7. 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 render-
ing 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
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 circuit
be fused for 15 amps, then both the battery charger and
the block heater can be connected to the same circuit.
These units have a duplex receptacle mounted on the
rear engine support bracket. The wires for this recep-
tacle 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 can be plugged into
the extra receptacle on the duplex.
** 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.
MOUNTING THE AUTOMATIC
TRANSFER SWITCH (A.T.S.)
*************
***** WARNING *****
*************
EQUIPMENT DAMAGE- Protect the switch from construc-
tion grit and metal chips to prevent a malfunction or
shortened life of the switch. Contactors returned for
warranty consideration wilth foreign material inside of
them will not be warranted.
The Automatic Transfer Switch connects the load
(lights, furnace, outlets, etc.) to the normal power line
during standby. When normal power fails, the A.T.S.
starts the engine generator set, disconnects the power
line and then connects the load to the standby generator
set. When normal power is restored, the automatic
switch retransfers the electrical load to the normal
service and stops the engine. The A.T.S. panel should
be mounted as close to the distribution panel as
possible.
*****NOTE*****
EQUIPMENT DAMAGE- The standard NON-UL Winco
ATS does not protect against undervoltage. If you are in
an area that is suspectible to brown outs (low voltage)
you may want to consider adding an undervoltage sensor
to standard ATS panel.
