HYDRAULIC INSTALLATION
HYDRAULIC QUICK DISCONNECTS
If hydraulic quick disconnects are used with the NPK Compactor/Driver, it is
recommended that the following precautions be followed:
1. Periodic inspection of both male and
female ends is recommended to
ensure the couplers are in good
working condition. Failure to inspect
couplers may result in pieces from a
damaged or failed coupler to be
injected into the hammer or parts of
the coupler returned to the machine.
2. Check for dirt, dust, and debris on
both the male (DXm) coupler and the
female (DXf) before coupling.
3. Be sure that the couplers are
completely seated together (38).
4. When replacing couplers, be sure that
couplers are replaced as a set, male
and female. Do not use one new end
and one used end.
