✅ Solution:

• Check if solenoid 11MY21 is energized.

• Inspect brake valve 7.2 for sticking.

• Test pilot valve 17 (should be 30 bar).

• Check spool port pressure (25–30 bar).

• Confirm pressure at shuttle valves (5, 6, 8, 9).

• Clean or replace solenoid, shuttle valve, motor, or brake valve as needed.

• Resolve any air locking issues

✅ Solution:

• Inspect solenoids 31MY21 & 31MY22.

• Check relays, limit switches, wiring, and SLI status.

• Make sure 4Mo (M2) spool operates at 30 bar.

• Eliminate air locking.

• Overhaul lamina brake or replace derrick motor/gearbox if needed

✅ Solution:

• Check solenoids 12MY21 & 12MY22 and corresponding relays.

• Eliminate air locking.

• Inspect spool operation with 6 bar pressure.

• Test lamina brake condition.

• Overhaul or replace aux. hoist motor (No. 10.1) and gearbox.

• Confirm proper functioning of SLI system.

• Ensure pilot pressure is adequate

✅ Solution:

• Check solenoids 11MY21 & 11MY22.

• Verify relay, limit switch, and wire continuity.

• Test M2 valve spool (4Mo) shift with 30 bar pilot pressure.

• Eliminate air locking in the pressure port.

• Overhaul jammed lamina brake or hydraulic motor if faulty.

• Check gearbox for damage; replace if needed.

• Confirm pilot pressure is present.

✅ Solution:

• Arrest any leakage in the system.

• Check non-return valves (No. 37, 46) in pilot circuit (Q5 & Q9 pumps).

• Clean and refit valves; replace if damaged.

• Inspect flow regulator (No. 21); set flow to 15 l/min.

• Check gauge No. 33 and replace if faulty.

• Verify Q5 pump flow (15–23 l/min) at different RPMs.

• Replace defective Q5 pump or coupling.

• Adjust pressure regulator valve (No. 28) to 30 bar; replace if damaged

Potential issues include:

• Lack of lubrication 
• Rollers too tight
• Broken roller pins  

Solution: Lubricate properly, check roller alignment, and replace damaged pins.
