GENERAL SAFETY INSTRUCTIONS
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 mainsoperated (corded) power tool or battery-operated (cordless) power tool.
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.
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 expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
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 the risk of electric shock.
If operating a power tool in a damp location is unavoidable, use an earth leakage circuit
breaker. Use of an earth leakage circuit breaker reduces the risk of electric shock.
PERSONAL SAFETY
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.
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.
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.
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.
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 jewelry. Keep your hair, clothing and
gloves away from moving parts. Loose clothes, jewelry 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.
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 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.
Store idle power tools out of the reach of children and do not allow p ersons unfamiliar
with the power tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained users.
Maintainpowertools . 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.
