3-14 HAND VALVE (OPTION)
The HAND VALVE (See Figure 3-5) is located
on the front side of rear tail channel beside the
AIR HEIGHT CONTROL VALVE . It has two posi-
tions:
RIGHT Placing the valve in this position will
exhaust the air from the air ride sys-
tem, lowering the trailer deck when
the
AIR HEIGHT CONTROL VALVE
is in the "ON" position.
LEFT Placing the valve in this position will
increase the air pressure in the air
ride system, raising the trailer deck
when the
AIR HEIGHT CONTROL
VALVE is in the "ON" position.
IMPORTANT
WHEN VEHICLE IS IN MOTION, SWITCH MUST
BE IN "OFF" POSITION FOR NORMAL HEIGHT
CONTROL VALVE AUTOMATIC OPERATION.
3-15 PRESSURE GAUGE
The PRESSURE GAUGE (See Figure 3-5) is
located near the HAND VALVE. This gauge pro-
vides air pressure information for adjusting the air
ride system manually.
3-15.1 Minimum air pressure should be at least
three (3) psi. Loosen the minimum adjust-
ment nut
(See Figure 3-5) , set the air pres-
sure at three (3) psi and tighten the nut
again.
3-15.2 Maximum air pressure should be no
more than 85 psi. Loosen the maximum ad-
justing nut
(See Figure 3-5) , set the air pres-
sure at 85 psi and tighten the nut again.
IMPORTANT
THE TRAILER LIFT LEVER (SEE SECTION 3-11)
AND THE HAND VALVE (SEE SECTION 3-14)
MAY BE UTILIZED TO RAISE OR LOWER
THEIR
RESPECTIVE END OF THE
SEMITRAILER TO CLEAR OBSTACLES DURING
TRANSPORT
(I.E. LOW BRIDGES, CURBS,
ETC.) BY FOLLOWING THE DIRECTIONS FOR
USE OF CONTROLS.
