5. Safety precautions
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
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.
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, ear pro-
tection and eye protection.
j)
Wear respiratory protection if the work causes dust.
5.1
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.
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, 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.
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.
t) The machine is not intended for use by children, by
debilitated persons or those who have received no
instruction or training.
u) Children must be instructed not to play with the
machine.
v)
Dust from material such as paint containing lead, some
wood species, minerals and metal may be harmful.
Contact with or inhalation of the dust may cause aller-
gic reactions and/or respiratory diseases to the opera-
tor or bystanders.
Certain kinds of dust are classified as carcinogenic such
as oak and beech dust especially in conjunction with
additives for wood conditioning (chromate, wood pre-
