Note: (*) Items allow at least 3 times the listed
wattage for starting.
NOTE: Many appliances such as saws or drills draw more
current than indicated on the manufacturer's nameplate
when under severe load.
STARTING THE GENERATOR SET
Before attempting to start the generator set, ensure that
all instructions given in previous sections have been
followed completely.

Check oil and fuel levels.

Turn the fuel valve under the fuel tank on.

Turn the fuel valve on the front of the engine on.

Move the choke lever on the front of the engine on.
Note: the choke may not be required when the engine
is warm or in high ambient temperatures.

Turn idle-control On/Off switch OFF.
RECOIL START

Move engine On/Off switch to On position.

Slowly pull recoil cord until resistance is felt and then
pull firmly. Let the recoil rewind slowly to avoid
damage.

Return the choke to the original position.
ELECTRIC START

Move engine On/Off switch to On position.

Hold the On/Off switch in the Start position until the
engine starts and release. Note: If the engine does
not start after 5 seconds, stop and wait 10 seconds
and repeat this step.

Return the choke to the original position.
CAUTION: This generator is equipped with an oil
protection system. When oil levels are too low for safe

operation the engine will shut down and/or will not start
until the oil level is corrected.
OPERATING THE GENERATOR SET
Once started, allow
approximately 3 minutes. Check that the circuit breakers
and the GFCI receptacles are not tripped. Turn the idle-
control switch to the On position if this feature is to be
utilized (S5000 & S7500). Set the voltage selector switch
to the appropriate mode, either 120V or 120/240V(S5000
& S7500). See the guides below for more information on
the idle-control and voltage selector features.
IDLE CONTROL GUIDE (applicable models)
The automatic idle control system is available on some
generators. This feature allows the engine to automatically
idle down when there is no load drawn against the
generator thus saving fuel, decreasing wear and lowering
the noise level. There is an on-off switch located on the
control panel that activates or deactivates this feature. In
the on position the engine will idle down after detection of
less than 40Watts. The engine will return to the correct
running speed immediately when a load of 350Watts or
more is applied. For applications with loads less than 50W
or with near constant loads, such as home back up, it is
best to turn the idle control feature off. The feature should
be turned off before starting or stopping the generator and
turned on when there will be extended periods of inactivity
for the generator.
VOLTAGE SELECTOR GUIDE (applicable models)
The voltage selector switch allows the generator set to
produce 120 volts only or to produce 120/240 volts
simultaneously. With the switch in the 120V position only
the 120V receptacles may be used. All of the power from
the generator is available at 120 volts but the 240V output
is not available. In the 120/240V position all receptacles
are operable however only half of the generator output is
available at any one 120V receptacle. Full power may be
pulled from the generator from the 240V receptacle. The
switch should always be left in the 120V position when
240 volts are not needed. This balances the load on the
generator more effectively.
STOPPING THE GENERATOR SET
Unplug all appliances and let the engine run unloaded for
a couple of minutes. Turn the fuel valve on the front of the
engine to the Off position where installed. Turn the engine
On/Off switch to the Off position. Turn the fuel valve on
the fuel tank Off. CAUTION: Never use the choke to stop
the engine.
