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 of 6 sharp cutting surfaces. The J-hammers can be
flipped 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).
To rotate or replace the shredding hammers, see the
Troubleshooting and Repair section.
