Operation
Important Owner’s Considerations
Engine Oil
NOTICE
Any attempt to crank or start the engine before it has been
properly serviced with the recommended coolant or oil will
result in equipment failure.
Refer to Maintenance in the Operator’s Manual and
engine manual for coolant and 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 pre-run and filled
with non-synthetic oil (API SL 10W-30W). This allows for
system operation in a wide range of temperature and climate
conditions. Before starting the engine, check oil level and
ensure that engine is serviced as described in the engine
operator’s manual.
NOTE: The use of multi-grade oil does not alter the required
oil change intervals described in the engine operator’s
manual.
Coolant System
This engine is shipped from the factory filled with a
50-50 mix of automotive (Dex-Cool™ orange) anti-freeze
and water. This will provide optimum year round protection
against freezing, boiling and corrosion. The coolant system
incorporates a water heater that operates when ambient
temperature is below 80ºF AND utility power is present at
the transfer switch. Before starting the engine, check coolant
level as described in the engine operator’s manual.
Battery
The installer must supply a sealed, rechargeable 12 Volt DC,
650 Cold Cranking Amps (CCA) 55 amp hour starting battery.
The battery may not be at full charge when installed. If
battery voltage is below 12 Volts, charge the battery. See
Battery in the Maintenance section for details.
15 Amp Fuse
The generator’s 15 Amp fuse is critical to correct system
operation. Your installer will ensure the fuse is properly
installed upon completion of the installation.
Automatic Operation
To select automatic operation, do the following:
1. Confirm 15 Amp fuse is installed in control panel.
2. Set the main distribution panel circuit breaker that
sends utility voltage to the transfer switch to ON.
3. Set the generator’s main circuit breaker to its ON
position.
4. Set the control panel System switch to AUTO.
CAUTION
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 if
performing maintenance on the system.
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 main distribution panel circuit breaker
sending power to automatic transfer switch.
The engine will crank and start when utility voltage is lost
and the sensor has timed out. Let the system go through its
entire automatic operation sequence.
2. With generator output supplying its loads, turn ON main
distribution panel circuit breaker that supplies utility
power to Automatic Transfer Switch.
3. The automatic transfer switch will transfer loads back
to 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 and will
supply power to the transfer switch when utility power is
lost.
