Starting The Engine - Hobart JET-EX 4 Operation And Maintenance Manual

(4) Make sure that no loose bars, tools, parts, etc., are in or on any part of the engine as they could
cause serious damage to the engine, generator, or personal injury to anyone standing nearby.
(5) If the unit is operated indoors, make sure that an exhaust line is properly connected to the engine
exhaust system, and discharged out of doors. Avoid short bends or reduction in line sizes in exhaust
pipes. Locate the unit so as to necessitate the shortest possible exhaust line to insure the least
amount of back-pressure on the engine. Back-pressure can cause engine damage and loss of power.
(6) Check the electrical system to make sure the connections are secure and properly connected.
Check the battery electrolyte level.
