Adjust BeltTension Gasoline Powered Saws

MP2 MASONRY SAW — MAINTENANCE (SAW)

Adjust BeltTension (Gasoline Powered Saws)

1.Remove engine-to-jackshaft and jackshaft-to-bladeshaft belt guards.

2.Check for proper belt tension on jackshaft-to-bladeshaft belts and engine-to-jackshaft belts.

4-5 lbs of force applied to the mid-point between jackshaft and bladeshaft pulleys should deflect the belt approximately 3/16" on a used belt.

4-5 lbs of force applied to the mid-point between engine and jackshaft pulleys should deflect the belt approximately 1/8".

To adjust engine-to-jackshaft belts only:

1.Loosen engine mounting bolts.

2.Adjust engine adjusting nuts to apply proper tension while maintaining pulley alignment and belt parallelism. Check pulley alignment and parallelism with a straight edge from jackshaft pulley to engine pulley.

It is very important that the

NOTE jackshaft and blade arbor remain parallel to each other.

This can be accomplished by using

the adjusting bolt located on the engine mounting plate to

help keep the jackshaft from cocking.

3.When proper belt tension and parallelism have been achieved, tighten engine mounting bolts.

To adjust jackshaft-to-bladeshaft belt:

If the jackshaft-to-bladeshaft belt requires adjustment, it will also be necessary to adjust the engine-to-jackshaft belts.

1.Loosen the 4 jackshaft mounting bolts, the 4 engine mounting bolts, and the jackshaft adjuster screw jam nuts (Loosen the mounting bolts only enough for the jackshaft and the engine to slide easily.)

2.Adjust jackshaft-to-bladeshaft belt first. To increase tension, tighten adjuster on bladeshaft belt side.To help maintain belt parallelism, loosen the jackshaft adjuster screw on the engine side the same number of turns that the bladeshaft side adjuster screw was tightened. Using a straight edge on the bladeshaft pulley to the jackshaft pulley, check for pulley alignment and belt parallelism.

3When belt tension is correct, pulleys are aligned, and belts are parallel, tighten jackshaft mounting bolts and adjuster screw jam nuts.

4.Check for proper engine-to-jackshaft belt tension (4-5 lbs with 1/8" deflection at mid-point between pulleys.)

5.Adjust engine adjuster bolts to apply proper tension while maintaining pulley alignment and belt parallelism. Check pulley alignment and parallelism with a straight edge from jackshaft pulley to engine pulley.

6.When proper belt tension and parallelism have been achieved, tighten engine mounting bolts.

Reinstall belt guards. Test saw operation.

Adjust BeltTension (Electric Powered Saws)

1.Remove the three belt guard screws securing the belt guard to the frame and remove the belt guard.

2.Loosen the four motor mounting bolts.

3.To increase belt tension, tighten the two adjusting nuts on the back of the motor plate.

Proper belt tension is 4-5 lbs. of force with approximately 3/16" of belt deflection measured at a point midway between the pulleys.

4.Adjust motor adjusting nuts to apply proper tension while maintaining pulley alignment and belt parallelism. Check pulley alignment and parallelism with a straight edge from motor pulley to bladeshaft pulley.

5.When proper belt tension and parallelism have been achieved, tighten engine mounting bolts and re-attach the belt guard.
