Operating Automatic Idle Control
This switch is designed to greatly improve fuel economy.
When this switch is turned ON, the engine will only
run at its normal high governed engine speed when
electrical loads are connected.When an electrical load is
removed, the engine will run at a reduced speed.
With the switch off, the engine will run at the normal
high engine speed. Always have the switch off when
starting and stopping the engine.
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:
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 “12-VOLTS D.C.”.
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 (–) battery terminal (Figure 6).
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.
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
manual).
4. Check oil level daily or after every eight (8) hours of
operation.
5. Maintain generator following “Maintenance Schedule”
in engine manual.
6. Shelter unit from elements.

BSPP Generator
• 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.
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.
