SAFETY PRECAUTIONS
Understand that your safety and the safety of
other persons are measured by how you service
and operate this backhoe. Know the position
and operations of all controls before you they
to operate. Make sure you check all controls
in all safe area before starting.
▶Read this manual completely and thoroughly
And make sure you understand all controls.
All equipment has a limit Make sure you are
aware of the stability and load characteristics
of this backhoe before you begin operation.
The safety information given in this manual does
not replace any safety codes, insurance needs,
federal, state and local laws. Make sure your
machine has the correct equipment required by
your local laws and regulations.
This safety alert symbol indicates important safety messages in this manual.
When you see this symbol, carefully read the message that follows and
be alert to the possibility of personal injury or death.
SAFETY PRECAUTIONS
Before starting the engine of your tractor, make
sure, all operation controls are in park lock or
neutral position.
Operate controls only when seated in the
operator's seat.
Equip your tractor with a ROPS cab or frame
for your protection. See your tractor operator's
manual for correct seat belt usage.
A frequent cause of personal injury or death is
persons falling off and being run over. Do not
permit others to ride on your tractor. Only one
person, the operator, should be on the machine
when it is in operation.
Before leaving the tractor, stop the engine, put all
controls in neutral, engage the parking brake and
remove the key from the ignition.
When using remote hydraulic tractor valves on
some tractors, the backhoe lift and dump cylinders
will continue moving unless the control levers are
manually returned to neutral, or until relief pressure
is reached at the ends of piston strokes. Observe
the bucket movement and maintain control with
the control levers.
Stop the backhoe arms gradually when lowering
or lifting loads.
Stay off slopes too steep for safe operation.
Shift down before you start up or down a hill
with a heavy load. Avoid "Freewheeling"
Travel speed should be such that complete
control and machine stability are maintained
at all times. Where possible, avoid operation near
ditches, embankments and holes.
Reduce speed when turning, crossing slopes,
and on rough, slick or muddy surfaces.
Never use your hand to check for suspected
leaks under pressure. Use a piece of cardboard
or wood for this purpose. Escaping hydraulic oil
or diesel fuel leaking under pressure has enough
force to penetrate the skin and cause infection or
other injuries by leaking fluid. If this occurs seek
medical attention immediately.
To prevent personal injury, relieve all pressure
before disconnecting fluid lines.
Before applying hydraulic pressure, make sure
all hydraulic connections are tight and
components are in good condition.

5
SAFETY PRECAUTIONS
Contact with overhead power lines can cause severe
electrical burn or death from electrocution.
Make sure there is enough clearance between raised
equipment and overhead power lines.
Add recommended rear tire liquid weight or rear
wheel weights for increased stability.
A backhoe attachment should be transported in a
low position at slow ground speeds. Make turns
slowly and use the tractor brakes cautiously.
A loaded attachment in the raised position alters the
center of gravity location of the machine and
increases the possibility of mishaps.
Make sure all parked backhoe on stands are on a
hard level surface with all safety devices
engaged to prevent backhoe from falling and being
damaged or injuring someone.
When using a backhoe, be alert of bucket, boom
and arm position always.

6
SAFETY DECALS
Safety decal locations
Important: Warning decals are visible when getting on backhoe. Refer to the left and right hands
used in this manual, It's the position of the operator when seated in the operating position of backhoe
Care of safety decals.
1. Keep safety decals clean and free of obstructing material.
2. Clean safety decals with soap and water and dry with a soft cloth.
3. If a component with a safety decal(s) affixed is replaced with a new
part, make sure new safety decal(s) are attached in the same location(s)
as the replaced components.
4. Mount new safety decals by applying on a clean dry surface and pressing
air bubbles to outside edges.

TRACTOR PREPARATION
Caution :
Do not exceed the manufacturer's rating
for maximum gross vehicle weight. Refer to
operator's manual or ROPS serial plate
provided with tractor.
Caution :
Certain specific conditions may not permit
safe use of backhoe at backhoe rating or
may require more careful restricted
operation at the rated load.
▶ROPS system
▶Tractor hydraulic system
Tractor operation in a backhoe application
significantly increase demands on the tractor
hydraulic system. Check the tractor
Hydraulic system fluid level daily. Refer to
your Tractor operator's manual maintenance
section for instructions regarding tractor
hydraulic system maintenance.
Adhere to recommendation in your Tractor
operator's manual concerning hydraulic
fluid and filter specifications, and change intervals.
The tractor must be equipped with an approved
ROPS system to ensure adequate operator's
protection.
Caution :
The tractor/backhoe must only be operated with all safety equipment properly installed.
▶Tire inflation
Front tires must be maintained at the maximum
recommended inflation to maintain normal tire
profile with the added weight of backhoe/material.
Rear tires must be maintained at equal pressure
within the recommended tire inflation range.
Unequal rear tire inflation can prevent backhoe
attachment from contacting the ground across its
full width.
▶Wheel tread settings
Tractor front wheel tread setting must be
restricted to wheel tread spacing recommended
in the tractor operator's manual.

