If it is necessary to go under the work equipment or the
machine to carry out service and maintenance, support the
work equipment and machine securely with blocks and

It is extremely dangerous to work under the machine if the
track shoes are lifted off the ground and the machine is
supported only with the work equipment. If any of the
control levers is touched by accident, or there is damage

Never work under the work equipment or the machine.
