Section 3 - Operation LIGHT TOWER SET UP 1. For maximum light coverage, locate the unit at ground level or in a spot higher than the area being illuminated by the lamps. WARNING The mast extends up to 30 ft (9.14 m). Make sure the area above the unit is open and clear of overhead wires and obstructions.
Operation 6. Pull the locking pin on the rear jack (F) and rotate the jack 90°. Replace the locking pin. Turn the jack handle clockwise to start leveling the trailer. Adjust all four jacks by turning their handles clockwise (G) until they are firmly in contact with the ground and the trailer is as level as possible.
Operation RAISING THE MAST 1. Set up and level the unit. Refer to “Light Tower Set Up” on page WARNING The unit must be leveled with the outriggers extended before raising the mast. The DETAIL A DETAIL C DETAIL E outriggers must remain extended while the mast is up.
Operation WARNING Never raise or lower the mast while the unit is operating. Never remove the safety pin or release the mast lock while the mast is up. Releasing the lock will cause the mast to fall. RAISING THE MAST WITH ELECTRIC WINCH OPTION 1.
Operation CAUTION Do not extend the mast beyond the colored mark on the middle mast tube (G). A limit switch on the main mast section will disconnect power to the upper electric winch to prevent overextending the mast. 7. Rotate the mast by loosening the mast rotation knob at the bottom of the mast (H). Turn the mast until the lights face in the desired direction and then tighten the mast rotation knob to secure the mast in position.
Operation 3. Once the engine is running, allow it to reach normal operating temperature before switching on any loads. LIGHT OPERATION WARNING NEVER operate the lights without the protective lens cover, or with a lens cover that is cracked or damaged. The bulbs in the light fixtures produce high temperatures and operate under pressure.
Operation VOLTAGE REGULATOR OPTION The electronic voltage regulator controls the output of the generator by regulating the current into the exciter field. The regulator has three screwdriver adjustable potentiometers that may be adjusted for voltage, stability and voltage roll-off (U/F). The voltage regulator on your unit is adjusted before shipment from the factory. Contact Generac Mobile Products for additional information before attempting to adjust the voltage regulator.
Operation AUTOMATIC SHUTDOWN This unit is equipped with a low oil pressure and high coolant temperature automatic shutdown system. This system will automatically shut off the fuel supply to stop the engine if oil pressure drops too low or the engine exceeds normal operating temperature.
Operation 3. Press and hold the upper winch control switch downward to collapse the mast to its lowest position. Ensure the electrical cord does not get caught in, or pinched by, the mast while it is being lowered. Note: Some electric winch models are equipped with an anti-backlash safety limit switch. This switch will disconnect power to the winch if excess cable slack is detected, preventing accidental lowering of the mast.
Operation REMOVING THE LIGHTS FOR TRANSPORTATION 1. On units equipped with quick disconnect fittings for the lights, disconnect the power cords from the junction box at the top of the mast. Replace the dust caps on the junction box. On hard wired units, remove the junction box cover, located on the top of the mast, and disconnect ONLY the mast light wires from the connectors.
Operation 10. Check the wheel lugs. Tighten or replace any lugs that are loose or missing. If a tire has been removed for axle service or replaced, tighten the lugs, in the order shown, to the following specifications: a. Start all lug nuts by hand. b.
Section 4 - Maintenance Normal maintenance service and replacement of parts are the responsibility of the owner/operator and, as such, are not considered defects in materials or workmanship within the terms of the warranty. It is strongly recommended that the equipment be periodically checked by a Generac Mobile Products Authorized Dealer. DAILY WALK AROUND INSPECTION Look for conditions that could hinder performance or safety, such as (but not limited to) oil/coolant/fuel leakage, blocked vents, loose/missing hardware, and electrical connections.
Maintenance overflow jug. • Check the oil level daily.

Maintenance dusty conditions, clean the fuel tank as often as necessary. BASIC MAINTENANCE SCHEDULE - KUBOTA ENGINE Refer to the original equipment manufacturer’s operating manual for a complete list of maintenance requirements. Failure to comply with the procedures as described in the engine operator’s manual will nullify the warranty, decrease performance and cause equipment damage or premature equipment failure.
Maintenance Operation Take Line/Load In: 1. The cable must be securely fastened to the object being lifted and to the winch drum. 2. Always be sure that the cable and cable attachments are not damaged and are strong enough for the load. Ensure there is an adequate safety factor of at least three times the maximum load for all components used.
Maintenance • Periodically clean and grease the brake assembly. This will ensure proper performance and extend the life of the winch. If winch seems to labor or get excessively hot during the lowering of loads, the brake will need to be serviced or replaced. •...
Maintenance Top-Wind Models • Apply a lightweight oil to the screw stem. Grease Grease Grease 00243 Figure 19 - Applying Oil to Jacks TRAILER WHEEL BEARINGS The trailer axles are equipped with a grease zerk fitting to allow lubrication of the wheel bearings without the need to disassemble the axle hub.
