Inspect all springs for distortion. Roll manual valve on flat surface to check for bent condition. Clean and inspect all fluid passages, especially at check balls, valves and other areas where dirt and debris accumulate. Inspect all valve and plug bores for scores or obstructions. Inspect valves and plugs for burrs or scoring. All valves and plugs should move freely in bores. Valves and plugs should fall of their own weight into bores.
