1. Fully retract all four outrigger beams.

2. Until "RFront O/R" and "Zero adjustment value" become highlighted on the LCD (Fig. 2.1.1), press the < > key (backward) or the < > key (forward).

Detected Right Front outrigger length Zero adjustment value

3. Operate the < > key (-) and the < > key (+) so that the detected Right Front outrigger 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.

4. Also for the outrigger length of Left Front, Right Rear, and Left Rear, operate the < > key (backward) and the < > key (forward) to show the zero adjustment display, and then perform the adjustment and registration.

1. Fully retract the jib again.

2. The adjustment is completed when the detected jib length is within the standard tolerance

If the value is out of the standard tolerance, perform the zero adjustment and span adjustment again.

2.7 Jib Offset Angle Adjustment (Offset Angle to Boom)

2.7.1 Jib Offset Angle Zero Adjustment

1. Set the jib offset angle to the zero adjustment condition. (Example of -5°: At the boom angle of 5°, set the jib to become horizontal.)

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