column. Also, there are two bolts on the side
plates of the seat for limiting the horizontal
position of the tilting column. Before operation,
the two bolts on the base plate of the tilting
column should be on the same horizontal level to

vertical plates of the tilting column.
Horizontal Arm and Hexagonal
Column Clamping Unit
l As shown in the figure 22 use (air valve) locking
button J on the handle (k) to control movement of
the clamping cylinder. When thumbed down the
button, the external shells of clamping cylinders
(b and g) are pushed out. Their external shells
touch locking boards (c and h). The tilting of the
boards will lock the horizontal arm and the
hexagonal column.
Fig.22
l When the button is pressed out by index finger,
the clamping cylinder (b and g) will be drawn
back. The tilting boards (c and h) will relax to
loose the horizontal arm and the hexagonal
column. When it doesn
’ t work, nuts (e and i)
can be tightened or loosened for adjustment.
Supplementary Arm
l Figure 02-1 shows structure of the
supplementary arm that consists of such three
main function units as roller, press block and disk.
The horizontal column unit, swivel arm unit, disk
unit and sliding sleeve integrate them together
and can move up and down along the sliding
column under control of rise/fall control lever on
the control box. When the rise/fall control lever is
lifted, the supplementary arm moves up along
with the sliding sleeve. Contrarily, when the
rise/fall control lever is pressed down, the
supplementary arm moves down. If it causes
flutter when supplementary arm moves up and
down, adjust the four locking screws on the side.
