Battery Connection; Fuel Supply System - Briggs & Stratton 40221 Installation, Start-Up And Operator's Manual

Battery Connection

The Home Generator System is supplied with a 12 Volt DC,
AGM type, 33 Amp-Hour, valve regulated battery. It is a
sealed, lead-acid rechargeable battery. It is installed in the
unit and the battery cables are connected at the factory.The
unit's 15 Amp fuse, which isolates the battery and prevents
the unit from starting, has been removed for shipping.The
battery will lose some charge charge prior to installation of
the generator. If battery voltage is below 12 Volts, charge the
battery.
IMPORTANT: If battery voltage is below 5 Volts, it may
not take a charge and you will need a new battery.
Charging the Battery
If it is necessary to charge the battery, proceed as follows:
1. Pull service disconnect from disconnect box.
2. Remove the 15 Amp fuse from the control panel.
3. Disconnect the negative battery cable to the negative
battery terminal (indicated by NEGATIVE, NEG, or (-).
CAUTION
Failure to disconnect negative battery cable will result
in equipment failure.
• DO NOT attempt to jump start the battery.
• Damage to equipment resulting from failure to follow this
instruction will void warranty.
4. Charge battery with battery charger at 2 Amps until
battery holds 12 Volts.
DANGER
Storage batteries give off explosive hydrogen gas
during recharging.
Slightest spark will ignite hydrogen and cause
explosion.
Battery electrolyte fluid contains acid and is
extremely caustic.
Contact with battery contents will cause severe
chemical burns.
A battery presents a risk of electrical shock and
high short circuit current.
• DO NOT dispose of battery in a fire.
• DO NOT allow any open flame, spark, heat, or lit cigarette
during and for several minutes after charging a battery.
• DO NOT open or mutilate the battery.
• Wear protective goggles, rubber apron, and rubber gloves.
• Remove watches, rings, or other metal objects.
• Use tools with insulated handles.
INSTALLATION
NOTE: With the battery installed and utility power
available to the Automatic Transfer Switch, the battery
receives a trickle charge whenever the engine is not
running.This process may take up to 72 hours to fully
charge a battery from 5 Volts.The trickle charge cannot be
used to recharge a battery that is completely discharged.
5. Connect the negative battery cable to the negative
battery terminal (indicated by NEGATIVE, NEG, or (-).
6. Ensure hardware on both positive and negative battery
terminals is secure.
7. Reinstall the 15 Amp fuse in the control panel.
Installing the 15A fuse could cause the engine to start.
• DO NOT install the 15 Amp fuse until all plumbing and wiring
has been completed and inspected.
8. Reinstall service disconnect in disconnect box.
Servicing the Battery
If it is necessary to service the battery, proceed as follows:
1. Pull service disconnect from disconnect box.
2. Remove the 15 Amp fuse from the control panel.
3. Service or replace battery as required.
4. Connect the red battery cable to the battery positive
terminal (indicated by POSITIVE, POS, or (+).
5. Connect the negative battery cable to the negative
battery terminal (indicated by NEGATIVE, NEG, or (-).
6. Ensure hardware on both positive and negative battery
terminals is secure.
7. Reinstall the 15 Amp fuse in the control panel.
8. Reinstall service disconnect in disconnect box.

Fuel Supply System

Ensure that all fuel pipe connections are tight, secure and
without leaks.
Ensure that all gas line shutoff valves are OPEN and that
