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.

Date of Origin – 02/01/08

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

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

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

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.
