8) Arrange and fix the hose to avoid the accidents caused by the clutter of the hose in the
process of use.
4. Necessary condition for the test
Operate the 098D auxiliary arm must make the tyre changer and air compressor connest well,
and ensure input the compressed air of 8-10bar steady pressure.
The connection of the tyre changer and air compressor is as below:
Caution: Before installation and connection, check to be sure that the electricity power supply
corresponds to the machine technical data.All the installation of electric and pneumatic devices must
be operated by a professional electrician.
Connect the compressed air connector which is on the machine right side with compressed air
system. The electric grid that the machine connects to must have fuses protection device and good
outer cover grounding protection. Install the leakage automatic air switch on the maim power supply;
leakage current is set at 30mA.
Caution: No power plug for this machine, the user should self-connect one power plug no less
than 16A as well as in line with the machine voltage. Or directly connect with the power supply
according to the above requirements.

5. Operation
Helping arm at right side is auxiliary device of tyre
changer for helping operator to demount and mount tyre.
5.1. Components
The operation component of the auxiliary arm is the
rise-fall control valve D, the function as below:
The rise-fall control valve D is used for lifting the tire
pressing roller assembly to suit all the required height of
demount/mount tyre changer.(fig 2) The control valve D up,
then the tire pressing roller rise; the control valve D down,
then the tire pressing roller fall.(fig 6)
5.2. Operation
It is difficult to demount and mount big low profile tyre.
If operation is proper, it is very easy to use helping arm
device to demount and mount tyre from rim. The helping arm
device may also be used when demounting and mounting
normal tyre with resistance.
a. Clamp rim
Firstly, press both side tyre loose as per operation
instruction in user’s manual. Force of demounting and
mounting is big when helping arm device is used.And rim
may be damaged easily. It is recommended that to clamp rim
from outside（jaw protector may be installed on jaws）. Tread relevant pedal to make jaws open to
clamp edge of rim, move helping arm’s rotary arm to far-end. Put on tyre, tread relevant pedal to make
jaws close and to approach rim
b. Demount tyre
1. Press tyre with tire pressing roller assembly to a position 3cm lower than rim edge, lubricate
tyre bead, rotate turntable, lift tire pressing roller assembly. (Fig 7)
2. Move demounting/mounting head close to edge of rim, keep a 2-3mm gap between
demounting/mounting head and rim plane，operate locking handle（K，Fig 9）to lock vertical arm，
adjust screw bolt in column to position swing arm, make sure 2-3mm gap between
demounting/mounting head and rim edge side

3. Nearby demounting/mounting head, insert lift lever N into tyre，use lift lever to lift bead upon
knob of demounting / mounting head. Manually rotate roller C to inner side，pull handle D down,
make roller C to press rim，keep 3-5mm gap between demounting/mounting head and rim, make
sure demounting/mounting head not damage rim, rotate turntable, demount tyre upper bead ( Fig 8).
4. Push handles D up, lift tire pressing roller assembly, loosen right pressing arm.
Lift tyre up, insert lifting level into bottom tyre bead nearby demounting/mounting head, lift bead
upon knob of demounting / mounting head and rotate turntable to demount down tyre bead.
c．Mount tyre
1. Lubricate tyre and rim edge with lubricant to avoid damage of tyre. Adjust height of
demounting/mounting head and make tyre bottom bead upon rear of demounting/mounting head and
below front of demounting/mounting head. Rotate turntable to mount bottom bead.
2. Make tyre top bead upon rear of demounting/mounting head and below front of
mounting/mounting head, move right pressing arm and make sure it is locked, pull handle D down to
make tire pressing roller assembly to press top bead to position below demounting/mounting head.
Lock tyre pressing head of 098D help arm on rim edge, rotate turntable, finish tyre mounting (Fig 10).
6. Maintenance：
Caution: please disconnect the machine from electric power supply and pneumatic power
supply.
Caution: only the professional persons can do the maintenance. To prolong the machine's life,
maintain the machine timely according to the manual. Otherwise, it will impact the reliability of the
machine or even cause injury to operator and others nearby.
Caution: before performing any maintenance, disconnect the tyre changer from the electric
power supply and pneumatic power supply, and tread the Jaws open and close Pedal or Turntable
Rotation Pedal for 3~4 times to evacuate all compressed air from the machine. Damaged parts must
be replaced by professional persons with the spare parts provided by manufacturer.
The specific maintenance please refers to the corresponding section of the tyre changer. If
there are any questions, please contact the manufacturer.
Trouble shooting table：
Note: In order to ensure the rise-fall control valve and the cylinder are reliable, the rise-fall
control valve should kept clean; the following instructions can be maintained.
The

shovel
operates
difficultly.
Jammed silencer Clean it or replace it.
The seal rings on the Bead Breaker
cylinder are broken. Replace it.
