This Operators Manual covers a range of product
specifications for various models. Characteristics and fea-
tures discussed and/or illustrated in this manual may not
be applicable to all models. MTD LLC reserves the right
to change product specifications, designs and equipment
without notice and without incurring obligation.
Starting Engine
WARNING: Never run the engine
indoors or in a poorly ventilated area.
Engine exhaust contains carbon monox-
ide, an odorless and deadly gas.
IMPORTANT: Because this manual covers several
different model units, different starting instructions may
apply to your particular engine. Some engines may have
a fuel petcock, some may not. Some engines may have
On/Off switches, other may not. Some units will utilize a
choke system, while others will require priming. These
factors depend on what make and model engine comes
with your particular unit. For these reasons, please refer
to the engine operator’s manual for the correct starting
procedure.
1. Attach spark plug wire to spark plug. Make certain
the metal cap on the end of the spark plug is fastened
securely over the metal tip on the spark plug.
2. Engines with choke lever:
Move choke lever on engine to CHOKE position. (A
warm engine may not require choking).
Engines with primer:
Prime engine as instructed in separate engine manual.
3. The throttle control lever is located on the engine.
Move engine throttle control lever to FAST or START
position. See Figure 4-2.
4. Grasp starter handle and pull rope out slowly until
engine reaches start of compression cycle (rope will
pull slightly harder at this point).
NOTE: A noise will be heard when finding the start of
the compression cycle. This noise is caused by the flails
and fingers, which are part of the shredding mechanism,
and it should be expected until the impeller reaches full
speed.
5. Pull rope with a rapid, continuous, full arm stroke.
Keep a firm grip on starter handle. Let rope rewind
slowly.
6. Repeat the previous steps until engine fires. When
engine starts, move choke control (if equipped)
gradually to RUN position.
Stopping Engine
1. Move throttle control lever to STOP or OFF position.
2. Disconnect spark plug wire from spark plug and
ground against the engine.
NOTE: See your engine manual packed with your unit
for more detailed instructions.
Using The Chipper Shredder
Yard waste such as leaves and pine needles can be
raked up through the hopper assembly for shredding.
After material has been shredded by the flail blades
on the impeller assembly, it will be discharged out of
opening or into catcher bag. Do not attempt to shred
or chip any material other than vegetation found in a
normal yard (i.e. branches, leaves, twigs, etc.) Avoid
fibrous plants such as tomato vines until they are
thoroughly dried out. Twigs and small branches up to 3”
(2” for Model Series 450) in diameter can be fed into
the chipper chute.
Lowering The Hopper Assembly
1. With one hand grasp the handle at the top of the
hopper assembly and lift slightly.
2. With the other hand pull out on the release rod
and lower the hopper assembly to the ground. See
Figure 4-1.
To Empty Bag
1. Un-clip drawstring and loosen bag from chute
deflector opening.
2. 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.
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
SECTION 5: MAINTAINING YOUR CHIPPER SHRED-
DER. For best performance, it is also important to keep
the chipper blade sharp.

ler reaches full speed.
