Safety 2. Safety 2.1 Safety Alert Symbols And Signal Words An Owner’s Manual that provides general trailer information cannot cover all of the specific details necessary for the proper combination of every trailer, tow vehicle and hitch. You must read, understand and follow the instructions given by the tow vehicle and trailer hitch manufacturers, as well as the instructions in this manual. Our trailers are built with components produced by various manufacturers.
Safety 2.2.4 Trailer Not Properly Coupled To Hitch ^ WARNING It is critical that the trailer be securely coupled to the hitch, and that the safety chains and emergency breakaway brake lanyard are correctly attached. Uncoupling may result in death or serious injury to you and to others. Driving too fast for conditions can result in loss of control and cause death or serious injury. Adjust speed down when towing trailer. ^ WARNING 2.2.
Safety 2.2.5 Proper Use Of Safety Chains Safety chains are provided so that control of the trailer can be maintained if your trailer comes loose from the hitch. ^ WARNING 2.2.7 Matching Trailer And Hitch ^ DANGER Be sure hitch and tow vehicle are rated for the Gross Vehicle Weight Rating (GVWR) of your trailer. Improper rigging of the safety chains can result in loss of control of the trailer and tow vehicle, leading to death or serious injury, if the trailer uncouples from the tow vehicle.
Safety ^ WARNING Inflate tires to pressure stated on the Certification / VIN label. Improper tire pressure may cause unstable trailer. Blowout and loss of control may occur. Death or serious injury can result. Make sure of proper tire pressure before towing trailer. The tightness of the wheel nuts or bolts is very important in keeping the wheels properly seated to the hub. Before each tow, check to make sure they are tight.
Safety 2.2.10 Unsafe Load Distribution Improper front / rear load distribution can lead to an unstable trailer or poor tow vehicle handling. Poor trailer stability results from tongue weights that are too low, and poor tow vehicle stability results from tongue weights that are too high. Refer to the “Loading And Unloading” section for more information.
Safety 2.2.12 Inappropriate Cargo ^ WARNING The trailer may be designed for specific cargo. If your trailer is designed for specific cargo, only carry that cargo in the trailer. A trailer must not be used to carry certain items, such as people, containers of hazardous substances or containers of flammable substances. Improper electrical connection between the tow vehicle and the trailer will result in inoperable lights and electric brakes, and can lead to collision.
Safety ^ DANGER NEVER alter or substitute any hydraulic system component. Death or serious injury may result. An altered or component substituted hydraulic system may malfunction, resulting in the dump body falling without warning. NEVER alter or substitute any hydraulic system component. ^ WARNING Electrocution hazard. Dump body coming near or contacting power lines can cause electrocution. Electrocution can occur without contact.
Safety Conversely, rotating the steering wheel clockwise with your hands at the bottom of the wheel will move the rear of the trailer to the left, while backing up. Be careful not to allow the trailer to turn too much, because it will hit the rear of the tow vehicle.

Tire Safety 3. Tire Safety Information 3.1 Trailer Tire Information This portion of the User’s Manual contains tire safety information as required by 49 CFR 575.6. Trailer tires may be worn out even though they still have plenty of tread left. This is because trailer tires have to carry a lot of weight all the time, even when not in use. Section 3.1 contains “Trailer Tire Information”. Section 3.2 contains “Steps for Determining Correct Load Limit - Trailer”. Section 3.
Tire Safety after five years, trailer tires are considered worn out and should be replaced, even if they have had minimal or no use. This is such a general statement that it may not apply in all cases. It is best to have your tires inspected by a tire supplier to determine if your tires need to be replaced. If you are storing your trailer for an extended period, make sure the tires are fully inflated to the maximum rated pressure and that you store them in a cool, dry place, such as a garage.
Tire Safety 3.3 Steps For Determining Correct Load Limit - Tow Vehicle 1. Locate the statement, “The combined weight of 2. 3. 4. 5. 6. occupants and cargo should never exceed XXX lbs.,” on your vehicle’s placard. Determine the combined weight of the driver and passengers who will be riding in your vehicle. Subtract the combined weight of the driver and passengers from XXX kilograms or XXX pounds. The resulting figure equals the available amount of cargo and luggage capacity.
