the top down.
4. Clean any trash or debris out from the screen area.

in the chipper body and push the bottom of the screen
inward so bolt holes align.
6. Install the bolt from the underside upward through the

The belt guide aids in disengaging the chipper/shredder.
If problems arise with engaging and disengaging the unit,
follow the instructions below. These instructions also
adjust the lower belt guard.
1. Remove upper shield to expose the belt and pulleys.
2. loosen set screws and using a straightedge align the
engine pulley with the idler pulley and the rotor pulley
with the engine pulley. Tighten all set screws.
3. Engage the clutch with the belt in place and check idler
engagement. The idler pulley should impact the belt in
the center of the pulley. All pulleys must be in perfect
alignment. Torque pulley set screws to 160 In-lbs.
4. If idler pulley will not remain in alignment with engine
and rotor pulleys, it may be necessary to replace the
idler bracket bushings.
5. There should be 1/8" clearance between the belt and
the lower belt guard when the clutch is engaged. Adjust
by loosening the mounting bolts and repositioning the
guide. Retighten mounting bolts.
6. Reinstall upper shield.
7. From underneath, check the alignment of lower belt
guard with a post card (Figure 5.4). With the clutch
engaged, there should be enough room between the
belt and the side of the guard for the card to slide along
the belt. With the clutch disengaged, the card should
not be able to slide. Adjust if necessary.
