REPLACING BELTS AND ADJUSTING BELT TENSION
1 DISCONNECT THE MACHINE FROM THE POWER
SOURCE
2. Open motor cover door to gain access to the motor.
3. Place a block of wood (C) Fig. 56. between the motor
and saw cabinet as shown.
NOTE:
It may be necessary
to raise the saw arbor in order to insert the wooden block.
Lower the saw arbor until the motor contacts the wood.
4. Loosen bolt (D) Fig. 56, and continue to lower the
saw arbor until all tension is removed from the belts (E).
Tighten bolt (D).
5. Raise the saw arbor slightly and remove the block of
wood (C) Fig. 56.

grooves of the arbor pulley (F) Fig. 57, and onto the
motor pulley.
9. When the new belts are assembled on the arbor
pulley (F) Fig. 57 and the motor pulley, loosen screw (D)
Fig. 56, and carefully let the motor rest on the belts.

1/4" deflection in the center span of the pulleys, using
light finger pressure. After tension is applied, tighten
screw (D) Fig. 56.
