As the Limited Warranty states, failure by the Owner to perform normal maintenance will void the machine’s warranty.
The aggressive, high-speed nature of chipping REQUIRES THE OWNER TO PERFORM THE ABOVE LISTED NORMAL
MAINTENANCE. Special consideration to maintain and re-torque the CHIPPER ANVIL, CHIPPER BLADES, AND ALL
INTERNAL AND EXTERNAL NUTS AND BOLTS is the sole responsibility of the Owner. Failure by the Owner to do so shall
be cause for denial of warranty.
Chipping blades are sharp! Use caution when working
on machine to avoid injury.
WARNING
1. Disconnect the hydraulic hoses from the skid steer.
2. Position the discharge chute to the side of the chipper.
3. Remove the two bolts on the chipper blade access
cover.
4. Tip the chute and housing away from the chipper to
expose the rotor and the blades.
5.2 REMOVING THE BLADES
5. Use a pry bar between two of the fan blades to prevent
the chipper from rotating during blade removal and
installation.
6. Remove the blades making sure not to slip the wrench,
the chipper blades are sharp.
7. The chipper blades are reversible. If the blades have
not been reversed, flip the blades 180 degrees and
reinstall.
8. If the chipper blades need to be sharpened refer to
Section 5.4 of the manual.
9. Inspect all components of the chipper for damage and
replace if necessary.
