Operating Instructions
General
This section supplies information for operation of the
semitrailer. It describes and locates controls and gives
general operation procedures. Read all instructions,
warnings, cautions, and danger notes before attempting
to operate the semitrailer. Operators must have proper
training before operating the semitrailer.
(See Figure 3-1 and 3-2)for location of semitrailer parts.
WARNING
WARNING
Landing Gear
The landing gear consists of two legs with a tube
telescoping within another tube. Crank style is standard.
Pin drop or hydraulically operated are optional.
Parking Brake
The parking brakes are automatically applied by spring
pressure with the air actuators of the braking system
when air pressure in the emergency line drops below 50
psi. This may be done within the truck using the trailer
parking/emergency valve or by disconnecting the
emergency gladhands.
Air Brake System
The air brake system of the semitrailer is operated from
the towing vehicle after coupling. The towing vehicle’s air
system must be coupled to the semitrailer and charged to
90 psi minimum before the brakes can adequately
function.
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System of the semitrailer is constant
powered by the auxiliary (blue) circuit of the seven-way
electrical connector, with backup power from the stop
lamp (red) circuit, and ground through the white wire. It is
necessary that the blue circuit is hot when the tractor key
switch is on. The blue circuit on the trailer may not be
used to power any additional auxiliary devices while the
semitrailer is moving forward. If a fault exists in the ABS,
normal braking will occur, but the wheels may lock.
Service the ABS as soon as possible.
CAUTION
CAUTION
Do not operate the semitrailer with any known
fault that might endanger the occupants, nearby
workers, other traffic, the load, or the equipment.
Do not operate the semitrailer until you have read
the operator’s manual and completely understand
the proper use and function of all controls.
Improper use can cause personal injury, damage
to your semitrailer and cargo, and cause
time-consuming breakdowns.
The auxiliary (blue) circuit is for powering the
semitrailer ABS. This circuit must be hot when
the tractor key switch is on. No other electrical
devices may be powered by this circuit while the
semitrailer is moving forward.
If a fault exists in the semitrailer ABS, normal
braking will occur, but wheels may lock and the
ABS must be serviced as soon as possible.

TABLE OF CONTENTS
Electrical
The only electrical operation required of the operator is
interconnection of the towing vehicle electrical cable plug
with the semitrailer electrical receptacle.
It is necessary that the tractor blue wire be connected to
the appropriate electrical source on the tractor.
Hydraulic
Most controls are located on the driver’s side of the
trailer. A hydraulic pump must be coupled to the trailer
hydraulic system, or the optional hydraulic engine
package started, before any hydraulic controls can
function. The hydraulic system is designed to operate at
2500 psi maximum pressure and approximately 20 GPM
flow capacity. The control valve has a built-in flow control
that can handle 50 GPM max and it limits the function to
20 GPM. Tractor must be equipped with a relief valve
set at 2500 psi maximum pressure.
Pre-Coupling of Semitrailer and
Tractor
1. Slowly back the tractor/truck (towing vehicle) up to
the front end of the semitrailer so the kingpin of the
semitrailer is centered between the tractor fifth wheel
jaws. Stop the towing vehicle just inches ahead of the
semitrailer. Set tractor parking brake.
2. Check the semitrailer king pin plate. It should be in a
horizontal position. The king pin plate should be the
same height, to slightly lower, than the latch area of
the fifth wheel plate of the towing vehicle. Crank two
speed landing gear up or down to correct height. If
you have the optional pin drop or hydraulic landing
gear, connect the tractor hydraulic lines, or start the
semitrailer hydraulic power engine. Use the trailer tilt
knob (See Table 3-2)or hydraulic landing gear
(See Table 3-1)to raise or lower the kingpin plate
sufficiently to set proper coupling height. Drain all air
and moisture from the towing vehicle air brake
system following towing vehicle manufacturer’s
instructions.
3. Connect the service and emergency air hoses of the
towing vehicle to their respective gladhand on the
front of the semitrailer; red emergency line to the
gladhand with the “EMERGENCY” tag, and the blue
service line to the gladhand with the “SERVICE” tag
(See Figure 3-3.) Chock the semitrailer wheels
before activating the semitrailer air supply valve in
the towing vehicle. Set the parking brakes.
WARNING
4. Check the air brake operations of the semitrailer as
follows:
a. Apply brakes and inspect brake action on all
wheels for prompt application.
b. Release brakes. All brakes should release
immediately. Air pressure should discharge
quickly from the relay emergency valve.
c. Disconnect the emergency air line from the
semitrailer gladhand. Trailer brakes should
promptly set.
d. Re-connect the emergency air line to the
semitrailer and activate the semitrailer air supply
valve. The semitrailer brakes should set.
Figure 3-3: Service Hookups
Failure to chock semitrailer wheels could allow
movement of the semitrailer resulting in serious
personal injury, death, or damage to property in
its path.

