PTO CHIPPERS 14
OPERATION
4.7 FEED ROLLER SPEED CONTROL
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 (European
models only).
4.6 CHIPPER CONTROLLER
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.
This machine is equipped with a flow control to vary
the speed of the feed roller. This allows the operator to
increase the feed speed when processing smaller material
and lower the speed when handling material close to the
maximum capacity of the machine. It is recommended that
operators start using the machine at the lower limits of the
speed control and slowly increase the speed, according to
the size and hardness of the material being chipped.
While occasional stopping and starting of the feed roller
is normal, frequent stopping and starting of the feed
roller and/or rapid decreases in chipper rotor rpms is an
indication that the feed speed is too high. Continued
operation under such conditions can result in plugging of
the discharge, belt damage, and inefficient operation.
Recommended Procedure:
Turn the flow control knob fully clockwise to bring the
feed roller to a stop. Turn the flow control knob counter
clockwise two full turns and begin feeding material into the
chipper. Adjust as needed.
