Manual Extract CHECKING THE PRESSURE SETTING OF THE RELIEF VALVE

1. Park the machine on a level surface. Lower the loader bucket to the floor. Lower any attachments to the floor.
2. The oil must be at operating temperature. To heat the oil, do the following steps: A. With the engine running at full throttle, hold the loader control lever in the ROLLBACK position for 15 seconds.
B. Put the loader control lever in the NEUTRAL position for 15 seconds.
C. Repeat steps A and B until the temperature of the oil is 125 ° F (51 ° C) or the side of the reservoir is very warm.
3. See the illustration below. Use a pressure gauge with a capacity of at least 4000 psi (27 580 kPa, 276 bar). Connect the pressure gauge to the quick disconnect fitting at Test Port 1. The quick disconnect fitting is located inside the LH frame rail to the left of the engine.
4. With the engine running at full throttle, turn and hold the steering wheel all the way to the right or to the left and read the gauge. Make a record of the reading.
