Charging a Battery

Charging a Battery

Your generator has the capability of recharging a discharged 12 Volt automotive or utility style storage battery. DO NOT use the unit to charge any 6 Volt batteries. DO NOT use the unit to crank an engine having a discharged battery.

To recharge 12 Volt batteries, proceed as follows: DANGER

Storage batteries give off explosive hydrogen gas during recharging.

Hydrogen gas stays near battery for a long time after battery has been charged.

Slightest spark will ignite hydrogen and cause explosion.

You can be blinded or severely injured.

Battery electrolyte fluid contains acid and is extremely caustic.

Contact with battery fluid will cause severe chemical burns.

DO NOT allow any open flame, spark, heat, or lit cigarette during and for several minutes after charging a battery.

Wear protective goggles, rubber apron, and rubber gloves.

To recharge 12 Volt batteries, proceed as follows:

1.If necessary, clean battery posts or terminals.

2.Check fluid level in all battery cells. If necessary, add ONLY distilled water to cover separators in battery cells. DO NOT use tap water.

3.If the battery is equipped with vent caps, make sure they are installed and are tight.

4.Connect battery charge cable connector plug to the 12 Volt DC panel receptacle.

5.Connect battery charge cable clamp with red handle to battery post or terminal indicated by Positive, POS or (+).

Positive

Negative

6.Connect battery charge cable clamp with black handle to battery post or terminal indicated by Negative, NEG, or ().

7.Start generator as described in Starting The Engine. Let the engine run while battery recharges.

8.When battery has charged, shut down engine as described in Stopping The Engine.

NOTE: Use an automotive hydrometer to test battery state of charge and condition. Follow the hydrometer manufacturer’s instructions carefully. Generally, a battery is considered to be at 100% state of charge when specific gravity of its fluid (as measured by hydrometer) is 1.260 or higher.

Cold Weather Operation

Under certain weather conditions (temperatures below 40°F [4°C] combined with high humidity), your generator may experience icing of the carburetor and/or the crankcase breather system. To reduce this problem, you need to perform the following:

1.Make sure generator has clean, fresh fuel.

2.Open fuel valve (turn valve to open position).

3.Use SAE 5W-30 oil (synthetic preferred, see engine operator’s manual).

4.Check oil level daily or after every eight (8) hours of operation.

5.Maintain generator following maintenance schedule in engine operator’s manual.

6.Shelter unit from elements.
