14 6 INCH CHIPPER
OPERATION
4.6 CHIppER FEED CoNTRoLLER
The chipper is equipped with a Plus 1 Controller that is
located on the chipper chute. the controller monitors the
chipper rotor RPM and regulates the feed roller.
When chipper Rpm drops below the preset range the
feed roller is stopped automatically to help the chipper
process backed up materials.
When the Rpm is back up to an acceptable level the
feed roller will automatically reengage.
When the hydraulic pressure is too high, (if the feed
roller becomes obstructed) the controller will reverse
the feed roller momentarily to try to remove the material
that wasn't chipped. The controller will then engage
the roller into the forward position and try to feed the
material again.
If this cycle continues, the obstruction will have to be
removed manually, or material to be chipped should
be removed, trimmed, and/or repositioned.
The controller is programmed to flash a series of error
codes.
15 hour Service Code • : See Sec. 7.4.
100 hour Service Code • :See Sec. 7.4.
Normal operating RPM • : Steady green light.
Feed Roller Stop Switch • : Euro Models Only-

The controller comes preprogrammed at the factory. If it
should malfunction, contact your dealer. The controller
will not allow the chipper to operate until it has been
properly programmed.
NoTE
The RPM sensor on the rotor must be flashing or the
controller won’t work. Clearance between the sensor
and the bolt must be between 1/32” and 3/32”. There
