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