before turning the tool “ON”. A wrench that is
left attached to a rotating part of the tool may
result in personal injury.
7. Do no overreach. Keep proper footing
and balance at all times. Proper footing and
balance enables better control of the tool in
unexpected situations.
8. Always secure your work. Use clamps or a
vise to hold work when practical. It is safer
than using your hand and frees both hands to
operate tool.
9. Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety shoes,
hard hat or hearing protection must be used
for appropriate conditions.
10. Do not use on a ladder or unstable
support. Stable footing on a solid surface
enables better control of the tool in
unexpected situations.
TOOL USE AND CARE SAFETY
1. Always use clamps or other practical ways
to secure and support the work piece 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 the tool. Use the correct tool
and blade for your application. The correct tool
and blade will do the job better and safer at
the rate for which it is designed.
3. Do not use the 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.

DESCRIPTION / REASON SERVICE
INTERVAL
ITEM
Through normal operation of your air compressor,
conndensation water will accumulate in the tank. To prevent
corrosion of the tank from the inside, condensation must be
drained at the end of every workday. Be sure to wear protective
goggles. Relieve the air pressure in the system then open the
tank drain on the bottom of the tank to drain. Under cold
conditions it is especially important to drain the tank after each
use to reduce the chance of problems resulting from the freezing
of condensation water.
