14 6 INCH CHIPPER
OPERATION
4.6 CHIppER FEED CoNTRoLLER
The chipper is equipped with a Smart Relay hydraulic feed
controller that is located beneath the control panel. 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. the screen will read
"Forward Feed Stopped."
When the Rpm is back up to an acceptable level the
feed roller will automatically reengage. The screen will
read "Forward Feed Available."
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 screen will read "Try again
feature activated." 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 will display the following service
messages:
"Change/Service blades" every 15 hours, •
"Change engine oil" every 100 hours. •
The controller comes preprogrammed at the factory. If it
should malfunction and the screen reads "No Program
Available," contact your dealer. The controller will not
allow the chipper to operate until it has been properly
programmed.
