SECTION 1 − SAFETY PRECAUTIONS − READ BEFORE USING Y Warning: Protect yourself and others from injury — read and follow these precautions. 1-1. Symbol Usage Means Warning! Watch Out! There are possible hazards with this procedure! The possible hazards are shown in the adjoining symbols.
WELDING can cause fire or explosion. Welding on closed containers, such as tanks, drums, or pipes, can cause them to blow up. Sparks can fly off from the welding arc. The flying sparks, hot workpiece, and hot equipment can cause fires and burns. Accidental contact of electrode to metal objects can cause sparks, explosion, overheating, or fire.
STEAM AND HOT COOLANT can burn. D If possible, check coolant level when engine is cold to avoid scalding. D Always check coolant level at overflow tank, if pres- ent on unit, instead of radiator (unless told otherwise in maintenance section or engine manual). D If the engine is warm, checking is needed, and there is no overflow tank, follow the next two statements.
READ INSTRUCTIONS. D Use only genuine MILLER/Hobart replacement parts. D Perform engine and air compressor (if applicable) maintenance and service according to this manual and the engine/air compressor (if applicable) manu- als. H.F. RADIATION can cause interference. D High-frequency (H.F.) can interfere with radio naviga- tion, safety services, computers, and communica- tions equipment.
SECTION 2 − DEFINITIONS 2-1. Symbol Definitions Circuit Breaker Positive Time SECTION 3 − SPECIFICATIONS 3-1. Description This belt or hydraulically-driven generator supplies ac power to the platform to run tools through an ac receptacle, and also operate lights, and cutting and welding equipment. All power regulation components are located in a water- tight box that is connected by cable to the generator.

4-3. Troubleshooting Trouble No generator output at platform Be sure generator control switch is turned on at platform. receptacles. Check and secure electrical connections at platform, generator, and control box. Be sure all equipment is turned off when starting unit. Reset circuit breaker CB1 (see Section 4-2).
SECTION 6 − GENERATOR POWER GUIDELINES 6-1. Selecting Equipment 6-2. How Much Power Does Equipment Require? AMPERES x VOLTS = WATTS EXAMPLE 1: If a drill uses 4.5 amperes at 115 volts, calculate its running power requirement in watts. The load applied by the drill is 520 watts. EXAMPLE 2: If three 200 watt flood lamps are used with the drill from Example 1, add the individual loads to calculate total load.
