Voltmaster Engine-Driven Generators
■ Even when batteries are not in operation, self-discharge generates
hydrogen gas that can explode. Always store and work on batteries
in a well ventilated area.
■ Always wear proper eye, face, and hand protection when working
on or near batteries. Battery acid will cause severe eye damage and
skin burns. If contact with battery acid occurs, immediately flush
with water and seek medical help.
■ Keep all sparks, flames, and cigarettes away from batteries at all
times.
■ Never lean over batteries when testing or charging.
■ Keep battery vent caps tight and level, except when watering
batteries.
■ Avoid tilting the generator with a battery installed.
■ To prevent short circuits and sparks, exercise caution when working
with metallic tools or conductors near batteries.
■ To reduce the risk of sparks, ensure connectors make good contact
with battery terminals. Replace cables that appear suspicious or
have visible cracks or bare wires.
■ NEVER connect or disconnect battery cables from batteries or the
generator while the engine is cranking or operating.
■ ALWAYS ensure battery connections are the correct polarity. The red
cable is positive (+) and the green cable is negative (–).
■ Keep battery terminals clean and terminal connections tight.
■ After making connections at the battery terminals, coat the
terminals with a light application of petroleum jelly or grease to
retard corrosion.
Charging
■ Observe battery safety precautions (see “Safety” on page 29).
■ To lengthen battery life and to prevent freezing, always keep
batteries fully charged.
■ The charging circuit is operational during engine cranking and
running. The charging circuit is not designed to recharge a dead
battery but only to maintain the charge in the battery. If the
generator is not in regular, daily use, check battery voltage once a
week.
