5. Safety instructions
WARNING
Failure to observe the instructions listed below may
lead to potentially fatal injury and serious damage to
property or equipment.
Proper organization of the work area
a)
Approval must be obtained from the site engineer
or architect prior to beginning drilling or sawing work.
Drilling or sawing work on buildings and other struc-
tures may influence the statics of the structure, espe-
cially when steel reinforcing bars or load-bearing com-
ponents are cut through.
b)
Ensure that the workplace is well lit.
c)
Ensure that the workplace is well ventilated. Expo-
sure to dust at a poorly ventilated workplace may result
in damage to the health.
d)
Keep the workplace tidy. Objects which could cause
injury should be removed from the working area. Untidi-
ness at the workplace can lead to accidents.
e)
In order to avoid injury and to prevent the diamond
wire becoming trapped or jammed, steel wedges and/or
supports must be used to prevent uncontrolled move-
ment of parts of the structure being cut.
f)
Ensure that adequately-sized supports are correctly
installed so that the remaining structure maintains its
stability after completion of the cutting work and removal
of the part cut away.
g)
Never loiter in the vicinity of loads suspended by
cranes.
h)
The area of the cut or the opening created by the cut-
ting process must be safely and visibly cordoned off
in order to avoid the possibility of persons falling.
i)
Wear personal protective equipment. Wear safety
shoes or boots, protective gloves, a hard hat and eye
protection.
j)
Wear respiratory protection if the work causes dust.
k)
Dress properly for the work. Do not wear loose cloth-
ing or jewelry as it could be caught in moving parts.
Contain long hair.
5.1
l)
Keep children away. Keep other persons away from
the working area.
m)
Do not allow other persons to touch the machine
or the extension cord.
n)
Avoid unfavorable body positions. Make sure you
work from a safe stance and stay in balance at all times.
o)
To avoid presenting a tripping hazard, always ensure
that cables and hoses leading to the machine are laid
flat on the floor.
p)
Keep cables and hoses away from rotating parts.
q)
In cooperation with the site engineer or architect,
ensure that no gas, water, electricity or other supply
lines are located in the cutting area. Any supply pipes
or cables located close to the cutting area which could,
for example, be damaged by falling objects, must be
specially protected and, if necessary, switched off or
temporarily taken out of service.
r)
Ensure that the cooling water used is drained or
extracted in a suitably controlled manner. Water that is
allowed to drain away or spray around in an uncon-
trolled manner can lead to damage or accidents. The
fact that water could drain away into internal, hidden
cavities, e.g. in brickwork or masonry, must also be
taken into account.
s)
Do not work from a ladder.
Safety measures at the danger area
a)
Safety measures must be implemented in the area
where sawing is taking place so that operators and
bystanders cannot be injured or property damaged by
a broken sawing wire or debris that may fly off during
the sawing operation (wire connectors, diamond beads,
spacing springs, small stones, sawing slurry, etc.).
Safety measures must also be implemented in the area
not directly visible to the operator, i.e. behind where
sawing is taking place.
b)
Persons must NEVER enter the danger area while
sawing is in progress.
c)
Always keep the free wire lengths between the dri-
ve unit and object being cut as short as possible (max.
3.5 m) and mount guide pulleys at the wire entry and
