Adjusting
Attention:
Make sure that thepowersupply,air sources
and the oillevelin theoil cuparein accordance
with the requirements.
Initial Operation (Fig.01)
Note:
The four pedals must be kept at theoriginal
position.
lPress down thepedal (J)to turnthe turntable
clockwise;
lLift the pedal (J) to turn the turntable
counter-clockwise;
lPress down pedal (I) to movebead breaker;
release it to restore;
lPress down pedal (H) to move the jaws on the
turntable outward; pedal again to move them
inward;
lPress down pedal(G), thetilting columnwill tilt
backward. Pedal it again torestore the tilting
column upright.
lWhen the Rise/fall control leverrislifted, the
supplementary arm device will go up.
lWhen the control lever is lowered down, the
supplementary arm device will go down.
lWhen 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 ofthe
sliding mouse).
Clamping SystemoftheJaws(Fig.14)
lThe position of the jaw (Fig.15) onthe 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.
lWhen pedal Hon high, the piston rod will move
inward and pull the jaws moving inward untilthe
minimum. At this time the distance of two
opposite jaws is10”for inner rim and 13”for
outer rim.
lWhen pedal Hon 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”forinner rim
and 23”for outer rim.
lWhile the jaws in motion, press pedal Hlightly to
keep it atthe middle level,the jaws willstop in
response. Do thisfunctionflexible toget the
jaws anywhere between themaximum and
minimum for different wheels.
Fig. 14
Fig.15
lThe principle of the abovemotion can be
explained by thefollowing: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 backand forth and stop,
so do the clamping jaws.
Drivesystem
lThe gearing chain: The gearing chain in this
machine is made up of motor,pulley,worm
reducer, turntable and so on (Fig. 16).
Fig.16
lThe motor RPM is about 1400.The ratio of speed
is 200. The rotary directionis controlled by
pedal J.Press down the pedal to make the
turntable rotate clockwise. Release thepedal to
stop the turntable. Lift up the pedal Jwith foot,

the motor and theturntable will both turn
counter-clockwise.
lIf contrary to above, change the phase wireof
the motor.
lConnect the ground wire to ground.
lIn the operation, the turntable generally turns
clockwise, only when the operation is obstructed
occasionally, it needs to turn counter-clockwise.
BeadBreaker
lThe bead breaker isonthe rightsideof the
cabinet. As the procedure requires, press down
pedal (I) (Fig.17)o start the bead breaker cylinder,
the piston rod will pull the bead breaker moving
towards the cabinet,with magnitude around
14075N. Release pedal (I), thebead breaker
will retract.
lThe bead breakeris ableto swingwithin a
certain range. In casethe range ofswing is not
appropriate, adjust the nut (Fig.18)at the right
end of the piston rod.
lThe bead breaker arm is adjustable with two
ranges.According to the size of tyre, choose
range 1 or range 2. (Fig.19)

TiltingcolumnUnit
lThe tilting column is under the control of tilting
cylinder in the cabinet,sothat thecolumncan tilt
backward in orderto removethe tyrefrom the
turntable easily,and restore to upright position
(the working position).
lThe tilting cylinder is controlled by pedal G
When it is pressed, the tilting column tilts
backward; and whenit is pressed again, the
column restore to the upright position (Fig.20)
lIf tilting speedis too fastor tooslow,adjust the
throttles to change speed. If the speed istoo fast,
fasten the screw on throttle mouth. If too slow,
loose the screw.The 5-way valve has two
throttles(Fig.21, of which “a”is for tilting
backward while “b”is for back to upright position.

plates of theseatfor limiting thehorizontal
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
ensure bearingthe sameweight. Theside ends
of two bolts should be away 0.5—1mmfrom the
vertical plates of the tilting column.
