16.2 Positioning of paper
A drill underlay (special cardboard)
is laid on the sliding table and a pa-
per stack on top of it in such a way
that it lays completely against the
back stop (23) The stack is then
centered by the two side stops (27)
The lever next to the right side stop
locks the position. The left side stop
can be hidden underneath the table
in order to position the paper diago-
nally on the table. The left side stop
becomes accessible again if the
right side stop is moved to it's outer
most position. In the starting posi-
tion the sliding table must be posi-
tioned that the stop set collar which
sits completely to the right on the
stop bar knocks against the stop of
lever (28). The right hand operates
the hand lever (28). The left hand
pushes the paper lightly and con-
tinuously against the side and back
stops during the drilling process.
