Operation LTC 4L 3.10 Starting See Graphic: wc_gr001068, wc_gr001426, wc_gr002758 3.10.1 Check the engine oil, fuel and coolant levels. Note: If the fuel tank was drained or run dry it may be necessary to bleed the fuel lines. Refer to the Engine Operator’s Manual. 3.10.2 Check the condition of the electrical cable on the mast. Do not start the generator if the insulation on the cable is cut or worn through. 3.10.3 Check that the circuit breakers (a, b, c) are in their OFF position. NOTICE: Starting the engine under load will damage the machine. 3.10.4 On machines equipped with the Lombardini engine, turn the key (q) one click to the right. The glow plug indicator (n) will illuminate until the engine is properly preheated. This is an automatic timer based on the engine temperature. Crank the engine immediately after the glow plug light goes off. 3.10.5 Turn the key (q) to START and hold until the engine starts. Release the key after engine starts. NOTICE: Do not crank the engine longer than 10 seconds. This could cause starter motor to overheat. Return switch to OFF and wait 15-30 seconds for the starter motor to cool down before attempting to preheat and restart. Note: If the oil pressure is not obtained within 30 seconds after the key is turned to RUN, the automatic shutdown system will shut off the fuel supply. You must return the key to the OFF position to restart the 30 second timer before attempting to restart the engine. 3.10.6 Allow the engine to warm up before operating the floodlights. 3.11 Automatic Shutdown This unit is equipped with a low oil, high temperature auto-shutdown system. This system will automatically shut off the fuel supply to the engine if the oil pressure drops too low or the engine exceeds normal operating temperatures. Return the key switch to “OFF” to reset the unit after an engine shutdown. 36
LTC 4L Operation 3.12 Operating Lights See Graphic: wc_gr001068, wc_gr001426, wc_gr002758 3.13 Stopping Turn on the circuit breaker (a) first, then turn each circuit breaker (b) to “ON”, one at a time. Metal halide floodlights require a warm-up time of 5–15 minutes before they reach full output. If the floodlights are shut down, a 10-minute cool-down period is required before turning them back on. High pressure sodium floodlights require 1–2 minutes to start and 2–5 minutes of cooldown time to restart. See Graphic: wc_gr001068, wc_gr001426, wc_gr002758 3.13.1 Turn the circuit breakers (a, b, c) off and remove any other loads from the generator. NOTICE: Never shut down the engine without turning off the lights. Damage to the generator will occur. 3.13.2 Turn the key (q) to OFF. 3.14 Receptacles—50 Hz See Graphic: wc_gr002933 and wc_gr003766 The control panel is equipped with a convenience receptacle for running accessories and tools from the generator. Power to this receptacle is available any time the engine is running and the circuit breaker is “ON”. NOTICE: Do not draw more than 2000 Watts from the receptacle with all of the lights on. A 20A circuit breaker (c) protects the 250V (0009485), 115V (0009379) receptacle (d). 37
