1 Safety Instructions
1.1 General Power Tool Safety Warnings
WARNING: Read all safety warnings, instructions, illustrations
and specifications provided with this power tool.
Failure to follow all
instructions listed below 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.
1.1.1 Work Area Safety
•
Keep work area clean and well lit.
Cluttered or dark areas invite
accidents.
•
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.
•
Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
1.1.2 Electrical Safety
•
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.
•
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.
•
Do not operate the machine in rain or wet conditions.
Water entering
the machine may increase the risk of electric shock or malfunction that
could result in personal injury.
•
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.
•
When operating a power tool outdoors, use an extension cord
suitable for outdoor use.
Use of a cord suitable for outdoor use reduces

may result in personal injury.
•
Do not overreach. Keep proper footing and balance at all times.
This
enables better control of the power tool in unexpected situations.
•
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.
•
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.
•
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 fraction of a second.
1.1.4 Power Tool Use and Care
•
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.
•
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.
•
Disconnect the plug from the power source and/or remove the
battery pack, if detachable, 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.
•
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.
5
EN
•
Maintain power tools and accessories. 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.
•
Keep cutting tools sharp and clean.
Properly maintained cutting tools
with sharp cutting edges are less likely to bind and are easier to control.
•
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.

and grease.
Slippery handles and grasping surfaces do not allow for safe
handling and control of the tool in unexpected situations.
1.1.5 Battery Tool Use and Care
•
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.
•
Use power tools only with specifically designated battery packs.
Use of any other battery packs may create a risk of injury and fire.
•
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.
•
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.
•
Do not use a battery pack or tool that is damaged or modified.
Damaged or modified batteries may exhibit unpredictable behaviour
resulting in fire, explosion or risk of injury.

•
Use extreme caution when cutting brush and saplings.
The slender
material may catch the blade and be whipped toward you or pull you off
balance.
•
Maintain control of the machine and do not touch cutters, lines or
blades and other hazardous moving parts while they are still in motion.
This reduces the risk of injury from moving parts.
•
Carry the machine with the machine switched off and away from
your body.
Proper handling of the machine will reduce the likelihood of
accidental contact with a moving cutter, line or blade.
•
Only use replacement cutters, lines, cutting heads and blades
specified by the manufacturer.
