MAINTENANCE (SAW)

13.Replace the spindle bearings as soon as they begin to make any strange noises. Worn bearings can destroy blades very quickly.

14.Grease pivot bearings periodically.

CUTTING HEAD ALIGNMENT (BLADE)

Make certain the cutting head is aligned properly. Misalignment can adversely affect blade life.The motor/engine plate is slotted so adjustment to the blade can be made as needed.The left side has vertical slots, and the right side has horizontal slots.To adjust the cutting head either vertical or horizontally perform the following:

VERTICAL ADJUSTMENT

Remove the motor or engine from the mounting plate. Loosen the pivot bearing bolts (2) on the left side of the mounting plate. Move the pivot bearing to the extreme top of the slots in the mounting plate. Thread a 3/8-16 bolt (adjusting bolt) down through the hole in the top of the mounting plate.Tighten the bolt against the bearing.

This will raise the mounting plate. Continue to tighten the bolt until the blade is perpendicular to the conveyor cart.Tighten the pivot bearing bolts. Remove the adjusting bolt and reassemble.

HORIZONTAL ADJUSTMENT

Loosen the pivot bearings (2) on the right-side of the mounting plate. Slide the pivot bearing forward or backwards as needed, until the blade is parallel with the conveyor cart.Tighten the pivot bearing bolts.

BEARING LUBRICATION CARE

There are two (2) grease points (Figure 30) for the MP1 gasoline model saw. Use only Premium Lithium 12 based Grease, conforming to NLG1 Grade #2 consistency.Grease daily.

Figure 30. Zerk Fittings (Lubrication)

CAUTION:

When loosening the handle lock, hold onto the front of the motor/engine plate handle to prevent the plate from raising rapidly, possible causing the saw to become unstable. Let the plate raise slowly.When removing the spring

from the pivot shaft, MAKE CERTAIN the motor/engine plate is supported to prevent the cutting head from dropping.

CUTTING HEAD REMOVAL

To remove the cutting head (Figure 31) perform the following:

1.Loosen the knobs (2) located on each side of uprights.

2.Slide the hooks (2) up and away from the pivot shaft.

3.Removethehandlelockthatfastensthebladeheightadjusting arm to the motor/engine plate.This is accomplished by simply removing the cotter pin.

4.Disconnect thespring fromthe pivot shaftbyraising thecutting head until the tension is relieved from the spring.

5.To reassemble the cutting head, reverse these steps.
