Safety Precautions and Working Techniques

Because a KombiEngine equipped with a Bristle Brush or PowerSweep is a powerful 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) and deflector for the type of working tool you are using. Use only 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. 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 sweeping attachment. Thrown objects may result in serious or fatal injury to the operator or bystanders.

Use your KombiEngine equipped with the KW-KM PowerSweep only for moving wet materials, such as leaves or dirt, clearing snow and removing standing water from solid surfaces.

Use the KB-KM Bristle Brush only for sweeping areas and paths, including uneven and jointed surfaces, and natural stone paving.

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.

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

KB-KM, KW-KM

English

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 suitable deflector for your power tool will not protect the operator from all foreign objects (gravel, glass, wire, etc.) thrown back by the rotating 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).

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 power tool. 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 BRISTLE BRUSH OR POWERSWEEP)

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 model 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 BRISTLE BRUSH OR POWERSWEEP)

Transporting the Power Tool

WARNING

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

WARNING

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

KB-KM, KW-KM

English

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 use a power tool that is damaged or not properly maintained.

WARNING

Do not attach any sweeping attachment to a unit without proper installation of all required parts. Failure to use the proper parts may cause the working tool to fly off and seriously injure the operator or bystanders.

Position the gearbox so that the axle for sweeping and cleaning attachments is above the drive shaft.

WARNING

The sweeping attachment must be properly tightened and in safe operating condition. Inspect for loose parts (hitch pins, screws, etc.) and for damaged parts. Replace damaged parts 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.

Keep the deflector adjusted properly at all times (see chapter on "Assembling the Unit" of your instruction manual).

Adjust carrying harness 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, 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.

If you start the engine the working tool will rotate when the engine starts – this may set the sweeping attachment in motion back towards the operator.

WARNING

To reduce the risk of injury from loss of control, be absolutely sure that the working tool is clear of you and all other obstructions and objects, because when the engine starts at starting-throttle, engine speed will be fast enough for the clutch to engage and move the working 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).

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.

WARNING

To reduce the risk of injury from loss of control, hold and guide the machine at a shallow angle. If the machine is held at too steep an angle, it tends to push back toward the operator.

WARNING

Never work on steep slopes because of the risk of injury through loss of control of the power tool.

KB-KM Bristle Brush

KW-KM PowerSweep

WARNING

Never attempt to operate your power tool with one hand. Loss of control of the power tool may result in serious or fatal injury.

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. Be extremely cautious when working on slopes or uneven ground.

Operate the power tool only at a normal walking pace.

Working Conditions Start and operate your power tool only

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

WARNING

As soon as the engine is running, this product generates toxic exhaust fumes containing chemicals, such as unburned hydrocarbons (including benzene) and carbon monoxide, that are known to cause respiratory problems, cancer, birth defects, or other reproductive harm. Some of the gases (e.g. carbon monoxide) may be colorless and odorless. To reduce the risk of serious or fatal injury/illness from inhaling toxic fumes, never run the machine indoors or in poorly ventilated locations.

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

KB-KM, KW-KM

English

5m (16ft)

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.

WARNING

Never divert discharge of material toward bystanders nor allow anyone near the area of operation. Use care in directing discharge to avoid damage to surfaces, automobiles, and the like.

WARNING

Before you start work, examine the area for stones, glass, pieces of metal, rubbish or other solid objects. Such objects could be hurled aside by the sweeping tool and directly or indirectly strike the operator or bystanders. Such objects may also damage the sweeping tool.

WARNING

Static charges may build up when cleaning synthetic floors – risk of electric shock and accidents.

KB-KM, KW-KM

WARNING

To reduce the risk of a dust explosion, spray very dusty surfaces with water before sweeping. Always operate the power tool in such a way that the sweeping attachment cannot become jammed or blocked.

WARNING

To reduce the risk of injury, keep hands and feet away from the sweeping attachment.

WARNING

Use the sweeping attachments at ground level only. The risk of injury is increased if you use sweeping attachments above ground level because they are more exposed and the power tool is more difficult to control.

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.

See also the safety precautions in the instruction manual of your KombiEngine on the proper use of the slide control / stop switch / momentary stop switch.

WARNING

Never touch a rotating sweeping attachment with your hand or any part of your body. The sweeping attachment continues to rotate for a short period after the throttle trigger is released (flywheel effect).

If the sweeping attachment or deflector becomes clogged or stuck, always switch off the engine and make sure the sweeping attachment has stopped before cleaning. Dirt, grass, weeds, etc. should be cleaned off the sweeping attachment as necessary.

The rotating sweeping 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 16 feet (5 m) away. To reduce the risk of damage to property, also maintain this distance from such objects as vehicles or windows. Any coworkers who must be in the restricted area should also wear goggles or protective glasses.

Stop the engine immediately if you are approached.

WARNING

Du ring work , chec k the tight nes s and t he condition of the sweeping attachment at regular intervals with the engine and

English

attachment stopped. If the behavior of the sweeping attachment changes during use, stop the engine immediately and check the attachment for cracks, wear and damage. Replace cracked or damaged sweeping attachments immediately.

WARNING

Do not mount any sweeping attachment to a machine without proper installation of all required parts. Never use unauthorized parts to secure the sweeping attachments. Failure to use the proper parts may cause the attachments to fly off and seriously injure the operator or bystanders.

MAINTENANCE, REPAIR AND STORING

WARNING

Always stop the engine and make sure that the 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 KombiEngine and KombiTool instruction manuals. Have such work performed at your STIHL servicing dealer only.

WARNING

Check the condition of the attachment at regular short intervals. Loose parts might fly off and injure the operator or bystanders. To reduce the risk of injury, always replace sweeping attachments immediately and in pairs. Do not attempt to repair or continue using damaged or worn sweeping attachments.

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.
