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.

DANGER

Indicates an imminently hazardous situation that, if not
avoided, will result in death or serious injury.

The engine on your power equipment, like most outdoor
power equipment, is an internal combustion engine that
burns gasoline or diesel fuel (hydrocarbons). Therefore,
your power equipment must be equipped with a spark
arrester muffl er in continuous effective working order. The
spark arrester must be attached to the engine exhaust
system in such a manner that fl ames or heat from the
system will not ignite fl 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 fi re marshal or forest service for specifi c information
about which regulations apply in your area.

The standard muffl er 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.

4.4 OPERATING THE CHIPPER

WARNING

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!

CAUTION

Obtain and wear safety glasses at all times when operating

the machine.
Do not wear loose fitting 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.

WARNING

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.

The machine chips a variety of materials into a more
readily decomposed or handled condition. The following
guidelines will help you get started.

Run unit at full operating speed1. (2600 RPM) before
starting to chip material.

Limbs fed in to the chipper chute must be 12 inches 2.
(30 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.

Exclude pieces of metal, rocks, bottles, cans, and 3.
other foreign objects when feeding material into the

machine.
Feed brush from the side of the chipper chute,4. rather

than from the front. Step aside to avoid being hit by the
brush moving into the chipper.

Place limb, butt end first, into the chipper chute 5. 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.

Adjust the speed of the feed roller, 6. if necessary , with
the feed roller speed control (see Sec. 4.7).

To prevent excessive banging and slamming 7. on
the top of the chipping chamber that may occur when
feeding larger logs (8" and above), lift the feed roller
with the feed roller lift control (see Sec 4.6).

If the engine slows to where it may stall,8. stop feeding
material and allow the engine to recover. Feed material
more evenly.

If the chipper jams,9. 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.

Do not use the clutch to clear a plugged rotor. 10. This
may cause belt damage. Refer to the instructions for
clearing a plugged rotor in the Service and Maintenance
section.

Alternate greener material with dry material 11. to
lubricate the chipping blades for longer life and better
performance. Chipping dead, dry material will create
heat and dull the chipping blades quickly.

Sharpen the chipping blades periodically. 12. Check
the sharpness of the blades every 5-15 hours. Refer
to the Service and Maintenance section for sharpening
instructions.

4.5 FEED ROLLER CONTROL BAR

Feed Roller Control Bar is used to manually control the

direction of the feed roller rotation.
Move the feed roller bar to FORWARD (F) when you want

the materials to feed into the chipper.
Move the feed roller bar to REVERSE (R) when you want

the chipper push materials back out of the feed chute
(when materials become jammed).

Move the feed roller bar to STOP to halt the rotation of the
feed roller.

OPERATION

4.6 RAISING THE FEED ROLLER

The feed roller lift control is used to raise the feed roller
during operation so that larger logs (over 8 inches) can be
fed into the chipper easier. It is also used to gain access to
the feed roller when servicing the machine. The belt does
not have to be engaged to use the feed roller lift, but the
machine must be running. To raise the feed roller:

Push the feed roller control to the right and hold it until 1.
the feed roller is fully raised.

Secure using the lock up pin located on the roller slide 2.
when servicing the machine. Do not use the lock up pin
when raising the feed roller to accomodate large logs.

Release the feed roller control.3.
T o lower the feed roller , remove the lockup pin (this may 4.

require raising the feed roller slightly), then release the
feed roller control.

NOTE

Using the feed roller lift makes feeding larger logs
(8" and above) easier and prevents the banging and
slamming to the top that can occur.

4.7 FEED ROLLER SPEED CONTROL

The feed roller speed control is used to control the rate at
which material is pulled into the chipper.

When beginning operation, the control should be set in mid
range. Adjust the speed by slightly unscrewing the black
knob and then turning the control. To increase the speed
of the feed roller, move the lever clockwise. To slow the
speed, move the lever counterclockwise. After adjusting,
retighten the knob.

It is recommended that the feed roller operate at a faster
rate for smaller branches and at a slower rate for larger
branches.

the right and pump the handle.

4.9 FEED CONTROLLER

OPERATION

The chipper is equipped
with a pre-programmed
feed controller located
next to the engagement
handle. The controller
monitors chipper rotor
RPM, controls the feed
roller, and provides
routine maintenance
alerts.

The controller functions
are further detailed
below:

The controller 1.
monitors the RPM of the
chipper rotor. If the RPM
drops below the preset
range, the feed roller
is stopped. When the
RPM reach an accept­able level, the feed roller
is reengaged.

ENGLISH

Secure the cover using the lock pin located on the 5.
outside of the chipper housing (see below).

To lower the cover, remove the lock pin and turn the 6.
wing nut located on the jack to the left to release the
hydraulic pressure.

The controller 2.
also has a “try again”

feature. If the 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.

Lights on the controller give the following information:3.

Error light will flash 10 times every 100 hours •
of operation upon startup to indicate the engine
oil should be changed.

Error light will flash 5 times every 15 hours of •
operation upon startup to indicate the chipper
blades should be sharpened.

Secure the knife access cover to the chipper housing 7.
using two 1/2" x 1-14" bolts, nuts and washers.

NOTE

When closing the rotor cover, make sure the bolts are
securely tightened. If they are not, the safety switch
may respond as though the battery is dead.

12 INCH CHIPPER

Steady power light indicates controller operat-•
ing normally , blinking power light indicates low

5.2 CHIPPER BLADE MAINTENANCE

The chipper blades will eventually become dull, making
chipping diffi cult and adding extra strain on the machine.

CHECK THE SHARPNESS OF THE BLADES EVERY
5 - 15 HOURS OF OPERATION AND SHARPEN AS
NEEDED.

Your blades need to be sharpened if:

• Machine vibrates severely when material is fed into the
chipper.

• Small diameter branches do not self-feed.

• Chips discharge unevenly or have stringy tails, espe­cially when chipping green branches.

Before you sharpen the chipping blades, check for
permanent damage. Replace the blade if:

• There are cracks, broken corners or nicks greater than

1/8" (see below).

CRACK
GREATER
THAN 1/8”

BROKEN
CORNER

5.3 REMOVING THE BLADES

Raise the knife access cover using the jack (Section 1.

4.8) and secure with the lock pin.
Rotate the disk until a chipper blade is accessible.2.
Secure the disk to prevent movement while removing 3.

the chipping blades.
Remove the three 5/8" x 3" bolts and nuts holding the 4.

chipper blade to the disk and remove the blade; repeat
for remaining blades.

Inspect blades to see if cracks or nicks are visible. If 5.
cracks are present, replace the blades. If nicks can not
be removed by sharpening blade, replace the blade.

5.4 SHARPENING THE BLADES

The blades can be ground on a bench grinder or by a
professional.

Never sharpen or grind the mounting surfaces of the 1.
blades. This will cause the edge to roll and the blade will
be damaged, resulting in poor chipping performance.

Regrind the angled edge of the chipping blades to 45 2.
degrees. Make sure some type of fixture is used to
correctly hold the blade at the proper angle.

Be careful when grinding so that the blade does not 3.
become overheated and change color. This will remove
the heat-treated properties.

Use short grinding times and cool with water or some 4.
type of liquid coolant.
