PREPARING THE GENERATOR

Operator’s Manual

  STORE GASOLINE ONLY IN APPROVED 

CONTAINERS, IN WELL VENTILATED, 

UNOCCUPIED BUILDINGS AND AWAY FROM 

SPARKS OR FLAMES. 

 

DO NOT FILL THE FUEL TANK WHILE THE ENGINE 

IS HOT OR RUNNING, SINCE SPILLED FUEL 

COULD IGNITE IF IT COMES IN CONTACT WITH 

HOT PARTS OR SPARKS FROM IGNITION. DO NOT 

START THE ENGINE NEAR SPILLED FUEL. 

 

NEVER USE GASOLINE AS A CLEANING AGENT.

WARNING: DO NOT OVERFILL THE FUEL TANK, 

LEAVE ROOM FOR THE FUEL TO EXPAND.

WARNING: MAKE SURE YOU REVIEW EACH 

WARNING IN ORDER TO PREVENT FIRE HAZARD. 

 

DO NOT REFILL TANK WHILE ENGINE IS RUNNING 

OR HOT. 

  BEFORE FILLING FUEL, TURN THE ENGINE 

SWITCH TO (STOP) POSITION.

 

BE CAREFUL NOT TO ADMIT DUST, DIRT, WATER 

OR OTHER FOREIGN OBJECTS INTO FUEL.

  WIPE OFF SPILT FUEL THOROUGHLY BEFORE 

STARTING ENGINE. KEEP OPEN FLAMES AWAY.

USING FUEL STABILIZER
Fuel gets old, oxidizes, and breaks down over time. Adding 
a fuel stabilizer (not included) extends the usable life of fuel 
and helps prevent deposits from forming that can clog the 
fuel system. Follow fuel stabilizer manufacturer’s directions 
for correct ratio of stabilizer to fuel.

1. Mix fuel stabilizer and gasoline prior to filling the tank by 

using a gas can or other approved fuel container and shaking 

gently to combine.

NOTE: To control the amount of fuel stabilizer being added 

to the engine, always mix fuel stabilizer with gasoline 

before fueling the tank rather than adding fuel stabilizer 

directly into the generator’s fuel tank.

2. Replace and secure the fuel tank cap.

3. Start and run the engine for at least 5 minutes to allow 

stabilizer to treat the entire fuel system.

ETHANOL-BLENDED FUELS

NOTICE: Do not use E15 or E85 fuel in this product. It is a 

violation of federal law and will damage the unit and void 
your warranty. Only use unleaded gasoline containing up to 

10% ethanol.

ADDING FUEL

DANGER: RISK OF FIRE AND SERIOUS BURNS: 

NEVER REMOVE FUEL CAP WHEN UNIT IS 

RUNNING. SHUT OFF ENGINE AND ALLOW THE 

UNIT TO COOL AT LEAST FIVE MINUTES. REMOVE 

CAP SLOWLY.
