USE OF THE QUICK COUPLERS
CONNECTION
Make sure that the contact surfaces of the couplers are clean and if necessary with a rag.
Position the male coupler towards the female one, centring them.
While pulling back the female knurled external bush press the male coupler against the female one.
Release the female bush and a “click” indicates that the proper connection is made.
IF A PROPER CONNECTION CANNOT BE MADE EVEN PRESSING THE COUPLERS WITH
STRENGTH, IT IS POSSIBLE THAT ONE OR BOTH COUPLERS ARE PRESSURIZED .
FOR MAKING THE CONNECTION IT WILL BE THEN NECESSARY TO TAKE AWAY PRESSURE BY
UNSCREWING THE COUPLERS FROM THEIR FITTINGS AND ALLOW SOME OIL DROPS TO COME
OUT.
DISCONNECTION
Pull the knurled bushing of the female coupler away from the male .
Pull the male away from female.
The male coupler will be released and a “click” will show the disconnection.
OTHER ADVICES
The connection/disconnection of the couplers must be done always WITHOUT OIL CIRCULATION –
WITHOUT PRESSURE.. the control valve lever must be in the OFF central position in the
connection/disconnection
Disconnect and connect the tools from hoses and power source, just after having set the lever of the
flow control valve in
OFF CENTRAL POSITION
.
The quick couplers must be dismounted from the power pack only with the engine
OFF
.
If you mount or dismount the quick couplers, use only the right wrenches. If improper tools are used
the coupler hexagon can be easily spoiled.
The quick couplers CANNOT BE REPAIRED. Discard immediately damaged or deformed couplers
and not force the connection if one coupler is damaged. In this case the damaged coupler will
immediately damage also the other good interface.
