Operation; Starting Engine - MTD 450 Serie Manual Del Operador

Operation

WARNING:
The operation of any 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.
• Allow the material in the hopper to be drawn into the
blades and shredded before adding additional debris
to the hopper. Failure to due 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.
Chipping
Branches up to two inches in diameter can be fed into the
chipper chute. Observe the following guidelines when chipping
branches:
• 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 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.
Emptying the Bag
1. Stop engine.
2. Un-clip drawstring and loosen bag from chute deflector
opening.
3. 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 5-1.
