STOPPING THE GENSET
Turn off the air conditioner and other large ap-
pliances and let the genset run for two minutes to
cool down. This reduces backfiring and run-on.
Then press the switch to STOP to stop the genset.
RESTARTING THE GENSET
See Troubleshooting (Page 4-1) if the genset shuts
down abnormally.
LOADING THE GENSET
The genset can power AC motors, air conditioners,
AC/DC converters and other appliances. How much
appliance load* can be powered depends upon the
genset power rating. The genset will shut down or its
circuit breakers will trip if the sum of the loads ex-
ceeds genset power.
To avoid overloading the genset and causing shut-
downs, compare the sum of the loads of the ap-
pliances that are likely to be used at the same time to
the power rating of the genset. Use Table 2-1 or the
ratings on the appliances themselves (if so marked)
to obtain the individual appliance loads. It may be
necessary to run fewer appliances at the same
time—the sum of the loads must not be greater
than genset rating.
Note that the genset may shut down due to over-
load—even though the sum of the loads is less than
genset rating—when a large motor or air conditioner
is started last or cycles off and then on again. The
reason for this is that a motor’s startup load is much
larger than its running load. It may be necessary to
run fewer appliances when large motors and air
conditioners are cycling on and off.

Note also that air density decreases as altitude in-
creases, causing genset engine power to de-
crease.** Power decreases approximately 3.5 per-
cent of rated power each 1000 feet (305 m) of in-
crease in elevation. See Table 2-2 for typical cal-
culations. It may be necessary to run fewer ap-
pliances at higher altitudes.

* This table does not take into account the effect cir-
cuit breakers may have in limiting maximum power.
* Appliance load and genset power are measured in terms of watts (W) or kilowatts (kW), where 1 kilowatt (kW) = 1000 watts (W).
** Power decreases even though the altitude adjust knob is set correctly (Page 2-4).
