ENGLISH
OPERATION
Figure 4.2, Feed Roller Speed Control.
4.8 CHIPPER FEED CONTROLLER
4.9 FEED ROLLER CONTROL BAR
This machine is equipped with a Plus 1 Controller. The
controller monitors the chipper disk RPM and regulates
the feed roller.
When chipper disk RPM drops too low, the feed roller
is stopped automatically to allow the chipper disk to
process material.
When the chipper disk returns to chipping RPM, the
feed roller will automatically reengage.
Try Again Feature: If the feed roller becomes obstructed,
the controller will reverse the feed roller momentarily
to clear the obstruction. The controller will then engage
the feed roller and feed the material again.
If this cycle continues, remove or reposition the material
manually.
Remember to sharpen blades frequently so material
will feed smoothly.
The controller light will flash the following codes (See
Sec. 6 for more information):
•
Normal Operating RPM: Steady green light
indicates engine has reached full RPM.
• Feed Bar Not in STOP: Flashing red light indicates
operator must put feed bar in STOP position.
• Service Code: Flashing amber light is a reminder
to check blade sharpness.
• RPM Too Low: Flashing green light indicates
operator must increase engine RPM before starting
to chip.
• Safety Bar Activated: Steady red light (CE
COMPLIANT models only).
NOTE
The disk sensor and feed roller control bar sensors
must be set to the correct clearance or the chipper will
not operate. Set the clearance to 1/32” (the width of a
credit card). The sensor will flash with every rotation of
the chipper disk when the clearance is set correctly.
The Feed Roller Control Bar is used to manually control
the direction of the feed roller rotation.
• Move the feed roller control bar to FORWARD (F)
when you want the materials to feed into the chipper.
The controller light must be steady green.
• Move the feed roller bar to REVERSE (R) when you
want the chipper push materials back out of the feed
chute.
• Move the feed roller bar to STOP to halt the rotation
of the feed roller.
