1. ENGINE OIL
Use 4-stroke engine oil, API service classification SJ class or equivalent. Check the API service label on the oil container to be sure
it includes the letters SJ class or equivalent.
SAE 10W-30 is recommended for general use. Other viscosities shown in the chart may be used
when the average temperature in your area is within the indicated range.
Oil level check
1. Remove the dipstick and clean it with a rag.
2. Reinsert the dipstick into the oil filling hole without screwing it in. Pull the dipstick out and
check oil level.
3. If the oil level is too low, add the recommended engine oil up to the oil filling neck.
4. Reinstall the dipstick.
Oil Capacity = .37 qt/11.8 oz. (0.35L)
Running the engine with insufficient engine oil may damage the engine severely and would not be covered under warranty.
2. AIR CLEANER
Remove the air cleaner cover and check the air filter to make sure it is clean and not damaged. Clean or replace it as necessary
(see the "Maintenance" section for maintenance of the air filter).
Never run the engine without the air filter and cover installed or damage to the engine could result. Damage to the engine
by not having the air filter and cover installed is not covered under warranty.
