Personal injury or death can result from sudden machine movement. Sudden movement of the machine can cause injury to persons on or near the machine.



To prevent injury or death, make sure that the area around the machine is clear of personnel and obstructions before operating the machine.

Personal injury can result from hydraulic oil pressure and hot oil. ydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system. Make sure all of the attachments have been lo!ered, oil is cool before removing any components or lines. "emove the oil filler cap only !hen the engine is stopped, and the filler cap is cool enough to touch !ith your bare hand.

#scaping fluid under pressure, even a pinhole si$e leak, can penetrate body tissue, causing serious injury, and possible death. %f fluid is injected into your skin, it must be treated immediately by a doctor familiar !ith this type of injury. &l!ays use a board or cardboard !hen checking for a leak.

'(T%C# Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. )e prepared to collect the fluid !ith suitable containers before opening any compartment or disassembling any component containing fluids. "efer to Special Publication, '#'*+, /ealer Service Tool Catalog for tools and supplies suitable to collect and contain fluids on Cat products. /ispose of all fluids according to local regulations and mandates.
