WARNING
• Immediately after the engine is stopped, its parts and oil are still very hot, and may cause burn in-
jury. Wait for the temperature to go down, and then start the work.
• If the oil filler cap is removed without releasing the internal pressure, oil will spurt out, so turn the
oil filler cap slowly to release the internal pressure, then remove it carefully.
• Loosen the bolts (4 pieces) gradually, otherwise the cover (1) may jump out due to the spring (2)
when removing the cover.
