PERIODIC MAINTENANCE AND ADJUSTMENT
● Fuel system service
• Use only unleaded gasoline. The use of leaded gasoline will cause severe damage to internal engine parts, such as
the valves and piston rings, as well as to the exhaust system.
• Replace the fuel filler cover every two years or if cracked or damaged.
• Check the fuel filter if clogged or damaged every 12000 km (7500 mi).
● Battery service
• Check the condition and service every 3 months.
• Recharge the battery immediately if the voltage is less than 12.4 V.
• If the battery tends to discharge, replace it immediately.
• If the vehicle will not be used for more than one month, remove the battery, fully charge it, and then place it in a cool,
dry place.
