AIR BRAKE SYSTEM
Your new Timpte trailer is equipped with an air brake system which meets or exceeds the require-
ments 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 or in the brake manufacturer’s manual
supplied with the trailer, 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 specifications and tightening sequence.
Wheels must be checked and retorqued after the first 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.
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 yourWebb 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.

REAR IMPACT GUARDS
Asof1/26/98,alltrailersmustcomply with FMVSS 223 and 224, which specify equipment and
performancestandardsfor rear impact guards on new semi-trailers. If requiredbythisstatute,a
RIG(rearimpactguard)hasbeeninstalledonyourtrailer that has been designed to resist speci-
fiedforces and absorb energy at a specificrate in the event of a rear collision with the trailer per
thestandard. Trailer RIG’sare subject to impactsand stressindockingandloadingoperations.
Itistherefore importantthatyouinspectthemregularly for signs of damage or wear. Failure to
follow this warning could result in serious injury or death.

7Date of Origin – 02/01/08
Pre-trip inspections should be made of the guard to assure its integrity and strength. Broken
welds, bent components, or other damage will likely affect its performance.
For these reasons, RIG inspection, service and repair records should be maintained. Repairs
and replacements must be in accordance with the original design specifications of the guard. Any
questions regarding repair or replacement should be directed to the Vice President of Engineer-
ing at Timpte.
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 forABS. 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 ofABS is to help
maintain control and reduce the likelihood of jackknife situations.
TheABS 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 theABS system occurs, theABS 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.
WARNING
!
A DAMAGED REAR IMPACT GUARD MAY NOT BE AS STRONG AS THE ORIGI-
NALLY MANUFACTURED GUARD AND MAY NOT SATISFYTHE PERFORMANCE
STANDARDS OF FMVSS 223 AND 224. ALTERATIONS OR REPAIRS TO THE RIG
COULD HAVE THE SAME EFFECT. PRIOR TO REPAIRING OR MODIFYING ANY
TIMPTE RIG, CONTACT THE VICE PRESIDENT OF ENGINEERING AT TIMPTE AT
402-367-3056. FAILURE TO FOLLOW THIS WARNING COULD RESULT
IN SERIOUS INJURY OR DEATH.

1. You, the operator, have control of the most important factors that affect safe trailer opera-
tion and vehicle stability. Trailers are a tool and, like any tool, are safe only when properly
used by a conscientious, trained and qualified operator.
2. The fifth wheel should be securely mounted to the tractor frame and proper connection
between the tractor and trailer verified.
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 traffic which may be en-
countered 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 ma-
neuvers such as abrupt lane changes or other evasive actions to avoid ob-
stacles.
6. Within the relatively narrow confines of road laws limiting vehicle size and weight, to-
gether 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 cornering 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 significantly
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 con-
gested traffic, 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.

9Date of Origin – 02/01/08
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 un-
less the driver thereof shall have satisfied 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
Service Brake, including trailer brake connections
Parking Brake
Steering Mechanism
Lighting devices and reflectors
Tires/Tire Pressure
Horn
Windshield Wiper or wipers
Rear-vision mirror or mirrors
Coupling devices
Hoses andAirlines
Fifth Wheel Plate
Gladhand Connections
Hub Maintenance
Mud Flaps
RIG (Rear Underride Guard)
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.
TRAP DOOR LOCKS
Check all trap door locks before each trip to insure that they are in proper working order. Any trap
door components which show excessive wear should be replaced immediately. Care should be
taken to keep the area around the door frame clear of any debris. Abuild-up of refuse may result
in the doors not completely closing.
Make sure all doors are closed and secured prior to departure.
Inspection Procedures Before Each Trip
!

10
Date of Origin – 02/01/08
LIGHTS AND REFLECTORS
The surfaces of the lights and reflectors 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 inspection to assure proper coupling, then check for positive engagement of
the lower fifth wheel and king pin. Apply the trailer brakes and attempt to move the tractor forward
to insure that the fifth wheel and king pin are positively locked.
CAUTION! Plastic King Pin Liners (Lube Plate) cannot be installed onto Timpte Trailer
upper coupler/king pin assemblies unless the trailer was purchased with that specifi-
cation. Alube plate changes the king pin interface dimensions relative to the fifth
wheel lock. This may result in coupling difficulties, premature lock wear, and a poten-
tial for a dropped trailer.
TIRES
WARNING! DO NOT OVERLOAD! Check tires frequently for cuts and abrasions.
Check tire pressure daily and keep inflated 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 flaps 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.

11 Date of Origin – 02/01/08
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. NOTE: Hub cap mounting bolts (6) torque 10 to 15 ft. -lbs
torque per bolt.
WHEELS AND RIMS
Check all wheel nuts for tightness. Wheel flange 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 flanges 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 RIMSARE 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 fill line noted on the hub window.
Hubs equipped with synthetic grease will retain the grease between the bearings and no lubricant
visual check is possible. Trailers equipped with this option will not have a clear hub window or a
fillplug.
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 ob-
served in the side structure should be corrected immediately to prevent the damage from extend-
ing 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 spring suspensions for free movement of equalizer, condition of bushings,
torque of fasteners and for any type of cracking or damage to the spring leafs. Check air ride
suspensions for condition of bushings, air leaks, condition of shock absorbers, for proper opera-
tion of ride height leveling valve, and for proper inflation of the air springs.
NOTE: Never move an air ride trailer without first fully inflating 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
RELEASED. 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 TOA 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.
OPERATING INSTRUCTIONS

