9. Allow the unit to cool.
10. Set the generator’s main circuit breaker to its
OFF (or OPEN) position.
11. Set the generator's AUTO/OFF/MANUAL switch
to OFF. Remove the 7.5A and 15A fuses from the
generator control panel. Disconnect the battery
cables as outlined in “General Hazards” (page
2).
12. Drain the oil and remove the oil filter. Replace
the oil filter according to Section 3.4, “Changing
the Oil Filter”. Replace the oil with synthetic oil
as recommended in Section 3.3, “Changing the
Engine Oil”.
13. Reconnect the battery cables as outlined in
“General Hazards” (page 2) and insert the 7.5A
and 15A fuses into the generator control panel.
The generator is now ready for service.
3.2 USING THE AUTO/OFF/MANUAL
SWITCH (FIGURE 3.1)
3.2.1 “AUTO” POSITION
Selecting this switch position activates fully auto-
matic system operation. It also permits starting and
exercising the engine every seven days with the set-
ting of the exercise timer (see “Setting the Exercise
Timer” section). This position also is used for remote
starting, when it is set up.
3.2.2 “OFF” POSITION
This switch position shuts down the engine. This
position also prevents automatic operation.
3.2.3 “MANUAL” POSITION
Set the switch to MANUAL to crank and start the
engine. Transfer to standby power will not occur
unless there is a utility failure.

With the switch set to AUTO, the engine may
crank and start at any time without warning.
Such automatic starting normally occurs when
utility power source voltage drops below a pre-
set level or during the normal exercise cycle. To
prevent possible injury that might be caused by
such sudden starts, always set the switch to OFF
and remove both fuses before working on or
around the generator or transfer switch. Then,
place a “Do Not Operate” tag on the generator
panel and on the transfer switch.
3.3 AUTOMATIC TRANSFER
OPERATION
To select automatic operation, do the following:
1. Make sure the transfer switch main contacts are
set to their UTILITY position, i.e., loads con-
nected to the utility power source (Figure 3.2).
2. Be sure that normal utility power source voltage
is available to transfer switch terminal lugs N1
and N2.
3. Set the generator’s AUTO/OFF/MANUAL switch to
AUTO.
4. Set the generator’s main circuit breaker to its ON
(or CLOSED) position.
With the preceding steps complete, the generator will
start automatically when utility source voltage drops
below a preset level. After the unit starts, loads are
transferred to the standby power source. Refer to
Section 3.4, “Sequence of Automatic Operation.”
3.3.1 12 VDC ACCESSORY OUTLET
The generator is equipped with a 12 VDC accessory
outlet in the generator control panel (Figure 3.1).
With the generator running or in standby mode, this
outlet may be used to temporarily power low power
accessories such as a work light, cell phone, radio or
any other automotive style accessory. This outlet is
capable of delivering a MAXIMUM of 7.5 amps. If the
accessory to be used through this circuit demands
too much power, the fuse that protects this circuit
will melt open and the circuit will not be functional.

This 12 VDC outlet draws power from the gen-
erator’s starting battery and extended use of
this outlet may drain the battery and the engine
may not start. This outlet should NOT be used
for battery charging.
