Empty the dump body before you jack up the machine.
Raising with a Jack and Supporting with Blocks
Place the jack in a location that will sustain the weight of the machine such as a frame member. The frame member should be parallel to the ground. The head of the jack should be against a flat surface. Use a jack which will support the weight of the machine.

A suitable place for jacking up the machine is at callout (1). These locations are part of the front frame and the rear frame.
After you have jacked up the machine to the height that is required for you to perform the work that is needed, place wood blocks for cribbing at suitable locations under the machine. The wood blocks should be placed on a level ground. The wood blocks should provide a large base for support. The wood blocks should be no less than 15 cm (6 inches) wide,15 cm (6 inches) high, and 76 cm (30 inches) long. You should use only wood blocks which will support the weight of your machine.
Once the wood blocks are in place, lower the jack until the machine is supported by the blocks.
Make sure that the machine is stable before you proceed to work on the machine.
Note: A stand is available from your Caterpillar dealer which may be substituted for wood blocks that are used for cribbing. Stands should only be used on a concrete surface. Consult your Caterpillar dealer for further information.
Raising and Supporting with a Lift Stand
A Lift Stand is available from your Caterpillar dealer. Consult your Caterpillar dealer for further information. The Lift Stand combines lifting and supporting functions. Two of these Lift Stands should be used if you are lifting both sides of the machine. Lift Stands should only be used on concrete surfaces.
Place the Lift Stand in a location that will sustain the weight of the machine such as a frame member. The frame member should be parallel to the ground. The head of the Lift Stand should be against a flat surface. Use a Lift Stand which will support the weight of the machine.
Make sure that the machine is stable before you proceed to work on the machine.
