nical feature, technical parameter, characteristic
and safe grade of the tire. The related information
is marked on the side wall of the tire.
Note
$Before mount the tire, please change the core of
the nozzle to be the nozzle of tubeless tire.
Note
$Confirm whether the related parameter of the tire
matches the parameter of the rim or not. And also
make sure the rim is not deformed and the center
hole not damaged. While you should also secure
that the surface of the rim without the phenome-
non of rusty and broken and there is not any bur
at the nozzle.
$Confirm the tire is under perfect condition and

3. Position the tool head
$Step down the pedal 7-1 to move the tool head to
the original work position.
Note: If you do not change the rim, the tool head will
automatically back to the correct working position.
4. Mount the bottom bead
$Position the bottom bead at the bottom end of
the head of the tool head, while at the top end of
the tail of the tool head.
$Use your hand to slightly press the tire to lead the
tire into the groove of the rim.
$Rotate the turntable clockwise to mount bottom
bead.
5. Mount the upper bead
$Position the upper bead at the bottom end of the
head of the tool head, while at the top end of the
tail of the tool head.
$Press the tire edge and lead the tire edge into
steel hook slot.
The tire edge can not slide out of the head of
the tool head.
Note: When you mount/ demount the tire, tire
rotates clockwise. If the tire is jamming during the pro-
cess, please stop working and counterclockwise rotate
the tire to remove the jamming.
Do not place your hand on the tire. When the
hexangular shaft comes back to its work position, the
hand between the rim and the tool head may be crus-
hed. Remove the objects may cause the danger to the
operators such as bracelet and loose cloth etc. To avoid
the accident, when the turntable rotates, you should
keep your hand and the other part of your body away
from the tool head as far as possible.

18 | TCE 260 | Inflation
6.10 The process for mount/ demount the
special wheel
RSome special rims, the groove at the middle of the
rim is very shallow or without groove. As shown in
figure below:
RThe demounting process for the wheel, demount up-
per tire edge is different, the hook can’t fully catch
the suitable position, the operator need to find best
position according to operation situation, which can
be reduce resistance for wheel.
7. Inflation
7.1 Warning
Warning
The explosion may cause serious damage to the ope-
rator even death. So you should be more careful and
strictly follow the following use instruction. For the rea-
son that some protective devices are not designed and
manufactured, the operator must wear the goggles and
related protection.
Note
During operation, the noise may reach 85dB(A), so the
operator should wear the related protective devices.
Danger
The machine is equipped with inflation pressure limit
valve, but if the condition of tire and rim is not good or
the operation is incorrect, there is still the possibility of
tire burst.
Danger
Do not exceed the max pressure nominated by the ma-
nufacturer.
During the process to inflate, the operator should keep
away from the tire as far as possible.
1. Carefully check if the size of the rim is same to the
size of the tire.
2. Check the wear state of the tire or whether there is
damage or not.
3. During the process to inflate, frequently check the
pressure inside the tire.
4. The max. inflation pressure is 3.5bar, under any cir-
cumstance don't exceed manufacturer recommend
pressure.
5. The hand and body should be kept away from the
tire.
7.2 Vacuum tire inflation
1. Secure the rim is firmly fixed on the turntable and
the tool head and the tire pressing disk has been
kept asway from the tire. If possible, it should be
positioned to the farthest point.
2. Mount a new nozzle at the rim.
3. Secure the tire has been completely lubricated.
4. Take out the cup of the nozzle and clamp the gun at
the top end of the core to inflate the tire.
5. Frequently stop inflation and check the pressure in-
side the tire, not exceeding 3.5bar, until the pressure
inside the tire meet the requirement and avoid the
tire pressure not exceeding the max pressure.
6. Vacuum tire needs relatively large air flow. If air flow
is not enough, the bead should not transit the hump.
To increase the air flow, you can take out the core of
the nozzle. As figure, it is very good for the safety of
the car when in runs on the road.
7. Check. The junction between the bead and rim must
be perfect. If there is problem, you must deflate
the tire and repeat breaking bead and lubricate the
bead. Rotate the tire and then inflate the tire.
8. Attach the core to the nozzle.
9. Connect the inflation gun and then press the deflate
button to remove the residual air.
10. Mount the nozzle.
7.3 Inflate the tubed tyre
1. Secure the rim is firmly fixed on the turntable and
the tool head and the tire pressing disk has been
kept from the tire. If possible, it should be positi-
oned to the farthest point.
2. Secure the tire has been completely lubricated
3. Remove the nozzle, put the inflation gun head to
the air tap head, step down the inflation pedal then
inflate to tire.
4. Push the nozzle on the tube to deflate the air bet-
ween the tube and tire. Or the tube will be damaged.

5. Frequently stop inflation and check the pressure in-
side the tire, not exceeding 3.5bar, un-til the pressu-
re inside the tire meet the requirement and avoid the
tire pressure not ex-ceeding the max pressure.
6. Attach the core to the nozzle.
7. Connect the inflation gun and then press the deflate
button to remove the residual air.
8. Mount the nozzle.
7.4 Tire pressure
1. Securing the correct tire pressure is very important
to the safety of the wheel.
2. The low tire pressure will cause the tire to be too
heat and with serious wear. And the life of the tire
will be shortening. The inside of tire will be damaged
and the oil consumption will be larger.
3. The high tire pressure will cause easy damage when
clamping and the tire wall will be seriously worn.
4. You must check you tire pressure one a week. You
should prepare a spare tire before you start a long
distance journey.
5. Check the tire pressure under the normal tire tem-
perature, not check when the tire temperature is too
high or too low.
6. Normal tire temperature means the vehicle has not
run for more than one hour or the run for not more
than 2-3km in low speed.
7. The tire pressure under normal tire temperature
should meet the requirement of the car and the tire
producer.
8. When the can is under heavy load, if the tire pressu-
re are not special specified, normally speaking, the
tire pressure will increase by 0.3bar.
