MACHINE OPERATIONS AND CONTROLS
METHOD FOR ADJUSTING
METHOD FOR ADJUSTING OPERATOR'S SEAT
When adjusting the position of the operator's seat, always set the lock lever to LOCK position to pre-
vent any malfunction due to accidental contact with the control levers.
• Always adjust the operator's seat before starting each operation or when the operators change shift.
• Adjust the operator's seat so that control levers and switches can be operated freely and easily with the
operator's back against the backrest.
METHOD FOR ADJUSTING SEAT IN FORE-AND-AFT DIRECTION
Pull up fore-aft adjustment lever (1), set the seat to the desired
position, then release fore-aft adjustment lever (1).
Fore-and-aft adjustment: 50 mm (5 stages)
METHOD FOR RECLINING SEAT
The seat can be reclined more when the seat is pushed to the front. The amount of reclining decreases as the
seat is pushed back, so when moving the seat back, return the backrest to the original position.
