OPERATION
4.8 chIppER FEEd coNTRoLLER
The chipper is equipped with a pre-programmed feed
controller. the controller is located on the chipper hous-
ing above the chipper chute. the controller serves a va-
riety of functions including monitoring chipper disk RPM,
controlling the feed roller, and providing routine mainte-
nance alerts. The control bar located on the feed chute
will control the feed roller.
The controller functions are further detailed below:
The controller operates the feed roller. The controller 1.
monitors the RPMs of the chipper disk and won't
operate until the engine is at full RPM. If the chipper
disk drops below the normal operating RPM, the feed
roller stops. When the chipper disk returns to the
normal operating RPM, the feed roller will reengage.
The controller also has a “try again” feature. The
2.
controller monitors the hydraulic pressure of the feed
roller. If it senses the level is too high (the feed roller
becomes obstructed) the controller will reverse the feed
roller , removing the material trying to be chipped. The
controller will then engage the roller into the forward
position and try to feed the material again. If this cycle
continues, remove the obstruction manually. Trim or
reposition material if necessary.
The feed controller is programmed to display the

following text messages:
15 hour service Code • : "Change/Service
blades".
100 hour service Code • : "Change engine oil".
normal operating rPM • : "Feed control system
available".
high Pressure • : "Try again feature activiated".
Feed roller stop switch • : "Forward feed
stopped".
- domestic Models: disk rPM too low.
- S & F Models: Disk RPM too low or Safety
bar activated.
SAFETy BAR 4. : S & F models only. If safety bar has
been activated the red lED will light up. Push the reset/
override button to resume forward feed (Figure 4.3).
To overcome false trips of the safety bar by 4.
material being chipped, the reset/override button may
be held in for 5 seconds. To repeat, release button
and hold in again.
NoTE: The RPM sensor on the disk must flash or the
controller won’t work. Clearance between the sensor and
the bolt must be between 1/32” and 3/32”.

opERaTING
Start the chipper engine. Bring the machine to 1/4 1.
operating speed (Section 4.1).
Slowly release engagement handle to engage the drive
2.
belt.
Bring the machine to full throttle.
3.
Engage the hydraulic feed by moving the control bar 4.
as shown in Figure 4.3.
If the chipper jams, reverse the feed by moving the
5.
control bar to the reverse position. remove the branch
and rotate it before reinserting into the chute again.
Figure 4.3 - Control Arm Operation
The feed roller control bar is used to manually control the
rotation of the feed roller.
FORWARD (F) rotation is used to move material into the
feed chute towards the chipper blades.
REVERSE (R) rotation is used to push material out of the
feed chute away from the chipper blades.
STOP is used to halt the rotation of the feed roller.

It is important to bring the engine to full RPM before op-
erating the chipper. The chipper feed controller requires
the chipper disk to turn at full RPM in order to operate.
