OPERATION
WARNING
Please read and follow all safety instructions in this
manual. Failure to operate the chipper in accordance
with the safety instructions MAY RESULT IN PERSONAL
INJURY!
4.1 STARTING AND OPERATING CHIPPER
Read and understand all safety warnings and chipping 1.
guidelines contained in this manual before proceeding.
Connect PTO driveline to tractor as described in Sec. 2.
2.4.
Adjust three-point top link so the chipper sits level.3.
Start tractor engine and engage PTO (refer to trac-4.
tor owners manual). Increase engine speed to rated
PTO RPM.
Engage the hydraulic feed by moving the hydraulic 5.
feed control arm. The control arm has four positions:
Reverse, Forward, Stop, and Reverse.
Feed branches up to ve inches in diameter into the 6.
chipper.
Reverse the feed by moving the control arm to reverse 7.
position if the chipper jams. Remove the branch and
rotate it before reinserting it into the chute.
Adjust the speed of the feed roller, if necessary, with 8.
the ow control knob.
DANGER
Do not inspect or work on PTO drive area without rst
disengaging PTO and shutting off tractor engine.
4.2 STOPPING THE CHIPPER
1. Move tractor throttle to SLOW position.
2. Disengage PTO lever and shut off tractor engine.
3. Allow machine to come to a complete stop.
NOTE
The heavy rotor will continue to turn for some time after
the engine or tractor has been shut off. You can tell
that the rotor has stopped when no noise or machine
vibration is present. Inserting a branch into the chipper
chute to contact the blades will slow the rotor and
shorten stopping time.
4.3 CHIPPING GUIDELINES
WARNING
Due to the aggressiveness of the machines chipping
capacity, do not attempt to hold on to material intended
for chipping once it has been placed in the chute.
This chipper is designed to chip a variety of materials into
a more readily decomposing or handled condition. The
following guidelines will help you get started.
Be sure the unit is at full operating speed before you 1.
start to chip material.
Select limbs that are up to 5 inches in diameter. Trim 2.
side branches that cannot be bent enough to feed into
the chipper chute. Small diameter branches can be
held together in a bundle and fed in simultaneously.
Feed brush from the side of the chute, rather than 3.
from the front. Then, step aside to avoid being hit by
the brush moving into the chipper.
Never lean over the chute to push objects into the 4.
cutting device. Use a push stick or brush paddle.
Never use shovels or forks to push brush. They can 5.
go through the chipper, are expensive to replace, and
cause major damage. In addition, metal pieces can
be shot back like shrapnel to injure or kill the operator
or bystanders.
Never push brush into the feed chute with your feet.6.
Engage the hydraulic feed by moving the control 7.
arm.
Place limb, butt end first, into the chipper chute until 8.
it contacts the hydraulic feed roller and is drawn into
the chipper blades. The actual feed rate of the limb
into the chipper will depend on the type of material fed
and the sharpness of the cutting blades.
If the chipper jams, reverse the feed by moving the 9.
control arm in the reverse direction. Remove the
branch and rotate it before reinserting it into the chute.
Alternately insert and retract the limb or insert continuously at a rate that will not kill the engine.
Chipping dead, dry material will create heat and dull 10.
the chipping blades quickly. Alternate greener material
with dry material to lubricate the chipping blades for
longer life and better performance. When the chipping
blades become dull, they will require sharpening. Refer to the Service and Maintenance section for more
information.

As the Chipper Limited Warranty states, failure by the Owner to perform normal maintenance will void
the machine's warranty. The aggressive, high-speed nature of chipping REQUIRES THE OWNER TO
PERFORM THE ABOVE LISTED NORMAL MAINTENANCE. Special consideration to maintain and re-torque
the CHIPPER ANVIL, CHIPPER BLADES, AND ALL INTERNAL AND EXTERNAL NUTS AND BOLTS is the
sole responsibility of the Owner. Failure by the Owner to do so shall be cause for denial of warranty.
