CAUTION
: 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 injured by escaping hydraulic oil, seek medical attention immediately.
CAUTION
: Do not operate the backhoe if the fittings leaking or if the hoses are damaged. A sudden line burst
would cause the boom, or dipper arm bucket to drop suddenly, causing damaged to the tractor or backhoe or injury to
personnel.
6.2 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 level and add as required.
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.
When possible keep cylinders in a retracted position when the backhoe is in use guard against rust and contamination which
may cause damage to the cylinder rods or hydraulic system. Also, lock the swing and boom while backhoe is being
transported and storing for an extended period of time.
6.3 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 to operating temperatures.
CAUTION
: Operate controls only when seated in the operator’s seat with seat belt on.
6.4 BACKHOE HYDRAULIC CONTROLS
The backhoe hydraulic valve features 4 control levers. Refer to the diagram below for backhoe control functions.
“Left” and
“Right” are determined by the direction the operator is facing when seated in the backhoe.
The Diagram is located on the rear of the control valve bracket and is visible when operating the valve.
