SAFETY PRECAUTIONS
Understand that your safety and the safety of other persons is measured by how you service and operate
this backhoe. Know the position and operations of all controls before you try 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.
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 in persons falling o 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’s cylinder 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 o of slopes too steep for safe
operation.
Shift down before you start up or down before you start up or down a hill with a heavy load.
Avoid “free wheeling”.
Travel speed should be such that complete control and machine stability is maintained at all times. Where
possible, avoid operating 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 can have sucient force to penetrate
the
skin and cause infection or other injured by leaking fluid, 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.
Contact with overhead power lines can cause severe electrical burn or death from the 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 the tractor brakes cautiously. A loaded attachment in the raised position alters the center of gravity
location of the machine and increase the possibility of mishaps.
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
drop, or attachments to dump, causing severe injury.
Make sure all parked backhoes 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 at all times.
CAUTION
This safety alert symbol indicates important safety messages in this manual.
When you see this symbol, carefully read the message that flows and be alert to
the possibility of personal injury or death.

INITIAL BACKHOE OPERATION
Before operating the backhoe, fully raise and lower the boom, arm, swing and stabilize 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 of time.
COLD WEATHER OPERATION
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 up to operating temperatures.
CAUTION
Operate controls only when seated in the operator’s seat.
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.
Before disconnecting hydraulic lines, relieve all hydraulic pressure. Escaping hydraulic oil under
pressure can have sucient force to penetrate the skin causing serious personal injury. If inured by
escaping hydraulic oil, seek medical attention immediately.
Do not operate the backhoe if the fittings are leaking or if the hoses are damaged. A sudden line burst
would cause the boom, or dipperstick bucket to drop suddenly, causing damage to the tractor or
backhoe or injury to personnel.
