■
Persons must NEVER enter the danger area while sawing is in progress.
■
Always keep the free wire lengths between the drive unit and object being cut as short as possible
(max. 3.5 m) and mount guide pulleys at the wire entry and exit points in order to reduce the risk of
whiplash in the event of wire breakage. The whiplash effect causes great acceleration of the sawing
wire, resulting in parts of the wire lashing out or flying off with great force.
■
Make sure there are no objects such as scaffolding etc. within the wire whiplash area. In the event of
wire breakage, the whiplashing end of the wire may be deflected in an unexpected direction by such
objects.
■
The danger area has a radius of at least twice the free length of wire that would be unleashed in the
event of wire breakage (shown in yellow) and also includes the areas in the extended axes of the direc-
tion in which the wire is running (shown in gray). The danger area cannot be limited unless suitable
means of protection are employed (protective walls, curtains or wire guards etc.). The protective
devices must be arranged and mounted in a way that stops the wire lashing out in the event of wire
breakage and reliably prevents objects or fragments flying off.
■
The operator is responsible for cordoning off the area. If necessary, safety personnel must be posted
to prevent access to a wide area around the workplace
■
When setting up and operating the saw system and when removing parts that have been cut away,
always ensure that no persons are below the area in which you are working. Falling objects could
cause serious injury.
■
Children must be instructed not to play with the machine.
■
The machine is not intended for use by children, by debilitated persons or those who have received
no instruction or training.
■
Before beginning work, check the working area (e.g. with a metal detector) to ensure that no con-
cealed electric cables or gas and water pipes are present
.
External metal parts of the machine may become live if, for example, an electric cable is damaged
inadvertently. This presents a serious risk of electric shock.
3.9
ALWAYS SWITCH OFF THE WIRE SAW BEFORE ADJUSTING THE WATER SUPPLY. Readjustment of the water sup-
ply nozzle at the single-pair pulley stand or at any other position while the saw is running, in order to bring it into
line with the diamond wire, is STRICTLY PROHIBITED.
3.10 The wire length adjusting pulley (DS-WSRP wire store) must always be fitted, even when not in use. The flexible
wire guard can then be fitted in accordance with the instructions.
