This Timpte trailer is designed for operation within legal posted speed limits on reasonable road surfaces for the
type of service it was built to perform, in accordance with the noted weight restrictions.
“Normal Service” means the loading and transportation of uniformly distributed loads of properly secured, noncor-
rosive cargo, in accordance with any applicable factory instructions and in a manner which does not subject the
trailer or parts of the trailer to (a) concentrated loads; (b) loads in excess of the Gross Axle Weight Rating (GAWR)
or Gross Vehicle Weight Rating (GVWR) stated on the Certication Plate afxed to the trailer by Timpte; and (c)
accidental damage, or (d) stresses, impacts or shocks greater than those commensurate with normal, reasonable
lawful use.
The GAWR (gross axle weight rating) is the structural capability of the lowest rated member of the running gear
components: suspension system, hubs, brake drums, wheels, bearings, axles, brake linings or tires.
The GVWR (gross vehicle weight rating) is the structural capability of the trailer when supported by the kingpin and
axles with the load uniformly distributed throughout the cargo space.
NORMAL TRAILER OPERATION
The maximum load indicated on the identication plate
may not be a legal load on the highway you plan to use.
States have diering laws and regulations aecting
vehicle lengths and weights on roads that are not a part
of the primary interstate road system.
Modication of the Trailer – Any modication made to the trailer must comply with DOT and NHTSA reg-
ulations and must not compromise the gross vehicle weight rating (GVWR) of the trailer. Any modication made to
the trailer without prior approval of Timpte may void the warranty. Any operation of the trailer outside the limitations
stated in this manual will void any responsibility of Timpte, Inc. for any of its results.

AIR BRAKE SYSTEM
Your new Timpte trailer is equipped with an air brake system which meets or exceeds the requirements of the federal
regulation FMVSS-121 for grade-holding ability and emergency stopping in the event of an air supply failure in the
service brake system. Air pressure is required to release the parking/emergency brake. As of 10/8/92-FMVSS 121
requires that the supply line for the air brake system be protected to 70 psi. This pressure level requires that supply
line pressure levels are achieved before the pressure protection valve opens (opening pressure must be higher than
the closing pressure by design).
Keeping your compressor cut-in pressure at maximum levels (over 100 psi) is a clear advantage for peak operation of
your entire system, we recommend using a 105 psi cut-in governor setting. Governor cut-out pressure should be at
120 psi minimum. Low compressor cut-in pressure may result in poor performance of the system, for example slow
parking brake release time.
Should you still have a problem with your brake system after working through all of the inspection items and tests listed
in this manual’s maintenance section, contact your Timpte factory representative.
WHEEL NUT TORQUE
Proper torquing and retorquing the wheel nuts are critical to prevent the loss of wheel equipment. Wheel nuts should
be torqued to 450 to 500 ft. lbs. (dry). Refer to the manufacturer’s decal on the side of the trailer or manufacturer’s
maintenance information supplied with the trailer for proper torque specications and tightening sequence.
Wheels must be checked and retorqued after the rst 50 to 100 miles of use. This is important every time you change
a wheel. Check the fastener torque on a regular on-going basis.
REAR IMPACT GUARDS
WARNING
1. Read and understand this warning and the installation, Service and Safety Instruction Manual to understand
all safety precautions, proper operation, and maintenance of your Webb hub. Failure to do so could result in
death or serious injury and could result in a compromise of your vehicle’s safe operation through loss or failure
of a wheel or the compromise of the braking system. Copies of the installation, Service and Safety Instruction
Manual are available, free of charge, from Webb Products, Inc., upon request.
2. Always use a properly installed calibrated torque wrench to assure proper torque. Under torque and over
torque can cause thread and/or nut damage and could result in the loss of a wheel. Failure to ensure proper
torque could result in death or serious injury and could shorten the expected life of this product.
3. Recheck torque after the first 50 to 100 miles of service. Parts may seat naturally, causing the torque to drop.
A drop in torque could result in the loss of a wheel. Proper torque is essential to avoid damage or compromise
of your vehicles safety. Failure to ensure proper torque could result in death or serious injury.

