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.

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.

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.
