5.1 MAINTENANCE SCHEDULE

The items listed in this service and maintenance schedule are to be checked, and if necessary, corrective action taken.
This schedule is designed for units operating under normal conditions. If the unit is operating in adverse or severe
conditions, it may be necessary for the items to be checked and serviced more frequently.

(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.

5.2 CHIPPER BLADE MAINTENANCE

Do not tip the machine all the way over on its side when

OPERATOR'S MANUAL
The chipper blades will eventually become dull, making
chipping difficult and adding extra strain on the machine.
CHECK THE SHARPNESS OF THE BLADES EVERY
5 - 15 HOURS OF OPERATION AND SHARPEN AS
NEEDED.
Your blades need to be sharpened if:
Machine vibrates severely when material is fed into the
chipper.
Small diameter branches do not self-feed.
Chips discharge unevenly or have stringy tails,
especially when chipping green branches.
