METHOD FOR ADJUSTING WEIGHT AND HEIGHT OF SEAT

When adjusting the cushion and height of the seat, turn the starting switch to ON position since the air compres-
sor built in the seat is used for the adjustment.

NOTICE
Avoid using lever (1) continuously for 1 minute or longer since such practice can damage the air com-
pressor.

The seat height is adjusted pneumatically and in stepless.
1.

Pull up lever (1) fully or push it down fully to adjust the seat
height.
For adjusting the seat height, pull up lever (1) to make the
seat higher and push it down to make the seat lower.
Adjust it so that the weight adjustment indicator (2) enters
the green range.
You can adjust the height by operating lever (1) in the
green range.
Vertical adjustment range: 75 mm {3 in}
Weight adjustment range: 60 to 150 kg {132 to 330 lb}
The suspension should be adjusted in proportion to the operator's weight to protect the operator. Operate
the lever in the normal operating posture to ensure the correct weight-based adjustment at this time.

2.

After adjusting to the desired position, release lever (1).
