CHAPTER 4 DEMOUNT AND MOUNT TIRE
Note: the operator must be trained and qualified then allow to operate the tire
changer.Need to use the proper device and tools, wear the protective clothes, and
use the proper safety precautions, like goggle, earplug, and safety shoe and so on.
4.1 BASIC PRINCIPLE
In order to avoid damage the rim, especially the alloy rim, when mount and demount the
ire, must use the specified crowbar.
In order to facilitate the removal and protection the tire and rim, between the tire and rim,
at the position which the bead break blade insert to, need to lubricate using industrial
lubricants or soap water.
For certain types of tires, pay attention to the tire wall and the rotation direction marked on
the tire.
The tire size must be suitable for the rim to mount.
Before mount and demount the tire, need to check whether the rim had damage
(deformation or surface of the outside of the rim, rim axial for radial beat is too big,
corrosion or overall wear).
In any case, pay attention to the mounting and demounting request of the special tire from
the tire manufacturers.
When inflate the tire, to increase the pressure uniformly and pay attention to the tire edge
situation.
4.2DEMOUNT TIRE
Deflate the air in the tire completely and
pull out the core. Use the special tool to
detach the weight on the rim. Place the tire
between then bead breaking blade and
tire pressing runner clog(FIG15).
Then step down the tire press
pedal(FIG3-11) to detach the rim from the
tire. Repeat the same operation on the
other parts of the tire to make the tire
completely detached from the rim.
Move the hexangular shaft to the working position to make the demount tool close to the
rim of the wheel. The cylindrical roller in the demount tool will contact with the external rim
of the rim and the bottom of the demount tool will contact with the surface of the rim.

- 9 -/ 19
Press the lock handle press button(FIG3-3)
to lock horizontal arm and hexangular shaft and
the hexangular shaft will automatically move
upwards. The quadric shaft will automatically
backward a little to make the demount tool
detached from the rim of the rim to avoid the
damage on the rim(FIG16).
NOTE: The angle of the demount tool has been
calibrated according to the standard rim (14"). If
handling the extra-big or extra-small rim, you
can reposition.
Use the crowbar to detach until the lip to the hump of the demount tool (FIG17). Step the
turntable rotation pedal(FIG3-12) to rotate the turntable clockwise until the rim of the wheel fall
off.
If the demount of the tire is jammed, please stop the machine immediately and
then lift up the pedal to let the turntable rotate counterclockwise to remove the
resistance!
Take out the tube and then move up the lower lip to contact with the upper edge of the rim
and detach another lip (FIG18). Step the column tilt pedal (FIG3-9) and the column tilt
backwards and at this moment, you can take off the tire.
4.3Mount tire
Clean up the oil and rust on the rim and lock the rim on the turntable.
Spread the lubrication liquid or soap liquid around the lip. Tilt the tire against the rim and
keep the front end upwards. Press down the column tilt pedal (FIG3-9) to make the
column return to the original position. Move the demount head to firmly contacted rim
(FIG16). Position the left of the lip above the tail of the demount tool and the right under
the hump of the demount tool (FIG18).

- 10 -/ 19
Press down the right side of the tire as hard as you can and step turntable pedal (FIG3-12)
to rotate the turntable clockwise to guide the lip into the tire detach slot completely.
If there is tube, raise up the demount tool and put in the tube and position the core.
Mount the demount tool again. Adjust the
position of the upper lip. Use the assistant
press roller and press to press the side of the
tire to make partial of the lip into the tire
detaching slot (FIG24). Step the turntable
rotation pedal to rotate the tire. At this moment,
continue pressing the lip just mounted on the
rim.
When 10~15cmof the tire not into the rim,
change to the step mode. And observe the condition of the tire to avoid the tear of the tire.
Once you feel there is any tear on the tire, release the pedal at once. Then lift up the
pedal by instep to make the motor rotate reverse. Make the tire restore to the original
condition to mount again.
4.4 Inflation
NOTE: When inflating the tire, please be carefully and series obey the operation process.
Check the air route to see if the air connection is OK. This machine is equipped with an
inflation device for monitoring the inflation of the tire and the inflation pressure.
Loose the tire from the turntable.
Connect the inflation hose with the tire air core.
In the process of inflation, you should repeat stepping the inflation pedal. Confirm the
pressure indicated on the pressure gauge not exceed the scope specified by the

- 11 -/ 19
manufacturer. In this machine, there is a pressure decrease valve to keep theinflation
pressure not exceed 3.5bar.
For tubeless wheel with lax tire, the common inflation is invalid and can use the quick
inflation then common inflation. (The quick inflation function is not standard configuration
and need to special order).
Step down the inflation pedalto the bottom position (second gear) and quickly release the
pedal when the tireis full to the position of the first gear.
Note: the machine equips the reducing valve and set the pressure value at 3.5 bar. Customers
can get different inflation pressure by adjusting the pressure decrease valve according to their
own requirement.If the inflation pressure too high, you can press down the deflation press
button on the inflation device to reach the required air pressure.
Warning! Explosive!
When inflation, you must follow the above safety operation and abide by the following
instruction:
Carefully check is the size of the rim same to the size of the tire and also check the wear
condition of the tire to secure there is no damage before inflation.
When the inflation pressure is relatively high, you should remove the tire from the
machine and inflate in the protective cover.
When inflate the tire, be carefully, keep your hands and body far away from the tire.
Chapter 5 Repair and maintenance

- 12 -/ 19
Note:Only the professional personnel can repair. Before any operations of repair
and maintenance, you should power off and the power plug should be monitored
by the repair personnel, meanwhile switch the pneumatic source and deflate the
residual gas.
To correct use the tire changer and prolong its life,repair and maintenance in accordance with
the operation manual is necessary. Or the running and reliability of the machine will be effected
and the operator or the personnel around the machine will be injured.
5.1 The following parts will be maintained monthly:
Keep the clean of machine and working site.
Use the diesel oil to wash the hexangular shaft and quadrichorizontal arm (Fig20).
Use the diesel oil to clean the turntable jaw and guide railand use the Lithium grease to
lubricate.
Periodically check the height of the in the oil fogger. If itis lower than the oil scale, please
fill in the SAE30 grease. Periodically drill out the water and impurity in the oil-water
separator.
Periodically check and adjust the tension force of the transmission belt and properly
adjust the adjustable nuts at the A and B position to adjust the tension of the belt.
Check all the connecting part and tight the loose bolts.
5.1 The adjustment on the clearance between the tool head and rim.
Switch off the pneumatic source and detach the protective cover on the hexangular
shaft.If the clearance if too much, we can adjust the nuts (Fig21-A) on the vertical

-13 -/ 19
hexangular shaft downward by 16# spanner;If the clearance if too small we can adjust the
nuts on the vertical hexangular shaft upward.
Switch off the air source and detach the protective cover at the upper end of the horizontal
arm.Use 5# spanner to loosen the lock nut (Fig21-C)on the M6 screw at the two
end.Adjust the M6 screw,meanwhile use your hand to push the quadric shaft until it runs
smooth and thenlock the nut.Use the spanner to adjust the screwin the middle and
meanwhile lock the horizontal arm and observe the displacement. When the displacement
is 2mm,lock the nut.
If the square locking plate cannot lock firmly, adjust the taper locking pole.(FIG21-D)
CHAPTER 6 TRANSPORTATION
When transport the machine must apply the original package and place according to the mark
on the package. The machine must be transported by the forklift with the corresponding
tonnage(Fig22)and the stacked layer will not exceed 3layers.
