1. Before beginning the installation, thoroughly clean the vehicle to remove dirt and contaminants that might
get into the hydraulic circuit.
2. Park the vehicle on a clean, level floor with adequate clearance to work around.
3. Do not attempt to loosen any hydraulic fittings while the engine is running.
4. Allow the motor and the hydraulics to cool until it is no more than warm to the touch before proceeding.
5. Carefully trace the EF line from the prioritized pump to be sure there are no aftermarket components that
may be damaged by high pressure if they are upstream from the new electric/hydraulic steering valve.
6. Prior to loosening any hydraulic fittings, be sure to have the appropriate plugs and caps available in order
to limit loss of hydraulic fluid from the open fittings.
PREVENT HYDRAULIC SYSTEM CONTAMINATION. It is essential to thoroughly clean hydraulic
system fittings and hose connections prior to disconnecting or removing them. Use a spray
cleaner such as “Brake Clean” to prevent hydraulic system contamination. Note that o-rings used
on ORB and ORFF type fittings may be damaged by solvent cleaners such as “Brake Clean”. If a fitting is to
be cleaned internally, the o-ring should first be removed and cleaned with a fiberless cloth.
IMPORTANT
TO AVOID EXCESS LEAKAGE, DO NOT TURN THE STEERING WHEEL WHILE
THE FITTINGS ON THE MANUAL STEERING VALVE ARE DISCONNECTED.
WARNING: HOT, HIGH PRESSURE FLUID HAZARD. Hydraulic oil may be hot and under
extreme pressure. To prevent serious injury or death, relieve system pressure and allow the
system to cool before repairing or disconnecting. Wear proper hand and eye protection when
searching for leaks, using wood or cardboard instead of hands. Keep all hydraulic components in good repair.
WARNING: PINCH POINT HAZARD! To prevent serious injury or death, avoid unsafe practice
while manually operating hydraulic steering circuits. Keep others away and stay clear of
mechanical steering linkages.
