WORK UNDER THE MACHINE G 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 stands strong enough to support the weight of the work equipment and machine. G It is extremely dangerous to work under the machine if the track shoes are off the ground and the machine is sup- ported only by the work equipment. If the control levers are touched by mistake, or there is a hazard to the hydrauli- cline, the work equipment or the machine may suddenly descend. This is extremely dangerous. Never work under the machine if the machine is not properly supported by blocks or stands. 2-37
