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.
DO NOT over fill. Check to see whether the battery
cables are loose. Poor contact may result in poor starting
or malfunctions. Always keep the terminals firmly
tightened. Coat the terminals with an approved battery
terminal treatment compound. Replace battery with only
recommended type battery. The battery type used in this
generator is BCI Group 22F (CCA:410).
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
ALWAYS be sure the battery cables (Figure 14) are
properly connected to the battery terminals as shown
below. RED cable is connected to the positive terminal
of the battery, and the BLACK cable is connected to the
negative terminal of the battery.
CAUTION
ALWAYS disconnect the negative terminal FIRST and
reconnect negative terminal LAST.

SELECTING THE WELDING CABLE
The welding cable should be larger in size as it becomes
longer or its current becomes higher. Prepare a cable with
suitable size by referring to Table 14.
WELDING CABLE AND POLARITIES
1. ALWAYS attach terminal ring connectors (Figure 15) to
2. NEVER connect exposed wires (Figure 15) directly to
NEGATIVE
3. Connect the welding cables to the welder output

the welder output terminals. Exposed wiring may cause
shocks or di-electric breakdown from poor contact.

terminals located just below the control panel. The
output terminals are marked (+) and (–) polarities.
Select the appropriate polarities according to the
application. Reference Table 15.
DANGER
NEVER allow the welding cable terminal to come in contact
with the adjacent welding terminal or the welder-generator
frame when the machine is in use. The possibility exists
of electrical shock or short circuit which could cause a
fire resulting in severe bodily harm and damage to the
equipment.
