SAFETY
1.1 SAFETY ALERT SYMBOL 1.2 EMISSION INFORMATION
Under California Law and
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 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.
WARNING
Indicates a potentially hazardous situation that, if not
avoided, could result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation that, if not
avoided, may result in minor or moderate 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 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 mufer 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.

OPERATION
As with any other piece of outdoor power equipment,
getting the feel for how your machine operates and
getting to know the best techniques for particular jobs are
important to good overall performance.
Chipping
The chipping takes place in the smaller, side chute. Feed
branches with a diameter no larger than 5 inches into the
chipper chute. Material fed into the chipper chute is sliced
into small chips and propelled out through the discharge
tube.
Shredding
The shredding takes place in the larger, rear chute. Feed
branches and other yard materials no larger than 3/4 inch
in diameter into the shredder chute. Material fed into the
shredder chute is shredded and propelled out through the
discharge tube.
WARNING
Before operating your machine, be sure you read and
understand all safety, controls and operating instructions in
this Owner/Operator's manual and on your machine. Failure
to follow these instructions can result in serious injury or
property damage.
WARNING
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.
4.1 STARTING ENGINE
6. Increase engine RPM to full throttle once belt is
engaged.
For a Cold Engine - gradually return the choke to the OFF
position after the engine starts and warms up.
For a Warm Engine - Use of choke may not be neces-
sary for restart of a warm engine. If it is needed, return
choke to the OFF position once the engine starts.
4.2 OPERATING THE CHIPPER/SHREDDER
After the engine has been started and properly allowed
to warm to an operating temperature, you can begin
operating the chipper. To properly start and operate the
chipper, follow the steps below:
1. AFTER engine is warmed and ready for use, move the
throttle control back to approximately 25% of full throttle.
2. When engine is running at approximately 25% of
full throttle, SLOWLY engage belt by using the belt
engagement lever.
DO NOT engage the belt with engine running at high
RPM.
Engaging belt while engine is running at high
RPM will result in signicant belt squealing and
damage.
Engaging belt while engine is running at high RPM
can also damage vital drive components of the
chipper.
ENGLISH
BEFORE ATTEMPTING TO START THIS MACHINE,
MAKE SURE THE BELT IS DISENGAGED AND THE
HANDLE IS IN THE "START" POSITION.
NEVER ATTEMPT TO START MACHINE WITH THE
DRIVE BELT ENGAGED.
1. Check fuel and engine oil levels before starting.
2. Move the belt engagement lever to START position.
3. Move throttle lever to 1/3 of full throttle. To start a cold
engine, pull the choke ring lever out.
4. Turn key to the START postion. Release the key switch
as soon as the engine starts. Gradually push the choke
ring lever in as the engine warms up.
5. Slowly move belt engagement lever to the CHIPPING
position to engage the rotor.
5 INCH CHIPPER/SHREDDER/BLOWER
3. If the chipper engine stalls while engaging the belt,
return the engagement handle back to the START
position, restart engine, SLIGHTLY increase throttle
and attempt engagement again.
4. Once the belt is engaged, SLOWLY increase throttle
to 100% or full throttle.
5. ALWAYS run the chipper at 100% or full throttle when
chipping material.
4.3 CHIPPER/SHREDDER OPERATION GUIDELINES
1. Limbs fed in to the chipper chute must be 5 inches
12.5 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.
11
WARNING
DO NOT INSERT BRANCHES LARGER
THAN 3/4 INCH INTO SHREDDER OR
MACHINE DAMAGE MAY OCCUR.
2. ALWAYS run engine at full operating speed before
starting to chip material.
3. 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
quickly.
4. 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.
5. ALWAYS place limb, butt end first, 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.
CAUTION
Obtain and wear safety glasses at all times when operat-
ing 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 your-
self from branches, sharp objects, and other harmful
objects.
6. If the engine slows to where it may stall, stop feeding
material and allow the engine to recover. Feed material
more evenly.
7. If the chipper jams, 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.
8. 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.
9. NEVER attempt to clear a plugged rotor or discharge
with the engine running. ALWAYS shut engine OFF
and remove the spark plug wire before servicing any
part of this machine
10. NEVER attempt to chip pieces of metal, rock, bottles,
cans or other foreign objects.
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!
4.4 SLOWING AND STOPPING THE
CHIPPER/SHREDDER DISK AND ENGINE
NEVER disengage the belt as part of the stopping or
shut down process. The belt should remain engaged
during the entire shutdown process.
