Operating during sawing
Driving in reverse direction while sawing will give a more uniform surface.
Driving in forward direction while sawing will allow more speed since it is less hard for the motor.
Carry out work in parallel tracks in such a way that the dust hose and electric cable do not become twisted.
The next figure shows the recommended working paths leading away from the dust collector.
Make sure that no vehicles, such as forklift trucks and other equipment run over the electric cable and the dust
hose.
The selection of the correct advancing speed of the machine is important for a good result. In the case that the
surface has different characteristics (e.g. different hardness or different coating thicknesses), a uniform result
can be achieved by varying the advancing speed during sawing.
The advancing speed depends on the material of the surface to be treated and the desired profiling.
The correct advancing speed can be found out by observing the treated surface and varying the speed during
the sawing process.
Slight profiling on concrete allows a higher speed than coarse profiling.
