REPORTING SAFETY DEFECTS

If you believe that your vehicle has a defect that could cause a crash or could cause injury or death, you should immediately inform the National Highway Traffic Safety Administration (NHTSA) in addition to notifying Multiquip at 1-800-421-1244. If NHTSA receives similar complaints, it may open an investigation, and if it finds that a safety defect exists in a group of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become involved in individual problems between you, your dealer, or Multiquip. To contact NHTSA, you may either call the Vehicle Safety Hotline toll-free at 1-888-327-4236 (TTY: 1-800-424-9153), go to http://www.nhtsa.dot.gov; or write to:

For ease of service or transport, each floodlight is equipped with a quick-disconnect connector that allows the lamp fixture to be removed quickly. This feature is extremely useful during transport of the light tower over rough terrain. It is always best to remove the floodlights and pack them safely so they will not get damaged.

As an added feature, the LT-12 is available with two auxiliary output receptacles. The upper most receptacle(twist-lock), located at the front of the light tower, can provide 240 VAC at 25 amps. The bottom receptacle is a GFCI receptacle which can supply 120 VAC at 15 amps. These receptacles that can be used for light power tools or other similar applications.

NOTE

Some LT-12 Light towers are equipped with a Lombardini Diesel Engine. All procedures & references to Deutz engines in this manual may be applied to Lombardini engines unless specifically noted otherwise.

The lighting system of Stow's LT-12 Series Light Tower is comprised of 4 "Metal Halide" 1000 watt lamps. Each lamp has an output of 110,000 lumens yielding a total of 440,000 lumens for all four floodlights. Typical lighting coverage is between 5 to 7 acres.

Each floodlight requires a ballast for starting. Located on the control panel of the generator is a weather resistant ballast box that the contains the ballast for each floodlight. The control panel contains four ON/OFF circuit breakers for each floodlight.

CAUTION - Defective/Damaged Trailer Couplings

If the trailer coupler is deformed replace entire coupler. NEVER tow the light tower with a defective trailer coupler. There exist the possibility of the trailer separating from the towing vehicle.

Light Tower Trailer Vehicle Connection

1. Check the vehicle hitch ball, and trailer coupler for signs of wear or damage. Replace any parts that are worn or damaged before towing.

2. Use only the 2-inch ball diameter as indicated on the trailer's coupler. Use of any other ball diameter will create an extremely dangerous condition which can result in separation of the coupler and ball or ball failure.

3. Be sure the coupler is secured to the hitch ball and the lock lever is down (locked).

4. Attach safety chains as shown in Figure 7. Remember to

cross

5. After towing for about 50 miles recheck the entire towing system for tightness.

Recommended Maintenance

1. Smear ball socket and clamp face with chassis grease. Periodically oil pivot points and wear surfaces of the coupler with SAE 30 W motor oil.

2. When parking or storing the light tower, keep the coupler off the ground so dirt and other debris will not build up in the ball socket.

Tires/Wheels/Lug Nuts

Tires and wheels are a very important and critical components of the trailer. When specifying or replacing the trailer wheels it is important the wheels, tires, and axle are properly matched.

WARNING - Wheel Repair/Modification

DO NOT attempt to repair or modify a

wheel. DO NOT install an inter-tube to correct a leak through the rim. If the rim is cracked, the air pressure in the intertube may cause pieces of the rim to explode (break-off) with great force and can cause serious eye or bodily injury.

Tires Wear/Inflation

Tire inflation pressure is the most important factor in tire life. Pressure should be checked cold before operation. DO NOT bleed air from tires when they are hot. Check inflation pressure weekly during use to insure the maximum tire life and tread wear.

Table 3 (Tire Wear Troubleshooting) will help pinpoint the causes and solutions of tire wear problems.

Suspension

The leaf suspension springs and associated components (Figure 8) should be visually inspected every 6,000 miles for signs of excessive wear, elongation of bolt holes, and loosening of fasteners. Replace all damaged parts (suspension) immediately. Torqued suspension components as detailed in Table 4.

WARNING - Safety Glasses Required

General Inspection

Prior to each use, the generating set 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.

Air Cleaner

50 hours

Every ON, clean the air cleaner element.

