5 INCH CHIPPER/SHREDDER

ENGLISH

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.

The chipper blades will eventually become dull, making 

chipping difficult and adding extra strain on the machine. 

CHECK THE SHARPNESS OF THE BLADES EVERY 

5-15 HOURS OF OPERATION AND SHARPEN AS 

NEEDED.

 

Your blades need to be sharpened if:

 

Machine vibrates severely when material is fed into 

the chipper.

 

Chips discharge unevenly or have stringy tails, 

especially when chipping green branches.

Before you sharpen the chipping blades, check for 

permanent damage. Replace the blade if:

 

There are cracks, broken corners or nicks greater 

than 1/8" (see below).

 

The base of the cutting edge is worn or has been 

re-sharpened so that it no longer extends past the 

chipping slot (see below).

5.2 CHIPPER BLADES MAINTENANCE

1.  Remove the discharge door by removing the retaining 

bolt securing the discharge door/to the chipper body.

2. 

Remove the two 5/16" × 3/4" bolts and nuts securing 

the discharge screen to the frame. Pull the bottom of 

the discharge screen outward to rotate the screen off 

the lip. 

3.  Remove the access cover on the side of the machine.
4.  Rotate the rotor so the bolts holding the chipper blade 

are accessible.

5.  Remove the two bolts holding the blade to the rotor. 

Repeat for remaining blades.

Chipping blades are sharp! Use caution when working 

on machine to avoid injury.

WARNING

5.3 REMOVING THE BLADES

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 5.1). Use the blade angle gauge 

plate when sharpening the blades to achieve the 

proper angle (see Figure 5.2).

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.
