Initial Operation (Fig. 01)
Note:
The four pedals must be kept at the original
position.
l Press down the pedal (J) to turn the turntable
clockwise;
l Lift the pedal (J) to turn the turntable
counter-clockwise;
l Press down pedal (I) to move bead breaker;
release it to restore;
l Press down pedal (H) to move the jaws on the
turntable outward; pedal again to move them
inward;
l
Press down pedal (G), the tilting column will tilt
backward. Pedal it again to restore the tilting
column upright.
l When the Rise/fall control leverr is lifted, the
supplementary arm device will go up.
l
When the control lever is lowered down, the
supplementary arm device will go down.
l When the Inflation pedal U(Fig.01-1) is lightly
pressed, air will spout from the air hose
connected with the barometer. When the pedal is
pressed down to the lowest position, air will
quickly spout behind four jaws (the end of the
sliding mouse).
Clamping System of the Jaws(Fig.14)
l The position of the jaw (Fig.15) on the turntable
is controlled by the movement of the piston rod,
which in turn is controlled by pedal H. There
are three levels for pedal H.
l
When pedal H on high, the piston rod will move
inward and pull the jaws moving inward until the
minimum. At this time the distance of two
opposite jaws is 10
” for inner rim and 13 ” for
outer rim.
l When pedal H on low, the piston rod will move
outward and pull the jaws moving outward until
the maximum. At this time the distance
between two opposite jaws is 20
” for inner rim
and 23 ” for outer rim.
l While the jaws in motion, press pedal H lightly to
keep it at the middle level, the jaws will stop in
response. Do this function flexible to get the
jaws anywhere between the maximum and
minimum for different wheels.

l
The principle of the above motion can be
explained by the following: The three positions
on the cam control air reaching different holes on
the 5-way valve, so piston rod of clamping
cylinder is able to move back and forth and stop,
so do the clamping jaws.
Drive system
l The gearing chain: The gearing chain in this
machine is made up of motor, pulley, worm
reducer, turntable and so on (Fig. 16).
Fig.16
l The motor RPM is about 1400. The ratio of speed
is 200. The rotary direction is controlled by
pedal J . Press down the pedal to make the
turntable rotate clockwise. Release the pedal to
stop the turntable. Lift up the pedal J with foot,
