4.7 Working
4.7.1 Sawing
WARNING
Always work within calling distance of others so that you can summon help in an emer- gency. Make sure that people are within earshot outside the working area.
In certain situations, the user may no longer be able to concentrate on their work. The user may lose control of the pole pruner, stumble or fall and be seriously injured. Keep calm and plan your work. If light and visibility are poor: Do not use the pole pruner. Use the pole pruner without assistance. Watch out for obstacles. Work standing on the ground and keep your balance. If you have to work at a height: Use a mobile elevating work platform or secure scaffolding. If you start feeling fatigue: Take a break.
The moving saw chain can cut the user. This may result in serious injury to the user. Do not touch the rotating saw chain. If the saw chain is blocked by an object: Switch off the pole pruner and remove the battery. before clearing the jam.
The moving saw chain warms up and expands. If the saw chain is not sufficiently lubricated and retensioned, the saw chain may jump off the guide bar or it may break.

The saw chain expands or contracts during cut- ting work. The saw chain tension changes as a result. Check the saw chain tension regularly during operation and readjust if necessary. Switch off the pole pruner and remove the bat-
tery.

Loosen the nut (1). Hold the guide bar nose up and turn the ten-
sioning screw (2) clockwise until the following points apply: The chain sag a’ in the center of the guide bar is 1 – 2 mm. The saw chain can still be pulled easily along the guide bar with two fingers. Hold the guide bar nose up and tighten down the nut (1) firmly. If the chain saga’ in the center of the guide
bar is not 1-2 mm: Readjust the saw chain ten- sion.
7.4 Filling Up with Saw Chain Oil
The saw chain oil lubricates and cools the rotat- ing chain. Switch off the pole pruner and remove the bat-
tery. Place the pole pruner on a level surface so
that the oil tank cap faces up. Use a damp cloth to clean the oil tank cap and
the area around it.
With a suitable tool, turn the oil tank cap coun- terclockwise until it can be removed.
Remove the oil tank cap. Fill up with saw chain oil, taking care not to
spill any oil and not to overfill the tank.

0000098569_001

Place the oil tank cap on the tank opening. With a suitable tool, turn the oil tank cap clock-
wise and tighten it down firmly. The oil tank is closed.

25 General Power Tool Safety Warnings
25.1 Introduction
This chapter reproduces the pre-formulated, gen- eral safety precautions specified in the IEC 62841 standard for hand-held motor-oper- ated electric tools.
STIHL is obliged to publish these texts.

The safety precautions and warnings on avoiding an electric shock given under “Electrical Safety” do not apply to STIHL cordless products.
WARNING
Read all safety warnings, instructions, illustra- tions and specifications provided with this power tool. Failure to follow all instructions lis- ted below may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference.
The term “electric power tool” in the safety warn- ings refers to mains- operated (corded) power tools or battery-operated (cordless) power tools.
25.2 Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
25.3 Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (groun- ded) power tools.Unmodified plugs and matching outlets will reduce risk of electric shock.
b) 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.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
d) 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 entan- gled cords increase the risk of electric shock.
e) 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.

46

0458-813-9621-B

General Power Tool Safety Warnings

f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
25.4 Personal safety
a) 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.
b) Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.
c) 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.
d) 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.
e) Do not overreach. Keep proper footing and balance at all times. This enables better con- trol of the power tool in unexpected situa- tions.
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
g) If devices are provided for the connection of dust extraction and collection facillities, ensure these are connected and properly used. Use of dust collection can reduce dustrelated hazards.
h) Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a frac- tion of a second.
25.5 Power tool use and care
a) Do not force the power tool. Use the correct power tool for your application. The correct
0458-813-9621-B

English
power tool will do the job better and safer at the rate for which it was designed.
b) 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 dan- gerous and must be repaired.
c) Disconnect the plug from the power source and/or remove the battery pack, if detacha- ble, from the power tool before making any adjustments, changing accessories, or stor- ing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
d) 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 dan- gerous in the hands of untrained users.
e) Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condi- tion that may affect the power tool’s opera- tion. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
g) 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 situa- tion.
h) Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
25.6 Battery tool use and care
