USING YOUR CHIPPER-SHREDDER
AWARNING: Do not attempt to shred or
chip any matedal otherthanvegetation
foundina normalyard(i.e., branches,
leaves,twigs,etc.).
The chipper-shredderis designed for two
different methodsof operation.
a. Leaves and small branchesupto 1/2"
diameter (maximum)can be fed intothe
hopperassemblywhen it is in the raisedor
loweredposition.See figure12.
b. Bulky material,such as stalksor heavy
branches,up to 3" in diameter shouldbe
fed intothe chipperchute. See figure 12.
AWARNING: Do not put material larger
than is specifiedinto the hopper, and/or into
the chipperchute. Personalinjuryor
damage to the machinecould result.
If it becomesnecessaryto pushmaterialintothe
chipper-shmdder,use a smalldiameter stick-
NOT YOUR HANDS. The stickshouldbe small
enoughthat itwill be groundup if it gets intothe
impellerassembly.
LOWER THE HOPPER ASSEMBLY
To lowerthe hopper assembly, use one handto
grasp the hand-hold at the top of the hopper
assemblyand liftslightly.See figure 5.
Pullup onthe release bar, and lower the hopper
assemblyto the ground.Release the bar. See
figure 5.
AWARNING: Never remove chute deflector
tillthe unit has completely stopped.Never
shut offthe engine until all chipping is
completed.
For best performance, it is important to keep the
shreddingblade and the chipper blades sharp.If the
composition of the material being discharged
10
changes(becomesstdngy,etc.) or if the rate atwhich
the material is discharged slows down considerably, it
is likely that the shredding blade and/or chipper
blades are dull and need to be sharpened or
replaced. Refer to Service and Adjustments section.
IMPORTANT: There is a flail screen located inside
the housing in the discharge area. If the flail screen
becomes clogged, remove and clean as instructed in
the Service and Adjustments section.
AWARNING: The chipper-shredder
discharges materialswithconsiderable
velocity.Keep away from the area aroundthe
dischargechute. Always stopthe engine and
disconnectsparkplugwirewhen removingor

NOTE: Fuel stabilizer is an acceptable alternativein
minimizing the formation of fuel gum deposits during
storage.
Add stabilizerto gasoline infueltank orstorage
container.
Always follow the mix ratiofoundon stabilizer
container.
Run engineat least 10 minutesafter adding
stabilizerto allow the stabilizerto reachthe
carburetor.
Donot drain the gas tank and carburetorif using
fuel stabilizer.Drainallthe oilfrom the
