Press the button on control unit (62) one time in order to accept the new value.
Repeat Step 3 for the next parameter value.
Scroll through the parameter list to value "--". Wait for a few seconds. The parameter value on the control unit will stop being displayed.Testing and Adjusting
The following procedure is used to adjust the maximum pressure to the blade cylinders. The maximum pressure is controlled by two signal limiter valves in the blade control valve. One signal limiter valve controls the maximum pressure for lifting the blade. The other signal limiter valve controls the maximum pressure for lowering the blade.Before testing or adjusting the signal limiter valves, ensure that the standby pressure and high pressure cutoff are adjusted correctly for the implement pump.Reference: For more information on the standby pressure, refer to Testing and Adjusting, RENR3031, "Implement Pump Standby Pressure - Test and Adjust" for the machine that is being serviced.Reference: For more information on the high pressure cutoff, refer to Testing and Adjusting, RENR3031, "Implement Pump High Pressure Cutoff - Test and Adjust" for the machine that is being serviced.

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 and cause serious injury and possible death. If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury.Always use a board or cardboard when checking for a leak.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
Ensure that the hydraulic oil in the system is at normal operating temperature. Park the machine on a level surface.
