4. Remove adjusting keys or switches before
turning the tool ON. A wrench or a key that is left
attached to a rotating part of the tool may result in
personal injury.
5. Do not overreach. Keep proper footing and
balance at all times. Proper footing and balance
enables better control of the tool in unexpected
situations.
6. Use safety equipment. Always wear eye pro-
tection. Dust mask, non-skid safety shoes, hard
hat, or hearing protection must be used for appro-
priate conditions.
7. Wear hearing protectors, ear plugs or muffs
when using tool. Noise level may affect hearing
with prolonged use.
Tool Use and Care
1. Use clamp 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.
2. 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.
3. Do not use tool if switch does not turn it ON or
OFF. Any tool that cannot be controlled with the
switch is dangerous and must be repaired.
4. Disconnect the plug from the power source
before making any adjustments, changing
accessories, or storing the tool. Such preven-
tive safety measures reduce the risk of starting the
tool accidentally.
5. Store idle tools out of the reach of children and
other untrained persons. Tools are dangerous in
the hands of untrained users.
6. Maintain tools with care. Keep cutting tools
sharp and clean. Properly maintained tools with
sharp cutting edges are less likely to bind and are
easier to control.
7. Check for misalignment or binding of moving
parts, breakage of parts, and any other condi-
tion that may affect the tool's operation. If dam-
aged, have the tool serviced before using. Many
accidents are caused by poorly maintained tools.
8. Use only accessories that are recommended by
the manufacturer for your model. Accessories
that may be suitable for one tool may become haz-
ardous when used on another tool.
9. Keep handles dry and clean; free from oil and
grease. Allows for better control of the tool.
Service
1. Tool service must be performed only by quali-
fied repair personnel. Service or maintenance
performed by unqualified repair personnel could
result in injury.
2. When servicing a tool, use only identical
replacement parts. Follow instructions in the
Maintenance Section of this manual. Use of
unauthorized parts or failure to follow mainte-
nance instructions may create a risk of electrical
shock or injury.
