Safety Precautions,
Hazard Seriousness Level
Youwillndsafetyinformationboxesthroughout
this manual. These boxes contain information alerting
you to situations or actions to avoid.
Signal words (DANGER, WARNING and CAU-
TION) are used to identify levels of hazard seriousness.
Their selection is based on the likely consequence of
humaninteractionwithahazard.Denitionsofhazard
levels are as follows.
DANGER - Immediate hazards which
will result in severe personal injury or death.
WARNING - Hazards or unsafe prac-
tices which could result in severe personal
injury or death.
CAUTION - Hazards or unsafe practic-
es which could result in minor personal injury
or product or property damage.
WARNING
FLUOROELASTOMER HANDLING
Some O-rings and seals used in this vehicle
are made from uoroelastomers, When used
under design conditions, uoroelastomers do
not require special handling. However, when
uoroelastomers are heated to temperatures
beyond their design temperature (around 600º
Fahrenheit), decomposition may occur with the
formation of hydrouoric acid. Hydrouoric acid
can be extremely corrosive to human tissue if
not handled properly.
A degraded seal may appear as a charred or
black sticky mass, Do not touch either the seal
or the surrounding equipment without wearing
neoprene or PVC gloves if degradation is
suspected. Wash parts and equipment with
10% lime water (calcium hydroxide solution) to
neutralize any hydrouoric acid.
If contact with the skin occurs, wash the
affected areas immediately with water. Then
rub a 2.5 calcium gluconate gel into the skin
until there is no further irritation, while seeking
prompt medical attention.

OPERATION
Operation Instructions
General Description of Operation
Etnyre Live Bottom trailers are designed to carry
and unload the maximum rated volume of payload at
a controlled rate.
Horizontal rear unloading is accomplished by a hy-
draulically powered conveyor belt.
Power to drive the hydraulic pump is supplied from
the tractor engine through the Power Take-Off (PTO)
system. Quick disconnect hydraulic hose couplers
located near the tractor cab are used to deliver pump
owtothemotorandgearreductionunitlocatedonthe
trailer. The hoses may be disconnected without loss of
oil or air entering the hydraulic circuit.
Tractor engine rpm and hydraulic pump speed is pri-
marily used to control the rate of material discharge. If
the rate of material discharger is too fast at engine idle
speed,anadjustableowcontrolvalvecanbeusedto
divertpartialpumpowtotheconveyormotorbackto
tank.Ifequipped,theowcontrolvalvewillbelocated
at the left rear corner of the trailer.
Pump Performance Recommendations
Efcientoperationofthelivebottomtrailerwillbe
dependent on the tractor mounted hydraulic pump per-
formance. The pump must meet the following minimum
performance criteria.
Pump Speed: 1200 rpm
Average Output Flow at 3000 psi: 30 gpm (114 lpm)

condition. Minor damage can quickly result in a major
failure if not repaired.
WARNING
Do not operate a trailer needing repair
Do not undersize the prime mover. The prime
mover (tractor) must be compatible with the
trailer and have adequate capacity
Do not exceed either the GVWR or GAWR shown
onthecerticationlabel,Theseratingsaremaximum
for the trailer. Exceeding these values may result in
damage and will shorten the life of the trailer.
Keep personnel clear when loading and unloading
trailers.
Trailer to Tractor Connecting Procedures
1.Inspectthefthwheelareaandthetrailerframe
for wear, structural cracks, damaged or broken steel.
Figure 4. Measuring Kingpin
2. Check the kingpin for wear or damage. Replace it
if the diameter measures less than 1 7/8” at any point
(see Figure 4).
3. Check the bolts for tightness. Tighten if required.
Refertogure3forcorrecttorquevalues.
4.Connectthetrailertothefthwheel.
5. Connect the glad hands and build up reservoir air
pressure.
6. Connect the plug into the electrical socket.
WARNING
Check to insure that the kingpin is locked into
the tractor fth wheel.