Leaving the belt engaged is a vital part of proper shutdown and ensures the rotor stops spinning in conjunction with the engine shutting off.
TO PROPERLY SLOW DOWN AND STOP THE DISK
AND ENGINE:
1. WITH THE BELT STILL ENGAGED, SLOWLY move the
throttle to the SLOW position with the belt still engaged.
2. Allow the engine to run at slow idle for 30-60 seconds.
3. Stop the engine by moving the throttle to the STOP
position or turning off the ignition switch.
12
4. Allow disk to come to a complete stop.
5 INCH CHIPPER/SHREDDER/BLOWER
5. Once the engine is off and the disk has completely
stopped, the belt can be disengaged by moving the
belt engagement handle back to the START position.
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.
4.5 OPERATION TIPS
The engine/equipment may be operated during the warm
up period, but it may be necessary to leave the choke partially on until the engine warms up.
OPERATION
ENGLISH
Upon start up, a metallic ticking may occur. This is caused
by the hydraulic lifter Ieakdown during storage. Run the
engine for 5 minutes. The noise will normally cease in
the rst minute. If noise continues, run the engine at midthrottle for 20 minutes. If noise persists, take the engine to
your local authorized Subaru Engine Service Dealer.
If the engine develops sufcient speed to disengage
the starter but does not keep running (a false start), the
engine rotation must be allowed to come to a complete
stop before attempting to restart the engine. If the starter
is engaged while the ywheel is rotating, the starter pinion
and ywheel ring gear may clash resulting in damage to
the starter.
If the starter does not turn the engine over, shut off starter
immediately. Do not make further attempts to start the
engine until the condition is corrected. Do not jump start
using another battery. See your Honda Engine Service
Dealer for service assistance
Do not crank the engine continuously for more than 10
seconds at a time. If the engine does not start, allow a
60-second cool down period between starting attempts.
Failure to follow these guidelines can permanently damage
the starter.
With a new drive belt, the rotor may rotate with the
engagement handle in START position. Within a short
period, the belt will relax and the rotor should disengage.
If the rotor does not disengage even after a short period,
check pulley alignment and idler mechanism or return to
your dealer for service. (See Section 5 for replacing the
drive belt).

5.2 CHIPPER BLADE MAINTENANCE
The chipper blades will eventually become dull, making
chipping difcult 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, espe-
cially 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”
NICK GREATER
THAN 1/8”
5.3 REMOVING THE BLADES
WARNING
The chipping blades are sharp!! Use care when
working on the machine to avoid injury.
1. Loosen and remove the 3/8” carriage bolt securing the
knife access cover.
2. Open the access cover exposing the chipper shredder
compartment.
3. Rotate the rotor so that the bolts holding the chipper
blade are most accessible.
4. Remove the two hex head bolts holding the blade itself.
Repeat for the second blade. The chipping blades have
two edges per blade and can be reversed one time
each before sharpening. If one side has not been used,
remove and reverse the chipping blades.
5.4 SHARPENING THE BLADES
The blades can be ground on a bench grinder or by a
professional.
1. Never sharpen or grind the mounting surfaces of the
blades. This will cause the edge to roll and the blade will
be damaged, resulting in poor chipping performance.
2. Regrind the angled edge of the chipping blades to 45
degrees (see below). Make sure some type of fixture is
used to correctly hold the blade at the proper angle.

4. Use short grinding times and cool with water or some
type of liquid coolant.
5. Remove an equal amount off each blade to maintain
rotor balance.
6. Small imperfections such as nicks and burrs on the flat
side of the blade will not affect the chipping performance
of the machine.
7. For blades that have been repeatedly sharpened,

EPA EMISSION CONTROL WARRANTY STATEMENT
YOUR WARRANTY RIGHTS AND OBLIGATIONS
Crary Industries Inc. is pleased to explain the evaporative emission
control system (EECS) warranty on your 2013 equipment. New
equipment must be designed, built and equipped to meet the EPA’s
stringent anti-smog standards. Crary Industries Inc. must warrant the
EECS on your equipment for the period of time listed below provided
there has been no abuse, neglect or improper maintenance of your
equipment.
Your EECS may include parts such as the fuel tank, fuel lines, fuel
caps, vapor hoses, and clamps.
Where a warrantable condition exists, Crary Industries Inc. will repair
your equipment at no cost to you including diagnosis, parts and labor.
