MAINTENANCE BASIC INSPECTION AND MAINTENANCE See Table 7 below for a general inspection and maintenance checklist. For more detailed maintenance, refer to the engine service manual. Table 7.
MAINTENANCE GENERAL INSPECTION Service Daily Prior to each use, the light tower should be cleaned and inspected for deficiencies. Check for loose, missing or damaged nuts, bolts or other fasteners. Also check for fuel or oil leaks. If engine is operating in very dusty and dry grass conditions, a clogged air cleaner will result in high fuel consumption, loss of power and excessive carbon buildup in the combustion chamber.
MAINTENANCE 6. Adjust the flow of the water flowing in and draining out to ensure that the radiator is always full during the flushing operation. While flushing water through the system, make sure the water inlet hose does not come out of the radiator filler port. 7. After flushing, stop the engine, open drain plug and drain the water, then close drain plugs. 8. After draining the water, flush the system with a flushing agent. See instructions on flushing agent label. 9.
MAINTENANCE CHECK CABLE WEAR The wire rope (cable) that raises and extends the mast is a very important part of the light tower. There is one cable/ hand winch system, located on the tongue of the trailer, that raises and extends the light tower mast. There is a second cable/hand winch system located on the mast that serves to raise and lower the two extendable sections of the mast. DANGER Wire rope (cable) will fail if it is worn, frayed, misused, crushed, kinked or damaged in any way.
MAINTENANCE 6. Route the upper mast cable through the center mast pulley and connect the free end of the cable to the lower mast ankle shackle. Route the center mast cable through the lower mast pulley and connect the free end of the cable to the hand winch at the bottom of the lower mast. 7. Raise, extend, retract and lower the mast several times to verify correct operation. STORAGE For storage for over 30 days, the following is required: Fill the fuel tank completely.
MAINTENANCE — TRAILERS The following trailer maintenance guidelines are intended to assist the operator in preventive maintenance. ADJUSTABLE CHANNEL frequently, at least every six months and prior to use. Follow the steps below to disassemble the wheel hub and service the wheel bearings. See Figure 22. BEARING Your trailer may be equipped with an adjustable channel (Figure 21) that allows the coupler to be raised or lowered to a desired height.
MAINTENANCE — TRAILERS DANGER NEVER crawl under the trailer unless it is on firm and level ground and resting on properly placed and secured jackstands. The possibility exists of the trailer falling thus causing equipment damage and severe bodily harm even death! LEAF SUSPENSION The leaf suspension springs and associated components (Figure 23) should be visually inspected every 6,000 miles for signs of excessive wear, elongation of bolt holes, and loosening of fasteners.

TRAILER GUIDELINES The following guidelines are intended to assist the operator in the operation and handling of a trailer. Shift your automatic transmission into a lower gear for city driving. 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.
TRAILER GUIDELINES 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. Be alert for slippery conditions.
TRAILER GUIDELINES INOPERABLE BRAKES, LIGHTS OR MIRRORS Be sure that the brakes and 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.
TRAILER GUIDELINES To determine the “empty” or “net” weight of your trailer, weigh it on an axle scale. To find the weight of the trailer using an axle scale, you must know the axle weights of your tow vehicle without the trailer coupled. Some of the trailer weight will be transferred from the trailer to the tow vehicle axles, and an axle scale weighs all axles, including the tow vehicle axles. VIN TAG VIN TAG Figure B.
TRAILER GUIDELINES 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”.
TRAILER GUIDELINES WARNING Lower the trailer (Figure D) until the coupler fully engages the hitch ball. A worn, cracked or corroded hitch ball can fail while towing and may result in death or serious injury. 2-INCH TRAILER COUPLER TOW VEHICLE Before coupling trailer, inspect the hitch ball for wear, corrosion and cracks. Replace worn or damaged hitch ball. 2-INCH BALL WARNING A loose hitchball nut can result in uncoupling, leading to death or serious injury.
TRAILER GUIDELINES Attaching Safety Chain Backup Lights (place tow vehicle gear shift in reverse). Visually inspect the safety chains and hooks for wear or damage. Replace worn or damaged safety chains and hooks before towing. Turn Signals (activate tow vehicle directional signal lever). Attach the safety chains so that they: • Cross underneath the coupler. See Figure E.
TRAILER GUIDELINES PINTLE HITCH COUPLER A pintle eye coupler (Figure F) connects to a pintle-hook hitch that is located on or under the rear bumper of the tow vehicle. This system of coupling a trailer to a tow vehicle is sometimes referred to as a “lunette eye, tow ring or G.I. hitch.
TRAILER GUIDELINES Raise the bottom surface of the coupler to be above the top of the pintle hitch hook. Use the tongue jackstand to support the trailer tongue. Wood or concrete blocks may also be used. WARNING Lower the trailer so that its entire tongue weight is held by the hitch. Raise the jackstand to a height where it will not interfere with the road. TIRE SAFETY A defective pintle hitch not properly fastened can result in uncoupling, leading to death or serious injury.
TRAILER GUIDELINES 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. WARNING Metal creep between the wheel rim and lug nuts will cause rim to loosen and could result in a wheel coming off, leading to death or serious injury. Tighten lug nuts before each tow. Lug nuts are also prone to loosen after first being assembled.
TRAILER GUIDELINES 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 (Certification) label at the left front of the trailer (See Figure I). along with other care and maintenance activities, can also: Locate the statement, “The combined weight of occupants and cargo should never exceed XXX lbs.
TRAILER GUIDELINES 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. in the tire. In general, the greater the number of plies, the more weight a tire can support. Tire manufacturers also must indicate the materials in the tire, which include steel, nylon, polyester, and others. Next number: This two- or three-digit number is the tire’s load index.
TRAILER GUIDELINES Tires for light trucks have other markings besides those found on the sidewalls of passenger tires. LT: The “LT” indicates the tire is for light trucks or trailers. 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.
TRAILER GUIDELINES 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. 3.
