R
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.
WARNING: Only responsible
adults should use generator.
Never let anyone operate genera-
tor without proper instructions.
Note: If oil level is too low, oil alert system
will keep engine from starting (see Oil Alert
System, page 4). Make sure oil level is full
before starting. See Engine Oil, page 6.
Before starting the engine, disconnect all
electric loads from generator.
You may need to bleed fuel line to remove
trapped air
• if starting engine for first time
• if starting engine after allowing generator
to run out of fuel
Follow the directions below to bleed fuel line.
BLEEDING FUEL LINE
1. Loosen fuel line clamp and remove fuel
line from engine. Place open end of fuel
line over a clean container to catch any
fuel spilled in step 3, below.
2. Move fuel valve lever to the "O" (open)
position (see Figure 15).
3. Allow air to bleed from line. When fuel
exits fuel line in a steady stream, reat-
tach fuel line to engine.
4. Add spilled fuel back into fuel tank.
STARTING
CAUTION: You must always
run the engine at full speed. Do
not run engine at lower speeds.
At full speed, the engine runs at
3600 RPM under load. The en-
gine must maintain 3600 RPM for
generator to create correct volt-
age. Running engine at lower
speeds will damage generator
and powered items.
