GENERAL POWER TOOL
SAFETY WARNINGS
WARNING:
Read all safety
warnings, instructions, illustrations and
specications 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.
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
ammable 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 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 an 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 a power tool while
you are tired or under the inuence 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
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.
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.
Page 5
SAFETY INSTRUCTIONS
6. Dress properly. Do not wear loose
clothing or jewelry. Keep your hair and
clothing 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 these are
connected and properly used. Use of dust
collection can reduce dust-related hazards.
8. 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.
POWER TOOL USE AND CARE
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
safer 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 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 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 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.
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
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.
8. 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.
BATTERY TOOL USE
AND CARE
1. Recharge only with the charger
specied 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 specically
designated battery packs. Use of any other
battery packs may create a risk of injury and
fire.
3. 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 a fire.
4. Under abusive conditions, liquid may
be ejected from the battery; avoid contact.
If contact accidentally occurs, ush with
water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the
battery may cause irritation or burns.
5. Do not use a battery pack or tool that
is damaged or modied. Damaged or
modified batteries may exhibit unpredictable
behavior resulting in fire, explosion or risk of
injury.
Page 6
SAFETY INSTRUCTIONS
6. Do not expose a battery pack or tool
