⚠ The mast extends up to 25 ft (7.6 m). Make sure area above the unit is open and clear of overhead wires and obstructions.

1. For maximum light coverage, locate the unit at ground level or higher than the area being illuminated.
2. Place the unit on firm, relatively flat ground, then block the wheels to keep it from moving.
3. Pull the tongue jack locking pin, rotate the jack 90 degrees, replace the pin and raise the trailer tongue off the towing vehicle.
4. Connect a good earthen ground to the grounding stud on the frame near the trailer tongue.
5. Pull each outrigger out until the spring loaded locking pin snaps into place; rotate jacks 90 degrees pad down.
6. Pull the rear jack locking pin and rotate 90 degrees; level all four jacks until firmly in contact with the ground.
7. Before raising the mast, adjust lamps using the wing nuts on the trunnion, aim, then tighten hardware.

⚠ High Voltage. Verify area above unit is clear of overhead wires and obstructions.

⚠ Do not set up if high winds expected.

Tools: jack handles

1. Position unit at ground level or higher than area to be illuminated.
2. Place unit on firm ground less than 5° slope; block wheels.
3. Pull locking pin on tongue jack, rotate 90°, install pin. Rotate handle clockwise to raise tongue off vehicle.
4. Grounding stud on frame near tongue; follow NEC, state, local regulations.
5. Pull outrigger locking pins, pull outriggers out until spring-loaded pins snap.
6. Pull locking pin on each outrigger jack, rotate 90° so jack pad faces down.
7. Pull rear jack locking pin, rotate 90° until pin snaps.
8. Turn jack handles clockwise to level trailer.
9. Adjust all four jacks until firmly in contact with ground.
10. Adjust lamps by loosening wing nuts on trunnion; aim lamps; tighten hardware.
11. Verify lamps are connected to junction box.

⚠ Water may enter cabinet and collect in generator windings, causing damage.

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

1. If stored outside, check for water inside cabinet and generator before each use; dry if wet.
2. Inspect electrical cords; do not use if insulation cut or worn.
3. Verify winch cables in good condition and centered on each pulley; do not use kinked or unraveling cable.
4. Verify mast cable correct.
5. Verify safety pins for mast lock rod and mast lock bar present and secured with chain; check spring in mast lock bar.
6. Verify wheel lugs present and properly tightened.
7. Check coolant level daily in overflow jug; normal level between full and add.
8. Check oil level daily; do not start if below add mark; add only if below add mark; do not overfill.
9. Check fuel level.

Tools: grease gun

1. Apply a small amount of automotive grease to the internal gearing by removing the jack cover or using a 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.
4. Lubricate the caster wheel axle bolt and nut assembly with the same lightweight oil.
5. Top-wind models: apply a lightweight oil to the screw stem.

⚠ Improper use of the lower radiator hose heater could result in damage to the engine or personal injury. Do not modify the location of the lower radiator hose heater.

1. Ensure the cooling system is full of the proper mixture of water and engine coolant before each heater use.
2. The heater is designed for all-night operation; 2-5 hours of heating prior to starting is usually sufficient.
3. Ensure the unit is level to maintain proper orientation of the heater while in operation.
4. Use only an undamaged, outdoor rated, three-prong grounded 120VAC extension cord with a minimum 10A rating.
5. Before starting the engine, unplug the extension cord from the power first, then unplug the heater cordset.

⚠ Continuous use of this procedure could damage planetary gear brake of winch.

Tools: 3/8" allen head wrench

1. Remove power cables from two terminals on winch motor assembly.
2. Remove two flange head screws securing winch motor assembly to winch; retain screws.
3. Carefully remove motor assembly; ensure two pieces do not separate.
4. Insert 3/8" allen head wrench into sleeve bearing.
5. Rotate wrench counterclockwise to lower mast. If slack observed in cable, stop immediately and remove slack.
6. When mast completely down, install winch motor assembly and secure with screws.

⚠ Do not use this procedure unless absolutely necessary. Continuous use could damage the planetary gear brake of the winch. This procedure will not work if the planetary gear brake is damaged.

Tools: 3/8 inch allen head wrench

1. Remove the power cables from the two terminals on the winch motor assembly.
2. Remove the two flange head screws securing the winch motor assembly to the winch; retain the screws.
3. Carefully remove the motor assembly, making sure the two pieces do not separate.
4. Insert a 3/8 inch allen head wrench into the sleeve bearing.
5. Rotate the wrench counter-clockwise to lower the mast; if slack is observed stop immediately and remove the slack.
6. When the mast is completely down, reinstall the winch motor assembly with the retained screws.

⚠ DO NOT perform routine service unless all electrical components are shut down.

1. Verify key switch is OFF.
2. Verify circuit breakers switched OFF (O).
3. Disconnect negative (–) terminal on battery.
4. Attach "Do Not Start" sign to control panel.

1. On quick disconnect units, disconnect the power cords from the junction box at the top of the mast and replace the dust caps.
2. On hard wired units, remove the junction box cover and disconnect only the mast light wires from the connectors.
3. Remove the wing nut holding the light fixture bracket to the cross tube and attach the lights to the storage brackets.

Tools: grease gun
