Operation
WARNING:
chipper shredder can result in foreign
objects being thrown into the eyes,
which can damage your eyes severely.
Always wear the safety glasses provided
with this unit or eye shields before
chipping or shredding and while
performing any adjustments or repairs.
Starting Engine
Refer to the engine operator's manual for the starting
instructions.
Lowering the Hopper
1. With one hand grasp the handle at the top of
the hopper and lift slightly.
2. With the other hand pull out on the release
rod and lower the hopper to the ground.
Shredding
Yard waste such as leaves and pine needles can be
raked up in the hopper for shredding. After material
has been processed by the shredder blade and flails,
it will be forced out of the chute deflector, and, if
attached, into a debris collection bag.
Observe the following guidelines when shredding
yard debris:
• Never attempt to shred material other than
normal yard debris (leaves, twigs, pine cones,
etc.).
• Avoid shredding fibrous plants such as tomato
vines until they are thoroughly dried out.
Fresh vines do not shred well and tend to wrap
themselves around the impeller and flails.
• Place reasonable amounts of debris into the
hopper at a time. Do not overload the hopper.
•
Chipping
Branches up to two inches in diameter can be fed
into the chipper chute. Observe the following
guidelines when chipping branches:

Allow the material in the hopper to be drawn
into the blades and shredded before adding
additional debris to the hopper. Failure to do
so may result in a clogged hopper, clogged
chute deflector or a stalled engine.
IMPORTANT:
The flail screen is located inside
the housing in the discharge area. If the flail
screen becomes clogged, remove and clean as
instructed in the Maintenance & Adjustments
section. For best performance, it is also
important to keep the chipper blade sharp.
Keep both hands firmly on the branch as you
feed it into the chipper chute.
Never feed more than one branch into the
chipper chute at a time.
Never feed anything other than branches (or
wood) into the chipper chute.
Apply intermittent pressure (force, in short
pulses) while feeding larger branches into the
chipper chute, to avoid bogging or stalling the
engine.
IMPORTANT:
Never feed branches with
a diameter greater than two (2) inches into
the chipper chute (Model Series 450) and (3)
inches for Model Series 460. Doing so can
result in serious damage to your unit's chipper
blades, flails or impeller.
NOTE:
For best performance, always operate
the unit with sharp chipper blades. If a
noticeable loss in performance is encountered
while chipping branches, the chipper blades
should be replaced.
Stop engine.
Un-clip drawstring and loosen bag from chute
deflector opening.
Empty bag and reattach to the discharge
chute opening. Pull on the drawstring until
the bag is tight around the chute opening and
clip the drawstring tight against the chute
deflector. See Figure 3-2.
