CHECKING MOTOR BELT TENSION AND REPLACING THE BELT

See Figure 45.

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 on the right side of the saw arm. Lift off the cover.

The belt tension is correct when the tension mark on the spring bracket is between “C” and “D” (see figure 54).

To adjust belt tension:

Using a phillips screwdriver, remove the screws holding the drive pulley cover on the left side of the saw arm. Lift off the cover.

Remove the screws holding the carrying handle on the saw arm, then remove the carrying handle.

Loosen, but don’t remove, the 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.

Once the tension mark on the spring bracket is between “C” and “D”, securely tighten the motor mount screws.

Replace the belt and drive pulley covers and tighten securely using screws.

NOTE: Cord must never touch the belt.

To replace the belt:
