Operation

Important Owner's Considerations
Engine Oil
This engine is shipped from the factory filled with the
recommended oil. Before starting the engine, check oil level
and ensure that engine is serviced as described in the engine
operator's manual. See Engine Oil in Maintenance.
NOTICE
Any attempt to crank or start the engine before it has been
properly serviced with the recommended oil will result in
equipment failure.
• Refer to Maintenance and engine manual for oil fill
information.
• Damage to equipment resulting from failure to follow this
instruction will void engine and generator warranty.
Battery
The home generator is supplied with a sealed, lead-acid,
rechargeable, 12 Volt DC 55 Amp-Hour, valve regulated
battery. It is installed in the unit and the battery cables are
connected at the factory.
With the battery installed, all wiring to transfer switch and
home generator completed, utility power supplied to the
Automatic Transfer Switch, and the unit in AUTO mode,
the battery receives a trickle charge while the engine is not
running. The trickle charge cannot be used to recharge a
battery that is completely discharged.
15 Amp Fuse
The generator's 15 Amp fuse was removed at the factory to
prevent the unit from starting during shipping. Your installer
will ensure the fuse is properly installed upon completion of
the installation.

Automatic Operation

To select automatic operation, do the following:
1. Set the service disconnect or main distribution panel
circuit breaker that sends utility voltage to the transfer
switch to ON.
2. Set the generator's main circuit breaker to its ON
position.
3. Set the system switch to AUTO.
With the system switch set to AUTO, the engine
may crank and start at any time without warning.
Such automatic starting normally occurs when
utility source voltage drops below a preset level
or during the normal exercise cycle.
• To prevent possible injury that may be caused by such
sudden starts, always set the system switch to OFF.
• Remove the 15 Amp fuse before working on or around
the generator or transfer switch.
Checking Automatic Operation
To check the system for proper automatic operation, proceed
as follows:
1. Turn OFF the service disconnect or main distribution
panel circuit breaker sending power to the automatic
transfer switch.
The engine will crank and start when the utility voltage drops
out and the sensor has timed out. Let the system go through
its entire automatic operation sequence.
2. With the generator output supplying its loads, turn ON
the service disconnect or main distribution panel circuit
breaker that supplies utility power to the Automatic
Transfer Switch.
3. The automatic transfer switch will transfer loads back to
the utility power after 5 minute minimum run time and
utility is restored.
4. The generator will run for an additional one minute for
engine cool down, then shut down.
NOTE: If utility is restored and generator does not shut down
after 10 minutes, set system switch to OFF and contact your
installer or local service center.
This completes the test procedures for automatic operation.
The home generator will now start automatically when utility
power is lost and will supply power to the transfer switch.
