Note:
If oil level is too low, oil alert system
will keep engine from starting (see Oil Alert
System, page 5). Make sure oil level is full
before starting. See Engine Oil, page 6.
Before starting the engine, disconnect all
electric loads from generator.
STARTING
IMPORTANT:
The engine speed is preset.
The throttle is locked in preset position. Do
not adjust throttle. Preset position lets en-
gine run at 3600 RPM under load. The
engine must maintain 3600 RPM for gen-
erator to create correct voltage. Running
engine at lower speeds will damage genera-
tor and powered items.
IMPORTANT:
Never start generator with
electrical loads connected. Start engine be-
fore adding electrical loads.
1. Make sure gasoline tank is full. See
Fuel, page 6 for fuel information.
2. Pull choke button out (see Figure 14).
This closes the choke.
Note:
You may not need to close choke
if engine is warm or air temperature is
high.
WARNING: Only responsible
adults should use generator.
Never let anyone operate genera-
tor without proper instructions.
PRESTART
Operate generator on a firm, dry, and clean
surface. The surface must be level. Protect
generator from heavy dust, sand, dirt, rain, or
snow. Do not locate generator near standing
water and snow. Make sure area is well-vented.

3. Start the engine.
Turn the engine switch to the START
position (see Figure 15). Hold it there
until engine starts. When engine starts,
let switch return to the ON position.
IMPORTANT:
Do not use electric
starter more than five seconds. Starter
motor damage may occur. If engine
fails to start, release the switch and wait
ten seconds. After ten seconds, try start-
ing again.
Note:
If engine does not start, check
the oil in the crankcase. Add oil as nec-
essary. Be sure engine is on a level sur-
face. See Oil Alert System, page 5.
4. As engine warms up, the choke will au-
tomatically open.
