OWNER'S WARRANTY RESPONSIBILITIES:
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

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 [email protected].
GENERAL 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 certication.
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

10) Add-on or modied parts that are not exempted by the EPA may not
be used. The use of any non-exempted add-on or modied 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

1 SAFETY
Indicates an imminently hazardous situation that, if not
avoided, will result in death or serious injury.
DANGER
1.1 SAFETY ALERT SYMBOL
1.2 EMISSION INFORMATION
Indicates a potentially hazardous situation that, if not
avoided, could result in death or serious injury.
WARNING
Indicates a potentially hazardous situation that, if not
avoided, may result in minor or moderate injury.
CAUTION
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.
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 e󰀨ective
working order.
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 mu󰀪er in continuous e󰀨ective 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 specic information
about which regulations apply in your area.
The standard mu󰀪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.
1.3 BEFORE OPERATING

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 on the front 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 ENGINE
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 engine oil level before starting.
2. Place the throttle control midway between the SLOW
and FAST positions. Place the choke control into the
CHOKE position.
3. Place the chipper engagement lever in the START
position.
4. Use key switch to start the engine.
5. Move the choke to the RUN position.
4.2 OPERATING THE CHIPPER
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 signicant belt squealing and
damage.
Engaging belt while engine is running at high RPM
can also damage vital drive components of the
chipper.
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.
●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
necessary for restart of a warm engine. If it is needed,
return choke to the OFF position once the engine
starts.

ENGLISH
OPERATION
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
4.3 CHIPPER OPERATION GUIDELINES
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 until full throttle
is achieved. When the controller light is steady green
the engine speed is high enough to begin to chip.
2. ALWAYS run engine at full operating speed 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.
7. Limbs fed in to the chipper chute must be 6 inches
(15 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 spark plug wire 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

14 6 INCH CHIPPER
OPERATION
4.5 FEED ROLLER SPEED CONTROL
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.
4.6 CHIPPER FEED CONTROLLER
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 may continue for 10 cycles before staying in
the reverse position. 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 sensor will ash with every rotation of the chipper
rotor when the clearance is set correctly.
NOTE
4.7 USING THE DIGITAL DISPLAY
CONTROLLER
The feed roller FORWARD and REVERSE functions are
controlled by the controller. In addition to the feed roller
control functions, the controller also provides service
reminders, onboard diagnostics, operating instructions,
troubleshooting help and language selection.
4.7.1 MAIN MENU
After turning the key to the ON position, the ECHO Bear
Cat logo will be displayed followed by the screen shown
in Figure 4.1.
The model number of the chipper is displayed in the upper
right hand corner. The model number shown should match
the model of the chipper. If it does not, contact ECHO Bear
Cat Service at 1-866-625-4520 for help.
A scannable QR code is located in the lower left corner. It
will lead you to the ECHO Bear Cat website where owner’s
and parts manuals can be viewed and downloaded.
Battery Voltage is displayed in the upper left hand corner.
4.4 SLOWING AND STOPPING THE
CHIPPER ROTOR 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 o󰀨.
TO PROPERLY SLOW DOWN AND STOP
THE ROTOR 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 o󰀨 the ignition switch.
4. Allow rotor to come to a complete stop.
5. Once the engine is o󰀨 and the rotor has completely
stopped, the belt can be disengaged by moving the
belt engagement handle back to the START position.
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
