Now that you have set up your chipper shredder

for operation, get aquainted with its controls and

features. These are described below and illustrated

on this page. This knowledge will allow you to use

your new equipment to its fullest potential.

Chipper Chute

Allows twigs and small branches up to 3" in diam-

eter to be fed into the impeller for chipping. See

Figure 9.

Hopper Assembly

Allow leaves and small branches up to 1/2 diameter

to be fed into the impeller for chipping and shred-

ding. Material can be raked into hopper assembly

by lowering the hopper assembly. See Figure 9.

Release Rod

The release rod is located on the impeller bracket

assembly and it is used to release or lock the hop-

per when raising or lowering. See Figure 9.

Tow Bar (if Equipped)

Use the tow bar to tow the chipper shredder behind

a tractor to a job site. See Figure 9.

NOTE:Ifyour unit isnotequippedwitha towbar,you
