--- | --- | ---
Hydraulic fluid accumulated on or leaking from hydraulic fittings. System will neither build nor hold pressure. | Fitting or adaptors are loose. | Tighten to torque values stated in assembly and recycling instructions.
Cannot connect hydraulic fittings. | Hydraulic nuts contain small amount of residual hydraulic pressure. | Slowly loosen fittings on hydraulic nut and/or hose to release residual pressure.
Fittings are damaged or worn. | Replace fittings.
Hydraulic fluid leaking from piston. System will not build pressure. | Hydraulic seals are worn or damaged. | Replace hydraulic seals.
Hydraulic nut difficult to screw onto bolt. Snagging or locking. | Damage on hydraulic nut or bolt. | Examine internal and external screwthreads for signs of damage or foreign particles.