1. Un-latch the holding clips and take out the air cleaner element.

2. Clean the inside of the body and cover using a damp cloth.

3. Blow dry with compressed air (0.69Mpa {7kgf.cm

99.4 PSI} maximum) against the side of the element along the pleats. Then blow dry against outside along the pleats, then against inside again.

4. Remove one seal each time the element is cleaned.

5. Replace the outer element after cleaning it 6 times or after one year. Replace the outer element if indicator is red even after cleaning it.

6. If seal washer is damaged or the threads of wing nut are damaged, replace.

7. Remove evacuator valve and clean it with compressed air. Reinstall.

: Check dust indicators on control panel. If light is

Fuel Addition

Add diesel fuel (the grade may vary according to season and locations). Always pour through the mesh filter.

Removing Water from the Tank

After prolonged use, water and other impurities accumulate in the bottom of the tank. Occasionally remove the drain cock and drain the contents. During cold weather, the greater the empty volume inside the tank, the easier it is for water to condense. This can be reduced by always keeping the tank as full as possible.

Air Removal

If air enters the fuel injection system of a diesel engine, starting

becomes impossible. After running out of fuel, or after disassembling the fuel system, bleed the system according to the following procedure. To restart after running out of fuel, squeeze the fuel primer bulb to pump fuel into the engine. This unit is equipped with an automatic air bleeding system.

Service Daily

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.

Cleaning the Fuel Strainer

Clean the fuel strainer if it contains dust or water. Remove dust or water in the strainer cap and wash it in diesel. Securely fasten the fuel strainer cap so that fuel will not leak. Check the fuel strainer every 200 hours of operation or once a month.

Check Oil Level

Check the crankcase oil level prior to each use, or when the fuel tank is filled. Insufficient oil may cause severe damage to the engine. Make sure the generator is level. The oil level must be between the two notches on the dipstick as shown in Figure 14.

2. Turn water filer cap slowly and remove it.

3. Prepare a container to catch the coolant, then open drain plug of the radiator or heat exchanger and drain plug of the engine, and drain the coolant.

4. After draining the coolant, close drain plugs and fill with tap water.

5. When the water level is near the mouth of the water filler, open drain plugs and start the engine, and run at low idling. Keep the engine running at low idling and flush the radiator for about 10 minutes.

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, watch carefully 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.

14. Drain the water inside reserve tank, clean the inside of the reserve tank, then fill with coolant/water mixture to between the full and low lines.

15. Stop the engine, wait for 3 minutes, add tap water until the water level reaches near the water filer port, then tighten the radiator cap.

Changing Oil

1. Make sure the oil is cool before changing.

2. Set a container directly under the drain plug of the oil pan. Loosen the drain plug slowly.

3. Check the drained oil for excessive metal particles or foreign material. Contact the distributor if there is metal particles or foreign material.

4. Using a filter wrench, turn filter cartridge to the left to remove it. If the filter cartridge is filled with a large amount of oil, wait 10 minutes or so before removing. Make sure there is no old gasket stuck on the filter holder.

5. Tighten drain plug. Clean the filter holder, fill the new filter cartridge with clean engine oil, coat the packing and thread of the new filter cartridge with engine oil, then install it to the filter holder. Tighten until the gasket surface contacts the seal surface of the filter holder, then tighten it a further 3/4 to 1 turn.

6. Add engine oil through oil filler until the oil level is between the H and L marks on the dipstick.

7. Run the engine at idling for a short time, then stop the engine. Recheck the oil level and fill as necessary.

8. After draining the water, flush the system with a flushing agent. See instructions on flushing agent label.

9. After flushing, open drain plugs and drain out all the water, then close drain plugs and add tap water so the water level is near the mouth of the water filler.

10. When the water level is near the mouth of the water filler, open drain plugs and start the engine, run at low idling and continue to flush the system until clean water comes out. Adjust the flow of the water flowing in and draining out to ensure the radiator is always full during the flushing operation.

