(1) PERFORM MORE FREQUENTLY UNDER EXTREMELY DUSTY CONDITIONS.
(2) 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 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.