5.2 WHEN TO SHARPEN BLADES
Poor chipping performance is usually a result of dull
chipping blades. It is recommended the blades be
sharpened every 5-15 hours of chipper operation. If your
chipper's performance has decreased, the following
symptoms indicate the blades must be sharpened:
10
5 INCH CHIpper
1. Severe vibration when feeding material into the chipper.
2. Small diameter branches do not self-feed.
3. Chips discharge unevenly or have stringy tails–especially when chipping green branches.
Page 15
5.3 REMOVING CHIPPER BLADES
WARNING
Before inspecting or servicing any part of the machine,
shut off the engine, and make sure all moving parts have
come to a complete stop. The chipping blades are sharp!
Use care when working on machine to avoid injury.
To remove the chipping blades for sharpening:
Remove the one 3/8 inch retaining bolt holding the ac-1.
cess cover to main frame assembly (see Fig. 5.1).
SERVICE AND MAINTENANCE
Figure 5.2 Sharpening the blades
5.5 SETTING BLADE CLEARANCE
The chipping blades should clear the chipper anvil (located
directly under the chipper chute) by 1/16 inch to 1/8 inch.
To adjust the blade clearance, proceed as follows:
Figure 5.1 Access bolt
Tilt access cover over to allow rotor access. Rotate 2.
the rotor so that the bolts holding a chipping blade are
most accessible.
Remove the two hex bolts holding the chipper blade. 3.
Repeat for all four chipper blades. 4.
5.4 SHARPENING CHIPPER BLADES
The four chipping blades have two edges per blade and
can be reversed one time each before sharpening (see
Figure 5.2). Remove and reverse the chipping blades if
both sides have not been used. Reinstall chipping blades
and proceed with chipping.
Before you sharpen the chipping blades, check for
permanent damage. Replace the blade if:
1. The blade is cracked (especially around the bolt holes)
or the edges are too deeply chipped to be ground
smooth.
2. The base of the cutting edge is worn or has been re-sharpened so that it is too close to the rotor chipping slot.
1. Lift rotor access cover and expose rotor. Loosen the
two 1/2 inch bolts that hold the chipper anvil to the
frame.
2. Measure the amount of clearance between chipping
blade and chipper anvil from inside of housing. The
gap should be 1/16" to 1/8".
3. Adjust inward or outward to desired measurement.
Use the nuts on the adjustment bolt (See Fig. 5.3).
4. Tighten bolts on chipping block to 75 ft. lbs. and resume
operation.
Remove the two bolts holding the anvil and use one of the
other three edges if the chipper anvil edge is damaged or
worn unevenly. Adjust for correct measurement.
If blades need sharpening, grind the angled edge of the
chipping blade to 45 degrees. Grind the blades on a slowspeed wet grinder if possible, or have them sharpened
by a professional. If you use a bench grinder, be careful
when grinding so that the blade material does not get too
hot and change color–this will remove the blade's special
heat treated properties. Use short grinding times and cool
with water. Try to remove an equal amount off each blade
to maintain balance. Reinstall.

HYDRAULIC
FILTER
5.10 FILLING HYDRAULIC FLUID
CAUTION
Handle pressurized hydraulic uid carefully. Escaping
pressurized hydraulic uid can have sufcient force to
penetrate your skin causing serious injury. This uid
may also be hot enough to burn. Serious infection or
reactions can develop if proper medical treatment is
not administered immediately.
Check the reservoir daily for proper fluid level, the
presence of water (noted by a cloudy to milky appearance,
or free water in bottom of reservoir), and rancid uid odor
(excessive heat). The hydraulic pump normally does not
require regular uid changes.
Premium hydraulic uids containing high quality rust,
oxidation, and foam inhibitors are required. These include
premium turbine oils, API CD engine oils per SAE J183,
M2C33F or G automatic transmission fluids meeting
Allison C-3 or Caterpillar TO-2. and certain specialty
agricultural tractor uids.
System pressure is controlled by the hydraulic control
valve, which is set at 2500 PSI.
5.11 CHANGING HYDRAULIC OIL FILTER
The hydraulic oil lter should be changed after the rst
50 hours and every 200 hours thereafter or at annual
intervals. The uid and lter should be changed and
system cleaned if the uid becomes contaminated with
foreign matter (water, dirt, grease, etc.) or if the uid has
been subjected to temperature levels greater than the
maximum recommended.
