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 ventilated. Expo-
sure to dust at a poorly ventilated workplace may result
in damage to the health.
c)
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.
d)
In order to avoid injury and to prevent the diamond
blade becoming trapped or jammed, steel wedges and/or
supports must be used to prevent uncontrolled move-
ment of parts of the structure being cut.
e)
Ensure that adequately-sized supports are correct-
ly installed so that the remaining structure maintains
its stability after completion of the cutting work and
removal of the part cut away.
f)
Never loiter in the vicinity of loads suspended by
cranes.
g)
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.
h)
Wear personal protective equipment. Wear safety
shoes or boots, protective gloves, a hard hat, ear pro-
tection and eye protection.
2.1
i)
Wear respiratory protection if the work causes dust.
j)
Keep children and other persons away from the work-
ing area.
k)
Do not allow other persons to touch the machine or
the extension cord.
l)
Avoid unfavorable body positions. Make sure you
work from a safe stance and stay in balance at all times.
m)
To avoid presenting a tripping hazard, always ensure
that cables and hoses leading to the machine are laid
flat on the floor.
n)
Keep cables and hoses away from rotating parts.
o)
In cooperation with the site engineer or architect, ensu-
re 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 present a serious hazard
if damaged while the work is in progress. External metal
parts of the machine could become live if, for example,
an electric supply cable is damaged.
p)
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.
q)
Do not work from a ladder.
Safety measures at the danger areas
Safety measures must be implemented in the area whe-
re sawing is taking place to ensure that operators and
bystanders cannot be injured or property damaged by
debris that may fly off or fall down (broken-off diamond
segments, small stones, sawing slurry, etc.) while
sawing is in progress. Safety measures must also be
implemented in the area not directly visible to the ope-
rator, i.e. behind where sawing is taking place.
Persons must NEVER enter the danger area 10 feet (3
meters) – in all directions from the line of the cut to
be made – while the blade drive is switched on.
