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 big for the hydraulic breaker it may
lead to broken working tools and increased wear.
See "Technical data" for choosing suitable carrier.
The safety equipment of the hydraulic system must
be checked for quality (EC mark, etc.), suitability and
functionability by a professional/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.
► Depressurize the hydraulic system before
loosening the connection of a hydraulic hose.
Tighten the nuts on the connections of the
►
hydraulic hoses to required torque.
Type of nipple: Atlas Copco ORFS standard nipple.
The nipple dimensions can be found in spare part
lists.
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.

The 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 dirty faster. Check and follow
the carrier's instructions for changing oil and oil filter.
It is common to change the oil filter more frequent
when a hydraulic breaker is installed.
SB hydraulic breakers are equipped with an oil
drainage plug to drain all oil before dismounting. This
is to reduce the risk of spilling oil.
NOTICE! When the SB breaker 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.

Assembly

WARNING Falling breaker can cause injuries
Place the hydraulic breaker in a safe position
►
where it cannot fall over and cause damage.
