(2) Signal pressure tap
Install a 0 to 40000 kPa (0 to 5800 psi) pressure gauge (1) onto signal pressure tap (2) .
Start the engine. Run the engine at high idle.
Warm the oil to a minimum temperature of 60°C (140°F). At least two segments should be visible on the bargraph for hydraulic oil temperature.

(1) Pressure gauge (3) Needle valve (4) Hose assembly
Slowly close needle valve (3) on hose assembly (4). As needle valve (3) is closed, the pressure on pressure gauge (1) will increase.
At approximately 17240 1380 kPa (2500 200 psi), the pressure should immediately drop to zero.
This will occur as the control lever is kicked out of the detent for the RAISE position.
If the detent kickout pressure is not correct, the detent must be adjusted.
If an adjustment is made, repeat Steps 1 through 8.
Repeat Steps 1 through 9 for all the implement control valves.Use the following procedure in order to adjust the detent kickout pressure.
