Briggs & Stratton Power Products Standby Generator
Installation, Start-Up and Owner’s Manual
BEFORE INITIAL START-UP
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 owner’s manual.
Oil Considerations
Your Standby Generator is equipped with an engine that
has been pre-run at the factory and does not require the
traditional “break-in” procedure.
The generator is filled with synthetic oil (API SJ/CF 5W-
30W).This allows for generator operation in the widest
range of temperature and climate conditions.
NOTE:The use of synthetic oil DOES NOT alter the
required oil change intervals described in the engine
owner’s manual.
Battery Connection
The Standby Generator is supplied with a 12Volt DC
33 Amp-Hour battery. It is a sealed, lead-acid rechargeable
battery. It is installed in the unit and the battery cables are
connected at the factory.The generator’s 15 Amp fuse has
been removed to prevent the battery from discharging and
the unit from starting during shipping.
If it is necessary to service the battery, proceed as follows:
1. Set generator's “AUTO/OFF/MANUAL” switch to
OFF.
2. Pull service disconnect from disconnect box.
3. Remove 15 Amp fuse from control panel.
4. Service or replace battery as required.
5. Connect red battery cable to positive battery terminal
(indicated by POSITIVE, POS, or (+).
6. Connect black battery cable to negative battery
terminal (indicated by NEGATIVE, NEG, or (-).
7. Ensure hardware on both positive and negative battery
terminals is secure.
8. Reinstall 15 Amp fuse in control panel.
9. Reinstall service disconnect in disconnect box.
10. Set generator's “AUTO/OFF/MANUAL” switch to
AUTO.
11. Reset exercise timer following instructions “Setting
Exercise Timer” on page 19.
NOTE:With the battery installed and utility power
available to the Transfer Switch, the battery receives a
trickle charge whenever the engine is not running.The
trickle charge only prevents self-discharge and cannot be
used to recharge a battery that is completely discharged.
Fuel Supply System
Ensure that all fuel pipe connections are tight, secure and
without leaks.
Ensure that all gas line shutoff valves are OPEN and that
adequate fuel pressure is available whenever automatic
operation is desired.
FUEL SYSTEM SELECTION
The engine of your Standby Generator is factory calibrated
to run on natural gas (NG). It may also be operated on
liquid propane (LP).
To configure the fuel system for LP use:
1. LP fuel inlet pressure must be between 11 and
14 inches water column.
2. Set AUTO/OFF/MANUAL switch to OFF.
3. Pull service disconnect from disconnect box.
4. Remove 15 Amp fuse.
5. Change main jet in fuel mixer following instruction
sheet provided in LP conversion kit.
NOTE:You will need a specialty tool, as described on
page 9, to change the main jet.
6. Reinstall 15 Amp fuse.
7. Reinstall service disconnect in disconnect box.
• DO NOT install the 15 Amp fuse until all plumbing and wiring
has been completed and inspected.
Installing the 15A fuse could cause the engine to start.
CAUTION
CAUTION
• Refer to engine manual for oil fill information.
• Damage to equipment resulting from failure to follow this
instruction will void warranty.
Any attempt to crank or start the engine before it has
been properly serviced with the recommended oil will
result in equipment failure.
