CLEANING
Clean the chipper-shredder-vacuum thoroughly after
each use. Wash the bag periodically with water. Allow
to dry thoroughly in the shade. Do not use heat.
ENGINE
Refer to the separate engine manual for engine
maintenance instructions.
Maintain engine oil level as instructed in the separate
engine manual packed with your unit. Read and follow
instructions carefully.
Service air cleaner every 25 hours under normal
conditions. Clean every few hours under extremely
dusty conditions. Poor engine performance and
flooding usually indicates that the air cleaner should be
serviced. To service the air cleaner, refer to the
separate engine manual packed with your unit.
The spark plug should be cleaned and the gap reset
once a season. Spark plug replacement is
recommended at the start of each season; check
engine manual for correct plug type and gap
specifications.
Clean the engine regularly with a cloth or brush.
Keep the cooling system (blower housing area) clean to
permit proper air circulation which is essential to engine
performance.
Be certain to remove all dirt and combustible debris
from muffler area.
