3 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.

See Figure 5.2 for illustration.

1.  Clean away any material that may be between the 

blade and mounting surface on the rotor. 

2.  Place a blade (6) on the rotor and attach with two 

5/16-18 x 5/8" bolts (5). Torque to 25 ft-lb. Repeat for 
the second blade. 

3.  Reinstall the shredder screen (4) in the machine with 

îEROWDQGÀDQJHQXW

4.  Lower the discharge door/shield (1) into the normal 

operating position. 

5.  Remove rotor lock.

The blades can be ground on a bench grinder or by a 
professional. 

1.  Never sharpen or grind the mounting surfaces of 

the blades. This will cause the edge to roll and the 
blade will be damaged, resulting in poor chipping 
performance.

2.  Regrind the angled edge of the chopping blades to 

45 degrees (Figure 5.3). Use the blade angle gauge 
plate when sharpening the blades to achieve the 
proper angle (see Figure 5.4).

properly and completely installed into upper slot of the 
housing. Failing to do so may cause knives to make 
contact with discharge screen during operation.

NOTE

3.  Be careful when grinding so that the blade does 

not become overheated and change color. This will 
remove the heat-treated properties.

4.  Use short grinding times and cool with water or some 

type of liquid coolant.

6.  Small imperfections such as nicks and burrs on

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).
