PROBLEMS AND POSSIBLE SOLUTIONS
In Order of Occurrence
Inadequate Fuel Supply
v Undersized piping - check pressure at secondary regulator, 6 oz. Minimum.
v Condensation in line - check for flow potential, water traps and lines that run in and out
of buildings.
Improper Fuel Mixture
v Check main adjustment - see adjustment section (below).
v Check auto prime adjustment - see adjustment section (below).
Inoperative Fuel Valve
v Check function by connecting leads to generator battery. If click is heard, valve is working.
Engine Out of Tune
v Check condition AND function of spark plugs, generators running on gaseous fuel leave the
plugs very clean. It is important not to go by looks alone. If in doubt, change.
Some Multi-cylinder engines will appear to run well without load
but stumble with load, a bad plug is most often the problem.
v Check condition of air filter - replace if dirty- if pre-cleaner is saturated with oil, the fuel
system will be thrown out of balance and not operate properly.
v Oil Level - All Pow'R Gard engines have Low Oil Shutdown of varying types. To be sure,
check the oil level and, if no spark, the oil pressure switch function.
ADJUSTMENTS
Auto Prime
Pow'R Gard
®
models from 5 to 12KW can come equipped with an electric solenoid operator
'Auto Prime' device. The device is electrically connected to the starter system on the generator
and supplies an initial feed of fuel for quicker engine starting. Once started, the engine's
vacuum keeps the fuel flowing.
On generators not so equipped, the engine vacuum is used exclusively to begin and maintain
the flow of fuel.
In almost all hard starting or intermittent starting situations, the auto prime is adjusted to rich.
Please note this while making this adjustment. You would need to adjust it to be less rich.
