WARNING
• When changing the oil, apply the parking brake and secure the front and rear frames with the frame
lock bar.
• Immediately after the engine is stopped, its parts and oil are still very hot and may cause burn in-

• If the plug is removed, oil may spurt out, so turn it slowly to release the internal pressure, then re-
move it carefully.
