2- Height Adjustment; 3- Damper Adjustment; 4- Fore-Aft Position Adjustment - Hitachi ZW180 Operator's Manual

2- Height Adjustment

The seat height adjustment is an air pressure control type
by which the seat height can be adjusted steplessly. Fully
pull upward or push downward lever (2) until the desired
seat height is obtained.
IMPORTANT: Do not continuously operate the lever for
more than 1 minute. Damage to the suspen-
sion seat may result.
A position where the seat does not rise further even though
the lever is continuously pulled is the highest position.
When the seat reaches the highest position, the seat is auto-
matically moved downward by a small stroke to provide the
suspension stroke.
NOTE: Conduct the weight and height adjustment with
damper adjusting knob (3) set in the soft position.

3- Damper Adjustment

The damper stiffness can be adjusted in accordance with
the type of work engaged in or the conditions of the road
surface.

2: Soft
Be sure to adjust the seat height with the damper adjusting
knob set in soft position (2).

4- Fore-Aft Position Adjustment

Pull up slide lever (4) to adjust the front/rear position of the
seat assembly. Release the lever after the seat assembly is
moved to the desired position. Check that the seat assembly
