OPERATING INSTRUCTIONS
3-9
Tail/Axle Control Lever
The TAIL/AXLE CONTROL lever is located on the
control panel (See Figure 3-3.) The lever is used both for
loading/unloading and dock leveler operation. See step 2
of “Dock Leveler Control Operation (Option)” on
page 3-17
for use of TAIL/AXLE CONTROL LEVER for
dock leveler operation. The TAIL/AXLE CONTROL
LEVER is beside the winch control lever and has three
positions:
Air Suspension Dump Valve
1. The 900C Series semitrailer comes equipped with a
“dump valve” on the air ride suspension as standard
equipment
(See Figure 3-3.) The valve has two
primary purposes.
2. When the trailer is in the load position (tail down), you
can dump the air (turn knob to ON) to achieve the
lowest load angle.
a. It is NOT necessary to dump the valve each and
every time that you ground load; however, when
you need to minimize the load angle to load on
the tail or over the hinge, then you can dump the
air. The only time to operate the dump valve
during the ground loading process is while the
axles are in the foremost forward position.
IMPORTANT
Do not operate the axles while the air is dumped
(knob turned on).
b. To load, bring your axles forward until your travel
cylinder stops, dumped the air (turn knob to ON).
c. Before returning the trailer axles to transport
position, return the dump valve knob to the OFF
position. This will inflate the air suspension and
give proper clearance for the tires and traveling
undercarriage.
3. While loading from a dock (tail at dock height), the
dump valve will exhaust all air from the suspension.
This places the suspension and trailer in the most
stable position for loading heavy equipment from a
dock onto the trailer deck.
a. It is common to use the dump valve each and
every time while loading/unloading from a dock.
It adds stability and safety to the operation.
b. To load from a dock, bring the undercarriage
forward to engage the dock arm. Return the
undercarriage rearward and raise the tail a few
inches above dock height.
c.
Dump the air (turn knob to ON position). The air will
exhaust from the suspension and lower the tail to
dock height. If you need to adjust the axles to better
match the dock height, it is ok to move the axles
forward or rearward those few inches to accomplish
the required height.
DOWN/LOAD In this position, the undercarriage
slides forward for loading.
CENTER This is the neutral position. The
semitrailer stays in its current position.
UP/ROAD In this position, the undercarriage
slides to the rear. The undercarriage
must be in the rear-most position for
transport.
