2.2 Boom Length Adjustment

2.2.1 Boom Length Zero Adjustment

- Fully retract the boom.

- Until "Boom Length" and "Zero adjustment value" become highlighted on the LCD (Fig. 2.1.1), press the < > key (backward) or the < > key (forward).

Detected boom length Zero adjustment value (boom full retraction length depending on the model)

- Operate the < > key (-) and the < > key (+) so that the detected boom length becomes the zero adjustment value. When the adjustment length is reached, press the < > key to register the adjustment value. After the adjustment value is registered, " " is shown at the left of zero adjustment value. Note: When the zero adjustment value is adjusted, the span adjustment is ne eded because the span adjusted value changes automatically. (See above chart.)

2.2.2 Boom Length Span Adjustment

- Fully extend the boom.

- Until "Boom Length" and "Span adjustment value" become highlighted on the LCD (Fig. 2.1.1), press the < > key (backward) or the < > key (forward).

Detected boom length Span adjustment value (boom full extension length depending on the model)

- Operate the < > key (-) and the < > key (+) so that the detected boom length becomes the span adjustment value. When the adjustment length is reached, press the < > key to register the adjustment value. After the adjustment value is registered, " " is shown at the left of span adjustment value.

2.2.3 Adjustment Check

- Fully retract the boom again.

- The adjustment is completed when the detected boom length is within the standard tolerance. If the value is out of the tolerance, perform the zero adjustment and span adjustment again.

2.3 Boom Angle Adjustment

2.3.1 Boom Angle Zero Adjustment

- Fully retract the boom.

- While measuring the boom angle using the sprit level type angle meter, set the boom by the boom lowering operation to the zero adjustment condition

- Until "Boom Angle" and "Zero adjustment value" become highlighted on the LCD (Fig. 2.1.1), press the < > key (backward) or the < > key (forward).

Detected boom angle Zero adjustment value

- Operate the < > key (-) and the < > key (+) so that the detected boom angle becomes the zero adjustment value. When the adjustment angle is reached, press the < > key to register the adjustment value. After the adjustment value is registered, " " is shown at the left of zero adjustment value.

2.3.2 Boom Angle Span Adjustment

- Fully retract the boom.

- While measuring the boom angle using the sprit level type angle meter, set the boom by the boom lowering operation to the span adjustment condition.

- Until "Boom Angle" and "Span adjustment value" become highlighted on the LCD (Fig. 2.1.1), press the < > key (backward) or the < > key (forward).

Detected boom angle Span adjustment value

- Operate the < > key (-) and the < > key (+) so that the detected boom angle becomes the span adjustment value. When the adjustment angle is reached, press the < > key to register the adjustment value.

After the adjustment value is registered, " " is shown at the left of span adjustment value.

2.3.3 Adjustment Check

- Set to the zero adjustment condition again, and measure the boom angle using the sprit level type angle meter

- The adjustment is completed when the difference between the detected boom angle display and angle gauge is within the standard tolerance. If the value is out of the tolerance, perform the zero adjustment and span adjustment again.

2.4 Slewing Angle Adjustment

2.4.1 Slewing Angle 1 Zero Adjustment

- By the right (clockwise) slewing operation, set the slewing angle to the over-front.

Detected slewing angle 1 Zero adjustment value

- Operate the < > key (-) and the < > key (+) so that the detected slewing angle 1 becomes the zero adjustment value. When the adjustment angle is reached, press the < > key to register the adjustment value.

After the adjustment value is registered, " " is shown at the left of zero adjustment value.

2.4.2 Slewing Angle 2 Zero Adjustment

- Keep the slewing positions same as 2.4.1.

- Until "Swing (Slewing) Angle2" and "Zero adjustment value" become highlighted on the LCD (Fig. 2.1.1), press the < > key (backward) or the < > key (forward).

Detected slewing angle 2 Zero adjustment value

- Operate the < > key (-) and the < > key (+) so that the detected slewing angle 2 becomes the zero adjustment value. When the adjustment angle is reached, press the < > key to register the adjustment value. After the adjustment value is registered, " " is shown at the left of zero adjustment value.
