very hot and can cause injuries through burning. Wait until
they have cooled down before starting work.
 Wear rubber gloves and hold the oil drain tray underneath the
drain in a way that prevents the oil from making contact with
your body.
ATTENTION
 Performing maintenance on a machine that is not properly
parked and secured may cause severe accidents!
 Park the machine on solid, level ground. Secure the machine
before beginning maintenance work.
