Briggs & Stratton PRO4000 Portable Generator User Manual


 
Stopping the Engine
1. Turn OFF and unplug all electrical loads from generator
panel receptacles. NEVER start or stop engine with
electrical devices plugged in and turned ON.
2. Move idle control switch to “Off” position.
3. Let engine run at no-load for several minutes to
stabilize internal temperatures of engine and generator.
4. Push engine rocker switch to stop position (O).
5. Move fuel valve to “Off” position.
Operating Automatic Idle Control
This feature 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 electrical loads are 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.
Oil Pressure Shutdown
If engine oil pressure drops below a preset level, an oil
switch will stop the engine. Check oil level with dipstick.
If oil level is between ADD and FULL mark on dipstick:
1. DO NOT try to restart the engine.
2. Contact a Briggs & Stratton Authorized Dealer.
3. DO NOT operate engine until oil pressure is corrected.
If oil level is below ADD mark on dipstick:
1. Add oil to bring level to FULL mark.
2. Restart engine and if the engine stops again a low oil
pressure condition may still exist. DO NOT try to restart
the engine.
3. Contact a Briggs & Stratton Authorized Dealer.
4. DO NOT operate engine until oil pressure is corrected.
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 “12V 10A D.C.”
5. Connect battery charge cable clamp with red handle to
the positive (+) battery terminal.
6. Connect battery charge cable clamp with black handle
to the negative (–) battery terminal.
7. Start engine. Let engine run while battery recharges.
8. 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.

WARNING
Backfire, fire or engine damage could occur.
DO NOT stop engine by moving choke control to “Choke
position.
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.
