zBefore using, air source must be turned on first, and then depress on sliding clamp control pedal to makesliding clamp
to retract for several times, do not power on turntable until the oil-mist separator begins to generate oil, otherwise it
could easily tear the rubber gasket of the rotary valve and cause trouble.
zWhen the machine has error during running, power should be cut off first, and then repair the fault.
zMounting and demounting requirements on special tires from the manufacturer should be paid attentionin any case.
zDuring operation, legs should not be put between pressure pedal and rubber stop so as to avoid personal injuries
caused by stepping on the wrong pedal.
zThe positions of demounting head and rim should be tightened after they are adjusted. And hand wheel should be
screwed tightly onto the cross arm to prevent damages to themachine and tire and personal injuries during operation.
zWhen the demounting head is placed in working position, hands should not be put on the tires to avoid personal injury.
zDuring clamping the rims, hands should not be put between tire and jaw to avoid personal injury.
zWhile approaching the tire, jawshould be closed to avoid personal injury.
zWhen the machine is running, the staff should be concentrated on it.
Pressure settings: As the machine works properly with pressure of 8-10bar, the coherent source pressure should be more
than 7bar.
Demounting head settings: When the machine is delivered, the demounting head is calibrated with standard 13" rim. If
there are exceptionally large or small rims, simply loosen the two column ends on the demounting head and the bolt at the
bottom of the hexagonal shaft, then rotate the demounting head, finally tighten the screw when curvature of the demounting
head can basically meet therim.
Oil volume settings: oil volume of atomized lubricator is calibrated when delivery. If the oil feeding speed is too fast or too
slow, adjust the needle of atomized lubricator with a screwdriver, and then depress the splitter control panel for 5–6 times till
a drop of oil dropped from lubricator. Always check the oil level in the cup, replenish with # 30 machine oil in time when
lacked.
2.1 Instructions on pedal working conditions
zInflating control pedal “ ”: There are 2 ranges: range 1 and range 2. Range 1 is located at the middle while range
2 is at the bottom. Range 1 is used for inflating tires with inner tubes and easily inflated vacuum tires, while range 2 is
used for inflating special vacuum tires.
zClamping pedal“ ”: There are 2 ranges: range1 at top and range 2 at bottom.
zSplitting control pedal“ ”: There are 2 ranges: low range and initial range.The pedal mustbe depressed and hold
to ensure it at low range; if the pedal is released, it will go back to initial range. Low range is for bead breaking action,
while initial range is for release action.
zTurntable control pedal “ ”: There are 3 ranges: low range, initial range and high range. The operation method

is the same with splitter pedal. Depress and hold the pedal, it is at low range; push up and hold the pedal, it is at high
range; release the pedal, it is at initial range. Low range is for clockwise rotation of turntable, high range is for
counterclockwise rotation of turntable, and initial rangeis for motionless turntable.
2.2 Splitting
Warn: If splitting is blocked, vehicle must be stopped immediately, and push up the turntable rotating control pedal
so that the turntable will rotate counterclockwise to eliminate resistance, otherwise capacitor and motor may be
damaged.
Preparation work:
zDeflate the air in the tire completely.
zRemove the sundries and balance block on the wheel to avoid accident, as
shown in figure 2-1.
zEffective lubricants (such as concentrated soapy water) should be used to
lubricate the rims so as to avoiddamages to the tire during operation.
Warn: Special tools should be used to remove the balance block to avoid
damagestorim. Figure 2-1
Operating steps:
1. Place the wheel between the splitter and rubber stop, place splitter between wheel edge and rim, then depress on the
splitting pedal to split the rim from the bead, as shown in figure 2-2.
Note: Before splitting, brush the concentrated soapy water in the container onto the bead for lubrication, as shown in figure
2-3
Figure 2-2 Figure 2-3
2. Perform repeated operations as above in other partsof the tire to split rim completely from bead.
3. Place the tire with loose edge on the sliding jaw to clamp the tire, then depress the clamping pedal to hold the tire (for
unsymmetrical rims with deep slots, the narrow rim should be placed upward.)
Note: Different clamping methods can be chosen according to different rims.

¾If to choose internally locking, draw back the jaw first, then place wheel on the turntable, finally depress clamping
cylinder pedal “ ” to clamp the rim.
¾If to choose externally locking (as shown in figure 2-4), stretch out the
jaw first, then place the wheel on the turntable to allow the two jaws inside to
clamp on the rims, hold the proximal side of tire by hands, depress clamping
cylinder pedal “ ” to place pedal at low range, jaws begin to tighten.
Observe the relativepositions of thetwo proximal jaws to rims, when theyare
close to the rim, lower downthe proximal side, jaws will clamp the rimtightly.
Figure 2-4
4. Adjust the demounting head,place it on the working position at upper rim, screw lateralrocker positioning hand wheel (12
as shown in figure 1,), lock the hexagon rod (①and ②as shown in figure 2-5). To avoid scratches in rim, place the
demounting head with a distance of about2mm from the upper rim side and edges, and then tighten the demounting head,
as shown in figure 2-6.
Figure2-5 Figure2-6
Note:
1. Due to prolonged use of rims, it is difficult to ensure roundness and parallelism. When the demounting head is in the
working position, find the maximum point of the rim and the highest point of roundness first. Then fix the demounting head
according to these two pointsto avoid scratching rims while demounting the wheels.
2 The positions of demounting head and rim should be tightened after they are adjusted. And hand wheel should be
screwed tightly onto the cross arm to prevent damages to themachine and tire and personal injuries during operation.
5. When stepping on the turntable pedal, move down pneumatic control tire changer hook till the hook extends into the
inner edge of the bead disengaged and provoke it (as shown in Figure 2-7), point step on turntable rotating pedal, so
turntable rotates clockwise till all the bead is taken out (Figure 2-8),

2.4 Inflating
The machine is equipped with a universal inflating gun, convenient and flexible. Equipped with a pressure meter, the
pressure in the tank can be observed at any time to ensure that sufficient gas can be provided when needed for less
inflatable vacuum tires.
Note:
Operation regulations should be strictly followed during tire inflating, gas circuit connection must be confirmed before
inflating.
During inflating, hands shouldnot be putbetween rim and tire to avoid personal injuries.
During inflating, tire pressure should be increased uniformly, and the state of the bead shouldbe paid attention to.
During fast inflating, goggles should be worn toavoid debris falling into eyes.
Steps:
1. Connect the inflating gun connector to tire valve.
2. Inflating methods for tireswith inner tubes or easily inflatablevacuum tires:
Depress the inflating pedal to range 1, after inflating for a certain time, release the pedal, make sure the pressure
displayed on the meter within the range indicated by tire manufacturer. If it is out of range, press discharge button (as
shown 16 in figure 1) to release excessive gas.
3. Fast inflating methods:
For direct inflating with inflating gun, gas may leak from the bead, and bead cannot be placed against rim tightly. The
correct way is to push up tire so that bead can be tightly placed against rim first, then while inflating with the gun,
depress fast inflating pedal to range 2 for assistant inflation, so that large amount of gas can be inflated into the tire
quickly, then put bead closely against the rim, switch back to normal inflation mode. Make sure the pressure displayed
on the meter within the range indicated by tiremanufacturer.
Note:
¾The operator must be concentrated during tire inflation, hands and body should be kept away from the tire to avoid
personal injuries.
¾Before inflating, tire must be checked for damages, and pressure in the tire cannot be more than 3.5bar, as incorrect
tire pressure will influence tire lifetime, vehicledriving safety and operation stability.
