WARNING:
When servicing, use only identical replacement
parts. Use of any other part may create a hazard
or cause product damage.
WARNING:
Always wear safety goggles or safety glasses with
side shields during power tool operation or when
blowing dust. If operation is dusty, also wear a
dust mask.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, carbon dust, etc.
WARNING:
Do not at any time let brake fluids, gasoline, pe-
troleum-based products, penetrating oils, etc.,
come in contact with plastic parts. They contain
chemicals that can damage, weaken, or destroy
plastic.
LUBRICATION
All of the bearings in this tool are lubricated with a sufficient
amount of high grade lubricant for the life of the unit under
normal operating conditions. Therefore, no further lubrica-
tion is required.
WARNING:
To ensure safety and reliability, all repairs should
be performed by a qualified service technician at
an authorized service center to avoid risk of per-
sonal injury.
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.
BRUSH REPLACEMENT
See Figure 38.
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.
