5 INCH CHIPPER/SHREDDER

SERVICE & MAINTENANCE

WARNING

BEFORE INSPECTING OR SERVICING ANY PART OF THIS MACHINE, SHUT OFF POWER SOURCE, 

AND MAKE SURE ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.

1. 

Place a blade on the rotor and attach with two 5/16 × 

1" bolts. Torque to 25 ft‑lbs. Repeat for the remaining 

blades.

2.  Reinstall the discharge screen by placing the top lip 

of the screen into the slot under the top slope of the 

chipper body and rotating the screen so that the bolt 

holes align with the holes in the chipper body.

3. 

Secure using two 5/16" × 3/4" bolts and nuts; torque 

to 17 ft-lbs.

4.  Reinstall the discharge door.

5.5 INSTALLING THE BLADES

Figure 5.3, Examples of Damage to Knives

Do not attempt to sharpen shredder knives. Inspect the 

knives often for signs of damage. 
If a knife has any sign of cracking or is broken in any way, 

it should be replaced immediately.

5.6 SHREDDER KNIVES MAINTENANCE

5. 

Remove an equal amount off each blade to maintain 

rotor balance.

6.  Small imperfections such as nicks and burrs on 

the flat side of the blade will not affect the chipping 

performance of the machine.

7.  For blades that have been repeatedly sharpened, 

ensure that the sharpened surface extends past 

the chipping slot opening. If it does not extend past 

the  opening,  the  blades  should  be  replaced  (see 

Section 5.3).

1.  Remove the discharge door and discharge screen.
2.  Remove the rear side access cover.
3.  Work with one knife shaft at a time. Remove the  

#10-24 bolt and nut from the knife shaft and discharge. 

Do not reuse.

4.  Using a hammer and punch, drive the knife shaft 

through the access hole on the rear of the machine.

5.  Remove the spacers and shredder knives. Be careful 

to keep track of the order the spacers were installed 

on the shafts so they can be returned to the original 

locations. If the spacers and knives are not installed 

correctly, the rotor will be out of balance and will not 

have proper shredding action.

6.  Reverse or replace the knives and reassemble onto 

the rotor. Install a new #10-24 bolt and nut through 

the spacer and shaft. Torque to 36 in-lbs.

7.  Repeat for remaining shafts.
8.  Replace the rear access cover, discharge screen and 

discharge door. Torque all 5/16" bolts to 17 ft‑lbs.

5.7 REMOVING THE SHREDDER KNIVES

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. Never 

reuse shafts or spacers if they show signs of wear or 

abuse. Always install new parts when repairing.
