Your chipper/shredder engine requires routine mainte-

 

 

nance for long-life and trouble-free operation. Consult

 

 

the manufacturer’s manual provided with this unit for

 

 

specific recommendations and service procedu es. In

 

 

general, however, your engine requires nly the p even-

Shredding Hammers

 

 

 

The cutting edges of the shredding hammers may even-

 

 

tually wear out, requiring rotation of the hammer, or com-

 

 

plete replacement if all cutting edges have b

n used.

edge dulls, then flipped over once and rotated again for a

 

 

 

 

total of six cutting edges. J hammers can be flipped over

once (Model 5/14 only), for a total of two cutting edges.

 

 

Shredding hammers need to be rotatedReproductionwhen shredding

 

performance becomes sluggish, or when the edges of

 

 

the hammers wear down, as shown in figures 15 and 16.

 

 

To inspect and service the shredding hammers, follow these steps:

1.Turn engine off, allow rotor to stop completely, and disconnect spark plug wire.

2.See Figure 18. Detach the shredder hopper from the rotor housing, leaving the liner and handle in place on the hopper.

3.Remove the rotor housing by unscrewing the

5/16-18 hex nuts that hold it to the fan housing.
