Owner's Manual

Our PSS40 is equipped with a 6-cyl GM 4.3L  liquid cooled engine that can run off of NG or LP, and can start up to a 12HP Code G motor. This is a 2-wire unit and comes with a mainline circuit breaker as standard equipment. This generator is available in single phase 120/240V, and three phase 120/208V, 120/240V, 277/480V.

The 4 cylinder, overhead valve GM 3.0L engine meets EPA/Carb Emission Regulations for LSI Engines. All engine functions are controlled by an engine mounted ECM. The engine features include an electronic ignition, engine blockheater and vapor fuel system. A critical grade muffler is installed to reduce engine noise levels. Battery rack, cables, and battery tender (charger) are factory installed. A BCI Group 24 650 CCA battery must be purchased separately. Engine cooling is provided by a unit mount radiator. The engine is equipped with a belt driven pusher type fan.

The generator is a single bearing rotating field generator mounted to the engine flywheel via dual flex drive discs. Three phase generators have 12 lead broad range reconnectable stators; single phase generators are 4 lead. An external voltage regulator maintains proper voltage output, accurate to +/- 1%. The engine generator combination has the ability to start and operate motors up to 8 hp Code G. Mainline circuit breaker included for generator protection.
