Check the crankcase oil level daily.
Unscrew the plug dipstick and remove it from the crankcase.
Wipe off the dipstick and return it to the crankcase. DO NOT screw it back into the crankcase.
Remove the dipstick again and check the oil level. The level must be kept near the full (F) mark on the dipstick.
DO NOT overfill. The oil level must never be higher than the full (F) mark on the dipstick.
If the oil level is slightly above or below the low (L) mark, add oil to the crankcase through the dipstick hole. Use

Return the plug-dipstick to the hole and screw it down securely.
