4 OPERATION
Move machine to a clear, level area outdoors before
starting. Do not operate in the vicinity of bystanders.
Make sure cutting chamber is empty before starting.
WARNING
Before operating your machine, be sure you read
and understand all safety, controls and operating
instructions in this owner’s manual and on your
machine. Failure to follow these instructions can result
in serious injury or property damage.
WARNING
As with any other piece of outdoor equipment, getting the
feel for how your machine operates and getting to know
the best techniques for particular jobs are important to
overall good performance.
CHIPPING OPERATION
The chipping operation takes place in the middle of
the machine, where hardened steel chipper blades are
mounted on a rotating rotor assembly. Material fed into
the chipper chute is sliced into small chips and propelled
out through a discharge tube.
4.1 STARTING THE CHIPPER
1. Connect PTO driveline to tractor as described in
Section 2.4.
2. Adjust three-point top link so the chipper sits level.
3. Start tractor engine and engage PTO (refer to tractor
owner’s manual). Increase engine speed to rated
PTO RPM.
Read and follow all safety instructions in this manual.
Failure to operate the machine in accordance with
the safety instructions MAY RESULT IN PERSONAL
INJURY!
WARNING
The machine chips a variety of materials into a more
readily decomposed or handled condition. The following
guidelines will help you get started.
1. Gradually increase engine speed to rated PTO
RPM. When the controller light is steady green the
engine speed is high enough to begin to chip.
2. ALWAYS run engine at rated PTO RPM before
starting to chip material.
3. Engage the hydraulic feed by pushing the forward
button from the Chipping Screen (see Section 4.7 for
more details on utilizing the Digital Display Controller).
4. If the chipper rotor slows, the feed roller will stop
automatically to process backed up material. Feed
material more evenly.
5. If the chipper jams, the feed roller will reverse
momentarily to remove the branch. Once the branch
is removed, rotate it before reinserting into the
chute. Alternately insert and retract the limb or insert
continuously at a rate that will not kill the engine.
6. Sharpen the chipping blades periodically. Check
the sharpness of the blades every 5-15 hours. Refer to
the Service and Maintenance section for sharpening
instructions.
If forward and reverse feed positions are reversed
when you power up the machine, you may have
plugged the connectors into the wrong plug.
NOTE
Do not inspect or work on PTO drive area without rst
disengaging PTO and shutting o󰀨 tractor. Allow all
moving parts to come to a complete stop.
WARNING
1. Move tractor throttle to slowest position.
2. Disengage PTO lever and shut o󰀨 tractor engine.
3. Allow machine to come to a complete stop.
The rotor will continue to turn for some time after the
engine has been shut o󰀨. Make sure rotor has stopped
completely before inspecting or servicing machine.
NOTE

ENGLISH
OPERATION
7. Limbs fed in to the chipper chute must be 9 inches
(23 cm) in diameter or less. Trim side branches that
cannot be bent enough to feed into the chipper chute.
Hold small diameter branches together in a bundle
and feed in simultaneously.
8. Alternate green or fresh cut material with dry
material to lubricate the chipping blades for
longer life and better performance. Chipping dead,
dry material will create heat and dull the chipping
blades quicker.
9. ALWAYS feed brush from the side of the chipper
chute, rather than from the front. Step aside to avoid
being hit by the brush moving into the chipper.
10. ALWAYS place limb, butt end rst, into the
chipper chute until it contacts the chipper blades.
The actual feed rate of the limb into the chipper will
depend on the type of material fed and sharpness of
the cutting blades.
11. NEVER use the belt engagement to clear a
plugged rotor. This may cause belt damage. Refer
to the instructions for clearing a plugged rotor in the
Service and Maintenance section.
12. NEVER attempt to clear a plugged rotor or discharge
with the engine running. ALWAYS shut engine
OFF and remove the PTO shaft from tractor before
servicing any part of this machine.
13. NEVER attempt to chip pieces of metal, rock, bottles,
cans or other foreign objects.
●Never lean over the chipper chute to push objects
into the cutting device. Use a push stick or brush
paddle.
●Never use shovels or forks to feed brush. They
can cause extensive damage if they contact the
blades. In addition, metal pieces can be ejected
from the chipper chute and cause serious injury
or death.
●Never feed brush into the chute with your feet.
●Never use hands or feet to clear materials that
build up in the chute.
CAUTION
●Obtain and wear safety glasses at all times when
operating the machine.
● Do not wear loose tting clothing.
●The operator should always wear heavy boots,
gloves, pants and a long-sleeved shirt.
●Use common sense and practice safety to protect
yourself from branches, sharp objects, and other
harmful objects.
CAUTION
To prevent personal injury or property damage: shut
o󰀨 engine and make sure that all moving parts have
come to a complete stop before servicing, adjusting,
or repairing machine.
WARNING
Raise the extension tray to an upright position before
towing the machine. Secure with latch.
This machine is equipped with a ow 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 ine󰀩cient operation.
Recommended Procedure: Turn the ow control knob
fully clockwise to bring the feed roller to a stop. Turn the
ow control knob counter clockwise two full turns and
begin feeding material into the chipper. Adjust as needed.

