Replace coil. HV2 needle valve closed. Open valve. Solenoid spool may be stuck or centering spring broken. Free spool or replace spring. Solenoid may be mechanically actuated by inserting a piece of 3/16" rod against armature pin and pushing spool to opposite end. Push “A” side to confirm unload capability. If valve works, problem is electrical. Solenoid valve piston hung in bore or bolt loose. Check piston or tighten bolt. YY1 solenoid coil burned out. Replace coil. Check valve in solenoid valve piston bad. Replace or repair. Dirt inside solenoid valve preventing valve from operating both ways. Clean valve. Solenoid may be mechanical ly actuated by inserting a piece of 3/16" rod against armature pin and pushing spool to opposite end. Push YY1 valve to confirm unload capability. If valve works, problem is electrical. Slipper seals worn out or damaged. Replace. Check valve in slide valve piston sticking. Remove and clean check valve. YY2 solenoid coil burned out. Replace coil. Dirt inside solenoid valve preventing valve from operating both ways. Clean valve. Solenoid may be mechanically actuated by inserting a piece of 3/16" rod against armature pin and pushing spool to opposite end. If valve works, the problem is electrical. Solenoid coil burned out. Replace coils. Solenoid valve sticking. Replace valve. Slipper seals worn out or damaged. Unloader spindle or slide valve jammed. Slide stop indicator rod jammed.