The lter is located underneath the hydraulic reservoir.
To change the hydraulic oil lter:
Using an oil filter wrench, unscrew the filter.1.
Once the filter becomes loose, turn it out the rest of 2.
the way with your hand.
Properly discard old filter.3.
Lube the rubber seal on the new filter (PN 16588) with 4.
clean hydraulic oil.
Install the filter onto the threaded pipe. Turn with your 5.
hand until the filter is finger tight.
Turn, by hand, another 1/2 turn.6.
Check hydraulic oil level and fill if necessary.7.
In the unlikely event the the oil is completely drained
from the hydraulic system, oil must be added and any air
bubbles must be purged from the system. To do this:
1. Make sure all system components (reservoir, ttings,
etc.) are clean before starting the hydrostatic pump.
2. Fill the reservoir with recommended hydraulic uid.
Filter uid before lling the reservoir.
3. Fill the inlet line leading from the reservoir to the hy-
draulic pump before start-up. Loosen the tting on the
pump inlet line until oil bleeds out.
4. Start the engine and run at the lowest possible
RPM.
5. The oil level in the reservoir drops and bubbles may
appear in the uid as air is purged from the unit. Rell
the reservoir as necessary.
6. Run the unit and move the control arm in both directions for several minutes until any remaining air is
purged from the unit. Rell the reservoir as necessary.
7. Check to ensure the feed roller stops when the control
arm is in the neutral position.
CAUTION
Hydraulic systems contain uid under high pressure.
Never check for leaks with your hands. Relieve
pressure before disconnecting any hydraulic lines.
8. Shut down the engine or disengage PTO, check for
and correct any uid leaks, and check the reservoir
level. Add uid if necessary.

5.12 PROGRAMMING THE OPTIONAL
HYDRAULIC FEED SENSOR (LOFA)
Some models may have the optional Lofa hydraulic feed
sensor installed. To reset the Lofa program, refer to the
instructions below.
Hold down the "S" button while turning the engine key to
the "on" position until "L" starts to ash on the LCD.
STEP 2. ENTER LOW RPM (L=LOW)
The low setting is the RPM speed where the feed roller
stops. The "up" arrow increases the RPM setting, while
the "down" arrow decreases the RPM setting. Setting the
speed lower causes the engine to lug down more before
the feed roller stops.
1. Hold the appropriate (either up or down) arrow until
1400 RPM is displayed.
2. Push the "S" button once to save.
NOTE: Do not choose a setting equal to or below zero.
1. Hold the appropriate (either up or down) arrow until
1425 RPM is displayed.
2. Push the "S" button once to save.
STEP 6. ENTER NUMBER OF POLES
(IPU = NUMBER OF POLES)
The number of poles indicates the number of speed pickup
devices.
1. Hold the appropriate (either up or down) arrow until
one (1) is displayed.
2. Push the "S" button to save.
RESETTING DAILY HOUR METER (OPTIONAL)
The feed sensor is equipped with an hour meter to track
hour usage. The hours will continue to accumulate until
reset by the operator.
To reset the hour meter:
Stop the engine and make sure the chipper blades and 1.
all moving parts are completely stopped.
Turn key switch to "ON" to energize the feed sensor.2.
Push the "S" button until Day ashes on the LCD 3.
display.
Depress the "S" button for ve seconds and release.4.
Push and hold down the "S" button for an additional 13 5.
seconds until daily hours are reset to zero.
STEP 3. ENTER NORMAL RPM (N=NORMAL)
The normal setting is the RPM at which the chipper rotor
usually turns.
1. Hold the appropriate (either up or down) arrow until
1675 RPM is displayed.
2. Push the "S" button once to save.
STEP 4. ENTER HIGH RPM (H=HIGH)
The high setting is not needed with this application.
1. Set to zero to deactivate.
2. Push the "S" button once with zero displayed to
save.
STEP 5. ENTER RETURN RPM
(RET = RETURN)
The return setting is the RPM speed where the feed roller
restarts. The feed roller should restart before the rotor
reaches "normal" RPM to maximize chipper efciency.
Setting the speed higher allows the engine to recover more
before the feed roller restarts.
