MAINTENANCE

BRUSH REPLACEMENT

See Figure 50.

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 replace 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.

MOTOR BELT TENSION

See Figure 51.

The motor belt tension was adjusted at the factory but should still be checked periodically.

To check belt tension:

Using a phillips screwdriver, remove the screws holding the belt cover. Lift off the cover.

Check belt tension by squeezing the belt. Using light pressure, the belt should deflect approximately 1/4 in.

To adjust belt tension:

Loosen, but don’t remove, the six motor mount screws.

Increase the belt tension by turning the adjusting socket head set screw clockwise. Decrease the belt tension by turning the set screw counterclockwise.

NOTE: Excessive belt tension will cause the motor to fail prematurely.

Securely tighten the six motor mount screws.

Replace the belt cover and tighten securely using screws.
