General Power Tool Safety Warnings

WARNING Read all safety warnings and all

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

1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.

2. Do not operate power tools in explosive

atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools

create sparks which may ignite the dust or fumes.

3. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

4. 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.

5. Avoid body contact with earthed or grounded

surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of

electric shock if your body is earthed or grounded.

GEA006-2

6. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

7. 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.

8. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

9. If operating a power tool in a damp location is

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

GFCI reduces the risk of electric shock.

Personal safety

10. 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.

11. 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.

12. 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 energising power tools that have the switch on invites accidents.

13. 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.

14. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

15. Dress properly. Do not wear loose clothing or

jewellery. Keep your hair, clothing, and gloves away from moving parts. Loose clothes,

jewellery or long hair can be caught in moving parts.

16. 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

17. Do not force the power tool. Use the correct power tool for your application. The correct

power tool will do the job better and safer at the rate for which it was designed.

18. 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.

19. 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 reduce the risk of starting the power tool accidentally.

20. 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.

21.

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.

22. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

23. 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 the

power tool for operations different from those intended could result in a hazardous situation.

Battery tool use and care

24. Recharge only with the charger specified by the manufacturer. A charger that is suitable for

one type of battery pack may create a risk of fire when used with another battery pack.

25. Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.

26. When battery pack is not in use, keep it away

from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery

terminals together may cause burns or a fire.

27. Under abusive conditions, liquid may be

ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery

may cause irritation or burns.

Service

28. 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.

29. Follow instruction for lubricating and

changing accessories.

30. Keep handles dry, clean and free from oil and

grease.

GEB118-1

Cordless Chain saw safety warnings:

1. 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.

2. When holding with both hands, 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.

3. Hold the power tool by insulated gripping

surfaces only, because the saw chain may contact hidden wiring. Saw chains contacting a

"live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.

4. Wear safety glasses and hearing protection.

Further protective equipment for head, hands, legs and feet is recommended. Adequate

protective clothing will reduce personal injury by flying debris or accidental contact with the saw chain.

5. Always keep proper footing. Slippery or unstable surfaces may cause a loss of balance or control of the chain saw.

6. 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.

7. Use extreme caution when cutting brush and saplings. The slender material may catch the saw chain and be whipped toward you or pull you off balance.

8. 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.

9. Follow instructions for lubricating, chain tensioning and changing accessories. Improperly tensioned or lubricated chain may either break or increase the chance for kickback.

10. Keep handles dry, clean, and free from oil and grease. Greasy, oily handles are slippery causing loss of control.

11. 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.

12. 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:

− 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.

014673

− 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. Incorrect

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.

13. Before starting work, check that the chain saw is in proper working order and that its condition complies with the safety regulations. Check in particular that:

• The chain brake is working properly;

• The run-down brake is working properly;

• The bar and the sprocket cover are fitted

correctly;

• The chain has been sharpened and tensioned

in accordance with the regulations;

14. Do not start the chain saw with the chain cover being installed on it. Starting the chain saw with the chain cover being installed on it may cause the chain cover to thrown out forward resulting in personal injury and damage to objects around the operator.

Top handle chainsaw specific safety warnings

1. This chain saw is designed especially for tree care and surgery. The chain saw is intended to be used by properly trained persons only. Observe all instructions, procedures and recommendations from the relevant professional organization. Otherwise fatal accidents may occur. It is recommend that always using a rising platform (cherry picker, lift) for sawing in trees. Rappelling techniques are extremely dangerous and require special training. The operators must be trained to become familiar with safety equipment usage and climbing techniques. Always use the appropriate belts, ropes and carabiners when working in trees. Always use restraining equipment for both the operator and the saw.

2. Perform cleaning and maintenance before storage in accordance with the instruction manual.

3. Ensure safe positioning of the chain saw during car transportation to avoid fuel or chain oil leakage, damage to the tool and personal injury.

4. Regularly check the functionality of chain brake.

5. Do not fill the chain oil near fire. Never smoke when you fill the chain oil.

6. National regulation may restrict the use of the chain saw.

7. If the equipment gets heavy impact or fall, check the condition before continuing work. Check the controls and safety devices for malfunction. If there is any damage or doubt, ask our authorized service center for the inspection and repair.

8. Always activate the chain brake before starting the chain saw.

9. Hold the saw firmly in place to avoid skating (skid movement) or bouncing of the saw when starting a cut.

10. At the end of the cut, be careful to keep your balance due to the “drop”.

11. Take into account the direction and speed of the wind. Avoid sawdust and chain oil mist.

Protective equipment

1. In order to avoid head, eye, hand or foot injuries as well as to protect your hearing the following protective equipment must be used during operation of the chain saw:

− The kind of clothing should be appropriate, i. e. it should be tight-fitting but not be a hindrance. Do not wear jewelry or clothing which could become entangled with bushes or shrubs. If you have long hair, always wear a hairnet!

− It is necessary to wear a protective helmet whenever working with the chain saw. The protective helmet is to be checked in regular intervals for damage and is to be replaced after 5 years at the latest. Use only approved protective helmets.

− The face shield of the protective helmet (or the goggles) protects against sawdust and wood chips. During operation of the chain saw always wear a goggle or a face shield to prevent eye injuries.

− Wear adequate noise protection equipment. (ear muffs, ear plugs, etc.)

− The protective jacket consists of 22 layers of nylon and protects the operator against cuts. It is always to be worn when working from elevated platforms (cherry pickers, lifts), from platforms mounted on ladders or when climbing with ropes.

− The protective brace and bib overall is made of a nylon fabric with 22 layers and protects against cuts. We strongly recommend its use.

− Protective gloves made of thick leather are part of the prescribed equipment and must always be worn during operation of the chain saw.
