PRE-OPERATION CHECK ! WARNING: Be sure to check the generator is on a level surface with the engine stopped. CHECK THE ENGINE OIL LEVEL ! NOTICE: Do not use non-detergent oil or 2-stroke engine oil. It will void the warranty and will shorten the engine's service life. • Use a high-detergent, premium quality 4-stroke engine oil. • Change oil in a new engine within the first 4 to 6 hours of operation to clean manufacturing debris and contamination during break-in. • Use SAE 10W-30 or 15W-30 viscosity oil. 1.
V Hz Kw Pg.
CHECK THE FUEL LEVEL ! NOTE: Use automotive unleaded regular gasoline only. • Never use an oil/gasoline mixture or dirty fuel. • Avoid getting dirt, dust or water in the fuel tank. 1. If the fuel level is low, refill the tank. 2. After refueling, tighten the fuel cap securely ! WARNING: Temperature changes affect the volume of gasoline. Gasoline expands at a rate of 0.15939 cubic inches per gallon for every degree (F) that the temperature increases.
! NOTE: Before buying fuel from an unfamiliar station, determine if the fuel contains ethanol and if it does, confirm the type and percentage of ethanol used. If you notice any undesirable operating symptoms while using a gasoline that contains ethanol, or one that you think contains ethanol, replace it with a gasoline that you know has the proper blend. Fuel Tank Capacity: 10.5L Pg.
OPERATION INSTRUCTIONS STARTING THE ENGINE ! NOTE: When starting the generator after adding fuel for the first time or after long term storage, or after running out of fuel, turn the fuel valve to the ON position, then wait for 10 to 20 seconds before starting the engine. 1. Turn on the fuel valve. 2. Push the engine switch on the control panel to the “ON” position. 3. Pull the choke lever to the “RUN” position. 4.
