Safety Precautions and Working Techniques

Because a KombiEngine equipped with a soil cultivator 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 and harness for the type of working tool you are using. Use only working tools 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 injure 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 soil cultivating 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.

STIHL does not recommend the use of non-elastic blades when working in stony areas.

Use your KombiEngine equipped with the soil cultivator KombiTool only for rejuvenation of flower beds and plantings, and for mixing soil-improving additives into the soil.

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 soil cultivators. 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.

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.

The deflector provided with your power tool will not protect the operator from all foreign objects (stones, glass, wire, etc.) thrown back by the rotating working tool. 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 soil cultivating 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 SOIL CULTIVATOR KOMBITOOL)

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 soil cultivating 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 soil cultivating attachment to a unit without proper installation of all required parts. Failure

to use the proper parts may cause the blades to fly off and seriously injure the operator or bystanders.

WARNING

The soil cultivating 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. Replace 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.

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

Adjust harness and hand grip to suit your size before starting work. 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.

English

WARNING

To reduce the risk of injury from loss of control, do not attempt to "drop start" your power tool.

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, 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 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 (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.

Your right hand should grip the control handle at the rear, and your left hand should grip the loop handle. This also applies to left-handers.

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 soil cultivating attachment above waist height.

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 soil cultivating attachment. Never touch a moving working tool 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 soil being worked on 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.

DANGER

Your power tool is not insulated against electric shock. To reduce the risk of electrocution, ensure that there are no buried power cables that may be carrying electric current that could come into contact with the working tool. Damaging such cables with the tool can cause electric shocks with serious or fatal consequences.

Information on the routing of cables can be obtained from public utilities and such service providers as "Miss Utility" or "One Call."

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.

WARNING

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

To reduce the risk of eye and other injury always wear proper eye protection (see section 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

Before you start work, examine the area for stones, glass, fence wire, metal, trash or other solid objects. The soil cultivating attachment could throw objects of this kind.

WARNING

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

WARNING

Avoid cutting close to fences, sides of buildings, tree trunks, stones or similar obstacles which could damage the blade or lead to loss of control of the unit. Be aware of a higher risk of ricochets in such conditions. Flying objects or

English

damaged blades may cause serious or fatal injuries to the operator and bystanders. Avoid the roots of trees! Large roots may jam the blades and damage the machine. The tree may also be damaged if its roots are severed.

WARNING

If the working tool or deflector is blocked or covered, always switch off the engine and ensure that the tool has come to a standstill before starting to clean it. Grass, weeds, etc. should be cleaned off the tool at regular intervals.

WARNING

To reduce the risk of unintentional rotation of the working tool and injury, always shut off the engine and remove the spark plug boot before replacing the soil cultivating attachment.

WARNING

The gearbox becomes hot during operation. To reduce the risk of burn injury, do not touch the gear housing when it is hot.

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

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

Wear gloves when handling or performing maintenance on blades.

WARNING

Never repair damaged attachments by welding, straightening or modifying the shape. This may cause parts of the attachment to come off and result in serious or fatal injuries.

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

●Loosening soil around plants

Only loosen the surface soil around plants. Avoid going too deep as this could damage the shallow roots of some plants.

To avoid any damage to the cultivator or trees, be wary not to catch the blades on the large roots of trees.

●Working in soil improvers

The cultivator can be used for mulching with loam, compost, leaves, other organic material or fertilizers.

Prepare the area by removing all old roots, the remains of large plants and hard objects (stones etc.). Spread the mulch evenly on the ground.

Work in the mulch with a circular or back and forth motion.

Finish off by leveling the area with a rake.

●Trenching or furrowing

Walk slowly backward and pull the cultivator to create the furrow required. Repeat as necessary to obtain deeper furrows.

Cleaning the rotor blades

Parts of plants, e.g. roots, can become tightly wrapped around or between the rotor blades during operation. To clean the rotor blades:

• Wear work gloves.
  – Pull the hitch pins out of the axle.
  – Pull the rotor blades off the shaft.
• Remove pieces of roots, plants and soil.
