MAINTENANCE AND STORAGE
Do not use the chipper-shredder if any part is lost
or damaged while cleaning. Get lost or damaged
parts replaced before use. Do not use the chipper-
shredder if any part is loose, not fitting correctly or
not fully re-assembled.
WARNING
Chipper-Shredder Maintenance
Make certain that the chipper-shredder is kept clean
and stored properly. Only operate the unit on a flat, level
surface in a clean, dry operating environment. DO NOT
expose the unit to extreme conditions, excessive dust,
dirt, moisture or corrosive vapors.
Inspect all air vents and cooling slots to ensure that they
are clean and unobstructed.
Inspect all chutes and housing and make sure they are
free of dirt, dust, and debris.
Check and tighten all bolts and nuts. It is possible for
connections to vibrate loose over time.
Air Filter
1. Unscrew wing nut to remove the air filter cover.
2. Remove the supporter and foam element.
3. Tap the foam element to remove dirt and debris. Use
compressed air (25 PSI) to clear debris.
4. For the foam element: Wash in liquid detergent and
water. Squeeze thoroughly dry in a clean cloth.
5. Saturate in clean engine oil.
6. Squeeze in a clean, absorbent cloth to remove all
excess oil.
7. Reassemble the elements and the supporter.
8. Reattach the air filter cover and snap in place.
9. Tighten wing nuts.
DO NOT use a garden hose or water to clean the
engine or chipper-shredder.
CAUTION
Water can contaminate the fuel system and can enter the
engine through the cooling slots and damage the engine.
Cleaning
Clear the debris from the chutes and engine. Use a damp
cloth to clean exterior surfaces of the engine and chipper-
shredder.
Use a soft bristle brush to remove excess dirt and oil. Use
an air compressor (25 PSI) to clear dirt and small debris.
Wipe all metal parts with an oily rag to help prevent rust
and corrosion.
