Maintenance Instructions

WARNING

Always be sure that the tool is switched OFF and

unplugged before changing blade or servicing saw.

Keep the tool cleaned. Remove accumulated dust from

working parts.

Make sure that the tool operates properly.

Periodically check screws and bolts for tightness.

Replacing Carbon Brushes

The carbon brushes furnished will last approximately 50

hours of running time or 10,000 ON/OFF cycles. Replace

both carbon brushes when either has less than

″ length

of carbon remaining.

1. To inspect or replace brushes, first unplug the

machine. Then remove the black plastic cap on the

side of the motor.

This cap spring-loaded by the brush as-

sembly.

Then pull out the brush. Repeat for the other side.

2. To reassemble reverse the procedure. The ears on

the metal end of the brush assembly go in the same

hole the carbon part fits into. Tighten the cap snugly

but do not overtighten.

NOTE! To reinstall the same brushes, first make sure

the brushes go back in the way they came out.

Otherwise, a break-in period will occur that will

reduce motor performance and increased brush

wear.

Lubrication

Power Head Pivot (Figure 9)

Light machine oil or aerosol will penetrate from ends

and junction points near spring and pivot pin.

Central Pivot of Guard (Figure 9)

Use light household oil (sewing machine oil) on metal-to-

metal guard contact areas as required for smooth, quiet

operation. Reduce the risk of excess oil, to which cutting

debris will cling and a fire hazard from sparks could be

caused.

Vise (Figure 9)

Use light machine oil on rotating and sliding parts of the

vise.

• Rotary part of vise

• Slide way of vise

NOTE! All the motor bearings in this tool are lubricated

with a sufficient amount of high-grade lubricant for

the life of the unit under normal operating condi-

tions, therefore, no further lubrication is required.

NOTE! It is recommended that, at least once a year,

you take the tool to an Authorized Service Center

for a thorough cleaning and lubrication.
