Abrading
You hold the pencil in your hand like a stylus. One finger must be placed at the top end of
the flat recess. You then apply light finger pressure to initiate the abrasion process.
8.4
Regulating the Abrasive
The pressure regulator at the rear of the instrument is set at the factory to 6 bar. This
setting must
not
be changed. Adjustment of the abrasive pressure is done
only
using the
black knobs at the top. You adjust the pressure by pulling the knob out and turning it to the
left
(
to reduce the pressure
) or to the
right
(
to increase the pressure
). You
then push the knob in again. The set pressure can be read on the pressure gauge.
Changing the pressure varies the abrasive feed velocity and the amount of abrasive used.
8.5
Cleaning Nozzles
The instrument is fitted with a compressed-air nozzle for cleaning the inner area and the
workpiece. You operate it by lightly bending the front section of the rubber pencil.
