a bed redefiner KombiTool is a high-speed 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.

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 (if applicable), skirt and deflector. Use only cutting attachments that are specifically authorized by STIHL for use on your KombiEngine model.

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 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 and may cause blades to crack, chip or break. Thrown objects, including broken blades, may result in serious or fatal injury to the operator or bystanders.

Do not use the bed redefiner on hard grounds or for wet soil.

Use your KombiEngine equipped with the bed redefiner KombiTool only for redefining existing flower bed edges.

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 can not use it.

Most of these safety precautions and warnings apply to the use of all STIHL bed redefiners. 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.

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.

The deflector provided with your power tool 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 Z 87.1 (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 gloves when handling the machine and metal blades. 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 BED REDEFINER KOMBITOOL)

For illustrations and definitions of the KombiTool 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 useable with STIHL power tools, their use may, in fact, be extremely dangerous.

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 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 BED REDEFINER KOMBITOOL)

Transporting the Power Tool

WARNING

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

WARNING

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

It may be carried only in a horizontal position. Grip the shaft in a manner that the machine is balanced horizontally.

FBD-KM

English

9924BA001 KN

Keep the hot muffler away from your body and the cutting attachment behind you.

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.

WARNING

Never operate your power tool if it is damaged, improperly adjusted or maintained, or not completely or securely assembled.

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 blade to fly off and seriously injure the operator or bystanders.

WARNING

The deflector and the cutting attachment must be properly tightened and in safe operating condition. Inspect for loose parts (nuts, screws, etc.) and for cracked, bent, warped or damaged blades and parts. Replace a damaged deflector or damaged blades 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 contact and thrown objects, make sure your unit is equipped with the proper deflector, skirt, handle and harness (if applicable).

An arrow on the deflector shows the correct direction of rotation of the cutting blade.

The arrow on the deflector must always face away from you, so that cuttings and other debris will be diverted away from the machine and your position (see chapter "Using the Unit").

Adjust carrying harness and loop handle 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, practice releasing the unit from the harness as quickly as possible.

Starting

WARNING

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 loss of control, be absolutely sure that the cutting tool 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 blade on the cutting tool.

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 this manual).

FBD-KM

English

002BA547 KN

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

WARNING

Pull your powertool. Never push it forward. Always hold the unit on the left hand side of your body and with the cutting tool behind at a safe distance. See the section on "Using the Unit".

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 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.

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 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, switch off the engine immediately – move the slide control / stop switch / momentary stop switch to 0 or STOP (depending on the used KombiEngine).

See section of your KombiEngine instruction manual on the proper use of the slide control / stop switch / momentary stop switch (depending on the used KombiEngine).

English

15 m (50 ft)

WARNING

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

WARNING

The rotating cutting attachment may fling foreign objects directly or by ricochet a great distance.

To reduce the 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.

FBD-KM

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

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 screw securing the attachment for tightness and the blade for cracks, wear and damage.

WARNING

A loose blade may vibrate, crack, break or come off the bed redefiner, 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 blade loosens after being properly tightened, stop work immediately. The retaining screw may be worn or damaged and should be replaced. If the blade continues to loosen, see your STIHL dealer. Never use a KombiEngine with a loose KombiTool.

WARNING

Replace a cracked, bent, warped, damaged 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

When using your bed redefiner, avoid cutting close to fences, sides of buildings, tree trunks, stones or other such objects that could cause the power tool to kick out or could cause damage to the blade.

WARNING

If the 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 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.
