Height Adjustment:

Pull or push the handle to

adjust the seat height.

Adjust the seat so the driver’s feet can move
each pedal through its full range of motion
without fully stretching out the driver’s legs or
using force.

Damper Adjustment:

Move the lever down to

increase damping on rough roads, or up to
decrease damping on flat roads.

The damper protects the driver’s spine by
absorbing vertical vibrations and shocks. It
should be adjusted down far enough that the
driver’s feet never lose contact with the pedals.
In general, heavier drivers won’t have to adjust
the lever up.

Fore/Aft Isolator:

Rotate the isolator lever to the

left to lock the isolator, or to the right to allow
horizontal movement.

Damping horizontal shocks can be helpful with
driving off-road or pulling a tank trailer.

Seat Extension:

Pull the lever to move the seat

cushion forwards or back. The cushion moves up
to 2-3/8 inches (60 mm) in 3/8-inch (10-mm)
increments. Releasing the lever locks the
cushion in place.

Adjust the length of the seat cushion until there
is space for three fingers between the cushion’s
front edge and the back the driver’s knee. This
helps to help improve circulation in the lower
legs.

Fore/Aft Slide:

Pull the lever to unlock the seat

and slide it forward or back. Release the lever to
lock the seat in position.

Adjust the seat so that reaching and pressing the
pedals requires no effort and all dashboard
controls are within easy reach.

Seat Tilt:

Pull the lever and add or reduce

weight on the front area of the seat cushion to
move it into one of three positions. Release the
lever to lock the seat into position.

The tilt of the seat, along with the tilt of the
backrest and the contour of the seat cushion,
affects the amount of pressure placed on the
underside of the thighs and the back.

Armrest Tilt:

To adjust the armrest angle, tilt the

armrest to the highest position, then down to the
lowest position, then to the desired position.

The armrest should be at an angle where the
elbows lay lightly on it; this helps to relax the
muscles in the shoulder and neck.

ISRI Premium High Back Seat

NOTE: The seat should only be adjusted when the
vehicle is parked with the park brake on.

The seat is designed to hold a maximum weight of
330 lb.

The ISRI Premium seat has nine different features;
the controls are shown in

Fig. 7.7

Backrest Tilt:

Pull the handle out completely

and lean back or forwards to adjust the backrest
tilt. Release the handle when the correct position
is achieved. The backrest has a 52 degree range
of movement.

When adjusted, the backrest inclination should
allow the driver to reach the steering wheel with
angled arms.

Back Support:

There are two switches that

control the back areas of the seat. Making
changes to a driver’s sitting position from time to
time helps prevent driver fatigue and improves
posture.

2.1

Lumbar (Lower) Back Support:

Press the

forward button to inflate the cushion
highlighted in

Fig. 7.4

to increase support

at the lower back. This moves the driver’s
spine into a double S shape and
decreases pressure on the spine.
