SECTION 1 - SAFETY PRECAUTIONS SECTION 1. SAFETY PRECAUTIONS 1.1 SAFETY INFORMATION 1.3 MAJOR HAZARDS Safety Information, 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. Therefore, 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.
SECTION 1 - SAFETY PRECAUTIONS Anticipate the trailer “swaying.” Swaying is the trailer reaction to the air pressure wave caused by passing trucks and busses. Continued pulling of the trailer provides a stabilizing force to correct swaying. Do not apply the brakes to correct trailer swaying. Check rear view mirrors frequently to observe the trailer and traffic. Use lower gear when driving down steep or long grades. Use the engine and transmission as a brake.
SECTION 1 - SAFETY PRECAUTIONS TRAILER TIRES WILL BE INFLATED TO HIGHER PRESSURES THAN PASSENGER VEHICLE TIRES. UNDER-INFLATED FRONT TIRES ON THE TOWING VEHICLE COULD CAUSE STEERING PROBLEMS. LOW PRESSURE IN THE REAR TIRES OF THE TOWING VEHICLE COULD CAUSE THE VEHICLE TO SWAY. Trailer wheels and lug nuts are subjected to significant side loads during tow. Before each tow, visually inspect the lug nuts for loosening.
SECTION 1 - SAFETY PRECAUTIONS 2 1 1. VIN Label 2. Tire Information Label Figure 1-1. VIN Label & Tire Information Label Unsafe Load Distribution Uneven load distribution can cause tire, wheel, axle or structural failure. Be sure your trailer is properly loaded. A proper weight distribution is equal, right to left; and creates a tongue weight that is in the proper range for stable trailer handling (between 10-15% of the total weight of the cargo and the trailer).
SECTION 1 - SAFETY PRECAUTIONS Standard mirrors usually do not provide adequate visibility for viewing traffic to the sides and rear of towed trailer. You must provide mirrors that allow you to safely observe approaching traffic. Modifying the Trailer Essential safety items can be damaged by altering your trailer. Even simply driving a nail or screw to hang something can damage an electrical circuit, hydraulic line or other feature of the trailer.

SECTION 2 - TRAILER OPERATION SECTION 2. TRAILER OPERATION 2.1 TRAILER MODELS Triple-L™ Trailers employ a unique trailer deck design to make loading and unloading easier. The trailer deck can be lowered to the ground while remaining level, allowing equipment to be rolled or driven directly onto the trailer deck. Table 2-1.
SECTION 2 - TRAILER OPERATION Production Option and Accessory Weights Any time a trailer is equipped with a production option or accessory or one of these components is added to a trailer, the weights listed in the following table must be subtracted from the rated vehicle capacity weight. NOTE: The specified options and accessories must be considered part of cargo weight.

SECTION 2 - TRAILER OPERATION 2.2 TRAILER FEATURES 1. Rails (Not Shown) - These surround the front and sides of the deck and provide a means to aid in the proper placement of cargo. 2. Storage - This compartment is used to secure the owners manual, tools and other items. 15. Serial Number - This is a 17 digit number, also referred to as the Vehicle Identification Number (VIN), that can be found on the identification plate and stamped on the frame of the trailer. 16.
SECTION 2 - TRAILER OPERATION 2.3 GENERAL 2.4 COUPLER Trailer VIN Information The Trailer Features figure shows the location of the Trailer Identification Plate on your trailer. Mfd. By: JLG Industries, Inc - McConnellsburg, PA--USA Phone 877-JLG-LIFT DATE MODEL PNBV/GVWR (kg/lb) RIMS PNBE/GAWR (ea.axle)(kg/lb) TIRES INFL C (KPa/psi) THIS VEHICLE CONFORMS TO ALL APPLICABLE U.S. FEDERAL MOTOR VEHICLE SAFETY STANDARDS IN EFFECT ON THE DATE OF MANUFACTURE. V.I.N. No.
SECTION 2 - TRAILER OPERATION 2.6 BATTERY (OPTION) . Battery The battery is carried on the trailer and is used for powering the motor running the hydraulic pump. If the trailer has electric brakes, this same battery is used for power to the break-away switch. Batteries are considered an optional item which can be purchased with the trailer or obtained locally. The battery should be a 12 volt deep cycle.
SECTION 2 - TRAILER OPERATION 2.8 TOW VEHICLE AND HITCH INFORMATION Coupler Height Adjustment Follow all of the safety precautions and instructions in this manual and the manuals of the tow vehicle and the hitch to ensure safety of persons, cargo, and satisfactory life of the trailer. Remove the bolts securing the coupler to the mounting bracket. Move the coupler up of down to desired height. Secure with the bolts. For the Pintle Hitch Coupler, torque the two bolts to 225 ft lb (305 Nm).
