Maintenance; Changing The Saw Blade - Delta UNISAW 34-801 Instruction Manual

CHANGING THE SAW BLADE

1. DISCONNECT MACHINE FROM POWER SOURCE.
2. NOTE: Two wrenches are supplied with the saw for
changing the saw blade; a box end wrench and open end
wrench.
3. Remove table insert and raise saw blade to its
maximum height.
4. Place the open end wrench (B) Fig. 50, on the flats of
the saw arbor to keep the arbor from turning, and using
wrench (A), turn the arbor nut (C) clockwise. Remove
arbor nut, blade flange and saw blade.
5. Assemble the new blade, making certain the teeth are
pointing 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) counterclockwise.
6. Replace table insert.
NOTE: Use only 10" saw blades with 5/8" arbor
holes, rated for at least 4000 RPM.
REPLACING BELTS AND
ADJUSTING BELT TENSION
1. DISCONNECT MACHINE FROM POWER SOURCE.
2. Open motor cover door to gain access to the motor.
3. 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.
4. Loosen bolt (D) Fig. 51, 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

arbor pulley (F).
8. Assemble the three new belts, one at a time in the
grooves of the arbor pulley (F) Fig. 52, and onto the motor
pulley.
9. 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.
10. 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
