3.3Trimming 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.
3.4Making 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.