ABS BRAKING SYSTEM
As of 3/1/98 all trailers manufactured with air braking systems are required to have an ABS (Anti-Lock Braking
System).
The system used on your trailer meets or exceeds the FMVSS 121 requirement for ABS. The ABS system on
your Bulk Commodity trailer is a 4S/2M system (4 wheel sensors - 2 modulator valves) or a 2S/1M (2 wheel sensors
- 1 modulator valve). The intended purpose of ABS is to help maintain control and reduce the likelihood of jackknife
situations.
The ABS status indicator light is located on the driver side of the trailer near the rear corner post. It indicates the
system status upon initial startup by turning on and then turning off once the vehicle begins to move. If a malfunction
in the ABS system occurs, the ABS system status light will come on and stay on until the problem is repaired. Anytime
the system status light comes on and stays on, have the ABS system serviced as soon as possible.
WARNING! ABS (Anti-Lock Braking System) is a safety item and must be
properly maintained. To operate an ABS equipped truck and trailer properly, during
braking- constant pedal force must be applied. All ABS systems require clean, dry
air to operate properly. Use of airline deicers or leakage of oil into the air system
may diminish the performance of the system and will void the warranty.
BACKUP WARNING SYSTEM
A backup warning system consisting of an audible alarm is available as an option on your Timpte Bulk Commodity
trailer. The system is intended to indicate that the vehicle is backing up.

Date of Origin – 02/24/11 Updated – 02/03/20
1. You, the operator, have control of the most important factors that affect safe trailer operation and vehicle
stability. Trailers are a tool and, like any tool, are safe only when properly used by a conscientious, trained
and qualied operator.
2. The fth wheel should be securely mounted to the tractor frame and proper connection
between the tractor and trailer veried.
3. The driver should be familiar with the characteristics of the particular trailer and of the load to be
transported.
4. The driver should be familiar with the nature of the roads and trafc which may be encountered during
the trip.
5. Stability – Caution - like any other vehicle, semi-trailers can tip or slide out of
control if turns are negotiated at too high a speed or when making violent
maneuvers such as abrupt lane changes or other evasive actions to avoid
obstacles.
6. Within the relatively narrow connes of road laws limiting vehicle size and weight, together with the
characteristics of available tires, suspensions, and other components, there is little that a manufacturer can
do to affect the inherent stability of a trailer other than keeping the load as low as feasible, considering the
requirements for loading space and adequate tire clearance. This means that the major factors affecting
operational stability are the knowledge and skill of the driver. The predominant causes of rollover
accidents are:
a. Excessive speed
b. Violent swerving or turning
c. Application of brakes or tractor power while turning.
d. Entering curves at too high a speed
7. Tire Characteristics: High pressure truck/trailer tires have different characteristics under high speed corner-
ing conditions than do passenger car tires. Truck/trailer tires are designed for carrying high loads over long
distances. Their lateral stability becomes unpredictable when lateral forces approach .04g. This means
that commercial vehicles must be operated in a conservative manner when cornering.
8. Braking and Acceleration: Either braking or accelerating while cornering can signicantly reduce the stability
of the vehicle and should be avoided. The best driving practice is to decelerate to a safe conservative
speed before entering a corner or approaching congested trafc, and then to apply only moderate power
until a straight path has been re-established.
You, the operator, have the Greatest Control
over Safe Operation.

TRAILER KINGPIN WEAR
Per Recommended SAE Standards, check King Pin for
wear across the pin neck and also the pin shoulder. In
accordance with industry standards, Timpte recommends
that the kingpin and its mounting structure be inspected
for wear and damage on a daily basis.
1. Measure the neck - 2”
A. Insert the head of the Kingpin through the
large opening of the small slot. Locate the
gage between the shoulder and the head of
the Kingpin.
B. Slide the gage toward the small end. The number stamped on the gage at the center
of the Kingpin indicates the dimension (see gure 1).
C. The Kingpin should be replaced when, at any orientation, the neck OD measures
1 7/8” diameter.
2. Measure the shoulder - 2-7/8”
A. Repeat the above procedure using the large slot on the shoulder of the Kingpin (see gure 2).
B. The Kingpin should be replaced when, at any orientation, the shoulder OD measures 2 ¾” diameter.
TRAILER KINGPIN TO COUPLER INTERFACE INSPECTION CRITERIA
3. Measure the Kingpin length
The Kingpin is the proper length if the “MAX” end engages and the “MIN” end does not engage as shown below.
Important: Be sure to hold the gage edge at to the upper coupler. Check both the “MAX” end and the “MIN”
end as shown in gures 3 and 4.

