SPECIFICATION

OPERATION

PREPARATION AND CHECK BEFORE OPERATION

CAUTION

NO MACHINE OIL IN THE ENGINE, PLEASE FILL THE MACHINE OIL IN!

Check engine oil level

• Unscrew the oil dipstick to check whether the engine oil is within the range of specified limit. If the oil level is too low, add the engine oil from filling hole till the specified height.

CAUTION

• Using different brand engine oil will vary according to environment temperature.
• Our recommended engine oil is SAE 10W-30.

1. Oil dipstick hole
2. Highest oil level
3. Lowest oil level

Check fuel level:

Open the fuel tank cover and check the fuel level. If the level is too low, add the fuel from filling-hole till the oil level reaching the red stop plate inside of the strainer. Our recommended fuel brand is standard gasoline (unleaded gasoline is as standard). Do not mix the gasoline with the engine oil. Do not use the gasoline with foreign materials.
