GENERAL OPERATION

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 counter-bal-

ance tractor at all times.

20% of the total tractor,

loader and backhoe weight

must be on the tractor

front axle.

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.
