▶
Do not start work until the drive unit and the pulley stands have been securely and
firmly secured to a solid sub-base. A toppling or dropped part can result in serious
damage or injury.
▶
Connect the electric power and compressed air supply only once the wire saw has
been set up completely.
▶
Do not start up the product before all covers have been correctly installed and closed.
▶
Entry into the danger zone (e.g. to adjust the pulleys or water supply, hammer in
wedges, etc.) is permissible only after the EMERGENCY STOP button or the ON/OFF
switch on the remote control unit has been pressed and the drive pulleys have come
to a standstill.
▶
Adhere to the permissible drive unit parameters and recommended guide values for
wire speed and advance pressure while sawing.
▶
Use only sawing wires that comply with the requirements of EN 13236. Use only one
wire connector per diamond-wire loop and connect only diamond wires of the same
type and diameter.
▶
The number of wire breakages experienced can be reduced considerably by using
high-quality wires and wire connectors and the appropriate crimping tools for fitting
connectors.
▶
The sawing wire can become hot, so do not touch it unless you are wearing protective
gloves.
▶
Use only fastening materials of adequate size (anchors, bolts, etc.) to fasten the pulley
stands for the wire saw and to secure the object being cut.
▶
If equipment such as scaffolding, platforms or ladders is used, check that this
equipment complies with regulations, that it is undamaged and set up in accordance
with regulations.
▶
Avoid awkward postures. Maintain firm footing and balance at all times.
▶
At all times while the saw is in operation, the operator must ensure that no persons
are present in the danger zone. This also applies to the area not immediately visible to
the operator, i.e. the area behind or below the object in which the cut is being made.
If necessary, a large area must be cordoned off or security personnel posted.
▶
Stay alert at all times. Keep the sawing process and the surroundings of the working
area under observation. Do not operate the machine if your full attention is not on the
job.
▶
Modifications to the saw system are prohibited. Changes to the ex-works settings of
the frequency converter parameters are prohibited.
2.5 Safety concept for working with wire saws
Operate the wire saw only when you and all other persons are as far as possible outside
all danger zones. By adopting additional measures (e.g. setting up cordons or posting
guards), make sure that no-one enters these danger zones while the equipment is in
operation. Danger zones extend also to the areas that are hard to see or cannot be seen
from in front (e.g. the rear of the structure to be cut).
Notes for safe working practice:
• Never enter the area underneath the work zone while the equipment is being set up
and while the wire saw is in operation. Falling parts can cause serious injuries.
• Invariably, keep a safe distance of at least 2 m away from all parts that move while the
equipment is in operation.