Tire Safety is higher or deeper than the same molding on the other sidewall of the tire or the outward facing sidewall of an asymmetrical tire that has a particular side that must always face outward when mounted on a vehicle. Light truck (LT) tire: A tire designated by its manufacturer as primarily intended for use on lightweight trucks or multipurpose passenger vehicles. May be used on trailers. Load rating: The maximum load that a tire is rated to carry for a given inflation pressure.
Tire Safety Rim diameter: This means the nominal diameter of the bead seat. Rim size designation: This means the rim diameter and width. Rim type designation: This means the industry of manufacturer’s designation for a rim by style or code. Rim width: This means the nominal distance between rim flanges. Section width: The linear distance between the exteriors of the sidewalls of an inflated tire, excluding elevations due to labeling, decoration, or protective bands.

Use this information to make tire safety a regular part of your vehicle maintenance routine. Recognize that the time you spend is minimal compared with the inconvenience and safety consequences of a flat tire or other tire failure. 3.5.1 Safety First- Basic Tire Maintenance Properly maintained tires improve the steering, stopping, traction, and load-carrying capability of your vehicle.
Tire Safety tire pressure. These “missing” pounds of pressure are what you will need to add. 5. At a service station, add the missing pounds of air pressure to each tire that is under inflated. 6. Check all the tires to make sure they have the same air pressure except in cases in which the front and rear tires are supposed to have different amounts of pressure).
Tire Safety Numbers of 70 or lower indicate a short sidewall for improved steering response and better overall handling on dry pavement. R: The “R” stands for radial. Radial ply construction of tires has been the industry standard for the past 20 years. Next number: This two-digit number is the wheel or rim diameter in inches. If you change your wheel size, you will have to purchase new tires to match the new wheel diameter. Next number: This two- or three-digit number is the tire’s load index.
Tire Safety ST: An “ST” is an indication the tire is for trailer use only. Max. Load Dual kg (lbs) at kPa (psi) Cold: This information indicates the maximum load and tire pressure when the tire is used as a dual, that is, when four tires are put on each rear axle (a total of six or more tires on the vehicle). Max. Load Single kg (lbs) at kPa (psi) Cold: This information indicates the maximum load and tire pressure when the tire is used as a single.
Coupling To Tow Vehicle 4. Coupling To Tow Vehicle Follow all of the safety precautions and instructions in this manual to ensure safety of persons, cargo, and satisfactory life of the trailer. 4.1 Tow Vehicle And Hitch If the vehicle and hitch are not properly selected and matched to the Gross Vehicle Weight Rating (GVWR) of your trailer, you can cause an accident that could lead to death or serious injury.
Coupling To Tow Vehicle Hitch: The connecting mechanism including the ball support platform and ball and those components that extend and are attached to the towing vehicle, including bumpers intended to serve as hitches. Safety chains: Chains permanently attached to the trailer such that if the coupler connection comes loose, the safety chains can keep the trailer attached to the tow vehicle.
Coupling To Tow Vehicle 4.3.1.1 Before Coupling Trailer To Tow Vehicle 1. Be sure the size and rating of hitch ball match the size and rating of the coupler. Hitch balls and couplers are marked with their size and rating. ^ WARNING Coupler-to-hitch mismatch can result in uncoupling, leading to death or serious injury. Be sure the LOAD RATING of the hitch ball is equal or greater than the load rating of the coupler. 6. Raise the bottom surface of the coupler to be above the top of the hitch ball. 4.3.1.
Coupling To Tow Vehicle 6. Lower the trailer so that its entire tongue weight is held by the hitch, and continue retracting the jack to its fully retraced position. ^ CAUTION ^ WARNING Ring-to-pintle mismatch can result in uncoupling, leading to death or serious injury. Drop leg jacks may be spring loaded and may rapidly return to the raise position when released. Be sure the LOAD RATING of the pintle is equal or greater than the load rating of the ring. Keep clear when releasing drop legs.
