REPLACING BELTS AND ADJUSTING
BELT TENSION
DISCONNECT MACHINE FROM POWER
SOURCE.
1. Remove motor cover to gain access to the motor.
2. Place a block of wood (C) Fig. 51, 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.
3. Loosen bolt (D) Fig. 51, and continue to lower the saw
arbor until all tension is removed from the belts (E).
Tighten bolt (D).
4. Raise the saw arbor slightly and remove the block of
wood (C) Fig. 51.
5 Lower the saw arbor. Remove the belts (E) Fig. 51,
one at a time from the motor pulley.
6. Remove the belts (E) Fig. 52, one at a time from the
arbor pulley (F).
7. Assemble the three new belts, one at a time in the
grooves of the arbor pulley (F) Fig. 52, and onto the motor
pulley.
8. When the new belts are assembled on the arbor
pulley (F) Fig. 52 and the motor pulley, loosen screw (D)
Fig. 51, and carefully let the motor rest on the belts.
9. Correct belt tension is when there is approximately
1/4" deflection in the center span of the pulleys, using
light finger pressure. After tension is applied, tighten
screw (D) Fig. 51.

CHANGING THE BLADE
DISCONNECT MACHINE FROM
POWER SOURCE.
1. NOTE: Two 7/8" wrenches are supplied with the saw
for changing the blade: a box end wrench (A) Fig. 50 &
50A, and open end wrench (B) Fig. 50 & 50A. Use only
10" saw blades rated for 3000 RPM or higher with 5/8"
arbor holes.
2. Remove table insert (C) Fig. 50, and raise saw blade
to its maximum height.
3. Place the open end wrench (B) Fig. 50 on the flats of
the saw arbor to keep the arbor from turning, and use
wrench (A), to turn the arbor nut toward the front of the
saw. Remove arbor nut, blade flange, and saw blade.
4. Assemble the new blade, making certain the teeth
point down at the front of the saw table, and assemble
outside blade flange and arbor nut. With wrench (B) Fig.
50, on the flats of the arbor to keep it from turning,
tighten arbor nut
by turning wrench (A) Fig. 50A toward
the rear of the saw.
5. Replace table insert. IMPORTANT: When installing
the table insert, make certain to hold on to the blade
guard.
