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,

can clean the surrounding area. To do so, proceed as
follows:
• Stop the engine and wait untill all moving parts
have come to a complete stop.

spark plug.
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.
• Remove the two wing knobs on either side of the
discharge chute and pivot the discharge chute
upward. See Figure 8.
• Remove the hairpin clip from the clevis pin which
extends through the housing and shredder screen.
See Figure 8. Retain the clevis pin and hairpin clip.
• Pivot the shredder screen upward and clean the
surrounding area by scraping away debris.

• 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

screen downward and re-secure with the clevis pin
and hairpin clip removed earlier.
