▶
Ensure that the method of securing the track guiding system to the workpiece
is capable of holding and restraining the machine during use. If the workpiece
is weak or porous, the anchor(s) can pull out, causing the track guiding system to
release from the workpiece.
▶
If the diamond wheel becomes jammed, stop applying feed force and turn off
the tool. Investigate and take corrective action to eliminate the cause of the
diamond wheel jamming. Attempting to continue operation with a stalled diamond
wheel can lead to loss of control or damage to the wall saw.
▶
Before starting, make sure that the AC supply voltage, AC supply frequency and fuse
rating correspond to the specification given on the type identification plate.
▶
Check the machine’s electric supply cable at regular intervals and have it replaced by
a qualified electrical specialist if found to be damaged.
▶
Check extension cords at regular intervals and replace them if found to be damaged.
▶
If the electric supply cable to the saw is damaged while working, do not touch the
supply cable or the saw. Switch the wall saw off at the on/off switch or press the
EMERGENCY STOP button and unplug the supply cord from the power outlet.
▶
Use only extension cables of a type approved for the application and with conductors
of adequate gauge.
▶
Do not work with rolled-up extension cables. A rolled-up cable may cause a drop in
power and may result in the cable overheating.
▶
Disconnect the power cable before beginning cleaning and maintenance work or in
the event of an interruption between periods of operation.
▶
Drilling and sawing work on buildings and other structures may influence the statics of
the structure, especially when steel reinforcing bars and/or load-bearing components
are cut through. Approval must always be obtained from the site engineer or site
management before beginning drilling and sawing work.
▶
Make sure that the workplace is adequately ventilated. Exposure to dust at a poorly
ventilated workplace may present a health risk.
▶
Install suitable supports to ensure that the part cut out does not move. Blocks slipping
or falling when cut free could cause serious injury and/or damage.
▶
Install suitable supports to ensure that the structure retains its stability while cutting
work is in progress and also after removal of the part cut away.
▶
In cooperation with the site engineer or architect, check to ensure that no gas, water,
electricity or other supply lines are located in the cutting area. Supply lines of these
kinds present a serious risk of accident if damaged during the course of the work.
External metal parts of the machine could become live if, for example, an electric
supply cable is damaged.
▶
Avoid skin contact with drilling and sawing slurry. In the event of contact with the
eyes, rinse immediately with clean water and consult a doctor if necessary.
▶
Dust produced by grinding, sanding, cutting and drilling can contain dangerous
chemicals. Some examples are: lead or lead-based paints; brick, concrete and other
masonry products, natural stone and other products containing silicates; certain types
of wood, such as oak, beech and chemically treated wood; asbestos or materials
that contain asbestos. Determine the exposure of the operator and bystanders by
means of the hazard classification of the materials to be worked. Implement the
necessary measures to restrict exposure to a safe level, for example by the use of
a dust collection system or by the wearing of suitable respiratory protection. The
general measures for reducing exposure include:
▶
working in an area that is well ventilated,
▶
avoidance of prolonged contact with dust,
