BACKHOE OPERATION BE-BKxx
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 sufficient 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.
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.
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
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.
CAUTION
Operate controls only when seated in the operator’s seat.