OPERATION
7.Checkthe lights,turnsignals andreectorsfor
operation.
8. Before operating the trailer, test the airbrake sys-
tem using the following procedure:
a. Check the air system pressure. The system must
hold 100 psi (7 Bar) minimum.
b. Apply the brakes. Inspect the brake action on all
the wheels for proper application.
c. Release the brakes. The brakes must release
promptly. The air pressure must discharge quickly from
the relay emergency valve.
d. Disconnect the emergency line to the trailer. The
trailer brakes must automatically apply.
e. Connect the emergency line to the trailer. The
trailer brakes must release.
9.Checkthetiresforproperinationpressure.In-
spect the tires for cuts or other damage.
10. Hook up the hydraulic lines and engage the
pump.
11. Check that the belt is turning freely.
Unloading Without Flow Control Valve
Use the following procedure to discharge material if
aowcontrolisnotused.
1. Put the transmission in neutral and disengage the
clutch.
2. With the tractor engine at idle, engage the PTO
drive.
3. Slowly engage the clutch
4. Increase the tractor engine rpm to the desired rate
of discharge.
IMPORTANT: Always idle the tractor engine
before engaging the PTO drive.
After the load is discharged, make at least two revo-
lutions of the conveyor to dislodge any excess material
left on the belting.
WARNING
Always disengage the PTO drive and shut
down the engine before entering the trailer
hopper or performing any cleaning or service of
any kind.
The use of fuels or oils on the sidewalls of the trailer
hopper when hauling hot mixes should be held to a
minimum. Normally, one coat of fuel or oil once a day
is recommended at the end of each days hauling.
NOTE: Always check with your local and state
regulatory agency regarding the use of and/or disposal
of fuel or oil as a wash down or sidewall lubricant for
hot mix. The use of biodegradable oils for this purpose
is strongly urged to protect the environment.
Trailer Loading General Information
It is generally recommended to scale the trailer to
get the correct load distribution because of various
fth wheel settings and different types of payload
material.
WARNING
Do not load the trailer beyond its rated
capacity. Overloading can affect stability and
reliability of the trailer.
IMPORTANT: Heat and oil resistant type conveyor
belting must not be used when the ambient temperature
reach 20ºF or below. Use of this type of belting below
20ºF will void the warranty.
Operating the Manual Tarp (optional)
To cover the trailer hopper:
1. Release the crank handle from its storage posi-
tion.
2. Turn the crank clockwise until the hopper is com-
pletely covered.
3. Return the crank to its storage position.

12
OPERATION
WARNING
To prevent injury, keep hands and clothing
clear of the chain and sprocket when the crank
is being operated. DO NOT operate the tarp
under obstructions such as trees or power lines
To uncover the trailer hopper:
1. Release the crank handle from its storage posi-
tion.
2. Turn the crank counterclockwise to uncover the
trailer hopper.
3. Return the crank to its storage position.
NOTE: The tarp is also available with an electric
drive.
Lift Axle Operation
If your unit is equipped with an air lift axle, it is nec-
essary to determine the proper air pressure required in
the ride spring bags in order to have the axle support its
correct share of the load. The procedure is described on
the Hendrickson decal, L402, which is on the inside of
the air lift control box door. It is also shown here, along
with a schematic of the entire system. It is important to
follow this procedure in order to have the axle support
its correct share of the load and also to avoid having the
tires on the lift axle lock up while braking.