NOTE
Consult the Controller Manual (P/N 71983-00) for
more information on using the Diagnostics screen to
help troubleshoot the chipper control system.
NOTE
This machine is equipped with a Digital Display Controller
(DDC). The DDC monitors the chipper rotor RPM and
regulates the feed roller.
When chipper rotor RPM drops too low, the feed roller
is stopped automatically to allow the chipper rotor to
process material.
When the chipper rotor 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.
This cycle will continue if the piece is not pulled in by the
feed roller. Remove or reposition the material manually
and activate the forward position.
Remember to sharpen blades when necessary so
material will feed smoothly.
The rotor sensor and safety 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 rotor sensor will ash with every rotation of the
chipper rotor when the clearance is set correctly.

slower for large diameter material and faster for smaller
diameter material.
Below the Feed Roller Speed image is an empty area of
the screen that will ash Check blades/anvil when the
chipper blades or anvil require service.
After servicing the blades and anvil, the service indicator
will need to be reset. See Section 4.7.3 for information on
resetting the service indicators.
Figure 4.2, Chipping Screen
The large indicator in the upper right hand corner and the
text box below it will give one of four indications:
●Flashing Green – The chipping rotor has not achieved
enough RPM to begin chipping. It is not possible to
engage the feed roller in the forward direction when
the indicator is ashing green. The text box below the
indicator will display “RPM Not Met.”
●Solid Green – The chipping rotor has achieved
su󰀩cient RPM to begin chipping. The feed roller can
now be engaged in the forward direction. The text box
below the indicator will display “FORWARD.”
●Solid Red – The knee bar has been activated and the
feed roller is now stopped. The text block below the
indicator will display “Hold Knee Bar Reset.”
The Knee Bar functions as an emergency stop system
for the feed roller to immediately stop the feed roller
system. Occasionally, branches or limbs may contact
the Knee Bar with enough force to activate the Knee
Bar safety circuit. When this occurs the operator will
need to reset the Knee Bar safety system with the
“Knee Bar Reset” button to continue chipping. The
“Knee Bar Reset” button will need to be held for
approximately two seconds to reset the system.
Carefully check to be certain the infeed chute and
feed roller are clear and that it is safe to continue
chipping before resetting the Knee Bar Reset.
●Solid Yellow – There is a fault in the chipper control
system. The text box below the indicator will display
“Go to Diagnostic Screen.”
The buttons to the left and to the right of the Navigation
Button are used to control the feed roller.
The Forward button starts the feed roller turning forward
and feeds material into the chipper.
The Reverse button reverses the direction of the feed
roller and will push the material back toward the operator.
The Stop button stops the feed roller.
The Knee Bar Reset button resets the controller so
Forward and Reverse can be re-engaged after the Knee
Bar safety system has been activated. To re-engage the
feed roller safety system after the Knee Bar safety
system has been activated, the operator must press
and hold the Knee bar Reset button for two seconds.
