If the pressure on the gauge is not 0 kPa(0 psi), loosen (turn counterclockwise) sleeve(12) until the pressure is 0 kPa (0 psi).Tighten (turn clockwise) sleeve (12) until thepressure on the gauge is 300 ± 50 kPa (43 ± 7psi).Loosen (turn counterclockwise) sleeve (12) oneturn. The pressure on the gauge will go to 0 kPa(0 psi). Tighten its jam nut to 30 ± 15 N.m(22± 11 lb. ft.).Stop the engine. Remove the pressure in the pilotsystem and remove the test equipment.Connect hose (6) to the pilot valve.Dump Stem Adjustment14. Disconnect hose (7).15.
