Adjusting V-Belt Tension
This must be done after approximately 16 hours of operation. During this first 16 hours the V-belts will stretch
and seat into the pulley grooves. After this 16 hours, the V-belts must be tensioned or V-belt life will be
severely reduced.
NOTE: Pulleys and belts run warm. This is a normal condition. Allow them to cool before making adjust-
ments. Some black dust at the bottom of the belt housing is normal during the life of the V-belt.
The correct tension for the V-belts is 1/4" deflection when pushing the center with moderate pressure. Adjust/
replace belts by using the motor mount bolts (Figure 19-B) to control the tension. NOTE: Always change belts
as a matched set when replacing. If only one or two is replaced, the belt tension may not be even, causing
premature belt failure and possible injury.
Adjusting Alignment on Pulley
Using a straightedge, check to see if the motor pulley is in line with the shaft pulley (Figure 18). If they are not
in line, loosen screws as shown in figure 19-A. Move motor to left and right until adjusted to proper position
and then tighten screw again.

Anti-Kickback Fingers
NOTE: Proper operation of the anti-kickback fingers is
essential for the safe operation of this machine and to
prevent serious operator injury.
The anti-kickback fingers hang from a rod suspended
across the cutter head casting and should be inspected
regularly. Check the fingers (Figure 21) to ensure that
they swing freely and easily. If the fingers do not swing
freely and easily, blow or brush out the saw dust, and
clean them with a wood resin solvent. Do not apply oil
or other lubricants, which would attract dust and dirt.
