Type of nipple: Chicago Pneumatic JIC standard
nipple. The nipple dimensions can be found in the
Spare parts list.
The quality of the hydraulic hoses should be 2SC
(according to EN 857) or better when connecting
the breaker to the carrier. If quick couplings are to
be used, we recommend using the "Flat Face" quick
coupling. This type is sturdy and easy to clean. The
quick couplings pressure class must agree with the
carrier's working pressure.
Always clean the quick couplings before mounting
or dismounting. Always plug hoses and hose nipples
with tight and clean plugs when dismounting.

NOTICE The tightening torques in the table above
are valid when the pressure and return hose are
mounted directly on the hydraulic breaker's
connection nipple. If the pressure and return hose
are connected with an additional connection nipple,
another tightening torques must be used.
Hydraulic oil
Normally the type of hydraulic oil the carrier is using
also works for the hydraulic breaker. When a
hydraulic breaker is connected to the carrier, the
hydraulic oil will get contaminated faster. Check and
follow the carrier's instructions for changing oil and
oil filter.
It is common to change the oil filter more frequently
when a hydraulic breaker is installed.
NOTICE When the machine is delivered it contains
some mineral based hydraulic oil. Before connecting
to the carrier's hydraulic system, check which type
of hydraulic oil the carrier is using. Mixing different
types of hydraulic oil may destroy the lubrication
quality which can lead to machine damage.
In order to protect the environment we recommend
the use of biologically degradable hydraulic oil.
