processed
may bounce back from inlet openings or be thrown from the discharge chute. Long hair or loose clothing
may be pulled sucked into the inlet openings.
Do not place branches over 1/2 inch diameter into the large Shredder Hopper. Branches over 1/2 inch in
diameter should be placed in the Small Chipper Chute.
If the chipped shredder jams or becomes clogged, immediately shut off the engine and wait for all
moving parts to come to a complete stop before clearing.
Do not install remove, adjust, or service the discharge screen or any other part while the engine
is running. Blade contact can occur.

TowBart'_
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.
