Operator’s Seat Adjustments
Note: The operator’s seat left console must be raised
in order to exit the cab. In the lowered or work posi-
tion, all operational functions are activated, and oper-
ator exit is blocked by the Warning Arm/Lever. In the
raised position, the all hydraulic functions of the
machine are locked out.
Note: Not all serial number machines are equipped
with all seat adjustment options

1. Seat Suspension Adjustment
Rotate the knob (1) to adjust the seat suspension
for the operator’s weight. An indicator on the front
of the seat base shows the weight adjustment in
kilograms. (1 kg = 2.2 lbs.) Adjust the seat suspen-
sion correctly to ensure a comfortable ride. See
Figure 3-22.
2. Horizontal Seat Adjustment
The seat adjustment lever (2) allows the operator to
move only the seat forward and rearward.
3. Horizontal Seat & Control Adjustment
The seat adjustment lever (3) allows the operator to
move both the seat and the controls forward and
rearward.
4. Backrest Adjustment
The backrest adjustment lever (5) allows the opera-
tor to move the backrest forward and rearward.
5. Headrest Adjustment
The headrest adjustment (6) allows the operator to
move the headrest up and down.
6. Seat Height Adjustment
The seat height adjustment allows the operator to
move the seat height up and down. To raise the seat
height, grasp the seat and lift up until you hear an
audible click. To lower the seat, raise the seat to the
highest position and then lower the seat to its low-
est position.
7. Horizontal Suspension
When horizontal suspension is turned on, shocks
from travel motion are absorbed by the seat sus-
pension.
Arm rests
Serial Numbers AJ02993 and Up: To adjust, hold arm-
rest (2, Figure 3-23) and pull out latch (3). Move the
armrest to the desired position and release latch (3).
Make sure latch (3) locks securely into a detent in the
armrest.
Serial Numbers AH02282 and before: To adjust, turn
the adjustment wheel (4).
Note: The rear of the left armrest has a turnbuckle that
may need to be adjusted to allow the left armrest to
rotate out of the way when the left console is raised.
Use the turnbuckle to adjust the armrest so it does not
contact the left control lever when raising the left con-
sole to the lock-out position.