Coupling of the Tractor to the
Semitrailer
DANGER
1. Verify the semitrailer wheels are chocked and brakes
function properly.
2. Make certain the coupler of the towing vehicle’s fifth
wheel is open by pulling the latch handle.
3. Slowly back the towing vehicle so its fifth wheel
contacts the front of the king pin plate on the
semitrailer and slips under it. Continue backing until
the fifth wheel coupler locks onto the semitrailer
kingpin.
CAUTION
4. Verify the vehicle coupling is secure by attempting to
pull the tractor forward a few inches. If the tractor
disconnects from the semitrailer, locate source of
coupling failure; repair before continuing; and repeat
steps 3 and 4.
5. Check that the towing vehicle couples securely to the
semitrailer before setting towing vehicle and
semitrailer parking brakes.
IMPORTANT
Keep brakes engaged for remainder of hookup,
checkout procedures and parking.
Connecting Tractor Services to
the Semitrailer
1. Connect the towing vehicle 7-pole electrical plug to
the electrical receptacle on the front of the semitrailer
(See Figure 3-3.)
IMPORTANT
The key on the plug and the keyway in the socket
must be properly aligned before inserting the plug
into the semitrailer socket.
CAUTION
2. If you have not already done so, connect the tractor
hydraulic lines to the semitrailer unless your
semitrailer is equipped with the self-contained
hydraulic power engine package.
IMPORTANT
Some oil may need to be removed from the tractor
reservoir to allow room for 12 gallons of additional oil
displaced from the trailer hydraulic system.
Keep all personnel clear of front, rear, and sides
of towing vehicle and semitrailer during coupling,
component operations, and uncoupling. Failure
to stay clear can result in serious personal injury
or death.
Pushing the semitrailer backwards can damage
parking stands.
Hydraulic operating pressures greater than 2500
psi can cause damage to the trailer.

(See Table 3-2.) Raise landing gear and secure
each leg with a park stand retaining pin in the full
“up” position before transporting.
b. For crank landing gear, retract landing gear by
turning hand crank on control panel
counterclockwise. Use low gear until the load is
off the landing gear. Then shift to high gear and
continue cranking until fully retracted. Leave the
landing gear in high gear.
2. The Landing Gear knob is located in the hydraulic
control panel (See Figure 3-4.) It has three positions:
Table 3-1: Landing Gear Knob
CAUTION
3. Activate the Trailer Tilt knob “DOWN” until the
semitrailer is fully lowered. PULL semitrailer tilt knob
OUT to the down position (See Table 3-2)until
hydraulic system works against the bottomed out
Hydraulic Tilt Cylinders.
4. Determine that the traveling undercarriage is
completely slid back to transport position. PULL the
Axle Control knob in the back position (See
Table 3-3)until hydraulic system works against the
fully extended hydraulic telescopic axle cylinder. Shut
off hydraulic power.
5. Check the operation of all lights and signals on the
semitrailer for proper response to switch positions
(stop, right turn, left turn, and clearance). Check
operation of remote function if present.
6. Check tire inflation; adjust as needed to the pressure
listed on the semitrailer VIN plate, located on the
front of the semitrailer.
7. Check tractor/semitrailer rig for air leaks. If air
leakage is found, repair the defect before
transporting.
8. Check the oil in each hub for proper level and
freedom from contamination. If hubs are
contaminated with water, dirt or some other foreign
material, clean before transporting.
9. Check tractor air pressure. Pressure must not fall
below 90 psi, even after activating brakes a couple of
times. Set parking brake and carefully remove all
wheel chocks. Set emergency brake and try pulling
forward. The semitrailer wheels must not rotate. If
semitrailer brakes do not apply,
IMPORTANT
Do not transport until defect or defects are repaired.
Failure to properly set and check parking brake,
and chock wheels when parking and during
storage, could allow movement of the
truck/semitrailer rig resulting in serious personal
injury, death, or damage to property in its path.
Always grip crank handle securely with both
hands. Never shift landing gear under load, leave
the gears in neutral or leave the crank unsecured.
LANDING GEAR Knob

