Hoses and connections

WARNING Whipping hydraulic hose
Hydraulic hoses under pressure can whip
uncontrollably if screws loosen or are loosened. A
whipping hydraulic hose can cause severe injuries.
Depressurize the hydraulic system before
►
loosening the connection of a hydraulic hose.
Tighten the nuts on the connections of the
►
hydraulic hoses to the required torque.
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.

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.

Pressure adjustment

To ensure that the accumulator and hammer are not
overloaded, a separate pressure relief valve should
be installed, see picture below. It is set at a value of
30 bar over the hammer s maximum operating
pressure. If the carrier s breaker circuit is already
equipped with a pressure limiting valve, no extra
valve is necessary.
