LT-12 SERIES LIGHT TOWER — INSPECTION Before Starting 1. Read all safety instructions at the beginning of manual. 2. Clean the light tower, removing dirt and dust, particularly the engine cooling air inlet and air cleaner. Figure 11. Dipstick 3. Check the air filter for dirt and dust. If air filter is dirty, replace air filter with a new one as required. 4. Check all fastening nuts and bolts for tightness. WARNING - Ventillation Requirements 5.
LT-12 SERIES LIGHT TOWER — INSPECTION Battery Check Fuel Check CAUTION - Diesel Fuel Safety Diesel fuel and its vapors are dangerous to your health and the surrounding environment. Avoid skin contact and/or inhaling fumes. DO NOT smoke while refueling. DO NOT attempt to refuel the light tower if the engine is hot! or running. WARNING - Battery Safety The operator MUST wear the appropriate protective equipment and clothing while handling the battery.
LT-12 SERIES LIGHT TOWER — INSPECTION Coolant (Ethylane Glycol [Green] / Water — 50/50 mix) Use only drinkable tap water. If hard water or water with many impurities is used, the inside of the engine and radiator may become coated with deposits and cooling efficiency will be reduced. An anticorrosion additive added to the water will help prevent deposits and corrosion in the cooling system. See the engine manual for further details.
LT-12 SERIES LIGHT TOWER — INSPECTION WARNING - Respiratory Hazard The engine's exhaust contains harmful emissions. ALWAYS ventilate the exhaust when operating inside tunnels, excavations or buildings. Direct exhaust away from nearby personnel. Before starting the engine perform the following: 1. Be sure to disconnect the electrical load and switch the main circuit breaker and all lamp (4) circuit breakers to the OFF position prior to starting the engine. 6. Bottom tower mast is locked in place. 7.
LT-12 SERIES LIGHT TOWER — STARTUP PROCEDURES Starting the Engine Starting the Engine (Lombardini/Deutz Engines) The Night-Hawk LT-12 Series Light Tower is available with two types of engines (Perkins or Lombardini/Deutz). The engine starting procedure contained within this manual will address both engines.. 1. Open the access panel door on the right-side of the light tower (opposite the fuel tank). Set the door latch in place to hold the door open (up) Starting the Engine (Perkins Engines) 1.
LT-12 SERIES LIGHT TOWER — SHUTDOWN PROCEDURES Normal Shut-down Emergency Shut-down 1. If a load is attached to the generating set of the light tower, remove the load. 1. Turn the ignition key to the OFF position. 2. Set CB-1 thru CB-4 on the control panel to the OFF position. 3. Place the MAIN circuit breaker (Figure 5, Item 4) on the control panel to the OFF position. 4. Wait a few seconds and observe that flood all floodlights are OFF. 5. Let the engine idle for a few minutes with no load. 6.
LT-12 SERIES LIGHT TOWER — MAST OPERATION DANGER - Overhead Obstruction Danger ALWAYS make sure the area above Light tower is open and clear of overhead power lines and other obstructions. The mast extends in excess of 30 ft. (9 meters). Contact with overhead powerlines or other obstructions could result in equipment damage, Serious Injury or Death! DO NOT stand behind the trailer while the mast is being raised or lowered. Serious Injury could result if the mast falls down.
LT-12 SERIES LIGHT TOWER — OPERATION Turning On the Flood Lights Applying an External Load The Main Circuit Breaker (25 amps), and 4 floodlight circuit breakers (10 amps each) are located on the upper control panel (Figure 20). Please note that there is one 10 amp circuit breaker for each floodlight. The Night-Hawk LT-12 Series Light Tower is available with two auxiliary output receptacles (Figure 18).
