SUBJECT: SHREDDER KNIFE

KIT # 75502-00

FITS MODEL: SC2206 CHIPPER/

SHREDDER

The Shredder Knife Kit is a replacement kit to replace exist­ing dull or damaged knives. The serrated shredder knives
are designed to offer long life and can be reversed if they
become dull. To remove the knives or to install a complete
new shredder kit proceed as follows.

WARNING

Before inspecting or servicing any part of this machine,
shut off power source, remove key, disconnect the bat­tery cables and make sure all moving parts have come
to a complete stop.

NOTE

IMPORTANT

The serrated edge of the shredder knives should face
the same direction as the cutting edge of the chipper
blades. Never reuse the #10-24 nut and bolt, always
install new parts when repairing. Never reuse shafts
or spacers if they show signs of wear or abuse. Install
new ones.

Push the shaft out of the rotor assembly and remove the 4.
knife spacers. If you keep track of the order the spacers
were installed on the shafts it will be easier to put the
new ones in the right location (see back page). If the
spacers and knife sections are not installed properly,
the rotor will be out of balance and will not have proper
shredding action.

Install new knife sections and spacers onto the shaft. 5.
Secure the shaft with a new 10-24 x 1-1/8" screw and
10-24 nylock nut. Torque to 36 in-lb.

Repeat for the remaining shaft.6.

Replace engine, plate and rotor assembly and secure 7.
with the eight 5/16" nuts.

This shredder kit uses an improved knife pattern to
provide more complete shredding, durability, and
easier feeding. Care must be taken to insure the
knives and spacers are installed properly to maintain
rotor balance.

INSTALLATION STEPS:

Remove the eight 5/16" nuts holding the engine and 1.
plate to the frame (see Figure 1).
