BSPP Generator
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.
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.Check fluid level in all battery cells. If necessary, add ONLY distilled water to cover separators in battery cells. DO NOT use tap water.
2.If battery is equipped with vent caps, make sure they are installed and are tight.
3.If necessary, clean battery terminals.
4.Connect battery charge cable connector plug to panel receptacle identified by the words
5.Move idle control switch to “Off” position.
6.Connect battery charge cable clamp with red handle to the positive (+) battery terminal (Figure 6).
7.Connect battery charge cable clamp with black handle to the negative
8.Start engine. Let engine run while battery recharges.
9.When battery has charged, shut down 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.
How to Use the Battery Charger
Use battery float charger jack to keep the starting battery charged and ready for use. Battery charging should be done in a dry location, such as inside a garage.
1.Plug charger into unit’s “Battery Float Charger” jack, which is located on the control panel (Figure 7). Plug battery charger into a 120 Volt AC wall receptacle.
Figure 7 — Battery Charger Jack
2.Unplug charger from unit and wall outlet when generator is being started and while in operation.
3.Keep charger plugged in when generator is not in use to prolong battery life.The charger has a built in float equalizer and will not overcharge battery, even when plugged in for an extended period of time.
