firmly, squeeze trigger and slowly push the
saw forward. To make a hole, cut from inside
the circle; To make wheels or discs, cut from
the outside.

Cutting Tip: Cut slowly so the blade will stay
straight in the cut. Place small wedges in the
cut as shown in Fig. 13, to keep the inner
circle from spreading when near the end of the
cut.

Service

Preventive maintenance
performed by unauth-

orized personnel may result in misplacing
of internal wires and components which
could cause serious hazard.

We

recommend that all tool service be performed
by a Skil Factory Service Center or Autho-
rized Skil Service Station.

TOOL LUBRICATION

Your Skil tool has been properly lubricated
and is ready to use. It is recommended that
tools with gears be regreased with a special
gear lubricant at every brush change.

CARBON BRUSHES

The brushes and commutator in your tool
have been engineered for many hours of
dependable service. To maintain peak
efficiency of the motor, we recommend every
two to six months the brushes be examined.
Only genuine Skil replacement brushes
specially designed for your tool should be
used.

BEARINGS

After about 300-400 hours of operation, or at
every second brush change, the bearings

should be replaced at Skil Factory Service
Center or Authorized Skil Service Station.
Bearings which become noisy (due to heavy
load or very abrasive material cutting) should
be replaced at once to avoid overheating or
motor failure.

Cleaning

To avoid accidents always
disconnect the tool from

the power supply before cleaning or
performing any maintenance.
The tool may
be cleaned most effectively with compressed
dry air.

Always wear safety goggles when

cleaning tools with compressed air.

Ventilation openings and switch levers must
be kept clean and free of foreign matter. Do
not attempt to clean by inserting pointed
objects through openings.

Certain cleaning agents
and solvents damage

plastic parts. Some of these are: gasoline,
carbon tetrachloride, chlorinated cleaning
solvents, ammonia and household
detergents that contain ammonia.