Reference SAE J700 standard for upper coupler to kingpin interface
WARNING
TO INSURE PROPER ENGAGEMENT OF THE
KING PIN TO THE FIFTH WHEEL COUPLER,
THE KINGPIN MUST BE MAINTAINED WITHIN
RECOMMENDED SAE STANDARDS. FAILURE TO
DO SO COULD CAUSE SERIOUS INJURY OR
DEATH.

WARNING! Be careful when making inspections, hookups and repairs to
avoid personal injury. Make sure parking brakes are properly activated or that
wheel chocks are in place to avoid sudden or unexpected movement of the
trailer which could result in bodily injury.
It is the Operator’s responsibility to conduct a safe and accurate pre-
trip inspection of the vehicle. Per Federal Motor Carrier Statute 49 CFR
392.7 Equipment, Inspection and Use - No motor vehicle shall be driven
unless the driver thereof shall have satised himself that the following
parts and accessories are in good working order, nor shall any driver fail
to use or make use of such parts and accessories when and as needed

NOTICE:
Additional Federal Requirements for the Operator can be found in the Federal Motor Carrier Safety Regulations
(FMCSR’s) in the Code of Federal Regulations (CFR) Title 49 Parts 392, 393 and 396. These can be found on-line at
http://www.access.gpo.gov/nara/ then scroll down to (CFR Sections by Citation).
Failure to regularly inspect the trailer may also void the warranty.
While it is ultimately the operator’s responsibility to properly perform and document the pre-trip inspection, Timpte
provides the following recommendations and suggestions.
Inspection Procedures Before Each Trip

13 Date of Origin – 02/24/11
Updated – 02/03/20
LIGHTS AND REFLECTORS
The surfaces of the lights and reectors need to be checked and cleaned. Inspect all lights to see if they are working
and check all brake and signal functions.
ELECTRICAL WIRING
Inspect all visible wiring to see that it is not frayed and is properly supported and protected, and that all connections
are tight. Inspect the electrical hookup for a clean and secure connection.
FIFTH WHEEL AND KING PIN ENGAGEMENT
Inspect the kingpin and its structure on the trailer for damage or unusual wear. After hook up, make a direct visual in-
spection to assure proper coupling, then check for positive engagement of the lower fth wheel and king pin. Apply the
trailer brakes and attempt to move the tractor forward to insure that the fth wheel and king pin are positively locked.
CAUTION! Plastic King Pin Liners (Lube Plate) cannot be installed onto Timpte Trailer upper cou-
pler/king pin assemblies unless the trailer was purchased with that specication. A lube plate changes
the king pin interface dimensions relative to the fth wheel lock. This may result in coupling difculties,
premature lock wear, and a potential for a dropped trailer.
TIRES
WARNING! DO NOT OVERLOAD! Check tires frequently for cuts and abrasions. Check tire
pressure daily and keep inated as recommended by the tire manufacturer. Remove foreign objects that
may be lodged in the tire treads or between dual tires.
MUD FLAPS
Be sure the mud aps are securely in place and in good condition.
TARP SYSTEM
Check to be sure the tarp is in serviceable condition. Insure that the latching system is in good working order and that
the tarp is properly secured for travel to prevent being blown about by the wind.
LANDING GEAR
Always raise the landing gear legs completely before moving the trailer. Make sure that the crank handle is properly
secured. Prior to trailer transport, lock landing legs into low side gear ratio.
HUB MAINTENANCE
Check wheel studs for good condition – no stripped threads – no bent or loose studs. Replace any broken or bent
studs or studs with damaged threads. When a broken stud is replaced, the stud on each side of it should be replaced
at the same time. If more than two studs on the same hub are broken, replace all of the studs.

