only with Skil lubricants: No. 80111 (8 oz.

Remove oil plug using the same wrench used
to remove the saw blade. The oil level should
never be below bottom threads in the housing.
When adding oil, fill until oil starts to run out of
oil hole at arrow on housing and replace oil
plug.
NOTE: If oil is extra dirty or thick, replace the
plug and run the saw for one minute to warm
up the oil. Then remove oil plug and turn saw
upside down, to remove all oil. Fill housing
with kerosene. Replace plug and run for one
minute to flush out the gear housing. Drain out
the kerosene and add fresh Skil lubricant.
With a new saw, change the oil after the first
ten hours of use.

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.
The brushes should be free from dust and dirt.
Brushes should be replaced when they have
worn down to 3/16" in length. The brushes
should slide freely in and out of the holders
without sticking.
To check brushes: Disconnect plug from
power source. Unscrew the brush caps on the

Only genuine Skil replacement brushes

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.
WARNING

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.

!
plastic parts. Some of these are: gasoline,
carbon tetrachloride, chlorinated cleaning
solvents, ammonia and household detergents
that contain ammonia.
Blades become dull even from cutting regular
lumber. If you find yourself forcing the saw
forward to cut instead of just guiding it
through the cut, chances are the blade is dull
or coated with wood pitch.
When cleaning gum and wood pitch from
blade, unplug the saw and remove the blade.
Remember, blades are designed to cut, so
handle carefully. Wipe the blade with
kerosene or similar solvent to remove the gum
and pitch. Unless you are experienced in
sharpening blades, we recommend you do
not try.