SECTION 2 - TRAILER OPERATION Automatic Transmission Oil Cooler The automatic transmission of a towing vehicle handles more power when a trailer is being towed. Inadequate cooling will shorten transmission life, and may result in sudden transmission failure. Ask the tow vehicle dealer if it is necessary to install a separate oil cooler for the automatic transmission. Fire Extinguisher A fire extinguisher should be carried in the tow vehicle.
SECTION 2 - TRAILER OPERATION 2. Raise the bottom surface of the coupler to be above the top of the hitch ball. Use the tongue jack if one is provided; otherwise, use wood or concrete blocks to support the trailer tongue. 3. As seen in Figure 2-3., Coupler, slide the collar on the hitch toward the trailer until it opens up to accept the ball from the tow vehicle. 4. Once the hitch on the trailer is open, align the tow vehicle up with the trailer hitch. 5.
SECTION 2 - TRAILER OPERATION Connect the Electrical Cables TO AVOID POSSIBLE INJURY DO NOT TOW THE TRAILER WITH THE PULLPIN REMOVED AND THE BREAKAWAY BRAKE SYSTEM ON BECAUSE THE BRAKES WILL OVERHEAT WHICH CAN RESULT IN PERMANENT BRAKE FAILURE. Connect the trailer lights to the tow vehicle's electrical system using the electrical connectors. Check all lights for proper operation: a. Clearance and Running Lights (Turn on tow vehicle headlights).
SECTION 2 - TRAILER OPERATION 2.10 LOADING THE TRAILER Improper trailer loading causes many accidents and deaths. To safely load a trailer, you must consider: a. Overall load weight For a ball hitch trailer the tongue weight should be between 10% and 15% of the total trailer weight, including the cargo. For example, a trailer, with a loaded weight of 4,000 pounds, should have 10-15% of 4,000 pounds on the tongue. That is, the trailer would have 400 to 600 pounds on its tongue. b.
SECTION 2 - TRAILER OPERATION DO NOT TRANSPORT FLAMMABLE, EXPLOSIVE, POISONOUS OR OTHER DANGEROUS MATERIALS IN YOUR TRAILER. EXCEPTIONS ARE: FUEL IN THE TANKS OF EQUIPMENT BEING HAULED, FUEL STORED IN THE TANK OF AN ON-BOARD GENERATOR. Preparing the Trailer for Loading Before loading cargo onto the trailer: Chock wheels on the left and right sides of the trailer to prevent movement to the front or rear while loading.
SECTION 2 - TRAILER OPERATION NOTE: Be sure that the deck is lowered to seat the weight of the deck on the latch and not the cylinder. BEFORE TOWING THE TRAILER, ENSURE THAT THE TRAVEL LATCH HAS PROPERLY LATCHED INTO PLACE. TIE DOWN ALL LOADS WITH PROPER SIZED FASTENERS, ROPES, STRAPS, ETC. IF YOUR TRAILER IS ENCLOSED OR EQUIPPED WITH AN OPTIONAL TAILGATE, THE DOORS OR TAILGATE MUST BE SECURELY LATCHED BEFORE TOWING THE TRAILER.
SECTION 2 - TRAILER OPERATION 2.11 LIFT TIE DOWN PROCEDURE 2.12 TOWING OPERATIONS The tie downs at the front of the trailer are a fixed length and remain attached to the D-rings in the front corners of the deck. 1. Move the lift onto the trailer and pull forward until the front chains can be attached to the designated tie down points on the lift. THERE SHOULD BE 15 INCHES FROM THE INSIDE FRONT OF THE TRAILER WALL BACK TO THE CENTER OF THE FRONT WHEEL OF THE LIFT. 2.
SECTION 2 - TRAILER OPERATION Safe Trailer Towing Guidelines • Recheck the load tie downs to make sure the load will not shift during towing. • Before towing, check coupling, safety chain, safety brake, tires, wheels and lights. • Check the lug nuts or bolts for tightness. • Check coupler tightness after towing 50 miles. • When equipped with electric brakes, adjust the brake controller to engage the trailer brakes before the tow vehicle brakes. Your dealer can assist you by making this adjustment.
SECTION 2 - TRAILER OPERATION 2.13 PRE-TOW INSPECTION 10. Trailer Battery - Charged and capable of raising trailer deck. Prior to each tow, a Pre-Tow Inspection must be performed. Check each item as specified in the checklist below. 11. Hydraulic Pump - Free of Leaks. Reservoir level full. Proper operation. 12. Deck Descent Alarm - Activates when deck is lowered. DO NOT OVERLOOK VISUAL INSPECTION OF CHASSIS UNDERSIDE.
