MAINTENANCE

4. Note the assembly sequence of the hardware used to secure

the shredder blades and ﬂail blades. Using a 5/8 in. socket,

remove the center bolt. Using a 17mm socket remove the

four bolts to disassemble the shredder blade and ﬂail blade

assembly.

The hardware on this assembly was tightened and torqued during

production and may require the use of an impact wrench to

remove.

5. Inspect the shredder blade (A), ﬂail blades (B), spacers (C),

chipper blades (D) and hardware (nuts, bolts and washers). If

any of the parts show signs of wear and/or damage, replace

them.

6. Reassemble the hammers, blade, spacers, washers, nuts and

bolts. Torque the nuts and bolts to 30-35 ft. lbs.

Chipping Blade Sharpening and Replacement

 WARNING

To avoid injury, perform maintenance on the unit only when the

engine is stopped. Always disconnect the spark plug wire and

fasten it away from the plug before beginning maintenance to

prevent accidental starting of the engine.

The chipping knives should be sharpened or replaced when tree

limbs require extra force to feed into the chipper chute.

The chipping knives may be sharpened at a 30-degree angle

until the distance between the edge of the blade bevel and the

mounting hole is less than 1/16” (1.6mm).
