2. The controller also has a “try again” feature. The control-
ler monitors the hydraulic pressure of the feed roller. If it
senses the level is too high (the feed roller becomes ob-
structed) the controller will reverse the feed roller , remov-
ing the material trying to be chipped. The controller will
then engage the roller into the forward position and try to
feed the material again. If this cycle continues, remove
the obstruction manually. Trim or reposition material if
necessary.

Operation
Allow the machine to come to complete stop before in-
spection or servicing.
WARNING
Handle fuel with care. Always use an approved container
and fill tank outdoors.
WARNING
Move machine to a clear, level area. Do not operate in
the vicinity of bystanders.
CAUTION
A pre-programmed hydraulic feed control equips the Bear
Cat chipper. The controller serves a variety of functions
including monitoring chipper rotor RPM, controlling the feed
roller, and providing routine maintenance alerts. The controller
has an on/off feature located below the control panel. If the
controller becomes damaged, the chipper will still run with
the controller shut off, however all of the controller functions
will be disabled. The control arm will control the feed roller.
The controller is positioned under the control panel.
The controller functions are further detailed below:
1. The controller operates the feed roller. The controller moni-
tors the RPMs of the chipper rotor and if it drops below
the preset range the feed roller stops. When the RPMs
reach an acceptable level, the feed roller will reengage.

NOTE
The Murphy switch system will shut the engine off if
the oil pressure is too low or if the engine temperature
is too high. If the engine will not run or shuts off for
these reasons, consult your local dealer.
