Wet stacking is a common problem with diesel engines which are operated for extended periods with light or no load applied. When a diesel engine operates without sufﬁ cient load (less than 40% of the rated output), it will not operate at its optimum temperature. This will allow unburned fuel to accumulate in the exhaust system, which can foul the fuel injectors, engine valves and exhaust system, including turbochargers, and reduce

Wet stacking does not usually cause any permanent

damage and can be alleviated if additional load is applied to relieve the condition. It can reduce the system performance and increase maintenance. Applying an increasing load over a period of time until the excess fuel is burned off and the system capacity is reached usually can repair the condition. This can take several

State Health Safety Codes and Public Resources Codes specify that in certain locations, spark arresters must be used on internal combustion engines that use hydrocarbon fuels. A spark arrester is a device designed to prevent accidental discharge of sparks or ﬂ ames from the engine exhaust. Spark arresters are qualiﬁ ed and rated by the United States Forest Service for this purpose. In order to comply with local laws regarding spark arresters, consult the engine distributor or the

GENERAL INFORMATION

The Multiquip models GBX24S (4-Spot LED) and GBX24B (LED balloon) are compact, mobile light towers that provide exceptional clear lighting for multiple applications found in: construction, emergency response, special events, security, and general large projection lighting challenges.

The GBX24S utilizes four powerful 600W LED lamps that are supported by industrial grade enclosures that withstand high impact and inclement weather. The LED assembly has a service life of 40,000 hours; and at full power, projects 399,000 lumens. An additional dimmer feature allows the operator to adjust the lamp projection that best supports the application. The four lamps are adjustable to inﬁnite angles and direction for optimum lighting orientation.

The GBX24B is designed with a powerful 2400W LED balloon lamp. The LED assembly has a service life of 40,000 hours; and at full power, projects 399,000 lumens of fully diffused lighting. An additional dimmer feature allows the operator to adjust the balloon output that best supports the application. The balloon utilizes an integrated fan that automatically inﬂates the unit in 20 seconds.

Both models are supported by a DOT/NHSTA qualiﬁed trailer that provides 4 adjustable jack stands, and a retractable tow bar. A ﬁve-section, anodized, aluminum mast assembly raises to a maximum height of 23 feet. The light tower cabinet assembly supports the 6.1 HP(4.6 kW) diesel engine, 3 kVA generator, control panel, and fuel tank. A lockable ﬂip-up rear hatch provides easy access to the engine/generator and fuel tank.

Safety precautions should be followed at all times when operating a trailer. Failure to read, understand and follow the safety guidelines could result in injury to yourself and others. Loss of control of the trailer or tow vehicle can result in death or serious injury.

COMMON CAUSES FOR LOSS OF TRAILER

 Driving too fast for the conditions (maximum speed when

towing a trailer is 55 mph).

 Overloading the trailer or loading the trailer unevenly.

 Trailer improperly coupled to the hitch.

 Not maintaining proper tire pressure.

 Not keeping lug nuts tight.

 Not properly maintaining the trailer structure.

 Ensure machine is towed level to tow vehicle.

TRAILER TOWING GUIDELINES

 Recheck the load tiedowns 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.

 Use your mirrors to verify that you have room to change

SAFETY GUIDELINES — TRAILERS

DRIVING CONDITIONS

When towing a trailer, you will have decreased acceleration, increased stopping distance, and increased turning radius (which means you must make wider turns to keep from hitting curbs, vehicles, and anything else that is on the inside corner). In addition, you will need a longer distance to pass, due to slower acceleration and increased length.



COUPLING TO THE TOW VEHICLE

Follow all of the safety precautions and instructions in this manual to ensure safety of persons, equipment, and satisfactory life of the trailer. Always use an adequate tow vehicle and hitch. If the vehicle or hitch is 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.

If you already have a tow vehicle, know your vehicle tow rating and make certain the trailer’s rated capacity is less than or equal to the tow vehicle’s rated towing capacity. If you already have (or plan to buy) a trailer, make certain that the tow rating of the tow vehicle is equal to or greater than that of the trailer.

The trailer VIN tag contains the critical safety information for the use of your trailer. Again, be sure your hitch and tow vehicle are rated for the Gross Vehicle Weight Rating of

your trailer.

Be alert for slippery conditions. You are more likely to be

affected by slippery road surfaces when driving a tow vehicle with a trailer, than driving a tow vehicle without a trailer.

