When changing attachments, tires or perform-
ing other service, use correct jacks and sup-
ports. Make sure machine is parked on a solid,
level surface such as a concrete floor. Prior to
raising machine, remove any attachments that
may interfere with the safe and proper raising of
the machine. Always chock or block wheels. Use
jack stands to support the raised machine. If the
machine is not properly supported by jack
stands, the machine may move or fall, which