14
Date of Origin – 02/24/11 Updated – 02/03/20
WHEELS AND RIMS
Check all wheel nuts for tightness. Wheel ange nuts should be torqued to 450 to 500 ft. lbs (dry).
Check all metal surfaces thoroughly while making tire inspections and during tire changes.
Look for:
• Excessive rust or corrosion build-up
• Cracks in the metal
• Bent anges or components
• Loose, missing, or damaged nuts
• Bent or stripped studs.
• Incorrectly matched rim parts
Replace damaged components, making sure that replacements are made with proper sized and type parts.
WARNING
EXCESSIVELY CORRODED OR CRACKED RIMS ARE DANGEROUS, PARTICU-
LARLY DURING REMOVAL. DEFLATE TIRES PRIOR TO REMOVAL OF RIMS AND
WHEELS FROM THE VEHICLE OR PERSONAL INJURY COULD RESULT.
HUB LUBRICANT
Check and maintain proper level of lubricant in hubs.
Hubs using oil lubricant will have clear hub windows and the oil level will be clearly visible. Be sure the oil level is at
the ll line noted on the hub window.
Hubs equipped with synthetic grease will retain the grease between the bearings and no lubricant visual check is pos-
sible. Trailers equipped with this option will not have a clear hub window or a ll plug.
Do not add oil to hubs equipped with synthetic grease lubricant. If mixing of lubricants occurs, remove the lubricant
and re-install the proper lubricant as soon as possible.

SIDE STRUCTURES
Check the trailer sides for inconspicuous damage to the top and bottom rails as well as the side structure – cracks,
contusions, sharp bends, ripples, or missing fasteners. Any problems observed in the side structure should be correct-
ed immediately to prevent the damage from extending further. Unrepaired damage could affect the safe load carrying
capacity of the side structure.
SUSPENSION AND SUSPENSION SUBFRAME
Check the suspension and suspension subframe structure for damage or unusual wear. Any type of damage, cracks
in the welds or structural members or loose fasteners need to be addressed immediately. Check air ride suspensions
for condition of bushings, air leaks, condition of shock absorbers, for proper operation of ride height leveling valve, and
for proper ination of the air springs.
NOTE: Never move an air ride trailer without rst fully inating the air springs – failure to
do so could cause damage to the trailer and suspension and will void the warranty.

PARKING/EMERGENCY BRAKING SYSTEM
This portion of the air brake system makes provision for parking a vehicle on a grade and for emergency stopping in
the event of a failure of air supply in the service brake system.
Air pressure within the parking brake chamber is required to release the spring brake. An air reservoir is provided to
store enough air to release the brakes at least once by means of the tractor parking brake control, if there is an air line
failure. In addition to the normal release of spring brakes using air, a built-in manual release is provided. It allows easy
release of the spring brakes for relining the brakes or for moving the trailer in the absence of air pressure.
WARNING
DO NOT ATTEMPT TO MOVE THE TRAILER UNTIL PARKING BRAKE IS FULLY RE-
LEASED. FAILURE TO FOLLOW THIS SAFETY WARNING WILL RESULT
IN EQUIPMENT DAMAGE AND COULD RESULT IN SERIOUS INJURY
OR DEATH.
DANGER
MANUAL RELEASE OF THE PARKING BRAKE SHOULD ONLY BE USED TO MOVE
THE TRAILER TO A SAFE LOCATION WHERE REPAIRS CAN BE PERFORMED.
ALWAYS INSTALL WHEEL CHOCKS IN FRONT OF AND BEHIND TIRES BEFORE
MANUALLY RELEASING SPRING BRAKES. FAILURE TO FOLLOW THIS SAFETY
WARNING COULD RESULT IN DEATH OR SERIOUS INJURY.
WARNING
NEVER ATTEMPT TO USE THE TRAILER FOR THE MAJORITY OF THE BRAKING
EFFORT BY BACKING OFF THE TRACTOR BRAKES. THIS IS ILLEGAL, UNSAFE,
AND WILL CAUSE PREMATURE FAILURE OF THE TRAILER BRAKE SYSTEM.
FAILURE TO FOLLOW THIS SAFETY WARNING COULD RESULT IN
DEATH OR SERIOUS INJURY.