12
BACKHOE OPERATION
Caution :
The tractor/backhoe should only be
operated with all safety equipment properly
installed. Keep assistants or bystanders a safe
distance from the equipment operating area.
▶Precautionary notes
- Check below items before operating for your
safety.
- Read and understand this manual to avoid
accidents.
- Check the hydraulic fitting lines to be
correct and set tightly
- Maintain and repair (If it is needed) the
parts or assemblies, check bolts and pins
to be sure they are positioned tightly.
- Check tractor with the Tractor operator's
manual that it can prepared for operating.
- Warm up and operate the tractor and
backhoe carefully. Purge any air in the
hydraulic lines and cylinders by fully
cycling all cylinders several times.
- Check hydraulic level in the tank. It should
be full (Refer to the Tractor operator's
manual).
- Do not operate the hydraulics when not
seated in the backhoe operator's seat.
- Keep all assistants out of area of operation.
- Do not operate rapidly.
- Do not allow riders other than the operator
to be on the tractor while operating.
▶Important:
Use tractor engine speed that your experience
permits. At first set PTO RPM of the tractor to slow.
Do not use the boom, dipper stick, swing and
stabilizers to lift, push or pull objects. Use only to
maneuver and operate the bucket.
▶Important:
Practice quickly turning off the engine or stopping
the backhoe immediately in case of an emergency.
▶Important:
Do not operate while the rear tractor wheels are off
the ground by stabilizer. It is dangerous to operate
the backhoe while rear wheels are off the ground.
Position vehicle so that the backhoe is as near to the
pile as possible and in such a direction as to
minimize the amount of tractor turning required to
dump.
Keep the unit clean and perform regular service.
Observe safety messages whenever cleaning,
servicing, or lubricating.
▶We urge you to follow this advice
1. Read and understand this manual as well as the
Tractor operator's manual.
2. Remember and observe the safety precautions
brought to your attention in this manual, the
tractor manual and on the machinery itself.
3. Use good common sense in the everyday
operation of this unit.
Safety recommendations can never be all-
inclusive, and you are responsible for
watching out for and avoiding unsafe conditions.
4. Never exceed the limits of a piece of
machinery. If its ability to do a job or to do
so safely is in question, don't try it.
5. Don't hurry the learning process or take the
unit for granted. Ease into it and become
familiar with your new backhoe and tractor.
Caution : When lowering a heavy load, ease
it downward slowly. Never drop a loaded
attachment and "Catch it hydraulically".
Stopping a load after it has gained downward
momentum places undue strain on the unit and may
cause unnecessary damage to the backhoe or tractor
or even worse, personal injury.
Caution : Before disconnecting hydraulic
lines, relieve all hydraulic pressure. Escaping
hydraulic oil under pressure can have
enough force to penetrate the skin causing serious
personal injury. If injured by escaping hydraulic oil
seek medical attention immediately.
Caution : Do not operate the loader if the
fittings are leaking or if the hoses are
damaged. A sudden line burst would cause
the mainframe to drop suddenly, causing damage to
the tractor or loader or injury to personnel.

13
BACKHOE OPERATION
▶Initial backhoe operation
Before operating the backhoe, fully raise and lower
the boom, arm, swing and stabilizers two or three
times. Then raise the bucket above the ground and
cycle the bucket cylinders three times. Lower the
bucket to the ground. Check the tractor hydraulic oil
and the correct oil level.
Caution:
Before leaving the machine, stop the engine,
remove the key, place all controls in neutral,
and either set the parking brake or place tractor in
park as equipped.
Always keep cylinders in a retracted position when
the backhoe is not in use to guard against rust and
contamination which may cause damage to the
cylinder rods or hydraulic system.
Also, lock the swing and boom while tractor is
moving and storing for an extended period.
▶Cold weather operation
For smooth operation in cold weather, let the tractor
warm up. Slowly cycle all the cylinders several times
to warm the oil in the hydraulic system. The backhoe
may operate erratically until the hydraulic oil has
warmed to operating temperatures.
Caution :
Operate controls only when seated in the operator's seat.
