Observe all the applicable national and regional
regulations on securing loads.
Installation
Before installing the hydraulic breaker on the carrier
or operating it, read the operation manual and safety
instructions provided by the carrier manufacturer.
Follow all instructions.
The carrier must have the appropriate hydraulic
system for operation of the breaker.
If the carrier is too large for the hydraulic breaker it
may lead to broken working tools and increased
wear. See "Technical data" for choosing suitable
carrier.
The safety equipment in the hydraulic system must
be checked for quality (CE mark, etc.), suitability and
functionability by a professional or authorised
supervisor before use.
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.
► Depressurise 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: ORFS standard nipple. The nipple
dimensions can be found in the Spare parts list.
The quality of the hydraulic hoses must 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 coupling 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 end caps when dismounting.

are connected with an additional connection nipple,
another tightening torques must be used.
