PLUG 2538111 - Caterpillar

Personal injury or death can result from escaping fluid under pressure.Escaping fluid under pressure, even a very small pin-hole size leak, can penetrate body tissue, causing serious injury, and possible death.Always use a board or cardboard when checking for a leak.Do not check for pin hole leaks in pump or motor hoses during a steer stall condition. If fluid is injected into your skin, it must be treated by a doctor familiar with this type of injury immediately.
Personal injury or death can result from sudden machine movement.Sudden movement of the machine or release of oil under pressure can cause injury to persons on or near the machine.To help prevent possible injury, perform the procedure that follows before testing and adjusting the hydraulic and steering system:
This procedure is used to verify the engine stall speed.
Move the machine to a hard, level surface that is free of debris.
Permit only one operator on the machine. Keep all other personnel away from the machine.
