EarthQuake 9060140 Manuel D’Utilisation

Regular Maintenance

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.

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.
