12 INCH CHIPPER 13
OPERATION
The chipper is equipped with a pre-programmed feed
controller located next to the control panel. The controller
monitors chipper rotor RpM, controls the feed roller, and
provides routine maintenance alerts. The controller has
an on/off switch located next to the control panel. If the
controller becomes damaged, it can be shut off and the
chipper will still run, however all of the controller functions
will be disabled. The feed roller can be manually controlled
with the control bar located on the feed chute.
the.controller.functions.are.further.detailed.below:
The controller monitors the RpM of the chipper rotor. If
the RpM drops below the preset range, the feed roller
is stopped. when the RpM reach an acceptable level,
the feed roller is reengaged.
The controller also has a “try again” feature. If the
hydraulic pressure of the feed roller is too high (if the
feed roller becomes obstructed) the controller will re-
verse the feed roller, removing the unchipped material.
The controller will then reengage the roller forward and
try to feed the material again. If this cycle continues,
remove the obstruction manually. Trim or reposition
material if necessary.
Lights on the controller give the following information:
Error light will flash 10 times every 100 hours
of operation upon startup to indicate the en-
gine oil should be changed.
Error light will flash 5 times every 15 hours of
operation upon startup to indicate the chipper
blades should be sharpened.
Steady power light indicates controller operat-
ing normally, blinking power light indicates low
or no power to the controller.
To reset service alerts, locate the light green wire in
the engine compartment next to the hour meter. Con-
nect the green wire to the red wire connector for five
seconds.
