CAUTION
To avoid the possible injury, observe the follow- ing safety rules BEFORE OPERATING the backhoe:
1.BE SURE area is clear of underground utilities or other hazards.
2.POSITION barricade around work area.
3.PROVIDE adequate front end weight to
4.Keep bystanders a safe distance away.
DIRECTIONS: The terms right, left, front and back shall be determined from the position of the operator when seated in the operating position on the backhoe.
ENGINE SPEED
The speed at which the backhoe operates is partially dependent on engine RPM. Use a moderate engine speed to start and increase it as your experience per- mits. Refer to “SPECIFICATIONS” for hydraulic flow volume requirements. When powering from tractor systems with higher output, reduce engine RPM to obtain acceptable backhoe operating speed.

CONTROLS
The backhoe has two major control levers plus the stabilizer control levers. These controls are located on the control panel directly ahead of the operator. See Figure 2. The following is a list of the controls, with the function of each, reading from left to right.
1.Boom/Swing: Push lever forward, the boom moves down, away from the operator. Pull lever back, the boom moves up, toward the operator.
The Boom/Swing Control Lever has an added “float” function. A detent or stop should be felt when the lever is pushed forward to move the boom down. Pushing the lever forward more will overcome the detent and cause the boom to float, or move down or up freely, depending on the forces acting on it. When the lever is released it should return to the center, neutral posi- tion.
Move lever to the left, the backhoe swings to the left. Move lever to the right, the backhoe swings to the right.
By moving the lever to one of the intermediate posi- tions, the boom can be swung left or right at the same it is being raised or lowered, performing the two oper- ations simultaneously.
SWING LEFT AND LOWER the boom by moving the control lever forward and to the left.
SWING LEFT AND RAISE the boom by moving the control lever back and to the left.
