MAINTENANCE
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.
CHANGING THE BATTERIES
See Figure 52.
Unplug the saw.
Rotate and hold lower blade guard up.
Using the hex key (1/16 in.) provided, loosen and remove the screw from the battery cover then separate the cover from the laser guide.
Lower the blade guard.
Remove the three button cell batteries.
NOTE: Replace the batteries with button cell batteries that have a rating of 1.5 volt and 100 mAh (milliampere hour) minimum (number 76 series or equivalent).
When replacing the batteries, the laser guide should be thoroughly cleaned. Use a soft paintbrush, or similar device, to remove all sawdust and debris.
