GENERAL MAINTENANCE
LUBRICATION
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, carton dust, etc.
All of the bearings in this tool are lubricated with a sufcient amount of high grade lubricant for the life of the unit under
normal operating conditions. Therefore, no further lubrications are required.
WARNING: Failure to unplug the saw could result
in accidental starting causing serious injury.
BRUSH REPLACEMENT (FIG. 34)
The saw has externally accessible brush assemblies that
should be periodically checked for wear.
• Unplug the saw.
• Remove the brush cap (A) with a screwdriver. The brush
assembly is spring loaded and will pop out when you
remove the brush cap.
• Remove the brush assembly (B).
• Check for wear. Replace both brushes when either has
less than 1/4 in. length of carbon remaining. Do not replace
one side without replacing the other.
• Reassemble using new brush assemblies. Make sure that
the curvature of the brush matches curvature of the motor
and that the brush moves freely in the brush tube.
• Make sure that the brush cap is oriented correctly (straight)
and replace.
• Tighten the brush cap securely. Do not over-tighten.
Some areas will require infrequent lubrication. You will need to apply:
• Automotive oil directly the slide bars.
• Light oil or pressurized light spray oil to the arm pivot shaft.
• Light oil or pressurized light spray oil to the torsion spring.
