Wear Eye Protection.
Wear Hearing Protection.
Wear Dust Mask.
Power tools can vibrate in use.
Keep body stance balanced and firm. Do not overreach when operating this
tool.
IMPORTANT SAFETY RULES
When using power tools, always prevent exposure and breathing of harmful
dust and particles.
WARNING: Some dust created by power sanding, sawing, grinding, drilling and
other construction activities contains chemicals known to the State of California to
cause cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks and cement and other masonry products, and
arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of
work. To reduce your exposure to these chemicals: work in a well ventilated area,
and work with approved safety equipment, such as dust masks that are specially
designed to filter out microscopic particles.
WARNING: Handling the power cord on corded products may expose you to lead, a
chemical known to the State of California to cause cancer and birth defects or other
reproductive harm. Wash hands after handling.
WORK AREA
DANGER

-4
Keep work area clean and well lit. Cluttered and 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
a. 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.
b. Do not expose power tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock
c. 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.
d. 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.
e. 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.
f. NOTE The term “residual current device (RCD)” can be replaced by the term
“ground fault circuit interrupter (GFCI)” or “earth leakage circuit breaker
(ELCB)”.
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 safety equipment. Always wear eye protection. Safety 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 these devices
can reduce dust-related 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 fraction of a second.
TOOL USE AND CARE
a. Use clamps or other practical way to secure and support the workpiece to a
stable platform. Holding the work by hand or against your body is unstable and
may lead to loss of control.
b. Do not force tool. Use the correct tool for your application. The correct tool
will do the job better and safer at the rate for which it is designed.
c. Do not use tool if switch does not turn it on or off. A tool that cannot be
controlled with the switch is dangerous and must be repaired.
d. Disconnect battery pack from tool or place the switch in the locked or off
position before making any adjustments, changing accessories, or storing the
tool. Such preventive safety measures reduce the risk of starting the tool
accidentally.
e. Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.
f. 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.
g. Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
WARNING

h. 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.
i. 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.
j. 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 sparks, burns, or a fire.
k. Maintain tools with care. Keep cutting tools sharp and clean. Properly
maintained tools with sharp cutting edge are less likely to bind and are easier to
control.
l. Check for misalignment or binding of moving parts, breakage of parts, and
any other condition that may affect the tool's operation. If damaged, have
the tool serviced before using. Many accidents are caused by poorly maintained
tools.
