Clean Work Conditions.
If it is necessary to disassemble any of the component parts, make sure that a clean work bench or table is used (a piece
of wrapping paper makes an excellent clean disposable top).
Outside dirt should be cleaned off before disconnecting hoses. Port holes should be plugged immediately after
disconnecting hoses and before removing from the vehicle.
Finish cleaning off outside dirt before placing on work bench--especially the pump, valve, cylinder.
Parts should be cleaned in clear, clean solvent and blown dry with clean air. Keep each part separate to avoid nicks, burrs.
Avoid wiping valve and pump parts with cloth since lint may actually cause the sticking of closely fitted parts.
NEVER STEAM CLEAN HYDRAULIC STEERING ASSEMBLIES.
Do not force or abuse closely fitted parts--damage is probable.
