file mechanical suspension, and an Operator
Presence Sensor (OPS).
2. The seat bottom is covered with a heavy-duty
vinyl fabric. An OPS in the form of a switch, is
integrated into the seat bottom and is con
-
nected to the machine electrical system. The
seat back is also covered with a heavy-duty
vinyl fabric, it adjusts to recline up to 16
degrees, (lever actuated on operator’s left
side). The armrests are adjustable for operator
comfort (knob inside armrests actuated from
the bottom). Roller bearing single-locking
tracks provide easy repositioning fore/aft over
8” (lever actuated on lower right).
3. A mechanical suspension mechanism incorpo-
rates weight/ride adjustment controls for oper-
ators in the 125 to 275 lb. weight range, pull
upward on the fold-out lever and “pump up” to
increase seat load capacity and firmness.
Push the lever downward to reduce the firm
-
ness and load capacity. Just center the orange-
colored indicator to achieve your exact weight
setting.
4. A retractable seat belt assembly with inertia-
lock is attached to the “ride” portion of the seat
frame. When the seat latch is released, the
complete seat assembly and seat base can be
pivoted forward - this provides access to the
battery, hydraulic reservoir and filter, as well as
some of the electrical system and control link
-
ages. The seat base must be latched prior to
machine operation.
Note: The seat base must be secured by
latching, otherwise, the seat assembly could tilt
forward. The Operator Presence Sensor must be
connected to the electrical wiring harness.

umn. It can be adjusted rearward/upward or

2. The Steering wheel has an adjustable tilt fea-
ture so that the steering wheel can be infinitely
adjusted to individual needs. An adjustable
handle is used to release or apply clamping
action that secures the tilt steering wheel in the
desired position. The handle incorporates a
“ratchet” feature to allow the handle to be posi
-
tioned as desired. See Figure 2 below.
