ATTACHMENTS, OPTIONS

SEAT ADJUSTMENT

When adjusting the operator's seat, stop the machine in a safe place before starting the operation.
Adjust the seat before starting operations for the day or when changing operators.
When adjusting the seat, put your back against the backrest and adjust to a position where the brake pedal can be fully
depressed.
An air compressor built into the seat is used for adjustment (C) and (D), so turn the engine starting switch to the ON
position before starting the adjustment.
NOTICE
There is danger of damage to the air compressor, so do not keep lever (3) operated continuously for more than 1 minute.
(A) Fore-and-aft adjustment
Move lever (1) up and move the seat to the desired position and
release the lever.
Fore-and-aft adjustment: 210 mm (10 mm x 21 stages)
(B) Adjusting seat angle
Move lever (2) up, move the seat cushion at the front up or down
to set to the desired position, then release the lever.
Amount of adjustment
Forward tilt: 3 degrees
Rear tilt: 11 degrees
(C) Adjusting seat height
The seat height adjustment uses an air system, and it can be
adjusted steplessly.
When adjusting the height, pull lever (3) up fully or push it down
fully (when pulling it up, pull it until a click is felt). When the seat is
set at the desired height, release the lever. If the lever is kept
pulled up, the position where the seat does not rise any further is
the maximum height. When the seat reaches the maximum height,
the suspension automatically goes down slightly to secure the
amount of movement of the lever.
If the operator raises his body from the seat or changes the amount of weight applied to the seat during adjustment,
the air in the suspension may be discharged.
Amount of adjustment: 80 mm (3.2 in)
REMARK
If the lever is operated in the RAISE direction from the maximum height, the compressor may continue to operate
for approx. 8 seconds, but this does not indicate any abnormality with the seat.
If this happens, the compressor will stop automatically after approx. 8 seconds. The compressor will also stop if
the height control lever is operated in the LOWER direction.
