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 (32) 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
migrate into the hammer or parts of
the coupler returned to the
machine.
2. Check for dirt, dust, and debris on
both couplers before coupling.
3. Be sure that the couplers are
completely seated together (38) .
4. For most non-NPK couplers, be
sure that couplers are replaced as
a set, male and female. Do not
use one new end and one used
end.
