If the pressure is correct, remove the meter and

reinstall the pipe plug. Next remove the 1/8 inch NPT plug
on the carburetor side of the regulator and install the
pressure meter. Move the generator switch to the run
position. As soon as the solenoid opens the pressure
should rise 2.5 to 3 oz. just as the engine starts to crank.
If it is within this range replace the cap on the column. If
not, adjust the screw down to increase and up to
decrease and retest.

You are now ready to make the final fuel mixture

adjustment. Refer to adjustment section in this manual.

LUBRICATION

Before starting the engine, check the oil and, refill if

required, the crankcase with the proper weight/grade of
oil, as recommended by the engine manufacturer’s
maintenance instructions. The necessity of using the
correct oil, and keeping the crankcase full cannot be over
emphasized.

INSTALLING THE BATTERY

**** CAUTION ****

In the following battery installation procedure, check to
be sure the selector switch remains in the “stop” position.
This should be your last step before initial start-up.

A customer supplied twelve-volt battery is required to

complete the installation. Installation of the highest CCA
rated battery, within the correct BCI group, will increase
cold weather starting performance. Use only Mainte-
nance Free batteries, this will reduce the need to refill the
battery with water. Gel batteries should not be used with
the battery tender installed in the generator enclosure.

*****CAUTION*****

EQUIPMENT DAMAGE - Always connect the positive
cable first and the negative cable last, when disconnect-
ing it is negative cable first and positive last. Failure to
connect and disconnect in the proper sequence can
cause equipment damage.

Observe polarities: connect the positive (+) battery

terminal to the (+) cable from the control panel; the
negative (-) battery terminal is connected to the negative
cable (ground) from the engine generator assembly.

All connections must be clean and tight. Check the

electrolyte (fluid) in the battery monthly to be sure it is
above the plates. Never allow the battery to remain in a
discharged condition.

*****CAUTION*****

EQUIPMENT DAMAGE - NEVER jump start these units.
Doing so will destroy the engine control module rendering
the unit non-operational. Remove and fully recharge the
battery before attempting to start.

CONNECTING THE BATTERY CHARGER &
BLOCKHEATER

The battery tender and frost plug heater require a

GFCI circuit breaker protected AC circuit from your
distribution panel be run out to the engine generator set.
These AC wires can be run in the same conduit as the
other AC leads from the generator. It is suggested that
this GFCI circuit be fused for 15 amps, as both the battery
charger and the block heater are connected to this circuit.
These units have a duplex receptacle mounted on the
control panel just below the operational switches. The
wires for this receptacle have been routed up into the
generator connection box for your convenience. You will
make your connection from your 120 volt power feed in
the connection box.

A two-stage battery tender is provided on all these

generators. This battery tender charges at a rate of 750
mA until the battery is fully charged and then automati-
cally switches to a 13.2 VDC float charger. The charger
has an indicator light on it, red indicates it is charging,
and green indicates it is in the storage mode (float
charge). The battery tender was shipped already plugged
into the duplex receptacle. All DC connections from the
battery tender to the battery have already been made.

A frost plug heater and thermostat are installed as

standard equipment. The thermostat used on these units
has a operating range of on at 22 degrees and off at 32
degrees air temperature. The heater is plugged into the
other receptacle on the duplex which has a thermostat in
series with the power feed. Do not reverse the recep-
tacles that the devices are plugged into or you will
end up with the battery charge on the thermostat
controlled circuit.

** NOTICE **

The battery tender is not intended to recharge a battery
which has become completely discharged. It is de-
signed to produce enough current to recharge a slightly
low battery, maintaining it fully charged.
