SAFETY INSTRUCTIONS
WARNING: Read all safety
warnings and 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.
WARNING: Risk of fire and
electric shock. Dry location use only. Do
not expose to rain. Risk of injury.
WORK AREA SAFETY
1. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
2. 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.
3. Keep children and bystanders away
while operating a power tool. Distractions
can cause you to lose control.
ELECTRICAL SAFETY
1. 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.
2. 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.
3. Do not expose power tools to rain or
wet conditions. Water entering a power tool
will increase the risk of electric shock.
4. Do not abuse the cord. Never use the
cord for carrying, pulling or unplugging the
power tool. Keep the cord away from heat,
oil, sharp edges or moving parts. Damaged
or entangled cords increase the risk of
electric shock.
5. 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.
6. If operating a power tool in a damp
location is unavoidable, use a ground fault
circuit interrupter (GFCI) protected supply.
Use of a GFCI reduces the risk of electric
shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing
and use common sense when operating a
power tool. Do not use the tool while tired
or under the influence of drugs, alcohol, or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
2. 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.
3. Prevent unintentional starting. Ensure
that 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 energizing power tools that have
the switch on invites accidents.

Page 5
SAFETY INSTRUCTIONS
4. 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.
5. Do not overreach. Keep proper footing
and balance at all times. This enables better
control of the power tool in unexpected
situations.
6. 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.
7. If devices are provided for the
connection of dust extraction and
collection facilities, ensure that these are
connected and properly used. Use of these
devices can reduce dust-related hazards.
USE AND CARE OF THE
POWER TOOLS
1. Do not force the power tool. Use the
correct power tool for your application. The
correct power tool will do the job better
and more safely at the rate for which it was
designed.
2. 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.
3. 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.
4. 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. 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.
6. Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.
7. Use the power tool, accessories,
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.
BATTERY TOOL USE
AND CARE
1. 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.
2. Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and
fire.
3. When the battery pack is not in use,
keep it away from other metal objects,
such as 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.
4. Under abusive conditions, liquid may
be ejected from the battery; avoid contact.
If contact accidentally occurs, flush with
water. If liquid contacts eyes, also seek
medical help. Liquid ejected from the battery
may cause irritation or burns.
