4. Remove six flange nuts which secure hopper inlet guide to
impeller housing. See Fig. 7-3A.
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 Fig. 7-3B.
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 Fig. 7-3C.
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.
