Pull engine CHOKE knob outward to 

• 

“Full Choke”

 position 

(Figure 12).

Figure 12 - Choke Position

Choke

To start engine, press and hold the Start/Run/Stop switch in 

• 

the “Start” position. The engine will crank and attempt to start. 
When the engine starts, release the switch to the run position.

When the engine starts, push choke knob to “1/2 Choke” 

• 

position until the engine runs smoothly and then fully in to the 
“Run” position. If engine falters, pull choke knob back out to 
“1/2 Choke” position until the engine runs smoothly and then 
to “Run” position.

This generator is also equipped with a manual recoil starter 

• 

which may be used if the battery is discharged.

NOTE:

The switch must be in the RUN position.

To start manually, firmly grasp the recoil handle and pull slowly 

• 

until increased resistance is felt. Pull rapidly up and away to 
start engine. Then follow the same choke sequence listed 
above.

NOTE:

If engine fires, but does not continue to run, pull choke knob to 

“Full Choke” and repeat starting instructions.
IMPORTANT:

 Do not overload the generator. Also, do not overload 

individual panel receptacles. These outlets are protected against 

overload with push-to-reset-type circuit breakers. If amperage 

rating of any circuit breaker is exceeded, that breaker opens and 

electrical output to that receptacle is lost. Read “Don’t Overload the 

Generator” carefully.

2.9  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 Start/Run/Stop switch to “Off” position.

• 

Close fuel valve.

• 

2.10 LOW OIL PRESSURE SHUTDOWN SYSTEM

The engine is equipped with a low oil pressure sensor that shuts 

down the engine automatically when the oil pressure drops below 

5 psi. If the engine shuts down by itself and the fuel tank has 

enough gasoline, check engine oil level.

2.10.1 INITIAL START-UP

A delay built into the low oil shutdown system allows oil pressure 

to build during starting. The delay allows the engine to run for 

about 10 seconds before sensing oil pressure.

2.10.2 SENSING LOW OIL PRESSURE

If the system senses low oil pressure during operation, the engine 

shuts down.

2.10.3 RESTARTING

If trying to restart the engine within 10 seconds after it shuts down, 

the engine may NOT start. The system needs 5 to 10 seconds to 

reset.
If the engine is restarted after such a shutdown and the low oil 

pressure has not been corrected, the engine will run for about 10 

seconds as described above and then stop.

2.11 CHARGING A BATTERY

DANGER

  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.

DANGER

  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 13).
