the engine stop switch to the “o󰀨” position. Remove the
fuel cap to allow air into the fuel tank and then screw the
fuel cap back onto the fuel tank. Try starting the engine.

NOTE: The tires are inated when shipped, but they invariably lose some pressure
between the point of manufacturing and your purchase. Always inate the tires to the
correct PSI before rst time use.
Please read the specication sheet to get the information of tire pressure. Using a
bicycle-style tire pump to inate the tire to the PSI indicated on the sidewall of the tire.
Note: The pressurized air supplies found at gasoline stations are designed to inate
high-volume automobile tires. If you decide to use such an air supply to inate your
tires, rst make sure the pressure gauge is working, then use very short bursts to
inate to the correct PSI. If you inadvertently over-inate the tire, release the excess
pressure immediately.
