Safety
1.1...Safety.alert.Symbol
The Owner/Operator's manual uses this symbol to alert
you of potential hazards. whenever you see this symbol,
read and obey the safety message that follows it. Failure
to obey the safety message could result in personal injury,
death or property damage.
Caution
Indicates an imminently hazardous situation that, if not
avoided, will result in death or serious injury.
WarninG
Indicates a potentially hazardous situation that, if not
avoided, could result in death or serious injury.
DanGer
Indicates a potentially hazardous situation that, if not
avoided, may result in minor or moderate injury.
1.2...emiSSion.information
under California Law and under the laws of several
other states, you are not permitted to operate an internal
combustion engine using hydrocarbon fuels on any forest
covered, brush covered or grass covered land or on land
covered with grain, hay or other ammable agricultural
crops, without an engine spark arrester in continuous effective working order.
The engine on your power equipment, like most outdoor
power equipment, is an
internal combustion engine that burns a hydrocarbon fuel. Therefore,
your power equipment
must be equipped with
a spark arrester mufer in continuous effective working order. The
spark arrester must be attached to the engine exhaust
system in such a manner that ames or heat from the
system will not ignite ammable material.
Failure of the owner/operator of the equipment to comply
with this regulation is a misdemeanor under California law
and may also be a violation of other state and/or federal
regulations, laws, ordinances, or codes. Contact your
local re marshal or forest service for specic information
about which regulations apply in your area.
The standard muffler installed on the engine is not
equipped with a spark arrester. One must be added before using this machine in an area where a spark arrester
is required by law. Contact the local authorities if these
laws apply to you. See your authorized engine dealer for
spark arrester options.

Fuel is highly flammable and its vapors are explosive.
To prevent personal injury or property damage:
Store fuel only in approved containers, in well
ventilated, unoccupied buildings, away from
sparks or flames. Do not fill the fuel tank
while the engine is hot or running. Spilled
fuel could ignite if it comes in contact with hot
parts. Do not start the engine near spilled
fuel. Never use fuel as a cleaning agent.
For best results use only clean, fresh #2 diesel. purchase
fuel in small quantities and store in clean, approved
containers. Do not mix gasoline or alcohol with diesel
fuel. use an additive for cold weather to prevent the fuel
from turning into a gel.

4.8..feeD.Controller
Feed Roller
Control Bar
The chipper is equipped with a pre-programmed feed
controller located next to the control panel. The controller
monitors chipper rotor RpM, controls the feed roller, and
provides routine maintenance alerts. The controller has
an on/off switch located next to the control panel. If the
controller becomes damaged, it can be shut off and the
chipper will still run, however all of the controller functions
will be disabled. The feed roller can be manually controlled
with the control bar located on the feed chute.
the.controller.functions.are.further.detailed.below:
The controller monitors the RpM of the chipper rotor. If
1.
the RpM drops below the preset range, the feed roller
is stopped. when the RpM reach an acceptable level,
the feed roller is reengaged.
The controller also has a “try again” feature. If the
2.
hydraulic pressure of the feed roller is too high (if the
feed roller becomes obstructed) the controller will reverse the feed roller, removing the unchipped material.
The controller will then reengage the roller forward and
try to feed the material again. If this cycle continues,
remove the obstruction manually. Trim or reposition
material if necessary.

5.2..When.to.Sharpen.blaDeS
WarninG
Chipping blades are sharp! use caution when working on
machine to avoid injury. Secure the chipping disk before
inspecting, removing or installing chipper blades.
The chipper blades will eventually become dull, making
chipping difficult and adding extra strain on the machine. It
is recommended that the blades be sharpened every 5 to
15 hours or if your chipper’s performance has decreased.
The following symptoms indicate that the blades need to
be sharpened:
Severe vibration when feeding material into the chipper.
1.
Small diameter branches do not self-feed.
2.
Chips being discharged are small, discharge unevenly,
3.
or have stringy tails, especially when chipping green
branches.
5.3..removinG.the.blaDeS
Raise the knife access cover using the jack (Section
1.
4.6) and secure with the lock pin.
Rotate the disk until a chipper blade is accessible.
2.
5.4..SharpeninG.the.blaDeS
Regrind the angled edge of the chipping blades to 45
1.
degrees (see below).
Never sharpen or grind the mounting surfaces of the
2.
blades. This will cause the edge to roll and the blade will
be damaged, resulting in poor chipping performance.
Make sure some type of fixture is used to correctly hold
3.
the blade at the proper angle.
Be careful when grinding so that the blade does not
4.
become overheated and change color. This will remove
the heat-treated properties.
use short grinding times and cool with water or some
5.
type of liquid coolant.
Remove an equal amount off each blade to maintain
6.
rotor balance.
Small imperfections such as nicks and burrs on the
7.
flat side of the blade will not affect the chipping performance of the machine.
For blades that have been repeatedly sharpened,
8.
ensure that the sharpened surface extends past the
chipping slot opening. If it extends less than 1/16"
above the opening, the blades should be replaced.
3.
4.
5.
Before you sharpen the chipping blades, check for
permanent damage. Replace the blade if:
1.
2.
when necessary, sharpen the blades yourself on a bench
grinder or take them to a professional.
Secure the disk to prevent movement while removing
the chipping blades.
Remove the three 5/8" x 3" bolts and nuts holding the
chipper blade to the disk and remove the blade; repeat
for remaining blades.
Inspect blades to see if cracks or nicks are visible. If
cracks are present, replace the blades. If nicks can not
be removed by sharpening blade, replace the blade.
There are cracks, broken corners or nicks greater than
1/8" (see figure below).
The base of the cutting edge is worn or has been resharpened so that the edge extends less than 1/16"
above the rotor chipping slot.
Both ends of the blade can be sharpened

The quantities shown on the next page are recommended
amounts. Experience will show correct fill amounts due
to wide variances in applications, greasing equipment and
operating conditions. In most cases, it is best to lubricate
in small amounts, under low pressure, until a thin bead of
fresh grease is visible at the seal lip area.

Check air pressure in tires every 50 hours. Fill to the
2.
recommended pSI located on the tire sidewall.
Check and repack wheel bearings with grease every
3.
year.
Care should be taken when greasing bearings to avoid
overfilling. Overfilling can lead to excessive heat and/or
unseating of the seals grease should be introduced
in small amounts and under light pressure. whenever
possible, the bearing should be rotated slowly while
grease is added to ensure equal distribution throughout
the raceways.
note
polyuria and lithium based greases are not compatible.
Mixing the two grease types may lead to premature
failure of the chipper.
note
The use of pneumatic grease equipment is not
recommended unless low pressure is assured.

The tables shown below give correct torque values for various bolts and capscrews. Tighten all bolts to the torques
specied in chart unless otherwise noted. Check tightness of bolts periodically, using this bolt torque chart as a guide.
Fasteners should be replaced with the same grade. Tighten serrated or center-lock nuts to the full torque value. Do
not use these values if a different torque value or tightening procedure is given for a specic application. Torque values
listed are for general use only.
