Operation
Note:
Do not operate the machine before having completing
training and qualified for operating the tyre changer.
Use appropriate equipment, tools and personal
protective equipment, such as eye-glasses, ear-plugs
and working boots, when operating the tyre changer.
Make sure that the power, air sources and the oil level
in the oil cup are in accordance with the
requirements.
Principles
zTo avoid damage when mounting and demounting
tyre, especially the alloy ones, use the special tyre
lever.
zFor easier demounting and better protection of the
tyre and rim, lubricate the area between the rim and
tyre bead, where the bead breaker shoe goes in,
with industrial lubricant or thick soap solution.
zCheck for damages (distortions, surface damages,
excessive runout, erosion or overall wear) before
demounting.
zPay special attention to rotary direction marked on
some flanges or tyres.
zWhen inflating the tyre, make sure the pressure
increases in an even way. Check the rim as often
as possible.
zFit the tyre on the rim of matched size.
zNever ignore the mounting and demounting
requirements of the special wheel.
Demounting Tyre
Preparing
zDeflate the tyre thoroughly.
zRemove all the foreign substance and weights from
therim(Fig.03).
Fig.03
Demounting
Note:
Lubricate the bead with a brush dipped in soap
solution before the shoe touches the bead.
Otherwise the tyre bead will be worn (Fig. 04).
Fig.04
zPlace the tyre between the bead breaker shoe and
rubber pad and keep the shoe between the bead
and rim, about 1cm to the bead (Fig. 05). Depress
pedal I (Fig. 06) to separate the tyre from rim.
zRepeat the above steps on other part of the tyre to
get the tyre separated thoroughly from the rim.

Fig.05
Fig.06
zPlace the wheel on the turntable. For the asymmetric
deep groove rim, keep the narrow rim upward.
zDepress pedal H (Fig.07) to the end to clamp the rim
Note: Different types of clamping can be chosen in
accordance with different rims.
Fig.07
Fig.08
¾In case of inward clamping, shrink the jaws
together, place the wheel on the turntable and
depress pedal H to clamp.
¾In case of outward clamping (Fig. 08), enlarge the
jaws outward, place the wheel on the turntable
and depress pedal H to clamp.
zPull back the swing arm and turn the handle of the
screw (12) to put the hexagonal column in working
position (Fig.09), and keep a distance of 1~2mm
from the mount/demount head (Fig.10), and then
lock the hexagonal column with locking handle.
Note:
The angle of the mount/demount head has been
adjusted by manufacturer according to standard rim
(15"). Re-adjustment may be necessary to prevent
scratching the tyre when the rim is extremely large or
small.
Fig.09
Fig.10
zLift the tyre bead onto the mount/ demount head with
tyre lever (Fig. 11). To make it easy, press the tyre
opposite to the mount/demount head. After settling it
down in the rim groove, depress Pedal J（Fig.12）
lightly to turn the turntable clockwise until the rim is
separated. To avoid damage to the tube when there
is one, it is advisable to place the air inflating valve
about 10cm (Fig.13) away from the mount/ demount
head.
Caution:
In case the demounting is hindered, stop the machine
immediately. Lift up the pedal J (Fig.12) to turn the
turntable counter-clockwise to clear away the
hindrance.

zIf there is tube in the tyre, remove it.
zLift the lower tyre bead after removing the tube from
the tyre so that the rim at the relative side enters the
groove(Fig.14). Depress pedal H (Fig.07) to loose
the jaw and take the rim off to complete the
demounting
Caution:
Keep hands and the rest of human body away from
the moving parts of the machine. Never wear necklace,
bracelet or loose clothes when operating the machine
as it may cause danger!
Mounting tyre
Note:
Check the size of tyre and rim to see if they match
each other.
zClamp the rim tightly in the same way as demounting
tyre.
zUse lubricant such as thick soap solution on the tyre
and the rim.
zPut the bead on the rim with the left side upward,
and pull back the mount/ demount head to the work
position (Fig.15)
Fig.15
zCheck the coordination of mount/demount head and
rim. Readjust if necessary.
zAdjust relative position between the tyre and the
mount/demount head to make the tyre bead cross
the mount/demount head. At the end of the
mount/demount head, the tyre bead should be
placed on the mount/demount head (Fig.16A). At the
beginning of the mount/demount head, the tyre bead
should be placed under the ball protuberance of the
mount/demount head (Fig.16B).
Fig.16
zPress down the central part of the tyre. Depress the
pedal J (Fig.12) to turn the turntable clockwise,

LAUNCH Tyre Changer (TWC-401NIC)

making the lower tyre bead fall into the rim groove
completely.
zIf a tube needs to be installed in the tyre, check first
for the possible damages. Round it onto the rim.
Make sure to keep the tube in the right position
throughout the mounting process.
zTo install the upper tyre bead, place the tyre well and
readjust position of the tyre bead (same as mount of
the lower tyre bead in Fig.17. Press down the tyre
opposite to the mount/demount head to the rim
groove (Fig.18)).
Fig.17
Fig.18
zDepress the pedal J (Fig.12) to turn the turntable
while keeping pressing on the tyre. When only
10~15cm is left, slow down to avoid damage of the
tyre bead. Stop the motor if there is any indication
for damage. Lift the pedal J and turn the turntable
counter-clockwise. Try again when the tyre is back
to the original shape.
Note:
It is not necessary to move the handle of the
screw every time if the size of rim matches the
tyre. Just move the swing arm.
In the process of operation, keep head and
hands away from the area between the tyre and
the swing arm to avoid injury.
Inflating tyre
Danger!!
Inflating can be highly dangerous. Take precautions
and pay close attention to the procedures. Check if
the compressed air is well connected before inflating.
Inflating procedures are shown in Fig.19. The machine is
equipped with a gauge to read the pressure in the tyre.
zLoose the wheel on the turntable.
zConnect the outlet of the gun to the air inflation
valve.
zSlowly press the switch on the inflating gun for
several times during inflation to make sure that the
reading on pressure gauge meets the
manufacturer’s specifications. The pressure
should not exceed 3.5 bar.
zIf the pressure exceeds the limit, press the button on
the gun inflator so that the pressure goes down to
what is required.
Caution: Danger of explosion!
The safety procedures should be closely followed.
Review and abide by the following instructions.
Otherwise serious injury or death can be resulted.
The manufacturer shall not be held responsible for
any possible accident when the safety procedures are
not followed.
Carefully check the dimensions of rim and
tyre to see if they match each other. Check
and make sure that the tyre is not worn or
damaged before inflation.
When a high pressure is required, remove the
tyre from the tyre changer and resume the
inflation in a special protective hood.
Be careful when inflating the tyre. Keep
hands and the rest of human body away from
tyre
