WARNING
Immediately after the engine is stopped, its parts and oil are still very hot, and may cause burn injury.
Accordingly, wait until they have cooled down before starting the work.
REMARK
• When checking the oil level after the engine has been operated, wait for at least 15 minutes after stopping
the engine before checking.
If the machine is inclining, make it level before checking.
• When the ambient temperature is low, water or emulsified matter may stick to the dipstick, fuel filler cap,
etc. or the drained oil may be milky white because of water vapor in the blowby gas. However, if the coolant
level is normal, it is not a problem.