Check rearview mirrors frequently to observe the trailer and trafﬁ c.

NEVER drive faster than what is safe.

WARNING

Driving too fast for severe road conditions can result in loss of control and cause death or serious injury.

Decrease your speed as road, weather, and lighting conditions deteriorate.

Always check for local trailer tow speed limits in your area.

WARNING

DO NOT transport people on the trailer. The transport

of people puts their lives at risk and may be illegal.

WARNING

Proper selection and condition of the coupler and hitch are essential to safely towing your trailer. A loss of coupling may result in death or serious injury.

• Be sure the hitch load rating is equal to or greater than the load rating of the coupler.

• Be sure the hitch size matches the coupler size.

• Observe the hitch for wear, corrosion and cracks before coupling. Replace worn, corroded or cracked hitch components before coupling the trailer to the tow vehicle.

• Be sure the hitch components are tight before coupling the trailer to the tow vehicle.

WARNING

An improperly coupled trailer can result in death or serious injury.

DO NOT move the trailer until:

• The coupler is secured and locked to hitch.

• The safety chains are secured to the tow vehicle.

• The trailer jack(s) are fully retracted.

DO NOT tow the trailer on the road until:

GBX24S/GBX24B LIGHT TOWER • OPERATION AND PARTS MANUAL — REV. #0 (05/30/19) — PAGE 45

• Tires and wheels are checked.

• The load is secured to the trailer.

• The trailer lights are connected and checked.

WARNING

Use of a hitch with a load rating less than the load rating of the trailer can result in loss of control and may lead to death or serious injury.

Use of a tow vehicle with a towing capacity less than the load rating of the trailer can result in loss of control, and may lead to death or serious injury.

Be sure your hitch and tow vehicle are rated for the Gross Vehicle Weight Rating of your trailer.

SAFETY GUIDELINES — TRAILERS

INOPERABLE LIGHTS OR MIRRORS

Be sure that all of the lights on your trailer are functioning properly before towing your trailer. Check the trailer taillights by turning on your tow vehicle headlights. Check the trailer brake lights by having someone step on the tow vehicle brake pedal while you look at trailer lights. Do the same thing to check the turn signal lights. See Trailer Wiring Diagram section in this manual.

Standard mirrors usually do not provide adequate visibility for viewing trafﬁ c to the sides and rear of a towed trailer. You must provide mirrors that allow you to safely observe approaching trafﬁ c.

TRAILER TOWING TIPS

Driving a vehicle with a trailer in tow is vastly different from driving the same vehicle without a trailer in tow. Acceleration, maneuverability and braking are all diminished with a trailer in tow.

It takes longer to get up to speed, you need more room to turn and pass, and more distance to stop when towing a trailer. You will need to spend time adjusting to the different feel and maneuverability of the tow vehicle with a loaded trailer.

Because of the signiﬁ cant differences in all aspects of maneuverability when towing a trailer, the hazards and risks of injury are also much greater than when driving without a trailer. You are responsible for keeping your vehicle and trailer in control, and for all the damage that is caused if you lose control of your vehicle and trailer.

As you did when learning to drive an automobile, ﬁ nd an open area with little or no trafﬁ c for your ﬁ rst practice trailering. Of course, before you start towing the trailer, you must follow all of the instructions for inspection, testing, loading and coupling. Also, before you start towing, adjust the mirrors so you can see the trailer as well as the area to the rear of it.

Drive slowly at ﬁ rst, 5 mph or so, and turn the wheel to get the feel of how the tow vehicle and trailer combination responds. Next, make some right and left hand turns. Watch in your side mirrors to see how the trailer follows the tow vehicle. Turning with a trailer attached requires

It will take practice to learn how to back up a tow vehicle with a trailer attached. Take it slow. Before backing up, get out of the tow vehicle and look behind the trailer to make

Some drivers place their hands at the bottom of the steering wheel, and while the tow vehicle is in reverse, “think” of the hands as being on the top of the wheel. When the hands move to the right (counterclockwise, as you would do to turn the tow vehicle to the left when moving forward), the rear of the trailer moves to the right. 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

If you are towing a bumper hitch rig, be careful not to allow the trailer to turn too much because it will hit the rear of the tow vehicle. To straighten the rig, either pull forward or turn

SAFETY CHAINS

If the coupler connection comes loose, the safety chains can keep the trailer attached to the tow vehicle. With properly rigged safety chains, it is possible to keep the tongue of the trailer from digging into the road pavement, even if the coupler-to-hitch connection comes apart.

