=_ WARNING _=
/_ With the switch set to AUTO, the engine may
crank and start at any time without warning.
Such automatic starting occurs when utility
power source voltage droops below a preset
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 fuses before working on or
around the generator or transfer switch. Then,
place a "DO NOT OPERATE" tag on the genera=
tot panel and on the transfer switch.

A switch on the control panel (see Figure 3.1) per-
mits selection of the day and time for the system to
exercise. At the chosen time, perform the following
sequence to select the desired day and time of day

Example: If the "Set Exercise" pressed on Saturday
afternoon at 2:00 p.m., the generator will start and
exercise for approximately 12 minutes every Saturday