14
Date of Origin – 02/01/08
• Set parking brake on the tractor prior to loading the commodity onto the trailer.
• The trailer should be loaded evenly from front to rear, maintaining all state bridge laws.
DO NOT Overload the trailer as this action could void the trailer warranty.
• Use the air system air gauge (Air Ride only) to determine legal load conditions. Calibrate
the air gauge by comparing the gauge pressure to loaded trailer scale weight.
• The tarp bows can be swung to the side to facilitate loading as needed. Be sure to use a
safe, approved walkway or scaffold to reach and manipulate bows.
• Balance the load between front and rear hoppers.
• Roll the tarp closed and lock the crank handle into place before proceeding to another
location.
TRAILER UNLOADING
CAUTION! USE EXTREME CAUTION when attempting to dislodge commodity
through the trap doors during the unloading process as this could result in
serious personal injury or death.
• Position trailer at a point so commodity can be discharged properly and safely.
• Set parking brake on the tractor prior to discharging the commodity.
• Dump air bags (Air Ride only) prior to discharging commodity. Failure to discharge air
from lift bags when unloading could cause damage due to over extension of the
air bags and flexing of landing legs. This action could void the trailer warranty.
• Confirm discharge point is clear of any pedestrians or obstructions.
• Roll tarp to open position prior to unloading. Failure to open the tarp could result in
damage to tarp bows and trailer walls. This action could void trailer warranty.
• Open hopper trap doors, one at a time, to begin discharging commodity. Always Use
knockrails to assist with dislodging commodity.
• Confirm that all commodity has been discharged from both hoppers.
• Close trap doors, latch and lock, prior to departing to your next destination.
• Remove and properly store crank handle.
• Roll the tarp closed and lock the crank handle into place before proceeding to another
location.
• Inflate the air-ride suspension system prior to moving the trailer.
NOTE: Timpte trailers are designed to transport free flowing commodity. Knockrail and
pneumatic (air) hammer (vibrator) options are available to be installed to assist with
unloading commodity, if needed. Speak with a Timpte Sales Representative with any
question you may have with respect to knockrail and pneumatic (air) hammer options.
TRAILER LOADING
• Roll tarp to open position and lock crank handle in place,
• Check trap doors for closure, locks and latches for proper engagement before loading.
• Position trailer to receive commodity.

2 Speed Operators (Gear Reductions)
• Choose gear box mode you want to operate; direct drive or gear reduction. Drive nut
assembly without locking latch is the gear reduction side.
• Raise the locking latch to free the operator.
• Couple the socket end of the crank handle completely and securely over the hex drive nut on
the trap operator shaft.
• Rotate crank arm clockwise or counterclockwise to open trap door per instruction decal
(direction of rotation is dependent upon mode chosen). The crank handle swings in a large arc
so be sure the area is clear.
• Rotate crank arm opposite direction to close the trap door.
• Lower locking latch to lock the operator.
• Rear trap door operates opposite of front trap door.
Single Speed Trap Openers (Ratchet and Pawl)
• Couple the socket end of the crank handle completely and securely over the hex drive nut on
the trap operator shaft.
• On the front tub, rotate the crank handle slightly clockwise, this will release the pressure on the
ratchet pawl and allow you to rotate it out of the ratchet gear.
• Once the pressure on the pawl is released, rotate the pawl counterclockwise until it comes
to rest on the other side of the ratchet gear.
• Rotate the crank handle counterclockwise to open the trap door. The crank handle swings in a
large arc so be sure the area is clear.
• The door can be stopped at any point in the travel and the pawl will hold it from opening further.
• If you determine that you have opened the door too far and need to partly close the door to
meter the speed of the discharge, release and rotate the pawl back clockwise before rotating
the crank handle clockwise to close the door.
• Rear trap door operates opposite of front trap door.
TRAP DOOR OPERATION

16
Date of Origin – 02/01/08
• Use the trap door operator shaft to close the trap door.
• Locate a torque wrench onto the hex drive nut on the operator shaft.
• Rotate the wrench to close the trap door until the door is completely closed (decals).
• Locate the pawl lock to a position approximately 1/2 tooth away from the next gear ratchet
wheel locking position (pictured).
TRAP DOOR LATCH (PAWL) - Setup and Adjustment
• Rotate the torque wrench in the ‘close’ direction, torque wrench set point at 80 ft-lbs
(max), until pawl drops into gear ratchet wheel tooth to lock door closed. Pawl lock must be
set to drop into the gear ratchet wheel lock at a torque < or = 80 ft-lbs latching torque.
• Adjust pawl position side to side to fine-tune pawl latching torque set point.
• Release the door lock by rotating the operator shaft toward the ‘close’ direction, easing the
locking pressure on the pawl. Raise the pawl lock out of the ratchet wheel tooth and rotate the
pawl in the opposite direction. Open the trap door by rotating the operator shaft, with the crank
arm, opposite the ‘close’ direction (decals). Unlatching torque should not exceed 80 ft-lbs
torque.

17 Date of Origin – 02/01/08
NOTE
• The pawl lock should be centered on the gear ratchet, front to back, to assure proper
alignment between ratchet and pawl for locking.
• Use set screws, located in flange bearing (behind operator shaft mounting plate), to adjust
clearance for pawl and gear ratchet centering. (See figures below for clarification).
• Adjust the pawl and ratchet centering position as follows:
• Loosen adjustment set screws (2) to allow operator shaft/mounting plate
movement(in and out,push/pull).
• Confirm clearance between gear ratchet and mounting plate (push/pull)
• Adjust gear ratchet and pawl for centering (in and out movement, push/pull).
• Re-tighten set screws on flange bearing once centering and clearance are corrected.
DO NOT over-tighten set screws to avoid damage to operator shafts.