JACKSTAND

A device on the trailer that is used to raise and lower the coupler. The jack is sometimes called the “landing gear” or the “tongue jack”.

COUPLER TYPES

The GBX24S and GBX24B come standard with a 2" ball coupler.

BALL COUPLER

A standard 2" ball coupler (Figure D) connects to a 2" ball hitch normally located on the bumper of the tow vehicle. All ball couplers come with a locking latch atop the coupler that must be engaged to ensure that the hitch ball is securely locked to the trailer coupler.

Before each tow, coat the ball with a thin layer of automotive bearing grease to reduce wear and ensure proper operation. Check the locking device that secures the coupler to the ball for proper operation.

If you see or feel evidence of wear, such as ﬂ at spots, deformations, pitting or corrosion, on the ball or coupler, immediately have your dealer inspect them to determine the proper action to prevent possible failure of the ball and coupler system. All bent or broken coupler parts must be

TIRE SAFETY

Unsafe Tires, Lug Nuts or Wheels

Trailer tires and wheels are more likely to fail than car tires and wheels because they carry a heavier load. Therefore, it is essential to inspect the trailer tires before each tow.

If a tire has a bald spot, bulge, cuts, is showing any cords, or is cracked, replace the tire before towing. If a tire has uneven tread wear, take the trailer to a dealer service center for diagnosis.

Uneven tread wear can be caused by tire imbalance, axle misalignment or incorrect inﬂ ation.

Tires with too little tread will not provide adequate tracking on wet roadways and can result in loss of control, leading to death or serious injury.

Improper tire pressure causes an unstable trailer and can result in a tire blowout and loss of control. Therefore, before each tow you must also check the tire pressure. Tire pressure must be checked when tires are cold.

Allow 3 hours cool-down after driving as much as 1 mile at 40 mph before checking tire pressure. Trailer tires will be inﬂ ated to higher pressures than passenger vehicle tires.

Since trailer wheels and lug nuts (or bolts) are subjected to greater side loads than automobile wheels, they are more prone to loosen. Before each tow, check to make sure they are tight.

The proper tightness (torque) for lug nuts is listed in the lug nut tightening section of this manual. Use a torque wrench to tighten the lug nuts. If you do not have a torque wrench, use a lug wrench (from your tow vehicle) and tighten the nuts as much as you can. Then have a service garage or trailer dealer tighten the lug nuts to the proper torque.

Lug nuts are also prone to loosen after first being assembled. When driving a new trailer (or after wheels have been remounted), check to make sure they are tight after the ﬁ rst 10, 25 and 50 miles of driving and before

Failure to perform this check can result in a wheel parting from the trailer and a crash, leading to death or serious

Determining the load limits of a trailer includes more than understanding the load limits of the tires alone.

There is a vehicle placard (Figure G) located in the same location as the certiﬁ cation label described above. This placard provides tire and loading information. In addition, this placard will show a statement regarding maximum cargo capacity.

If additional work items (hoses, tools, clamps etc.) are going to be added to the trailer, be sure they are distributed evenly to prevent overloading front to back and side to side. Heavy items should be placed low and as close to the axle positions as reasonable. Too many items on one side may overload a tire.

Excessive loads and/or underinﬂ ation cause tire overloading and, as a result, abnormal tire ﬂ exing occurs. This situation can generate an excessive amount of heat within the tire. Excessive heat may lead to tire failure. It is the air pressure that enables a tire to support the load, so proper inﬂ ation is critical. The proper air pressure may be found on the certiﬁ cation/VIN label and/or on the Tire and Loading Information placard. This value should never exceed the maximum cold inﬂ ation pressure stamped on the tire.

Perform the following steps to determine the load limit of your trailer.

Step 1.

Locate the statement, “The weight of cargo should never exceed XXX kg or XXX lbs.,” on your vehicle’s Tire and Loading Information placard (Figure G). This value equals the available amount of equipment load capacity.

Step 2.

Determine the weight of the equipment being loaded on the tow vehicle. That weight may not safely exceed the available equipment load capacity. The trailer’s Tire Information Placard is attached adjacent to or near the trailer’s VIN (Certiﬁ cation) label at the left front of the trailer (See Figure G).

