Regular Maintenance
Clean Debris from engine &
Chipper
Service Interval: Before each use and every 100 hours.
The engine requires air flow to cool itself and for
combustion. Before each use, clean any debris from the
unit especially from around the air shroud intake, air filter,
and muffler. Every 100 hours, remove the engine air shroud
and clean out any debris from the engine cooling fins at the
locations shown in Figure 4. We recommend having this
service performed by an authorized dealer.
Inspect / Rotate Shredding
Hammers
Service Interval: every 25 Hours, or As Necessary
The shredding hammers of this unit can be rotated to
provide a new cutting surface as required. The triangular
hammers can be rotated twice, then flipped over for a total

over once. To inspect the shredding hammers:
1. Disconnect the spark plug wire and secure it away from
the spark plug.
2. Remove the small circular access panel (A, Figure 5) from
the back of the shredder housing.
3. Inspect the cutting edges of the triangular hammers
(Figure 6) and J-hammers (Figure 7).
