Tool Lubrication
Your Skilsaw tool has been properly lubricated
and is ready to use. However it is recommend-
ed that the gears be relubricated only with Skil
lubricants: No. 80111 (8 oz. tube).
Always check the oil level before using the
saw. To check and add oil: Remove plug from
power source and place the saw's foot on a
horizontal surface with tool set to maximum
depth of cut. Remove oil plug / lock button as-
sembly. The oil level should never be below
bottom threads in the housing. When adding
oil, fill until oil reaches bottom threads of the
housing. Do not over fill. Replace oil plug/lock
button assembly when finished (Fig. 13).

NOTE: If oil is dirty or thick, replace the oil
plug/lock button assembly and run the saw for
one minute to warm up the oil. Then remove

Maintenance
lubricant. With a new saw, change the oil after
the first ten hours of use.
The brushes and commutator in your tool have
been engineered for many hours of depend-
able service. To maintain peak ef ficiency 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 pow-
er source. Unscrew the brush caps on the mo-
tor housing and lift out the brushes; note which
way they face, so that the brushes can be re-
turned to their original position. To replace the
blade side brush the tool needs to be set to
minimum depth of cut. Clean the brush holder
openings with com pressed air or a clean cloth
and replace the brushes and caps.
Only genuine Skilsaw replacement brushes
specially designed for your tool should be
used.
Bearings which become noisy (due to heavy
load or very abrasive material cut ting) should
be replaced at once to avoid overheating or
