Maintenance
Attention:
Only the specialized technician can perform the
maintenance. Before any maintenance, disconnect the
power and keep the plug within the sight of the
maintenance personnel. Shut off power and
compressed air, push the air valve switch to “Off”
position and depress pedal (H) for 3 or 4 times to
bleed the residual compressed air in the machine.
To keep the tyre changer in good condition and to prolong
the work life, it is necessary to do regular maintenance
according to the instructions on the user’s manual.
Otherwise, the normal operation and reliability of the
machine will be affected, or personal injury would be
caused.
l Keep the machine and working area clean, prevent
dust or foreign matter from entering the moving
parts.
l Keep the hexagonal column clean and dry (clean
with diesel as in Fig. 36).
l Keep the horizontal arm and horizontal pole clean
and lubricate them periodically so that it can move
expectably.
l Weekly clean the turntable, jaws, guideways (Fig.
37).
l Weekly clean and lubricate base pin.
l Weekly lubricate the faying surface between moving
parts and rubbing surface with lithium lubricant
(grease).
l Check the oil level in the oil cup regularly. If the oil
level does not reach the second line, fill SAE#20
(Fig.38).
l Regularly drain the condensed material in the air
cleaner.
l Regularly check and adjust the tension of the belt.
l Check all connecting parts and bolts regularly and
tighten them if necessary.
Fig.37
Fig.38
l Check and adjust the locking mechanism of
hexagonal column periodically to insure the
distance between hexagonal column and rim
(regularly 2~3 mm approximately) after the
hexagonal column is locked.
Attention:
Tighten the fixing screws (shown in Fig.39 as part A)
on the turntable after every 15 days of operation.
Fig.36
Fig.39
If the vertical clearance of the hexagonal column is
too much, adjust it according to the following steps:
l Shut off compressed air.
l Remove the protective hood of the hexagonal
column.
l Adjust the retaining nut of lead screw or the pushing
14
screw at the front of locking board by wrench.
l Turn on the compressed air and then check the
position after locking.
If the horizontal arm can not be moved smoothly or
LAUNCH Tyre Changer(TWC Series)
the clearance is too much after locking, do the
adjustment according to the following procedures:
l Open the protective cover of the tilting post.
l Adjust the M6 screws at both ends by wrench and
push the arm at the same time until it can be
moved smoothly. Then tighten the nut.
l Adjust the screw at middle by wrench and lock the
horizontal arm to see the change until the
clearance is satisfactory. Then tighten the nut.
Periodically clean the control valves for clamping
jaws and bead breaker to insure their normal
operation.
l Remove the side cover of the cabinet.
l Loosen the control valve muffler and air bleed
valve muffler, and clean them with compressed air.

l Finish measuring air pressure and inflation at the
same time, making operation quick and convenient.
l May preset values of inflation and deflation. When
the inflation gun is inserted into the tyre (non-empty
tyre), the device will automatically test and decide
inflation or deflation. When pressure of the tyre
reaches the set value, it automatically stop and warn
by the buzzer. When the tyre is empty and the
“RUN/STOP” key is pressed, the tyre is
automatically inflated to preset value.
l It can pause when the tyre is inflated or deflated.
l The device has swift function of air pressure unit and
can show both Bar and Psi values.
l Beautiful appearance and convenient installation.
with the device. If extension of the pipe is necessary,
total length must not exceed 20 meters. Otherwise,
working precision will decrease, or even the device
can not work normally.
l When the device starts to work, the inflation gun
should be deflated and not connected with the tyre.
Thus, the zero air pressure is got correctly to ensure
precision.
l Connection between the inflation gun and the tyre
must be reliable and no leakage.
l When the device is used, its power supply must be
far from the large power electrical applications.
Starting and stopping of these applications can
interfere the device accidentally. When interfere
caused by the momentary failure of the power supply
appears, sometimes abnormal errors will happen in
the computer of the device. The case can be
recovered to normal situation by that the inflation
gun head is moved and the power supply is off and
then on.

the inflator.
l There are no air supplies for these serial products.
Air pressure of additive air supply must be under
9.5Bar. If not so, a reducing valve must be fixed at
input air pipe to ensure that the air pressure of
entering the inflator is under 9.5Bar.
l Compressed air must be passed the oil and water
separator (air pressure regulator, gauge and
lubricator assembly) at first, and then is connected
into the inflator to avoid eroding internal parts of the
device.

Operations：
l Air pressure unit is showed in “bar (b)” in this device.
It can be changed to “psi (p)” unit by that “bar/psi”
key is pressed.
l Choose right pressure according to specifications of
the tyre. Press “+” or “—” key to set right pressure
values that satisfy requirements of specifications of
the tyre.
l After the pressure value is set, connect the clamping
head of the inflation gun with the tyre. If the tyre own