Towing the Semitrailer
CAUTION
Figure 3-5: Axle Movement Warning
Driving the towing vehicle with the semitrailer coupled
requires constant attention to the overall length of the
combination. The “hinged-in-the-middle” configuration of
the tractor and semitrailer, load, and weight affect
performance. Turning, passing, acceleration, braking,
stopping, and reverse movements require special
considerations. When executing steep grades or turning
tight curves, the semitrailer must not be allowed to push
the towing vehicle, or jack knifing the semitrailer with the
towing vehicle may result. Application of the semitrailer
brakes to keep the semitrailer in tow will help prevent this
pushing. Braking should begin before descending a hill or
attempting a curve, to ensure control.
1. Make a moving test of the semitrailer brakes at low
and medium speeds before traveling at highway
speed.
The Anti-Lock Brake System (ABS) warning lamp
mounted at left rear side of the semitrailer should come
on when power is supplied to the ABS by turning the
tractor keyswitch on. The warning lamp should go off
once the semitrailer exceeds 4 mph. If the warning lamp
does not go off, a fault exists in the semitrailer ABS. Once
the vehicle speed exceeds 4 mph, the light should remain
off unless a fault occurs or the keyswitch is turned off,
then on again.
CAUTION
CAUTION
2. Monitor the air pressure gauge on the dash of the
towing vehicle. Pressure should not fall below 90 psi
at any time.
3. The semitrailer wheels track to the inside of the
towing vehicle during turns. Thus, turning corners
requires a wide swing to prevent “curb hopping”, and
to allow the semitrailer wheels to clear any obstacle
on the inside of the corner.
4. To stop, use a gradual and smooth application of
brakes. If grabbing occurs, apply less pressure -
grabbing brakes are not efficient.
DANGER
5. Backing should be done with care. Tail overhang,
semitrailer length, and allowable space must be
taken into consideration when backing the
semitrailer.
Parking the Trailer
1. Position truck/semitrailer rig on a level, solid surface.
2. Set the PARKING BRAKE,not the semitrailer
hand brake, and check for proper brake holding.
3. Chock wheels of semitrailer.
4. Check for any air leaks in lines, relay valve, brake
pods, or any other air system component.
When operating semitrailer, do not back over
curb. This will cause severe damage to
undercarriage and undercarriage cylinder.
Do not operate the trailer over 5 MPH with the
suspension deflated. This can cause irreparable
damages to the undercarriage and suspension.
If a fault exists in the semitrailer ABS, normal
braking will occur, but wheels may lock. Service
the ABS as soon as possible.
Always check behind and under the truck and
semitrailer for persons or objects before moving.
Failure to check can lead to serious personal
injury or death to others, or damage to property.

WARNING Uncoupling Towing Vehicle from
Semitrailer
1. Park the semitrailer according to instructions in
“Parking the Trailer” on page 3-7.
2. Lower the landing gear:
WARNING
CAUTION
a. Lower the optional pin drop landing gear to the
ground. Hydraulically raise front end of
semitrailer until next hole in landing gear is
available. Pin through both inner and outer legs
of landing gear. Hydraulically lower semitrailer
onto legs.
b. For crank landing gear, turn crank handle
clockwise to extend. Using high gear, lower the
landing gear until the pads make contact with the
ground. To reduce the load on the fifth wheel,
shift to low gear and crank an additional four to
eight turns. Leave the landing gear engaged in
low gear.
c. For hydraulic landing gear, extend landing gear
with knob on Control Panel until the same weight
of the trailer is on the landing gear. Extend legs
until the hole in inner leg lines up with hole in
outer leg. Secure each leg by inserting a pin.
3. Disconnect the emergency and service air lines and
attach them to the tractor gladhand holders. If
present, install dummy gladhands on trailer
couplings.
4. Disconnect the 7-pole cable and hydraulic lines from
the semitrailer and store with the tractor.
5. Pull the tractor fifth wheel plate latch release knob.
6. Attempt to pull the tractor forward. If the tractor
uncouples, verify all service lines are disconnected
and semitrailer wheels are chocked. If tractor does
not disconnect, repeat steps 5 and 6.
7. Pull the tractor away from the semitrailer.
When leaving the semitrailer unattended,
position all hydraulic controls to the neutral or
“off” position and shut off the hydraulic engine
power supply, or disconnect the tractor hydraulic
hook-up.
With pin drop or hydraulic landing gear be sure to
secure each leg with pin before leaving
semitrailer unattended.
Always grip crank handle securely with both
hands. Never shift landing gear under load. Never
leave the gears in neutral or the crank unsecured.
