3. T E C H N I C A L D E S C R I P T I O N
Your W S 75 is a full electrical wall saw which is only to be used for cutting masonry, stone and concrete
in industrial usage by trained personnel.
W ater is absolutely required for cooling the motor and for cooling and for cleaning the saw blade.
The diamond saw blade consists of a prestressed metal disk which is at its circuit fixed with segments made
of a sintered mixture of diamond grains and metal powder.
The sawing process is introduced by dipping the saw blade into the material, which is to be cutted. By
switching the feed direction over, the sawing support moves now along the guide-way to a desired point on
which is once more dipped in, in order to switch over to longitudinal direction for continuing the sawing
process.

3.2 Design
The complete sawing unit consists of the sawing support [1] - with rotating swivelling arm [2], which is
responsible for the adjusting movement in cross direction - the detachable saw motor [3] and the two Feed
motors for the dipping- [4] and longitudinal feed [5]. The saw blade [7] is fixed on the working spindle [6] of
the swivelling arm.
On normal sawing works the saw blade is in doing so fixed on the plate flange [8] which is screwed onto
the working spindle with a hexagon head screw [9] M12x25 10.9.
On works in which the saw blade is being guided almost flush along the wall the saw blade is to be fixed
with six hexagon head screws [10] M8x10 on the sawing flange [11].
The complete sawing support is assembled movable on the guide-way [15] with two locking levers [12] over
eccentric axis [13] and pivot bearing [14].
