z Clean the couplings regularly
z Always switch off the drive unit and relieve
the pressure in the hoses before handling
the wall saw
z If the hoses cannot be connected easily,
they are under pressure
(Release pressure in the hose)

The following hose connections must be
established:
z Connect the hose couplings with the angle
pieces to the wall saw head
z Connect the straight hose couplings to the
drive unit
z Push the hose coupling onto its counterpart
until you hear it “click”
z Twist the locking ring of the coupling
Never connect or disconnect
hoses when the drive unit is
running.
If the unit is running or if the
hoses are under pressure, a
stationary saw blade can still
suddenly rotate and seriously
injure someone. It is therefore
essential to closely follow the
instructions below.
Connect together both ends of any hoses,
which are not used, so that they are kept
clean and are protected.