MANUFACTURER’S WARRANTY COVERAGE:
This evaporative emission control system is warranted for two years. If
any evaporative emission-related part on your equipment is defective,
the part will be repaired or replaced by Crary Industries Inc.
OWNER’S WARRANTY RESPONSIBILTIES:
As the equipment owner, you are responsible for performance of the
required maintenance listed in your owner’s manual. Crary Industries
Inc. recommends that you retain all receipts covering maintenance on
your equipment, but Crary Industries Inc. cannot deny warranty solely
for the lack of receipts.
As the equipment owner, you should however be aware that Crary
Industries Inc. may deny you warranty coverage if your equipment or
a part has failed due to abuse, neglect, or improper maintenance or
unapproved modications.
You are responsible for presenting your equipment to Crary Industries
Inc.’s distribution center or service center as soon as the problem
exists. The warranty repairs should be completed in a reasonable
amount of time, not to exceed 30 days. If you have a question regarding
your warranty coverage, you should contact Justin Banyai at 1-701-
282-5520.
GERERAL EMISSIONS WARRANTY COVERAGE:
Crary Industries Inc. warrants to the ultimate purchaser and each
subsequent purchaser that the equipment is:
Designed, built and equipped so as to conform with all applicable
regulations; and
Free from defects in materials and workmanship that cause the failure
of a warranted part to be identical in all material respects to that part as
described in Crary Industries Inc.’s application for certication.
The warranty period begins on the date the equipment is delivered to
an ultimate purchaser or rst placed into service. The warranty period is
two years.
Subject to certain conditions and exclusions as stated below, the
warranty on emission-related parts is as follows:
(1) Any warranted part that is not scheduled for replacement as
required maintenance in the written instructions supplied, is warranted
for the warranty period stated above. If the part fails during the period
of warranty coverage, the part will be repaired or replaced by Crary
Industries Inc. according to subsection (4) below. Any such part
repaired or replaced under warranty will be warranted for the remainder
of the period.
(2) Any warranted part that is scheduled only for regular
inspection in the written instructions supplied is warranted for the
warranty period stated above. Any such part repaired or replaced under
warranty will be warranted for the remaining warranty period.
(3) Any warranted part that is scheduled for replacement as
required maintenance in the written instructions supplied is warranted
for the period of time before the rst scheduled replacement date for
that part. If the part fails before the rst scheduled replacement, the
part will be repaired or replaced by Crary Industries Inc. according
to subsection (4) below. Any such part repaired or replaced under
warranty will be warranted for the remainder of the period prior to the
rst scheduled replacement point for the part.
(4) Repair or replacement of any warranted part under the
warranty provisions herein must be performed at a warranty station at
no charge to the owner.
(5) Notwithstanding the provisions herein, warranty services
or repairs will be provided at all of our distribution centers that are
franchised to service the subject engines or equipment.
(6) The equipment owner will not be charged for diagnostic
labor that is directly associated with diagnosis of a defective, emissionrelated warranted part, provided that such diagnostic work is performed
at a warranty station.
(7) Crary Industries Inc. is liable for damages to other engine or
equipment components proximately caused by a failure under warranty
of any warranted part.
(8) Throughout the equipment warranty period stated above,
Crary Industries Inc. will maintain a supply of warranted parts sufcient
to meet the expected demand for such parts.
(9) Any replacement part may be used in the performance of any
warranty maintenance or repairs and must be provided without charge
to the owner. Such use will not reduce the warranty obligations of Crary
Industries Inc.
(10) Add-on or modied parts that are not exempted by the EPA
may not be used. The use of any non-exempted add-on or modied
parts by the ultimate purchaser will be grounds for disallowing a
warranty claim. Crary Industries Inc. will not be liable to warrant failures
of warranted parts caused by the use of a non-exempted add-on or
modied part.
WARRANTED PARTS:
The repair or replacement of any warranted part otherwise eligible for
warranty coverage may be excluded from such warranty coverage
if Crary Industries Inc. demonstrates that the equipment has been
abused, neglected, or improperly maintained, and that such abuse,
neglect, or improper maintenance was the direct cause of the need for
repair or replacement of the part. That notwithstanding, any adjustment
of a component that has a factory installed, and properly operating,
adjustment limiting device is still eligible for warranty coverage. The
following emission warranty parts are covered:
(1) Fuel Tank
(2) Fuel Cap
(3) Fuel Line
(4) Clamps
(5) Vapor Hose
