• Immediately after the machine is stopped, its parts and oil are still very hot and may cause burn in-
jury. Accordingly, wait until they have cooled down before starting the work.
• The undercover is heavy. Never try to open or close the cover when you are directly under it. When
removing bolts (3), perform the work from the rear of the cover so that you can easily get out of the
