Engine Dust Filter

1. The engine dust filter should be cleaned each hour
and after each use by shaking out the dust and then
rinsing with mild detergent. The filter can also be
vacuumed with a wet-dry vacuum.
2. Squeeze out the excess water (Do Not Wring).
3. Allow the filter to air dry.
Note: Failure to maintain a clean engine filter will
cause the engine to overheat. Also, it may cause
the exhaust emissions to elevate to harmful levels. If
necessary, replace with (Part # 56384280).

Cooling Fin Maintenance

A. Remove blower housing and any other shrouds.
B. Clean the cooling fins as necessary using
compressed air or pressure washer.
C. Reinstall all housings and shrouds.
Inspect Pads and Pad Holders
1. Push machine to level surface.
2. Turn off LP cylinder and remove it.
3. Rock the machine back by lifting up the front of the
machine until it rests on the handle grips.(See "Pad
Change" section.)
4. Remove centering device and inspect the pad. If the
pad has worn less than 1/4" (6 mm), replace it.
5. Inspect the pad holder for cracks or damage. If the
pad holder does not have any damage proceed to
step 9.
WARNING! A damaged pad holder rotating at a high rate
of speed may be an extreme hazard if it should come
apart.
6. If the pad holder needs to be removed, a 3/4"
wrench will be required. Locate the wrench flats
on top of the spindle shaft. With the spindle shaft
secure, turn the pad holder counter clockwise until it
is free of the spindle shaft.
7. Save the washer and/or spacer that is on the spindle
shaft. Be sure they are in place when the pad holder
is re-installed.
8. When threading the pad holder onto the spindle
shaft, use the wrench to keep the shaft from turning.
Be sure the pad holder is tight before proceeding.
9. Secure the pad with the centering device.
10. Lower the machine.

Belt Maintenance

1. Push machine to level surface.
2. Turn off LP cylinder and remove it.
3. Place the machine in the pad change position by
lifting up on the front of the machine until it rests on
the handle grips.
4. Rotate the pad drive and inspect the belt.
5. If cracks or excessive wear is present, the belt needs
to be replaced.
6. To check for the proper tightness, squeeze the belt
together. The belt should depress between 1/4"
(0.6 cm) and 1/2" (1.3 cm).
