Suction head in the fuel tank
Check the fuel filter (1) periodically. To check the fuel filter, follow the steps below:
1. Remove the fuel tank cap, drain the fuel to empty the tank. Check the tank
inside for any foreign materials. If any, remove them.
2. Pull out the suction head by using a wire hook through the tank opening.
3. If the fuel filter clogged slightly, clean it. To clean it, gently shake and tap it in
fuel. To avoid damage, do not squeeze or rub it. The fuel used for the cleaning
must be disposed in accordance with the method specified by regulations in
your country.
If the fuel filter became hard or heavily clogged up, replace it.
