ASSEMBLY

Your generator requires some assembly and is ready for
use after it has been properly serviced with the
recommended oil and fuel. If you have any problems with
the assembly of your generator, please call the generator
helpline at 1-800-270-1408.

Remove Generator From Carton

• Set the carton on a rigid flat surface with “This Side Up”

arrows pointing upward.

• Carefully open the top flaps of the shipping carton.

• Cut carton corners from top to bottom at end of carton

near wheels. Lay that side of carton down flat.

• Remove all packing material, carton fillers, etc.

• Roll the generator out of the shipping carton.

BEFORE STARTING THE

ENGINE

Secure Handle

Secure the handle using the following steps:

• Loosen knobs of the handle.

• Raise the handle.

• Insert handle pins, if equipped (P/N B4135GS).

• Hand tighten knobs.

Add Engine Oil

• Place generator on a level surface.

• Use a long neck funnel OR remove the fuel tank as

described in “Fuel Tank”, when adding or changing oil.

• Refer to engine owner’s manual and follow oil

recommendations and instructions.

NOTE: Check oil often during engine break–in. Refer to
engine owner’s manual for recommendations.

NOTE: The generator assembly rotates on a prelubricated
and sealed ball bearing that requires no additional
lubrication for the life of the bearing.

Add Fuel

NOTE: This gasoline engine is certified to operate on
gasoline. Exhaust Emission Control System: EM (Engine
Modifications).

1.

Use clean, fresh, regular UNLEADED fuel with a
minimum of 85 octane. DO NOT use fuel which
contains Methanol. DO NOT mix oil with fuel.

2.

Clean area around fuel fill cap, remove cap.

3.

Slowly add regular unleaded fuel to fuel tank. Be
careful not to overfill. Allow about 1.5" of tank space
for fuel expansion (Figure 1).

4.

Install fuel cap and wipe up any spilled fuel.

Fuel Tank

As is common with all plastic fuel containers, the
removable fuel tank supplied with this generator may swell
or expand due to build-up of fuel vapors when the vent
knob is closed.This tank is designed and has been tested to
safely withstand pressure-buildup.The 'ballooning' condition

CAUTION

• Refer to engine manual for oil fill information.

• Damage to equipment resulting from failure to follow this

instruction will void warranty.

Any attempt to crank or start the engine before it has
been properly filled with the recommended oil will result
in equipment failure.

WHEN ADDING FUEL

• Turn generator OFF and let it cool at least 2 minutes before

removing fuel cap. Loosen cap slowly to relieve pressure in tank.

• Fill fuel tank outdoors.
• DO NOT overfill tank. Allow space for fuel expansion.
• Keep fuel away from sparks, open flames, pilot lights, heat, and

other ignition sources.

• DO NOT light a cigarette or smoke.

Fuel and its vapors are extremely flammable and
explosive.
Fire or explosion can cause severe burns or
death.
