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.
