BATTERY
This unit is of negative ground. DO NOT connect in reverse.
Always maintain battery fluid level between the specified
marks. Battery life will be shortened, if the fluid levels are
not properly maintained. Add only distilled water when
replenishment is necessary.
Check to see whether the battery cables are loose. Poor
contact may result in poor starting or malfunctions. Always
keep the terminals firmly tightened. Coating the terminals
with an approved battery terminal treatment compound
will help prevent corrosion. Replace battery with only
recommended type battery.
The battery is sufficiently charged if the specific gravity
of the battery fluid is 1.28 (at 68° F). If the specific gravity
should fall to 1.245 or lower, it indicates that the battery is
dead and needs to be recharged or replaced.
Before charging the battery with an external electric source,
be sure to disconnect the battery cables.
BATTERY CABLE INSTALLATION
NOTICE
Inadequate battery cable connections may cause poor

When connecting battery do the following:
1. NEVER use worn or damaged battery cables. Replace
2. Place a small amount of battery terminal treatment
POLARITY
The polarity of the battery is extremely important. When an
inverted circuit connection takes place, the circuit will be in
short circuit instantaneously resulting in possible damage
to the control box electronics and starter.
When connecting the battery cables to the battery terminals
be sure to check the polarity.

compound around both battery terminals. This will
ensure a good connection and will help prevent
corrosion around the battery terminals.
NOTICE
If the battery cables are connected incorrectly, electrical
damage to the generator will occur. Pay close attention
to the polarity markings on the battery when connecting
the battery cables.
