Storage and transportation

Storage
The generating set should be started at least once every 2 weeks and allowed to run for at least 20 minutes.Follow the instructions below for longer term storage if the generating set will be out of service for 2 months or more.
DANGER
Fire or explosion
Gasoline is highly flammable and extremely explosive.
Empty the fuel tank and shut off fuel valve before storing or transporting this generating set.

1. Allow the generating set to cool completely before storage.
2. Clean the generating set according to instructions in Maintenance section.
3. Drain all fuel completely from the fuel tank,fuel hose and carburetor to prevent gum from forming.
4. Turn the Transfer switch in “STOP”position to cut off the fuel.
5. Remive the oil drain plug to drain out the oil(See“Engine oil” section).
6. Remove the spark plug and pour about 15 ml of fresh oil into the cylinder.Pull the recoil starter slightly to distribute the oil and lubricate the cylinder.And then attach the spark plug.
7. Store the unit in a clean,dry area out of direct sunlight.
8. please disconnect the battery.
9. Transportation
   When generator transportation or short term storage,the generator should be in the normal operating position and fixed vertically to prevent fuel leakage.The combination switch should be in the”stop” position and knob of the fuel cap should be turned to the “OFF”position.

WARNING
When transporting:
Do not overfill the tank.Do not operate the generating set while it is on vehicle.
Take the generating set off the vehicle and use it in a well-ventilated place.Avoid a place exposed to direct sunlight when putting the generating set on a vehicle.
Iif the generating set is left in an enclosed vehicle for many hours,high temperature inside the vehicle could cause fuel to vaporize resulting in a possible explosion.Do not drive on a rough road for an extended period with the generating set on board.If you must transport the generating set on a rough road,drain the fuel from the generating set beforehand.
