GENERAL INFO & ID
Please note this warning and remember -
Always start and operate the engine in
a well ventilated area;
If in an enclosed area, vent the exhaust to
the outside;
Do not modify or tamper with the exhaust
system.
CALIFORNIA
Proposition 65 WARNING
Diesel engine exhaust and some of its
constituents are known to the State of
California to cause cancer, birth defects, and
other reproductive harm.
WARNING
Do not use this machine for any operation
which is not described in this manual.
If you have any questions about operation of
this machine, contact the Etnyre Service Dept
at: 1-800-995-2116 or 1-815-732-2116.
Operations that are not approved could cause
serious injury or death.
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.
Note to Physicians: For advice or treatment of
HF burns, call the DuPont Medical Emergency
number, 1-800-441-3637

manuals when operating or performing
maintenance
Reporting Safety Defects
If you believe that your vehicle has a defect which
could cause a crash or could cause injury or death you
should immediately inform the National Highway
TrafcSafetyAdministration(NHTSA)inadditionto
notifying E. D. Etnyre & Co.
If NHTSA receives similar complaints, it may open
aninvestigation,andifitndsthatasafetydefectexists
in a group of vehicles, it may order a recall and remedy
campaign. However, NHTSA cannot become involved
in individual problems between you, your dealer, and
E. D. Etnyre & Co.
To contact NHTSA, you may call the Auto Safety
Hotline toll-free at 1-800-424-9393 (or 366-0123 in the

This manual covers standard features and options.
If your unit incorporates custom features, some of the
information contained in this manual may not apply. If
you have any questions regarding this manual or your
unit, contact your dealer or the E. D. Etnyre Service
Department at 1-800-995-2116
This manual contains operation, maintenance and
service instructions for the Etnyre V series Live Bot-
tomTrailers(seegure1).Theoperatinginstructions
must be read and understood before operating the unit.
Introduction
The operator must be responsible for maintaining the
unit in good working condition.
To identify the maximum load capacity, serial number
andtypeofyourtrailer,examinetheCertication
Label on the left side of the trailer.
Figure 1. Certication Label
TheCerticationplateshowstheserialnumberof
the trailer, the vehicle and axle gross weights, the VIN
number and a condensed description of the unit
A typical model number, such as 241, would de-
scribe the following trailer:
2 41
(A) (B)
where “A” is the # of axles and “B” is the nominal
length of the trailer.
Unit Nameplate or Certication Label
The unit serial number plate or certication label
is located on the left hand side of the trailer forward
ofthelandinggearleg.Thenameplateorcertication
labelmustremainpermanentlyafxedtotheunit.(See

GENERAL INFO & ID
Serial Number Data
Theunitserialnumberonthecerticationlabelis
also stamped on a metal plate located on the left side
of frame near the kingpin and on the outside frame
member at the left hand forward corner of the frame.
(See Figure 1).
NOTE: The complete serial number must be iden-
tiedwhen ordering parts or communicatingservice
information to Etnyre.
Trailer Capacity Data
Trailers manufactured in the United States list the
maximum “Gross Vehicle Weight Rating” (GVWR) and
the maximum “Gross Axle Weight Rating” (GAWR) on
thecerticationlabel.
The Gross Vehicle Weight Rating is the sum of the
trailer weight and the trailer capacity. This is the maxi-
mum structural capacity of the trailer.
The Gross Axle Weight Rating is the maximum load
any axle can carry.
The GVWR may be reached, under certain circum-
stances, before the GAWR or vice versa.
WARNING
Do not exceed the GVWR or GAWR. These
weight limitations are independent of road
weight limitations imposed by law.
Tire and Rim Data
Thecerticationlabelliststhecorrectrimsize,tire
sizeandtireinationpressuresforthetrailer.
WARNING
Do not use undersize rims or tires. Do not
underinate or overinate the tires.
WARNING
The operator must understand the operating
instructions completely before operating the
unit. Personal injury and/or damage to the unit
may occur if the operating instructions are not
followed.
Warning and caution information is given through-
out this manual. Particular care must be given to warn-
ing and caution information contained in Section 3
(Operating Instructions) and where noted with proper
service procedures in other sections.
Note: Warningandcautiondecalsareafxedtoall
units at the factory. These decals contain warning and
caution information which must be followed by all per-
sons operating or servicing an Etnyre trailer. Any warn-
ingorcautiondecalwhichislost,ordifculttoread,
must be replaced at once. Replacement decals may be
obtained from any Etnyre dealer, or the factory.
Refer to Figure 2 for the location of the nameplate
and decals on the Etnyre Live Bottom Trailer.
Care and Maintenance
Care and maintenance information for your Etnyre
Live Bottom trailer is given starting on page 15. Main-
tenance schedules and recommended procedures must
be followed to maximize service life.
WARNING
Unsafe operation of equipment may cause
injury. Read, understand and follow the
manuals when operating or performing
maintenance.

DANGER
Read and Understand the installation, service and safety instructions manual before
installing or servicing the hub. Failure to do so may result in personal injury or death, and
may result in a compromise of your vehicle’s safety through loss or failure of a wheel or
compromise the braking system.
Use a torque wrench to assure proper torque, failure to do so will compromise your products
service, life and safety. Under torque and over torque can cause thread and/or nut damage,
and may result in the loss of a wheel.
Recheck torque after the rst 50 to 100 miles of service. Parts may seat naturally, causing
the torque to drop. Proper torque is essential for the service, life and safety of this product.
