3.3 Trimming the object surface
Turn on the water tap and adjust the water flow with
the valve (3.4). Align the nozzle (3.1 ) so that the water
jet lands on the edge of the saw blade. Turn on the
motor with the switch (6.1). Unclamp the object by pull-
ing the stop pin (2.2).
To save time, the speed of the object feed can be in-
creased while the object is guided towards the edge
of the blade. To do this, turn the knurled knob (7.1) clock-
wise.
The object must not meet the saw blade at
maximum speed. Shortly before contact is
made, turn the knurled knob (7.1) back to the
speed necessary for sawing.
The figures engraved on the knurled knob (7.1) are not
absolute speed values, but only guidelines to enable
repeat settings.
The most favorable feed rate must be determined for
each individual object. As a general rule, however, the
following applies: the lower the speed, the less the
forces coming to bear on object and saw blade, i. e.
the gentler the sawing process will be.
3.4 Making the section
After the object has passed through the saw, turn the
object arm (2.4) back as far as it will go. It clicks into
place audibly. Press the switch (6.1) to turn off the
motor. Remove the section from the blade.
