3.1
BREAK-IN PROCEDURE
Once the unit has been installed and all electrical
checks have been made, it is strongly recommended
that the following "Break-in Procedure" be completed
to ensure correct generator operation in the future.
1. Set the generator's Auto/Off/Manual switch to
AUTO.
2. Turn OFF the utility power supply to the transfer
switch using the means provided (such as a utili-
ty main line circuit breaker).
3. The unit will start, and the transfer switch will
transfer to standby.
4. Using the transfer switch's built-in emergency
load center, turn on circuits to load the generator
to approximately 25% rated load and run the unit
for one hour.
5. Run the unit for one hour at 50% rated load.
6. Run the unit for one hour at 75% rated load.
7. Run the unit for one hour at 100% rated load.
8. Turn ON the utility power supply to the transfer
switch, which will allow the transfer switch to
transfer back to utility power. The unit will con-
tinue to run for one minute and then shut down.
9. Allow the unit to cool.
10. Drain the oil and remove the oil filter. Replace the
oil filter according to Section 4.4, "Changing the
Oil Filter" (Page 16). Replace the oil with synthet-
ic oil as recommended in Section 4.3, "Changing
the Engine Oil" (Page 15).
11. The generator is now ready for service.

USING THE AUTO/OFF/MANUAL
SWITCH (FIGURE 3.1)
3.2.1 "AUTO" POSITION
Selecting this switch position activates fully automatic
system operation. It also allows you to start and exercise
the engine every seven days with the setting of the exer-
cise timer (see Section 3.6, Page 14). 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.
Section 3 — Operation
Air-cooled 8.5 kW Generator
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.

EXERCISE
TIME
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 the fuse 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 connected
to the utility power source (Figure 3.2, Page 14).
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
"Sequence of Automatic Operation" (Page 14).
