Isuzu 4LE1NYGV-03 / 4LE1NYGV-03E Engine

⚠ High Voltage. Verify area above unit is clear of overhead wires and obstructions. Contact with high-voltage power lines will result in death or serious injury.

⚠ Do not set up the unit if high winds are expected. High winds can cause the unit to tip or fall, causing severe injury or machine damage.

⚠ Tipping hazard. Extend the outriggers and level the unit before raising the mast. Keep the outriggers extended while the mast is up. Failure to do so could cause the unit to tip and fall and could result in death or serious injury.

1. For maximum light coverage, position the unit at ground level or higher than the area being illuminated.
2. Place unit on firm ground that is relatively flat (less than 5° slope) and block the wheels.
3. Pull the tongue jack locking pin, rotate jack 90° until the spring loaded pin snaps into place, then raise the trailer tongue off the towing vehicle.
4. A grounding stud is located on the trailer frame near the trailer tongue; follow NEC, state and local regulations.
5. Pull the outrigger locking pins, pull each outrigger out until the pin snaps into place.
6. Pull the locking pin on each outrigger jack and rotate each jack 180° so the jack pad faces down; verify the pin snaps into place.
7. Pull the locking pin on the rear jack, rotate it 180° until the pin snaps into place, then turn the jack handle clockwise to begin leveling.
8. Rotate each jack handle clockwise until all four jacks are firmly in contact with the ground.
9. Loosen the wing nuts on the trunnion to aim lamps up, down, left or right; tighten hardware completely.
10. Verify the lamps are connected to the junction box.

⚠ Equipment Damage. Water may enter the cabinet and collect in the generator windings or other electrical parts, causing damage.

⚠ Only use mild soap and water to clean the lens covers. Other chemicals may damage the lens covers.

Tools: Soft clean rags, Low-pressure compressed air (less than 40 PSI [276 kPa])

1. Clean the Light Tower after each use to remove dust, grease, mud, or spilled fuel or oil.
2. Use soft, clean rags to wipe the cabinet exterior and control panel.
3. Low-pressure compressed air (less than 40 PSI [276 kPa]) can be used to remove dust and debris from the cabinet interior.
4. Do not wash the unit with a high pressure hose or power washer.
5. Do not wash the engine block or fuel tank with a power washer or steam cleaner.

⚠ Equipment Damage. Failure to perform a daily inspection could result in damage to the unit.

1. Perform a walk-around inspection of the unit every day before starting the unit.
2. Look for oil, coolant and fuel leakage.
3. Look for blocked vents.
4. Look for loose or missing hardware.
5. Look for loose or broken electrical connections.
6. Inspect the fan belt for cracks, fraying, or stretching and verify it is properly seated in the pulley grooves.

Tools: Automotive grease, Lightweight oil, Needle nose applicator or standard grease gun

1. For side-wind models, apply a small amount of automotive grease to the internal gearing by removing the jack cover, or use a needle nose applicator or standard grease gun on the lubrication point.
2. Rotate the jack handle to distribute the grease evenly.
3. Apply a lightweight oil to the handle unit at both sides of the tube for side-wind models.
4. If equipped, lubricate the axle bolt and nut assembly of the caster wheel with the same lightweight oil.
5. For top-wind models, apply a lightweight oil to the screw stem.

⚠ Risk of burns. Allow engine to cool before draining oil or coolant. Failure to do so could result in death or serious injury.

⚠ Electrocution. Potentially lethal voltages are generated by this equipment. Render the equipment safe before attempting repairs or maintenance.

1. Verify the key switch is in the OFF position.
2. Verify the circuit breakers are switched OFF (O).
3. Disconnect the negative (–) terminal on the battery.
4. Activate (push in) the emergency stop switch.
5. Attach a 'Do Not Start' sign to the control panel.

Tools: Standard grease gun, Clean cloth

1. Remove the small rubber plug on the grease cap.
2. Attach a standard grease gun fitting to the grease zerk fitting.
3. Pump grease into the fitting until new grease is visible around the nozzle of the grease gun.
4. Wipe any excess grease from the hub with a clean cloth and replace the rubber plug.

Tools: Grease, Oil

1. Apply a thin film of grease to the gear teeth and oil the shaft bushings as needed.
2. Keep the ratchet pawl pivot point lubricated with a thin oil.
3. Do not get oil or grease on the friction discs.

⚠ Crushing hazard. Verify unit is properly secured and on level ground. An unsecured unit can suddenly roll or move, causing death or serious injury.

1. Verify the equipment being used to lift the unit is in good condition and has sufficient capacity.
2. Close and lock all hoods and doors and stow the lights as shown.
3. Verify the cradle locking pin is in place.
4. When lifting the light tower and trailer, attach any slings, chains or hooks directly to the central lifting eye.
5. Always remain aware of people and objects around the unit while preparing, maneuvering, and lifting the unit.
6. Use the upper or lower forklift pockets with care, approaching as perpendicular as possible to avoid damage.

⚠ Burn hazard. Never operate lights with a damaged or missing lens cover. Lamps are hot and pressurized while in use. Unprotected lamps can shatter, causing severe injury.

⚠ Burn hazard. Lamps become extremely hot while in use. Allow 10-15 minutes for cooling before handling or lowering mast.

1. Verify the unit is on and running smoothly.
2. Switch the main circuit breaker ON (I).
3. Switch the individual circuit breakers for the lights ON (I), one at a time.
4. The ballast indicator lights will turn on and continue to get brighter as the lights warm up, then remain on.

⚠ Burn hazard. Lamps become extremely hot while in use. Allow 10-15 minutes for cooling before handling or lowering mast. Touching a hot lens or fixture can cause severe burns.

⚠ Personal Injury. Stop immediately if the mast hangs up or the winch cable develops slack. Excess slack could cause the mast to collapse, resulting in personal injury or equipment damage.

1. Shut down the lights and engine.
2. To rotate the mast, loosen the mast rotation knob, rotate until the white arrows are aligned and metal stop tabs are touching, then tighten the knob.
3. Turn the upper mast winch handle counterclockwise to collapse the mast to its lowest position; verify the coiled electrical cord does not get caught or pinched.
4. Pull the safety pin on the mast lock and pull the lock bar free; turn the lower mast winch handle counterclockwise until the mast rests in the transport cradle.
5. Insert the mast cradle locking pin and secure it with the safety pin.

⚠ Improper use of the lower radiator hose heater could result in serious personal injury.

Tools: Outdoors rated, three-prong grounded 120VAC extension cord, minimum 10A

1. Verify that the cooling system is full of a proper mixture of water and engine coolant before each heater use.
2. Heater is designed for all-night operation; 2-5 hours of heating just prior to starting is usually sufficient.
3. Unit must be parked in a level position to maintain proper orientation of the heater while the heater is in operation.
4. Use only an undamaged extension cord, outdoors rated, three-prong grounded 120VAC cord with a minimum amperage rating of 10A, connected to a properly grounded 120VAC GFCI outlet.
5. Before starting the engine, unplug the extension cord from power first, then unplug the heater cordset from the extension cord.

1. Activate the emergency stop switch by pushing the red button in until it locks down.
2. This trips the main circuit breaker, opening the contact and disconnecting the load to the connection lugs, and opens the fuel circuit, shutting down the engine.
3. The switch remains closed until it is pulled out.
