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.
5.2 INSTALLING THE ROTOR LOCK
When working on the rotor assembly, use the lock
mechanism at all times (Figure 5.1). Follow the steps
below to install the rotor lock:
1. Rotate the rotor until the hole on the paddle is aligned
with the hole on the chipper housing (Figure 5.1).
2. Install a punch or screwdriver into the holes.
