DANGER
1.1 SAFETY ALERT SYMBOL
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.
Federal, state, and local laws may prohibit the operation
of 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 arrestor 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). If operating your power
equipment in a󰀨ected areas, it must be equipped with a
spark arrestor in continuous e󰀨ective working order. The
spark arrestor 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 federal, state, and local laws may subject him or her
to nes and/or other penalties. 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 spark
arrestor capable. Spark arrestors require regular
maintenance. See the Service & Maintenance section of
this manual for more information.
Contact local re authorities for laws or regulations
regarding re prevention requirements.

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 in the middle 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.
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.
5. Move the choke to the RUN position.
●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
The chipper base must always be locked in place.
Failure to do so may result in machine vibration,
serious bodily injury or death.
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!
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 8"
(20.3 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

16 9 INCH TURNTABLE 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 will continue if the piece is not pulled in by the
feed roller. 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 rotor 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 Crary 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

Cat Service at 888-625-4520 for help.
A scannable QR code is located in the lower left corner. It
will lead you to the Crary Bear Cat website where owner’s
and parts manuals can be viewed and downloaded.
Battery Voltage is displayed in the upper left hand corner.
The Main Menu is at the center of the screen. The menu
is navigated by using the up and down keys on the
Navigation Button, located directly below the menu.
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