MAINTENANCE
Maintenance Procedures
Fifth Wheel Plate and Kingpin Inspection and Lu-
brication
Inspect the kingpin throat for signs of wear. Replace
the kingpin if worn 1/8 inch (3.18 mm) undersize (see
Figure 4).
If the grease remaining on the fth wheel plate
contains sand and dirt, clean it before lubricating. The
kingpin and the fth wheel plate should be greased
thoroughly with multipurpose grease before connecting
the tractor and trailer.
Frame Inspection
An important phase of trailer maintenance is the
inspection and repair, if required, of all structural mem-
bers of the trailer frame. The frame must be one solid
unit to carry the load. This also helps prevent major
repair costs and trailer downtime.
Complete frame inspection is required for various
reasons. Trailers are subjected to considerable abuse due
toheavyloadsanddifcultroadconditionsunderwhich
they are operated.A trailer loaded to the maximum rated
capacity and pulled at the highest rated speeds for long
periods of time, could develop structural damage faster
than a trailer carrying lighter loads at lower speeds.
Rough use and poor maintenance will shorten the life
of the trailer.
Check the trailer frame daily for cracked structure,
cracked welds, and broken, damaged or lost parts. Struc-
tural cracks will usually show best when the trailer is
loaded. Failures are the result of metal fatigue caused by
exingandvibration.Theywillappearascracksinthe
steel frame members. If repairs are needed Do Not oper-
ate the unit until the repairs are made. Structural repairs
mustbedonebypersonsexperiencedinthiseld.
Weld Repairs
Minorrepairstocrossmembers,oorplates,andother
parts which are not part of a main structural member,
may be repaired without special instruction if good
welding practices are followed.
WARNING
Repairs to major structural members must be
made according to the requirements of the
part being repaired. Care must be taken to
ensure that the repairs do not contain stress
concentrations which could lead to another
failure. Repair of T-1 steel especially requires
additional care.
Table 3 lists the recommended electrodes for the
various steels used in Etnyre trailers.
Wheel Bearings
The oil level must be maintained between the “add”
and “full” lines on the hub cap windows (see Figure
7). Check for cracked windows, missing vent plugs
and for oil leaks around the hub cap. Oil can be added
througheithertheventplugorthellerplug.Cleanand
inspect the bearings and change the oil at 50,000 miles
or at brake relinings.
Undercarriage
The undercarriage must be visually examined for
broken and missing parts. Check brackets, adjusting
screws and walking beam ends. Replace faulty parts.
Check the rim clamps or cap nuts for tightness daily.
See Figure 8fortorquespecicationsandtightening
sequence. Brake drums should be carefully examined
for cracks.

CAUTION
Do not allow brake drums to become
excessively worn or expensive repairs will be
required.
Figure 8. Lug Tightening Sequence
Suspension Alignment & Fastener Torque
The major source of costly repair bills on
suspensions is insufficient torque. After an initial
shakedown run of 1,000 miles and every 25,000 miles
thereafter, nuts on the suspension should be restored to
originaltorquespecications.

Alignment Adjustment
To assure proper alignment of the suspension,
the following steps should be followed exactly:
1.Locate thetrailer ona at,smooth surfaceand
disconnect trailer brakes.
2. With the brakes disconnected, roll the trailer
forward and rearward a distance of approximately 10
feet to relieve any binding which might be caused by
turning or braking.
3. Remove the tractor from the trailer and level the
trailer body until it is parallel to the ground, using the
landing gear adjustment. Trailer should be leveled by
measuring from the frame to the ground at the front
and rear hanger.
4. Check to make sure that there is no interference
between the springs and the hanger brackets.
5. Tighten all torque arm bolt nuts and Ubolt nuts to
thetorquespeciedabove.
6. Remove hub caps from all four trailer wheels and
install axle extensions on each end of each axle.
7. Install a Bazooka-type kingpin extension and
center the sight level.
8. Measure from the kingpin extension to either end
of the front axle and make necessary adjustments.
9. With the front axle properly aligned, measure
between the axle extensions on either end of each axle
and make necessary adjustments.
10. Remove the axle extension, kingpin extension
and install hub caps.
11. Check the nuts on the adjustable torque arm tube
clamps to insure they are tightened to torque shown
above.
Figure 9. Checking Alignment
Note A. Steps one and two are very important in the
proper alignment of your suspension and should be done
before any attempt is made to align the suspension.
Note B. The slot in the adjustable torque arm should
be located in the down position and in alignment with
the open part of the clamp to insure proper clamping.