Coupling To Tow Vehicle 2. Remove the safety latch pin and open the pintle ^ CAUTION locking mechanism. 3. In the open position, the ring is able to drop fully onto the pintle. Drop leg jacks may be spring loaded and may rapidly return to the raise position when released. Keep clear when releasing drop legs. 7. Fully retract jack drop leg if equipped. Go to Section 4.3.3 “Connect Safety Chains” to continue connecting trailer to tow vehicle. 4.
Coupling To Tow Vehicle ^ WARNING Improper rigging of the safety chains can result in loss of control of the trailer and tow vehicle, leading to death or serious injury, if the trailer uncouples from the tow vehicle. Connect the lanyard to the tow vehicle so that the hydraulic actuator will engage or the electric brake pullpin will be pulled out before all of the slack in the safety chains is taken up. Do not connect the lanyard to a safety chain, hitch ball or hitch ball assembly.
Coupling To Tow Vehicle Most trailers are setup to charge the battery from the tow vehicle. If the electrical system on your tow vehicle does not provide power to the battery, you must periodically charge the battery with a commercial battery charger to keep the battery charged. ^ CAUTION ^ WARNING An ineffective breakaway brake system can result in a runaway trailer, leading to death or serious injury if the coupler fails. Test the function of the breakaway brake system before towing trailer.
Coupling To Tow Vehicle 4.3.5.3 Test Surge Brakes Hydraulic surge actuator systems provide automatic and smooth trailer braking without special application by the tow vehicle driver. While this is extremely convenient it can sometimes be difficult to determine if the surge setup is functioning properly. The following steps provide a quick field-test to confirm that the trailer brake system is operational.
Coupling To Tow Vehicle 4.5 Tongue Weight It is critical to have a portion of the trailer load carried by the tow vehicle. That is, the trailer tongue must exert a downward force on the hitch. This is necessary for two reasons. First, the proper amount of tongue weight is necessary for the tow vehicle to be able to maintain control of the tow vehicle/trailer system.
Coupling To Tow Vehicle 4.6 Adjust Hitch Height (If Equipped) The height of the hitch on the trailer must be adjusted so that the trailer, when loaded to rated capacity, is level while connected to the tow vehicle. A level trailer allows equal weight distribution on the axles. Your dealer or a trailer service center can perform this adjustment or you can use the following steps to adjust the hitch height yourself.
Loading And Unloading 5. Loading And Unloading Improper trailer loading causes many accidents and deaths. To safely load a trailer, you must consider: • Overall load weight. • Load weight distribution. • Proper tongue weight. • Securing the load properly. To determine that you have loaded the trailer within its rating, you must consider the distribution of weight, as well as the total weight of the trailer and its contents.
Loading And Unloading ^ WARNING Electrocution hazard. Dump body coming near or contacting power lines can cause electrocution. Electrocution can occur without contact. Verify there are no overhead power lines over or near the trailer before raising dump body. ^ WARNING A soft and/or uneven surface may cause tow vehicle and trailer to tip over when dump body is raised. Raise dump body ONLY if tow vehicle and trailer are both on a firm and level surface. 5.
Loading And Unloading NOTICE Ramps are not rated for load bearing capacity. They will NOT support the load bearing capacity of the trailer. Do not overload ramps. 4. Load equipment into trailer. 5.3 Loading And Unloading Bulk Material Check if the trailer has “payload” decals. If not, then determine the payload, or cargo capacity, by subtracting the empty weight of the trailer from the GVWR given on the Certification / VIN tag.
Loading And Unloading ^ WARNING Unsecured rear doors can cause a driving hazard. Do not operate trailer without properly securing rear door latches. 5.3.2 Loading Bulk Material 1. Tell the loader operator the payload of your trailer. 2. 3. 4. 5. The loader operator will have an approximate weight of the material to be loaded. Use common sense when loading. If you are uncertain of the weight of the material, load a small amount and weigh your trailer.
