During the first few hours of use, avoid hitting
stones as much as possible to allow the carbide
teeth to wear slightly. This can be done by keeping
the rotor above ground level. Brand new carbide
tips are razor sharp and can chip and shatter
easily when they hit hard objects. Once the razor
sharpness has worn away, the tips do not chip as
easily. Observing these precautions will extend
the life of the carbide teeth and reduce operating
expenses.
4�7 Carbide Teeth Break-In
Before starting, stand to side of stump grinder and
look at center point on bottom of rotor, this will
appear different from the excavator seat and can
be very deceiving.
Operate all functions in an open area with
excavator in idle to get a good feel for the controls,
do not expect to get first stump done fast.
Run throttle only at half speed for first time users.
