Safety
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.
1) 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.
2) 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 (grounded) power tools. Unmodified plugs and matching
outlets will reduce risk of electric shock.
b) Avoid body contact with 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 entangled 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.
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.

English
3) 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 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
control of thepower tool in unexpected situations.
f) 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.
g) 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.
4) Power tool use and care
a) 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.
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 dangerous and must be repaired.
c) 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.
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
dangerous in thehands of untrained users.
e) 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.
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 situation.

5) Battery tool use and care
a) 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.
b) Use power tools only with specifically designated battery packs. Use of any other
battery packs may create arisk of injury and fire.
c) When the 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.
d) 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.

- Trees, bushes, etc. thetrimmer
line can damage sensitive bark
and fence posts.
- Walls, curbstones, etc.
