Cleaning The Reduction Chamber
WARNING: The impeller’s shredder
blade and chipper blades are sharp.
Wear leather work gloves to protect
your hands when cleaning out the
reduction chamber.
If the reduction chamber becomes clogged with debris,
the shredder screen can be pivoted upward so that you
can clean the surrounding area. To do so, proceed as
follows:
1. Stop engine, disconnect spark plug, and make certain
the chipper shredder has come to a complete stop.
WARNING: The muffler and surrounding
area will be hot if the engine has been
running. Use caution and protect your
hands if working near the muffler.
2. a. If attached, remove debris bag. Remove the two
wing knobs on either side of the chute deflector and
pivot the chute deflector upward. See Figure 8.
b. Remove the hairpin clip from the clevis pin which
extends through the housing and shredder screen.
See Figure 8. Remove clevis pin.
c. Pivot the shredder screen upward and clean the
surrounding area by scraping away debris.
3. Confirm that the spark plug wire is disconnected
and away from spark plug. Pull on the starter rope
two-to-three times to purge any remaining debris from
the reduction chamber
4. When the area is cleaned, pivot the shredder screen
downward and re-secure with the clevis pin and
hairpin clip removed earlier.
5. Reattach the debris collection bag to the chute deflec-
tor, if desired.
