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
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 couplers (32) 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.
