The chipping blades should clear the anvil by 1/16 inch to
1/8 inch. Check the clearance every 8 hours of operation
and adjust if needed. The chipping anvil is reversible. All
four sides of the anvil can be used for chipping.
To adjust the anvil:
The condition of the hydraulic drive belt should be checked
annually, or after every 25 hours of operation. Replace
the belt if it is cracked, worn, frayed, or stretched.

The diesel engine is tested before shipping. In order to test
the equipment the fluid levels are filled. However, before
starting the machine, and every time the engine is started
thereafter, be sure to check the coolant level. If the level
is low, add fluid.
Refer to the engine owner’s manual for coolant information
and maintenance.
