Important Owner's Considerations

Engine Oil
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.
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.
Battery
The residential generator is supplied with a valve-regulated
rechargeable 1 Volt battery. The battery cables are
connected at the factory.
WARNING
Battery posts, terminals and related
accessories contain lead and lead compounds
- chemicals known to the State of California
to cause cancer and reproductive harm. Wash
hands after handling.
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 Sequence

The generator's control panel houses a logic control circuit
board. This control board constantly monitors utility power
source voltage. Should that voltage drop below a preset
level, control board action will signal the engine to crank
and start.
When utility source voltage is restored above a preset
voltage level, the engine is signaled to shut down.
The actual system operation is not adjustable and is
sequenced by sensors and timers on the control board,
as follows:
utility Voltage Dropout Sensor
• This sensor monitors utility source voltage.
• If utility source voltage drops below about 70 percent
of the nominal supply voltage, the sensor energizes
a 10 second timer. The timer is used to 'sense'
brown-outs.
• Once the timer has expired, the engine will crank
and start.
