(1) PERFORM MORE FREQUENTLY WHEN CHIPPING DRY OR DIRTY WOOD.
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 consider-
ation 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.
When working on the disk assembly, use the lock
mechanism at all times (Figure 5.1). Follow the steps below
to install the disk lock:
1. Rotate the disk 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.
