outside of the rim, rotating positioning
screw to fix hexangular rod.(fig N-3)
3) Move tire changer column to put
dismounting head (figN-2) on outside of
rim.
4) Keep pneumatic rod towards down until the presser press rubber tire several
mm(lower than rim),and then rotating the turntable clockwise, the presser(fig N-4)
rotates and separates the rubber tire
from rim.
5) Operator should lubricate the outside
rim during separation to dismount
easier.(fig O)
“! ”warning : Make sure hexangular
rod and arm are in correct position to avoid rim and rod damages and danger during
above operation.

11
hexangular positioning screw(fig N-3) , move hexangular rod from turntable to get
ready for dismounting.
7.3.2 Dismounting outside tire
1) Positioning dismounting head
“! warning : Position and move tire changer column only leave the column
unworked..Hexangular rod is only used during tire installment, keep it away from
working zone.
Following steps if stiff tire:
a. Move dismounting head (fig P-1) to
working position. If there is a sensor,
rotating turntable and put the sensor
in the middle of dismounting
head.(fig P)
“! ”warning : Position and move tire changer column only leave column
unworked.
b. Loosen locking part(fig P-2)
c. Move hexangular rod (fig P-3) near the dismounting head. Keep pneumatic valve
(fig D-10) towards down and press the
tire . Leave enough room to position
dismounting head and insert lever.
“! ”warning : Br careful and keep your
hands away from presser.

12
d. After positioning dismounting head , lock dismounting head and insert lever.(fig
Q-3)
2)Keep pneumatic valve (fig D-10) towards up, and rise hexangular rod(fig Q-1),and
then turn back. Rotating elbow (fig Q-2) until opposite the dismounting head.(fig
Q)
3)Keep pneumatic valve(fig D-10) towards down, lowing elbow and press tire to
inside edge, which move tire to top of the
dismounting head easier.(fig R)
4)Rise HF200 rotate from inside to the top,
and then rotate turntable, dismount tire.