SECTION 2 - TRAILER OPERATION 2.14 BREAKING-IN A NEW TRAILER Synchronizing the Brake Systems Retighten Lug Nuts at First 10, 25 & 50 Miles Wheel lugs can shift and settle quickly after being first assembled, and must be checked after the first 10, 25 and 50 miles of driving. Failure to perform this check could result in a wheel coming loose from the trailer, causing a crash leading to death or serious injury.

SECTION 4 - SERVICE AND MAINTENANCE 4.12 TIRE AND WHEEL MAINTENANCE Checking Tire Pressure Glossary of Tire and Loading Terminology It is important to check your vehicle's tire pressure at least once a month for the following reasons: 1. Cold Inflation Pressure - The pressure in the tire before you drive. The term cold does not relate to the outside temperature. Rather, a cold tire is one that has not been driven on for at least three hours. • Most tires may naturally lose air over time. 2.
SECTION 4 - SERVICE AND MAINTENANCE Tire Wear Replace the tire before towing the trailer, if the tire treads have less than 1/16-inch depth or the telltale bands are visible. The following tire wear diagnostic chart will help you pinpoint the causes and solution of tire wear problems. The following tire wear diagnostic chart will help you pinpoint the causes and solution of tire wear problems. A bubble, cut or bulge in a sidewall can result in a tire blowout.

SECTION 4 - SERVICE AND MAINTENANCE Lug Nuts 25 and 50 miles of driving and visually inspect before each tow thereafter. It is extremely important to apply and maintain proper wheel mounting torque on the trailer axle. Torque wrenches are the best method to ensure the proper amount of torque is being applied to a nut. NOTE: Wheel nuts must be installed and maintained at the proper torque to prevent loose wheels, broken studs, and possible dangerous separation of wheel from the axle.
SECTION 4 - SERVICE AND MAINTENANCE 4.13 TIRE SAFETY INFORMATION NOTE: This portion of the User’s Manual contains tire safety information as required by 49 CFR 575.6. Steps For Determining Correct Load Limit – Trailer pressure that enables a tire to support the load, so proper inflation is critical. The proper air pressure may be found on the certification/VIN label and/or on the Tire Placard. This value should never exceed the maximum cold inflation pressure stamped on the tire.
SECTION 4 - SERVICE AND MAINTENANCE Steps For Determining Correct Load Limit – Tow Vehicle 1. Locate the statement, “The combined weight of occupants and cargo should never exceed XXX lbs.,” on your vehicle’s placard. 2. Determine the combined weight of the driver and passengers who will be riding in your vehicle. 3. Subtract the combined weight of the driver and passengers from XXX kilograms or XXX pounds. 4. The resulting figure equals the available amount of cargo and luggage capacity.
SECTION 4 - SERVICE AND MAINTENANCE Safety First – Basic Tire Maintenance Properly maintained tires improve the steering, stopping, traction, and load-carrying capability of your vehicle. Under-inflated tires and overloaded vehicles are a major cause of tire failure. Therefore, as mentioned above, to avoid flat tires and other types of tire failure, you should maintain proper tire pressure, observe tire and vehicle load limits, avoid road hazards, and regularly inspect your tires.
SECTION 4 - SERVICE AND MAINTENANCE Information On Passenger Tires Tire Tread The tire tread provides the gripping action and traction that prevent your vehicle from slipping or sliding, especially when the road is wet or icy. In general, tires are not safe and should be replaced when the tread is worn down to 1/16 of an inch. Tires have built-in treadwear indicators that let you know when it is time to replace your tires.
SECTION 4 - SERVICE AND MAINTENANCE Speed Rating The speed rating denotes the speed at which a tire is designed to be driven for extended periods of time. The ratings range from 99 miles per hour (mph) to 186 mph. These ratings are listed below. Note: You may not find this information on all tires because it is not required by law.
SECTION 4 - SERVICE AND MAINTENANCE Tire Safety Tips Glossary Of Tire Terminology Preventing Tire Damage • Slow down if you have to go over a pothole or other object in the road. • Do not run over curbs or other foreign objects in the roadway, and try not to strike the curb when parking. Tire Safety Checklist • Check tire pressure regularly (at least once a month), including the spare. • Inspect tires for uneven wear patterns on the tread, cracks, foreign objects, or other signs of wear or trauma.
SECTION 4 - SERVICE AND MAINTENANCE Gross Axle Weight Rating The maximum weight that any axle can support, as published on the Certification / VIN label on the front left side of the trailer. Actual weight determined by weighing each axle on a public scale, with the trailer attached to the towing vehicle. Gross Vehicle Weight Rating The maximum weight of the fully loaded trailer, as published on the Certification / VIN label.
