OPERATION
4.7 RaISE EXTENSIoN TRaY bEFoRE
ToWING
Raise the extension tray to an upright position before
towing the machine. Secure with the fastener located near
the top of the chute.
If your model is equipped with a safety bar, once the
extension tray is in an upright position, push the safety bar
down to lock the bar. To unlock, lower the extension tray
and push in the safety bar.
4.6 FEED RoLLER SpEED CoNTRoL
With the feed roller speed control the operator can adjust
the speed of the feed roller, allowing the operator to have
better control of how material is fed into the chipper.
It is recommended that the feed roller operate at a faster
rate for smaller branches and at a slower rate for larger
branches.
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).
4.5 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.
