Snapper 5/14 SERIES - Manual (Page 23)

REPAIR
Engine Service
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 procedures. In
general, however, your engine requires only the preven-
tive maintenance indicated on the Normal Care
Schedule.
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 been used.
Triangular hammers can be rotated twice after the first
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 rotated when 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.
See Figure 19.