11. When clean water comes out, stop the engine, drain all the water, then close drain plugs.

12. Remove the corrosion resistor (if equipped) and open valve.

13. Supply water until it flows over the water filler.

Replacing Fuel Filter

1. Set the container under the filter cartridge to catch fuel.

2. Using a filter wrench, turn the filter cartridge to the left to remove it.

3. Clean the filter holder, fill the new filter cartridge with fuel, coat the packing surface of the filter cartridge with engine oil, then install the cartridge to the filter holder.

4. When installing, tighten until the packing surface contacts the seal surface of the filter holder then tighten a further 2/3 of a turn. If the filter cartridge is tighten too much, the packing will be damaged and will cause fuel leakage. Fuel leakage will occur if the filter cartridge is not tightened enough. Always tighten to the correct angle.

5. Squeeze the fuel primer bulb to pump fuel back into the engine.

6. Replace Corrosion resistor cartridge (if equipped)

7. Screw in valves at the top of the corrosion resistor.

8. Using a filter wrench, turn the cartridge to the left to remove it.

9. Coat the seal surface of the new cartridge with engine oil and install it to the filter holder.

Light Tower Storage:

For storage of the generator for over 30 days, the following is required:

Fill the fuel tank completely. Treat with fuel stabilizer if necessary.

Completely drain oil from the crankcase and refill if necessary with fresh oil.

Clean the entire light tower, internal and external.

Disconnect the negative terminals of the battery and cover it, or remove it from the generator and store it separately.

If the ambient temperature is expected to drop below 0 add antifreeze to the radiator.

Cover the light tower and store in a clean, dry place away from children and non-qualified personnel.

Removal From Long Term Storage:

Apply oil to the engine valve and rocker arms, and examine the operating condition of the valves.

Change the oil in engine oil pan.

Replace all the filters.

Flush the inside of the cooling system.

10. Tighten until he packing surface contacts the seal surface of the filter holder, then tighten a further 2/3 of a turn.

11. Open valves.

Drain the water from the fuel tank and bleed the air from the fuel system.

If the engine has not been started for more than one year, contact your Perkins or Lombardini/Deutz distributor to have engine overhauled.

LT-12 SERIES LIGHT TOWER — TROUBLESHOOTING (LAMPS)

TROUBLESHOOTING GUIDE

Use the following procedure and wiring diagram on the opposite page to determine which of the four floodlights is not functioning:

Connections:

1. Make sure that floodlight #1 power cable is plugged into the J1 connector on the T-Bar assembly.

2. Make sure that floodlight #2 power cable is plugged into the J2 connector on the T-Bar assembly.

3. Make sure that floodlight #3 power cable is plugged into the J3 connector on the T-Bar assembly.

4. Make sure that floodlight #4 power cable is plugged into the J4 connector on the T-Bar assembly.

5. With the voltmeter set to the AC position, connect the negative lead of the AC voltmeter to any (neutral) white wire on the junction terminal block. This blocks connects all the neutral wires (white) in the system.

6. Connect the positive lead of the voltmeter to the output side of CB1, and observe that 120 VAC is present. Make sure circuit breaker is ON.

7. Repeat step 1-6 for CB2 thru CB4.

8. If the correct output voltages are present for CB1 thru CB4 then it can be assumed that the generator is working correctly and the correct voltage (120 VAC) are being supplied to the ballast.

Starting:

1. Start the generator and verify that there are no abnormal sounds.

2. Turn CB1 thru CB4 circuit breakers to the ON position.

3. Wait a few minutes and determine which flood light is not igniting.

4. If one of the floodlights is OFF, disconnect its power cable and plug it into a receptacle that is known to be working. DO

NOT unplug a power cable from the T-Bar while power is being supplied by the generator. Always turn the circuit breaker OFF before un-plugging a power cable.

5. If the floodlight still does not ignite after plugging it into a working receptacle (120 VAC present), then it can be assumed that the ballast for that flood light is defective. Replace ballast.

Ballast Removal:

1. Remove the power cable from the generator or welder, and make sure that no voltage is being supplied to the ballast compartment.

2. Remove the four screws securing the ballast cover, and remove cover.

3. Make sure to discharge the ballast capacitor.

3. Remove the defective ballast, taking care to guard against electrical shock when coming in contact with the ballast and capacitor. The capacitor is known to store an electrical charge, that when discharged could result in a harmful shock. Make sure to discharge capacitor.
