main function units as roller,press block and disk.
The horizontal column unit, swivel armunit, disk
unit and sliding sleeve integrate them together
and can moveup and down alongthe sliding
column under controlof rise/fall control lever on
the control box.When therise/fall controllever is
lifted, the supplementary arm moves up along
with the sliding sleeve. Contrarily,when the
rise/fall controllever ispresseddown, the
supplementary arm moves down. If it causes
flutter when supplementary arm moves up and
down, adjust the four locking screws on the side.
