Guardian Air-cooled Generators
1.1 BEFORE INITIAL START-UP
Before starting, complete the following:
1. Set the generator's Auto/Off/Manual switch to the
OFF position.
2. Turn OFF the utility power supply to the transfer
switch using the means provided (such as the
utility main line circuit breaker).
3. Check the engine crankcase oil level and, if nec-
essary, fill to the dipstick FULL mark with the
recommended oil. Do not fill above the FULL
mark.
4. Check the fuel supply. Gaseous fuel lines must
have been properly purged and leak tested in
accordance with applicable fuel-gas codes. All
fuel shutoff valves in the fuel supply lines must be
open.
Never operate the engine with the oil level
below the "Add" mark on the dipstick. Doing
this could damage the engine.
1.2 BATTERY INSTALLATION
Fill the battery with the proper electrolyte fluid if nec-
essary and have the battery fully charged before
installing it.
Before installing and connecting the battery, complete
the following steps:
1. Set the generator's Auto/Off/Manual switch
to OFF .
2. Turn off utility power supply to the transfer
switch.
If the Auto/Off/Manual switch is not set to its
OFF position, the generator can crank and start
as soon as the battery cables are connected. If
the utility power supply is not turned off,
sparking can occur at the battery posts and
cause an explosion.
Battery cables were factory connected at the genera-
tor (Figure 1.1). Connect cables to battery posts as
follows:
1. Connect the red battery cable (from starter con-
tactor) to the battery post indicated by a positive,
POS or (+).
2. Connect the black battery cable (from frame
ground) to the battery post indicated by a nega-
tive, NEG or (—).
Damage will result if battery connections are made
in reverse.
