Battery
This unit is of negative ground. DO NOT connect in reverse. Always maintain battery fluid level between the specified marks. DO NOT over fill. Battery life will be shortened if the fluid level is 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 malfunction. 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 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, 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 make sure that the battery cables (Figure 17) are properly connected to the battery terminals as shown below.
CAUTION
ALWAYS disconnect the negative terminal FIRST and reconnect negative terminal LAST.
Figure 17. Battery Connections
When connecting the battery do the following:
1.Place a small amount of battery terminal treatment compound around both battery terminals. This will ensure a good connection and will help prevent corrosion around the battery terminals.
2.Connect the red cable to the positive terminal of the battery and the black cable to the negative terminal of the battery.
.
NOTICE
If the battery cable is connected incorrectly, electrical damage to the generator will occur. Pay close attention to the polarity when connecting the battery.
CAUTION
Inadequate battery connections may cause poor starting of the generator, and create other malfunctions.
Alternator
The polarity of the alternator is negative grounding type. When an inverted circuit connection takes place, the circuit will short instantaneously resulting in alternator failure.
DO NOT put water directly on the alternator. Water in the alternator can cause corrosion and damage.
Wiring
Inspect the generator for bad, worn electrical wiring or connections. If any wiring or connections are exposed (insulation missing), replace wiring immediately.
Piping and Hose Connection
Inspect all piping, oil hose, and fuel hose connections for fatigue, wear and tightness. Tighten all hose clamps and check hoses for leaks.
If any hose (fuel or oil) lines are defective, replace them immediately.
