Shredder Blade Care
WARNING:
The shredder blade is sharp.
Wear leather work gloves to protect your
hands.
1. Stop engine, disconnect spark plug, and make
certain that all moving parts have come to a
complete stop.
2. Remove the two flange nuts (and hex bolts)
which secure the hopper support bracket to
the impeller housing. Retain the hardware. See
Figure 4-3.
Figure 4-3
3. Pivot the shredder screen upward as
instructed under the heading Cleaning the
Reduction Chamber.
4. Remove six flange nuts which secure hopper
inlet guide to impeller housing. See A in Figure
4-4.

5. Carefully separate the hopper assembly from
the impeller housing and set it aside.
6. Insert a piece of wood into the chute deflector
opening to stabilize the impeller and prevent
it from rotating when removing the shredder
blade.
7. Remove the two internal hex screws, hex
lock nuts, and lock washers which secure the
shredder blade to the impeller. See B in Figure
4-4.
NOTE:
Use a 3/16” hex key (Allen) wrench
on the outside of the shredder blade and a
1/2” box (or socket) wrench on the inside of
the shredder blade. Hold the Allen wrench
stationary and rotate the box (or socket)
wrench to loosen the nut.
8. Remove the hex bolt, lock washer, and flat
washer to completely free shredder blade. See
C in Figure 4-4.
IMPORTANT:
If sharpening the blade for
reuse, follow the original angle of grind as
a guide. Make certain each cutting edge
receives an equal amount of grinding to
prevent an unbalanced blade. Remove metal
from the heavy side until it is balanced evenly.
IMPORTANT:
When reassembling the blade,
tighten center bolt to between 45 ft.-lbs and
58 ft.-lbs and the two out bolts to between 20
ft.-lbs and 25 ft.-lbs.
Off-Season Storage
• Allow the unit to run and clear out all debris
for a short time before shutting the unit down
before storage.
• When storing the chipper shredder in an
unventilated or metal storage shed, care
should be taken to rustproof the non-painted
surfaces. Using a light oil or silicone, coat the
equipment, especially any springs, bearings,
and cables.
• Remove all dirt from exterior of engine and
equipment.
• Follow lubrication recommendations.
• Refer to engine manual for correct engine
storage instructions.
• Store equipment in a clean, dry area. Do not
store in an area where equipment is present
that may use a pilot light or has a component
that can create a spark.
9. Remove the hairpin clip from the clevis pin
which extends through the housing and
shredder screen. See B in Figure 4-1. Remove
clevis pin.
10. Pivot the shredder screen upward. See C in
Figure 4-1. Clean the surrounding area by
scraping away debris.
11. Confirm that the spark plug wire is
disconnected and away from spark plug. Pull
on the starter rope two-to-three times to
clear any remaining debris from the reduction
chamber.
12. When the area is cleaned, pivot the shredder
screen downward and re-secure with the
clevis pin and hairpin clip removed earlier.
13. Reattach the debris collection bag to the chute
deflector, if desired.
