Some areas will require infrequent lubrications. You will
need to apply:

Automotive oil directly to the slide bars.
 Light oil or a pressurized light spray oil to the arm pivot
shaft.
 Light oil or a pressurized light spray oil to the torsion
spring.
EXTENSION CORDS
The use of any extension cord will cause some loss of power.
To keep the loss to a minimum and to prevent tool overheat-
ing, use an extension cord that is heavy enough to carry the
current the tool will draw.
A wire gauge size (A.W.G.) of at least
14 is recommended for
an extension cord 25 feet or less in length. When working
outdoors, use an extension cord that is suitable for outdoor
use. The cord's jacket will be marked WA.
WARNING:
Keep extension cords away from the cutting area
and position the cord so that it will not get caught
on lumber, tools, etc., during cutting operation.
Failure to heed this warning may result in serious
personal injury.
CAUTION:
Check extension cords before each use. If dam-
aged, replace immediately. Never use tool with a
damaged cord since touching the damaged area
could cause electrical shock resulting in serious
injury.
BRUSH REPLACEMENT
See Figure 37.
The saw has externally accessible brush assemblies that
should be periodically checked for wear.
Proceed as follows when replacement is required:

Unplug the saw.
WARNING:
Failure to unplug the saw could result in accidental
starting causing serious injury.
 Remove brush cap with a screwdriver. Brush assembly is
spring loaded and will pop out when you remove brush
cap.
 Remove brush assembly.
 Check for wear. Replace both brushes when either has
less than 1/4 in. length of carbon remaining. Do not re-
place one side without replacing the other.
 Reassemble using new brush assemblies. Make sure
curvature of brush matches curvature of motor and that
brush moves freely in brush tube.
 Make sure brush cap is oriented correctly (straight) and
replace.
 Tighten brush cap securely. Do not overtighten.
