²Caution should be taken
when separating the tyre
from rim. The bead breaker
shoe will move rapidly and
forcefully when the pedal is
depressed. Keep bodyand
materials away fromthe
work area.
²If the clampingcylinderis
open during clamping,
squeezing on hands canbe
resulted. Rememberto
keep hands away from the
inside of thetyre when
clamping.
²High voltage power!
Dangerous!
²This is where the
compressed air gunis
connected with the air pipe.
Connect the compressed air
gun with the air connector.
²The pressure of the
compressed airshouldnot
exceed 10 bar.
Description ofSafetySigns
²Toprevent accidents from
occurring, make sureto
keep hands andother body
parts away when fastening
the mount/demount heador
when the turntable is
running.
²Be careful when connecting
and disconnecting air
source. Bleedthe airinthe
cylinder completely when
maintaining the air pipes to
prevent accidents from
occurring.
²Don’tkeep hands or other
body parts between the
clamping jaw and clamping
rim.
²Pay attention tothe safety
regulations in the swinging
area of the tilting post to
avoid accidents from
happening.
²Before inflating check ifthe
clamping rim and the tyre
match each other,andif
they are in good condition.
Any negligencemay result
in fatal explosion. Similar
accident may occur if the

General Information
Usage
TWC-502RMB is used for demounting, mounting and
inflating tyres of small and mediumvehicles.
Mount/demount help device and quick-inflating device
features simple operation and high reliability.In addition, it
can also be agreathelp in car repair garage and tyre
dealers.
Features
lThe equipment can be used for different purposes of
demounting, mounting and inflating tyres.
lThe steel mount/demount is cast from excellent alloy
material with special shape and durable performance.
The supplied plastic mount/demount head with the
equipment ismade from special engineering plastic
that has enoughintensityand notdamagethe tyre
and rim.
lThe two clamping cylinder ensures accurate central
alignment, so that the wheels can be held tightly.
lPneumatically controlled tiltingsystemsaves the
effort and time of the operation.
lMoving up and down of the hexagonal column and
locking of thehorizontalarmis controlled byabutton,
which save operation time and make operation safe.
lHuman design of the mount/demount help greatly
reduces work-intension of the operator,making
tyre-mount and tyre-demount operations convenient
and easy.
lThe quick-inflatingdevicekeeps tyrebeadclose to
the rim tightly,avoiding over-long time inflation or
difficult inflation when the gun inflator is used for the
empty tyre.
lThe layout of the pedals gives convenience to the
operating personnel.
lThe bead breaker shoecan beadjustedto match
tyres with different widths.

Operation
Attention:
The use ofthismachine is reservedtospecially
trained and authorized personnel. 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 andthe oillevel in the oil cupare
in accordance with the requirements.
Principles
lToavoid damage when mounting and demounting
tyre, especially the alloy ones, use the tyre lever
offered by manufacturer.
lFor easier demounting and better protection of the
tyre and rim, lubricate the area between the rim and
tyre bead, where thebead breakershoe goes in,
with industrial lubricant or thick soap solution.
lCheck for damages (distortions, surface damages,
excessive runout, erosion or overall wear) before
demounting.
lPay special attention to rotary direction marked on
some flanges or tyres.
lFit the tyre on the rim of matched size.
lNever ignorethe mounting anddemounting
requirements of the special wheel.
lWhen inflating thetyre, make surethe pressure
increases in an even way.Pay attention to status of
the tyre bead.
Demounting Tyre
Preparing
lDeflate the tyre thoroughly.
lRemove all the foreignsubstance andweights from
the rim (Fig. 03).
Fig.03
Demounting
Attention:
Lubricate the bead with abrush dipped in soap
solution before theshoe touches the bead.
Otherwise the tyre bead willbe worn (Fig. 04).
Fig.04
lPlace the tyre betweenthe bead breaker shoe and
rubber pad and keep the shoe between the tyre
bead and rim, about 1cm to the bead(Fig. 05).
Depress pedal (I)(Fig. 06) to separate the tyre from
rim.
lRepeat the above steps on other part of the tyre to
get the tyre separated thoroughlyfrom the rim.
lPlace the wheel on the turntable. For the asymmetric
deep groove rim, keep the narrow rim upward.
lDepress pedal H(Fig.07) to the end to clamp the rim.

Note:
Different types ofclamping can be chosen in
accordance with different rims.
ØIn case of inward clamping, shrink the jaws
together,placethe wheelon the turntable and
depress pedal (H) to clamp.
ØIn case of outward clamping, enlargethe jaws
outward (2-3cm away from periphery of the rim)
and place the wheel on the turntable. Draw out
the curve arm. Aim the Location cone at the
central hole of the wheel(Fig.08), press down the
rise/fall control lever tokeep the rimclose to the
jaws, and depress pedal (H) to clamp it (Fig. 09).

Fig.09
lDraw out the roller-1and make it close to the tyre
bead. Press down therise/fall control leverto move
the roller-1 downward 3-5 cm, than turn the lock bar
to lock the slide rod .Depress thepedal J(Fig.10) to
turn the turntable clockwise. Atthe same time,
lubricate the tyre bead with lubricant by abrush (Fig
11).

Fig.11
lDepress pedal (G) (Fig.12) to restore the tilting
column to its working position (Fig.13).
lPress the hexagonal column and draw out the
horizontal arm to make the mount/demount head
touch the clamped rim. Push button (a) (Fig.13) on
the locking handleto clampthe hexagonal column
and horizontal arm. Atthis moment, theinner ring of
the head stays about 1～2mm from the rimto avoid
scratching (Fig.14).
