Introduction
CAUTION: The ACE hydraulic system is
extremely sensitive to the ingress of dirt or
debris. The smallest amount could render the
system unserviceable. It is imperative that the
following precautions are taken.
l
ACE components are thoroughly cleaned
externally before work commences;
l
all opened pipe and module ports are
capped immediately;
l
all fluid is stored in and administered
through clean containers.
Remove
1. To avoid any possibility of swarf ingress,
2. Raise front of vehicle.
WARNING: Do not work on or under a
vehicle supported only by a jack. Always
support the vehicle on safety stands.
