Diamond Products SK-B - Manual (Page 68)

Create sufficient free space for safe working. Mount the wire saw directly on or as close as possible to
the object to be cut, so that free wire lengths can be avoided or reduced to a minimum.
Block off the hazardous area (Fig. 1 / 2 / 3 No. 1) visibly so that no-one can enter the hazardous area
during sawing.
When working with wire saws there is a risk of the wire splitting, possibly triggering a whiplash effect
with the free length of wire. Such whiplash effects can cause serious physical injury. For this reason the
safety distance stipulated below must be maintained.
During sawing, the operator and any third persons must maintain a safety distance around the wire
saw equivalent to a radius of at least 2x the free wire length.
(See Fig. 1 / Direct mounting Fig. 2 / Ground-level cut Fig. 3)
The areas to the front and rear of the sawing operation and the area beneath it, together with any drilling
area, are to be secured so that persons cannot be injured or equipment damaged by falling parts or by
sawing slurry. Secure drilling cores and concrete blocks that have been cut free to prevent them from
falling.
Before sawing operations commence, the prescribed checks must always be carried out.
- Check the entire system, drive units, electric cables and hydraulic hoses prior to use for any damage
and to ensure that they function properly.
- Check wearing parts in particular, such as diamond wire drive pulleys, deflection pulleys, diamond
wire and connector.
- Check all the wire guards.
- Check that all components are correctly fitted and that all other conditions facilitating safe working of
the machine are fulfilled. Have any faults rectified by the HYDROSTRESS specialist or HYDROSTRESS
service department.
- Check all screws on the guard that could work loose due to vibrations.
Metal anchoring elements, size M12, should be used to anchor the universal and single roller brackets.
A secure anchoring that is suited to the substratum and will not come loose must be guaranteed.
In the case of inhomogeneous brickwork, we recommend drilling through holes using threaded M16
rods and adjusting nuts.
Only use a HYDROSTRESS tension spindle fixing point or anchoring screws of a minimum quality of
8.8 according to ISO.
NEVER work without wire guards (Fig. 1 No. 9, Fig. 2+3 No. 6)! These guards prevent segments and
connectors from flying off in an uncontrolled manner if the diamond wire breaks (Fig. 1 / 2 / 3 No. 7).
NEVER stand in the axis of alignment (Fig. 1 No. 3) of the running diamond wire (take note of the
hazardous wire alignment area, Fig. 1 No. 2).
Handling the saw system while sawing is in progress (e.g. repositioning water spray jets onto running
diamond wire) is prohibited. ALWAYS TURN THE WIRE SAW OFF FIRST!
Repairs to electrical and mechanical parts should only be undertaken by a qualified, authorized technician.
When the saw is not in use, or when moving it, checking the drive unit or during maintenance work,
disconnect the electric cable from the mains power. Ensure that the unit is switched off when changing
the diamond wire or changing the position of the wire pulleys. The EMERGENCY STOP switch must
also be activated.
