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 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.
In order to protect the environment we recommend
the use of biologically degradable hydraulic oil.
Viscosity
Viscosity (permitted) 15-100 cSt
NOTICE Always use clean oil and filling
equipment.
Assembly
Circulate the hydraulic oil before connecting the
hydraulic breaker. This is to make sure that the
hydraulic oil is clean. Use the same routine when
changing the hydraulic oil hose. For further
information see section "Hydraulic oil".
1. Connect the pressure and return hoses.
2. Run the hydraulic oil through the carrier's oil
filter for approximately 3 minutes to make sure
that the hoses are clean.
WARNING Falling breaker can cause
injuries
►
Place the breaker in a safe position where it
can not fall over and cause damage.
Preparation
1. Place the breaker in a position where it is easy
and safe to mount the adapter plate.
NOTICE Mount the breaker so that the
accumulator faces the operator's cabin, to
reduce the risk of accumulator damage.
Mounting the adapter plate
1. Place the adapter plate on the hydraulic
breaker.
2. Place NYLOK BLUE PATCH™ (Known as
TUF-LOK
®
in Europe) screws through all bore
holes and fit nuts to the screws.
