1. SAFETY INSTRUCTIONS
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) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas inviteaccidents.
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 orfumes.
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 earthed or grounded surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is earthed orgrounded.
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 electricshock.
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 electricshock.
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 personalinjury.

4
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 invitesaccidents.
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 personalinjury.
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 and clothing away from
moving parts. Loose clothes, jewellery or long hair can be caught in movingparts.
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-relatedhazards.
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 fraction of asecond.
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 wasdesigned.
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 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 toolaccidentally.
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 powertool.
Power tools are dangerous 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 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 powertools.
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.

5
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.
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 unexpectedsituations.
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 batterypack.
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 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 afire.
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.
e) 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.
f) Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature
above 130 °C may cause explosion.
g) Follow all charging instructions and do not charge the battery pack or tool outside the
temperature range specified in the instructions. Charging improperly or at temperatures outside the
specified range may damage the battery and increase the risk offire.
6) Service
a) Have your power tool serviced by a qualified repair person using only identical replacementparts.
This will ensure that the safety of the power tool is maintained.
b) Never service damaged battery packs. Service of battery packs should only be performed by the
manufacturer or authorized service providers.
