Equipment Care
• Clean the chipper shredder thoroughly after
each use.
• Wash bag periodically with water. Allow to dry
thoroughly in shade.
• If the reduction chamber becomes clogged,
remove and clean as instructed below.
• Allow the unit to run and clear out all debris

service the air cleaner, refer to the engine
manual.
• The spark plug should be cleaned and the gap
reset once a season. Check engine manual for
correct plug type and gap specifications.
• Clean engine regularly with a cloth or brush.
Keep the top of the engine clean to permit
proper air circulation. Remove all grass, dirt,
and combustible debris from muffler area.
Cleaning The Reduction Chamber
WARNING: The impeller’s shredder
blade and chipper blades are sharp. Wear
leather work gloves to protect your hands
when cleaning out the reduction
chamber.
If the reduction chamber becomes clogged with
debris, the shredder screen can be pivoted upward
so that you can clean the surrounding area. To do so,
proceed as follows:
1.
Stop engine, disconnect spark plug, and make
certain the chipper shredder has come to a
complete stop.
WARNING: The muffler and surrounding
area will be hot if the engine has been
running. Use caution and protect your
hands if working near the muffler.
2.
If attached, remove debris bag.
Remove the two wing knobs on either side
of the chute deflector and pivot the chute
deflector upward. See A in Figure 4-1.

which extends through the housing and
shredder screen. See B in Figure 4-1. Remove
clevis pin.
4. Pivot the shredder screen upward. See C in
Figure 4-1. Clean the surrounding area by
scraping away debris.
5. Confirm that the spark plug wire is
disconnected and away from the spark plug.
Pull on the starter rope two-to-three times to
clear any remaining debris from the reduction
chamber.
6. When the area is clean, pivot the shredder
screen downward and re-secure with the
clevis pin and hairpin clip removed earlier.
7. Reattach the debris collection bag to the chute
deflector, if desired.
Chipper Blade Care
WARNING: The impeller’s chipper blades
are sharp. Wear leather work gloves to
protect your hands.
1. Stop engine, disconnect spark plug, and make
certain the chipper shredder has come to a
complete stop.
2. Pivot the shredder screen upward as
instructed under the heading Cleaning the
Reduction Chamber.
3. Remove the chipper chute support brace from
the frame by removing the two hex bolts and
saddle washers which secure it. See A in Figure

4. Remove the chipper chute by removing three
hex nuts and washers which secure it to the
impeller housing. See B in Figure 4-2.
5. Rotate the impeller by hand until one of the
two chipper blades is visible through the
impeller housing opening.
6. Remove the blade by removing the internal
hex screws, lock washers and hex nuts which
secure it to the impeller. See C in Figure 4-2.
Retain the hardware.
NOTE:
Use a 3/16” hex key (Allen) wrench on
the outside of the blade and a 1/2” box (or
socket) wrench on the inside of the impeller.
Hold the Allen wrench stationary and rotate
the box (or socket) wrench to loosen the nut.
7. Install a replacement blade with the hardware
removed earlier or sharpen.
IMPORTANT:
When sharpening the blade,
protect hands by using gloves. Follow the
original angle of grind and make sure to
remove an equal amount from each blade.
8. To replace the other blade, rotate the impeller
to expose the second blade and repeat the
steps above.
NOTE:
Make certain blades are reassembled
with the sharp edge outward (toward the
chipper chute). Torque hardware to between
