Stopping The Engine; Low Oil Level Shutdown System; Sensing Low Oil Level; Charging A Battery (Electric Start Units Only) - Generac Power Systems GP Series Owner's Manual

2.10 STOPPING THE ENGINE

• Shut off all loads, then unplug the electrical loads from generator
panel receptacles. Never start or stop the engine with electrical
devices plugged in and turned on.
• Let engine run at no-load for several minutes to stabilize the
internal temperatures of engine and generator.
• Move Run/Stop switch to
• Close fuel valve.

2.11 LOW OIL LEVEL SHUTDOWN SYSTEM

The engine is equipped with a low oil level sensor that shuts down the
engine automatically when the oil level drops below a specified level. If
the engine shuts down by itself and the fuel tank has enough gasoline,
check engine oil level.

2.11.1 SENSING LOW OIL LEVEL

If the system senses a low oil level during operation, the engine shuts
down. The engine will not run until the oil has been refilled to the
proper level.
2.12 CHARGING A BATTERY (ELECTRIC START
UNITS ONLY)
Storage batteries give off explosive hydrogen
gas while recharging. An explosive mixture will
remain around the battery for a long time after
it has been charged. The slightest spark can
ignite the hydrogen and cause an explosion.
Such an explosion can shatter the battery and
cause blindness or other serious injury.
Do not permit smoking, open flame, sparks or
any other source of heat around a battery. Wear
protective goggles, rubber apron and rubber
gloves when working around a battery. Battery
electrolyte fluid is an extremely corrosive
sulfuric acid solution that can cause severe
burns. If spill occurs flush area with clear water
immediately.
Use battery charger plug to keep the battery charged and ready for
use. Battery charging should be done in a dry location.
1. Plug charger into "Battery Charger Input" jack, located on the
control panel. Plug wall receptacle end of the battery charger into
a 120 Volt AC wall outlet (Figure 15).
2. Unplug battery charger from wall outlet and control panel jack
when generator is going to be in use.
