HYDRAULIC INSTALLATION
HYDRAULIC QUICK DISCONNECTS
If hydraulic quick disconnects are used with the NPK Hammer, it is recommended that
the following precautions be followed.
1. Periodic inspection of both male
(DXm) and female (DXf) 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 male and female couplers
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.
