3. Before each use, inspect the Saw Blade. Using a dull Saw Blade will cause
excessive wear on the Motor of the Table Saw and will not produce a satisfactory
cut. Replace with a new Saw Blade when needed.
4. Before each use, open the Clean Out Door (12) and check for cleanliness. If
necessary, use a vacuum to remove excessive saw dust from the interior of the
Cabinet (1).
5. Every 12 months, lubricate the Geared Trunnion (52) and Front Trunnion (55).
The Trunnions each have a semicircle groove that needs to be lubricated with an
automotive wheel bearing grease.
6. Every 12 months, lubricate the Geared Bracket (102). The blade height Bracket
pivots on a steel rod. This should be lubricated with 6 or 7 drops of light machine
oil.
7. Every 12 months, lubricate the Worm Gears (18, 65). These should be lubricated
with an automotive wheel bearing grease.
8. To change the V-Belts, lower the Saw Blade to its lowest point. Loosen the Bolt
(35) on the Motor Bracket. Lift up on the Motor (34) to make the V-Belts (40) loose.
Remove the V-Belts from the Spindle Pulley (99) and Motor Pulley (38). Replace
and tension the V-Belts (the weight of the Motor should apply enough tension to
the V-Belts). Then, retighten the Bolt on the Motor Bracket.
(See Figure Z, next page.)
Check the V-Belt tension after the Table Saw has been used for a few hours.
Check and adjust as follows:
A. With moderate pressure, push the center of each V-Belt. Note the amount of
deflection. Deflection should be approximately 1/2”. (See Figure Z.)
B. If the deflection is not 1/2”, loosen the Bolt (35) on the Motor Bracket. Shift the
Motor up or down to increase or decrease the V-Belt tension. Then, retighten
the Bolt on the Motor Bracket. (See Figure Z.)
C. Check the V-Belt tension again. Also, make sure the Spindle Pulley (99) and
Motor Pulley (38) are lined up. (See Figure Z.)
9. To clean the exterior parts of the Table Saw, use only a clean cloth and mild
detergent to clean the body of the Saw. Then, dry. Do not immerse any
electrical part of the tool in any liquids.
