SAFETY PRECAUTIONS
Before starting the engine of your tractor,
make sure all operation controls are in park
lock or neutral position.
Stop the backhoe arms gradually when lowering
or lifting loads.
- 4 -
Before applying hydraulic pressure, make sure
all hydraulic connections are tight and
components are in good condition.
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.
Equip your tractor with a ROPS cab or frame
for your protection. See your tractor operator's
manual for correct seat belt usage.
Travel speed should be such that complete
control and machine stability is 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.
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.
Never use your hand to check for suspected
leaks under pressure. Use a piece of cardbord
or wood for this purpose. Escaping hydraulic oil
or diesel fuel leaking under pressure can have
have sufficient force to penetrate the skin and
cause infection or other injured by leaking fluid,
seek medical attention immediately.
Before leaving the tractor, stop the engine,
put all controls in neutral, engage the parking
brake and remove the key from the ignition.
To prevent personal injury, relieve all pressure
before disconnecting fluid lines.

Stay off of slopes too steep for safe operation.
Shift down before you start up or down a hill
with a heavy load. Avoid "free wheeling"
Operate controls only when seated in the
operator's seat.

SAFETY
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.
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.
Do not stand, walk or work under a raised
backhoe or attachment unless it is securely
blocked or held in position. Accidental
movement of a control lever or leak in the
hydraulic system could cause the backhoe to

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

Precautionary Notes
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.
- 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.
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.
- Read and understand this manual to avoid
accidents.
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.

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

seated in the backhoe operator's seat.
- Do not allow riders other than the operator
to be on the tractor while operating.
- Keep all assistants out of area of operation.
- Do not operate rapidly.
Use tractor engine speed that your experience
permits. At first set PTO RPM of the tractor to
slow.
Do not use the boom, dipperstick, swing and

mainframe to drop suddenly, causing damage
to the tractor or backhoe or injury to personnel.
Practice quickly turning off the engine or
stopping the backhoe immediately in case of
an emergency situation.
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.

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.
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.
Also, lock the swing and boom while tractor is
moving and storing for an extended period of
time.
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.
For smooth operation in cold weather, let the
tractor warm up. Slowly cycle all of 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.
