Move choke lever to CHOKE position. (A warm

Grasp the starter handle and pull the rope out
slowly until resistance is felt. When it becomes
slightly harder to pull the rope, slowly allow the rope
to recoil. Then pull rope with a rapid, continuous,
full arm stroke. Keep a firm grip on starter handle.
Repeat the previous steps until engine starts. When
engine starts, move choke control gradually toward
the RUN position until the engine is running
smoothly.
NOTE:
A “clanky” noise may be heard when pulling
the starter rope. It is completely normal and does NOT
indicate a malfunction of any kind. The noise is caused
by the flails (part of the shredding mechanism) pivoting
on the chipper shredder’s impeller as it rotates.
Allow the rope to recoil slowly.
WARNING:
Never run the engine indoors
or in a poorly ventilated area. Engine exhaust
contains carbon monoxide, an odorless and
deadly gas.
Shredding
Yard waste such as leaves and pine needles can be
placed 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.
Avoid placing twigs longer than 24 inches into the
hopper. Twigs longer than 24 inches may result in a
clogged hopper.
Never place branches with a diameter
IMPORTANT:
greater than 1/2-inch in the hopper. Doing so can result
in serious damage to your unit’s shredder blade, flails or
impeller.
Clearing the Hopper
Should the hopper become clogged with debris during
operation, proceed as follows:
Grasp the handle with both hands and gently
agitate the chipper shredder to help loosen debris,
drawing it into the impeller.
If the clog does not clear, proceed as follows:
Stop engine.
Use your hands to remove any debris found near
the top of the hopper.
Use a branch (or other available device, i.e.
broomstick) to dislodge debris located toward the
base of the hopper.
Restart engine.
NOTE: If you’re unable to pull the starter rope as a
result of accumulated debris near the impeller, follow
instructions under the heading Cleaning the
Reduction Chamber.