Determining Load Limit of Tow Vehicle

Locate the statement, “The combined weight of occupants and cargo should never exceed XXX lbs.,” on your vehicle’s

Determine the combined weight of the driver and

Subtract the combined weight of the driver and passengers

Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage capacity calculated

If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult the tow vehicle’s manual to determine how this weight transfer reduces the

Studies of tire safety show that maintaining proper tire pressure, observing tire and vehicle load limits (not carrying more weight in your vehicle than your tires or vehicle can safely handle), avoiding road hazards and inspecting tires for cuts, slashes and other irregularities are the most important things you can do to avoid tire failure, such as tread separation or blowout and ﬂ at tires. These actions, along with other care and maintenance activities, can also:

resistance to heat. The temperature grade is for a tire that is inﬂ ated properly and not overloaded. Excessive speed, underinﬂ ation or excessive loading, either separately or in combination, can cause heat build-up and possible tire failure. From highest to lowest, a tire’s resistance to heat is graded as “A”, “B”, or “C”.

Refer to Figure I for additional tire information for light trucks.

Tires for light trucks have other markings besides those found on the sidewalls of passenger tires.

The proper repair of a punctured tire requires a plug for the hole and a patch for the area inside the tire that surrounds the puncture hole. Punctures through the tread can be repaired if they are not too large, but punctures to the sidewall should not be repaired. Tires must be removed from the rim to be properly inspected before being plugged

Replace the tire before towing the trailer if the tire treads have less than 1/16 inch depth or the telltale bands are visible. Check inﬂ ation pressure weekly during use to insure the maximum tire life and tread wear. A bubble, cut or bulge in a side wall can result in a tire blowout. Inspect both side walls of each tire for any bubble, cut or bulge; and replace

SAFETY GUIDELINES — TRAILERS

Table B below will help pinpoint the causes and solutions of tire wear problems.

Wheel Rims

If the trailer has been struck, or impacted, on or near the wheels, or if the trailer has struck a curb, inspect the rims for damage (i.e. being out of round); and replace any damaged wheel. Inspect the wheels for damage every year, even if no obvious impact has occurred.

Wheels, Bearings and Lug Nuts

A loose, worn or damaged wheel bearing is the most common cause of brakes that grab.

To check wheel bearings, jack trailer and check wheels for side-to-side looseness. If the wheels are loose, or spin with a wobble, the bearings must be serviced or replaced. Check inﬂ ation pressure weekly during use to insure the maximum tire life and tread wear. Most trailer axles are built with sealed bearings that are not serviceable. Sealed bearings must be replaced as complete units.

It is extremely important to apply and maintain proper wheel mounting torque on the trailer. Be sure to use only the fasteners matched to the cone angle of the wheel. Proper

Center Wear Over inﬂ ation.

Adjust pressure to particular load per tire manufacturer.

Edge Wear Under inﬂ ation.

Side Wear

Toe Wear Incorrect toe-in. Align wheels.

Cupping Out-of-balance.

Wheel lockup and tire skidding.

Adjust pressure to particular load per tire manufacturer.

Make sure load does not exceed axle rating. Align wheels.

Check bearing adjustment and balance tires.

Avoid sudden stops when possible and adjust brakes.

WARNING

ALWAYS wear safety glasses when removing or installing force ﬁ tted parts. DO NOT attempt to repair or modify a wheel. DO NOT install an inner-tube to correct a

leak through through the rim. If the rim is cracked, the air pressure in the inner tube may cause pieces of the rim to explode (break off) with great force and cause serious eye or bodily injury.

Lug nuts are prone to loosen after initial installation, which can lead to death or serious injury. Check all wheel lug nuts periodically.

Lug Nut Torque Requirements

procedure for attachment of the wheels is as follows:

1. Start all wheel lug nuts by hand.

2. Torque all lug nuts in sequence. See Figure J.

by Table C.

NOTICE

NEVER use an pneumatic air gun to tighten wheel lug nuts.

Over-tightening lug nuts will result in breaking the studs or permanently deforming the mounting stud holes in the wheels.

Lights and Signals

Before each tow, check the trailer taillights, stoplights, turn signals and any clearance lights for proper operation.

Replace any broken or burned-out lamps as necessary. Check the wire harness for cuts, fraying or other damage. If it needs replacing, contact your dealer.
