.2.1 Coupling
The unit is equipped with different quick-action couplings, i.e. "male" and "female".
For Twin-line tools, never connect or
disconnect the quick-action coupling when
the pump relief valve is set to “PRESSURE”/
“OPERATION”. Set the pump relief valve to
its "NEUTRAL" position before coupling or
uncoupling hoses and/or tools.
To couple the hoses using the flat face coupler:
1.
Remove the dust caps from both the male and female couplers.
2.
Insert the male coupler into the female coupler and push.
3.
The coupler’s locking ring (A) will move forward to show the coupler is locked.
4.
Check to make sure the connection is made by pulling on the two couplers.
To uncouple the hoses using the flat face coupler:
1.
Push the hose coupler gently forward into the tool/pump coupler.
2.
Turn the locking ring (A) of the coupler ¼ turn counterclockwise when holding it
in your hand pointing away from you (direction of large arrow on coupler)
and
pull back on the locking ring (direction of small arrow on coupler). l
3.
Remove the male coupler from the female coupler if it has not released
completely.
4.
Make sure you put the dust caps back onto the couplers when not in use. This is
an important step to keep dirt and foreign objects from getting into the coupler.

Core™ female coupler
Clean the female coupler by removing any dirt, oil, etc. with a clean dry rag. To ensure the automatic
locking capability of the coupler, the couplers and dust caps should be checked periodically and
cleaned by following the simple steps below:
1.
Rinse the coupler and dust cap with lukewarm water and a soft soap solution.
2.
When the coupling is dry and free from water, lubricate the flat end of the coupling (B) with
Holmatro recommended hydraulic oil or by spraying WD-40 onto the end.
3.
Lubricate the locking sleeve by spraying WD-40 carefully in the area (C) between the back
part and the locking sleeve.
4.
Connect the nipple into the coupling and see if the locking sleeve easily turns itself to the lock
position. Check by pulling the locking sleeve straight back. The nipple should not disconnect.
5.
To disconnect the nipple, turn the locking sleeve and pull it backward.
6.
Repeat steps 4 and 5 a few times to assist internal lubrication of the locking sleeve.
