5. Safety precautions
■
Make a careful note of any influence the immediate
surroundings may have on operations. Do not use the
hydraulic saw system in areas where there is a risk of
explosion or in close proximity to combustible materi-
als, fluids or gases. Flying sparks or electrostatic dis-
charge can lead to fires or explosions.
■
Do not cut materials which may produce toxic or
explosive dust or vapours when cut.
■
Do not cut easily combustible aluminium or magne-
sium alloys.
Safety precautions to be
observed when assembling, securing
and operating the wall saw
■
Use metal anchors (size M 12) for fastening DS-RF
rail supports and DS-RFP angular cutting plates. Secure
fastenings of a type suitable for the material being cut
must be installed, e.g. Hilti HKD-D, HSA-A, Hilti HIT, HEA
/ HAS anchors.
■
Use only ISO 8.8 grade fastening screws for the rail
supports.
■
An end stop must always be fitted at the end of the
rail to prevent unintentional advance beyond this point
(prevents saw coming off the end of the rail).
■
The blade guard must always be in place when the
saw is in use. NEVER stand in the direction of radial flight
of a running saw blade. Special precautions must be tak-
en to secure the danger area when special cutting appli-
cations are in progress.
■
Always operate the machine from the closed side of
the blade guard when corner cuts are made with the
blade guard in the partly open position. The operator
must take additional precautions (fit a cover, plank of
wood, boards etc.) where necessary.
■
Never attempt to connect or disconnect hydraulic
hoses while the hydraulic unit is running and while the
hoses are under pressure.

■
Handle the DS-RFP angular cutting plate carefully. There
is a risk of pinching your fingers.
■
It is essential that the prescribed checks are carried
out before beginning sawing (see section 5.5).
■
Unless special safety precautions are taken, the D-LP 32/
DS-TS 32 must NOT be operated in environments where
there is a risk of explosion.
■
The hydraulic unit and the operator with the remote
control unit should be positioned as far as possible out-
side the danger zone. The operator with the remote con-
trol unit should remain at a safe location while the saw
is in operation.
■
Use only adequately dimensioned fastening materi-
als to secure the saw (anchors, screws, etc.). Recom-
mendations can be found in our catalogues and bro-
chures.
■
Operate the saw only when the blade guard and rail-
end stops have been fitted and secured.
■
Observe the recommended cutting speeds and advance
pressures while sawing.
■
Protective gloves should be worn as the oil and parts
of the equipment can become very hot.
■
Wear the protective clothing and other items of pro-
tective equipment listed in section 5.1.
■
Before each cut, check that there is no play between
the saw head and the rail and that the eccentric rollers
are engaged.
■
When additional safety precautions are taken, over-
head sawing is also possible. In this case, the blade guard
must be equipped with a means of water drainage. Do
not stand beneath the saw.
Securing the objects being cut
and disposal of sawing slurry

Steel wedges and/or supports must be used to pre-
