• Contact with hot parts during operation or immediately after stopping operation may cause burns. Do not touch
the hot parts.
• Immediately after operation, the oil and oil filter are hot. Start the replacement after the temperature goes down.
• Do not reuse the filter element, O-ring and gasket.
• When replacing the O-ring or gasket, check the fitting condition at the mounting surface to prevent it from being
twisted and broken.

dealer/distributor.
• Change the engine oil after 50 hours of operation has been reached for the first time.
• When the engine oil is replaced, replace the engine oil filter as well.
