MAINTENANCE & SERVICE
REPLACING BELT & ADJUSTING BELT
TENSION
If the drive belt needs to be replaced or
properly tensioned, follow these instructions;
- Make sure that the power cord is removed
from the main power supply.
- Push down on the saw arm and pull and turn
the saw head release knob to lock the saw arm
in the down position.
- Remove the drive belt cover by removing the
3 pan head screws.
- To release the belt tension, first loosen the 6
pan head screws inside the belt housing to
allow the motor to move position. Then
unscrew the belt tension set screw to release
the belt tension.
- Remove the used drive belt by hand.
- Reposition new drive belt making sure the
belt is properly centered on both pulleys.
- Tighten the belt tension set screw until you
obtain a 1/2" center deflection of the belt by
applying pressure with your fingers.
- Once the belt is properly tensioned, retighten
the 6 pan head screws.
- Reposition the belt cover and secure it into
place using the same 3 pan head screws
removed previously.
Cleaning
After use, wipe off chips and dust adhering to
the tool with cloth or the like. Keep the blade
guards and covers clean. Lubricate the sliding
portions with machine oil to prevent rust.
To maintain product SAFETY and RELIABILITY,
repairs, any other maintenance or adjustment
should be performed by your nearest
authorized service center.
NOTE
: All the ball bearings are sealed and
lubricated for life and will require no
maintenance.
REPLACING CARBON BRUSHES
Remove and check the carbon brushes regularly
(normally after 50 hours of use). The carbon
brushes are installed inside the motor housing.
Using a screwdriver, remove the 2 pan head
screws that hold the motor housing cap in place.
Once the motor housing cap is removed, to
release the carbon brush from the holder, lower
the retaining spring. Disconnect the carbon
brush wire from the terminal, remove the
carbon brush from the motor housing and
inspect it. Repeat this step for the second
carbon brush. Carbon brushes need to be
replaced once they wear down to the limit mark.
Keep the carbon brushes clean and free to slip in
the holders.
If they have worn down to the limit mark,
purchase a set of identical replacement carbon
brushes (both carbon brushes should be
replaced at the same time). Insert new carbon
brushes into the holders, connect them to the
terminals, reposition the retaining spring and
reinstall the motor housing cap using the 2 pan
head screws
