5.7 Cooling water supply
At a cooling-water temperature of 25 °C, a flow rate of at least 2 l/min is required to cool
the saw head.
The power of the wall saw will be reduced in the event of inadequate cooling. If this is
not sufficient, the wall saw’s automatic cut-out will be activated.
▶
Use only clean cooling water.
▶
Do not use salt water, i.e. sea water.
▶
Where pressure in the water supply line is low, a non-return valve should be fitted in
order to prevent dirty water finding its way into the water supply.
▶
Use a pressure reduction valve if the supply line pressure is greater than 6 bar.
6 Assembling the saw system
6.1 Installing the anchors for the track supports
WARNING
Inadequate fastening presents a hazard! A basic prerequisite for safe and efficient use
of the saw system is that it must be secured using a means of fastening suitable for the
applicable material and of adequate dimensions.
▶
Use a fastening system suitable for the material on which you are working and observe
the fastening system manufacturer’s instructions.
▶
For fastening on uncracked concrete use HKD-D M12 flush anchors or anchors of
an equivalent type with a minimum tensile loading capacity of 8.5 kN. Note that the
HKD–D M12 flush anchor is not suitable for use in masonry, man-made or natural
stone and similar materials.
▶
Please contact Hilti Technical Service if you have any questions about secure
fastening.
The following instructions apply to use of the HKD–D M12 flush anchor. If you use
a different type of anchor, please follow the anchor manufacturer’s instructions.
1. Mark the positions where the anchor holes are to be drilled. Attention must be paid
to the instructions given in the “Planning” section regarding the position of the anchor
holes. → page 19
2. Drill the anchor holes.
3. Remove the drilling dust from the anchor holes.
4. Insert the anchors in the holes and use the setting tool to expand the anchors.
5. Screw the fastening bolts into the anchors by hand, to the full depth of each anchor,
and then unscrew the bolts one complete revolution.
