6 Operation
Please read the instruction manual carefully and note before use.
The operation of semi-automatic tyre changer is divided into the following three parts:
Breaking the bead/demount tire/mount tire.
Discharge all air from the tire and remove the balance lead from the tire.
Mattersneedattention:
● More and more motorcycle rims are made from special materials such as aluminum magnesium
alloys and carbon fiber, In order to lock into this kind of rim , must use special repair tool of the
motorcycle tire.
● To avoid damage, The maximum pressure limit of working plate is 8 bar.
You have to be very careful when you are operating bead breaker. When the pedal
is operated, the breaker arm will swing rapidly and forcefully, and any object
within the movable range of the breaker arm is at risk of being crushed.
●Check the tire to see if it has emptied the gas. If not, empty the gas
● Please close the clamp jaws of the turntable.
Do not place your hand on the side wall of the tire during operation of the
turntable. The clamp may be pressed to your hand when it is open.
●Lean against the tire on the rubber pad (S) on the right side of the automatic tyre changer.
●Press the bead breaker closer to the edge of the rim 1cm (figure 8).It should be noted that the bead
breaker should be placed on the tire instead of the rim.
●Step on the pedal (U)，and the pressure device is started. Release the pedal when the bead breaker
completes the operation or the rim is off.
●Gently rotate the tire and repeat in the rest of the tire until the flange is completely off the rim.
Repeat on the other side of the tire.

Before any operation, check to see if the tire is out of air. And ensure that
the balance lead has been removed from the rim.
Apply special lubrication to the rim.
Failure to apply lubricant may result in wheel rim damage.
Do not put your hand under the tire when you lock the rim.
To properly lock the tires, place tire in the center of the turntable.
Clamp the rim outside
●step the pedal (Z1), clamp (G) will open.
●place the tire on the clamp so that the rim is near the lowest part of the clamp and step
on the pedal(Z) to the bottom.
Clamp the rim inside
●make the clamp (G)closed completely。
●Place the tire on the clamps and step the pedal (Z1)to clamp the rim.
Make sure that the rim is firmly fixed to the clamps.

Don’t put your hands on the wheel: if you put your hands between rim
and mounting head, it may getting hurt when column return to its
position.
original
●Lower the operating arm (M)，until the dismounting head is supported on the rim edge
and locked with the locking handle (K).In the process, the operating arm is locked in a
fixed position in the vertical direction, and the working head is moved to 2mm above
the rim.
Note: Once the operating arm is locked in the vertical direction ，the working head must
be manually removed from the rim (approximately 2mm) with the manual wheel
on the left side of the horizontal swing arm.
●Insert a crowbar (T) between the rim and working head (I), and hang the rim outward on the
working head (I) with the help of the crowbar (T) (Figure 10).
Note: if there is an inner tube, in order to avoid damage to the inner tube, the tire valve should
be at a position about 10cm away from the right side of the disassembly head (I) to start
the tire removal operation.
●Hold the crowbar in this position and press the pedal (V) to turn the chuck (Y) clockwise
until the tire is completely removed from the rim.
When the turntable is running, keep hands and other parts of the body away
from moving parts as far as possible to avoid injury.
When the turntable is running, keep hands and other parts of the body away from
moving parts as far as possible to avoid injury.
●If there is an inner tube, remove the inner tube, repeat the same operation on the other side
rim.

Note: in order to prevent tire bursting during inflation, it is very
important to check the tires and rims. Before assembling the tires, it is
necessary to pay attention to:
● check the tires, and do not install them if there is any damage.
● check the rim for dents or deformation, especially alloy rims. There
will be small cracks inside the convex marks, which can not be
distinguished by naked eyes generally, which will damage the
durability of the rim, so it will also be dangerous during inflation.
the diameter of rim and tire must be consistent. Do not install tires
when it is not sure about the diameter and dimensions of the tires are
consistent or not.
●Applying special lubricant on the flange can prevent the flange from being damaged and
make the installation more convenient.

Do not put your hand between the wheel rim and the fixture in the process of operating
the fixture, so as not to hurt your hand.
Note: when operating the same size rim, it is not necessary to repeatedly open or close the
operating arm (M), just move the set horizontal swing arm (N) to the side.
Don't put your hand on the tire: when you move the operating arm back to the working
position,you may be hurt if you put your hand between the rim and working head.
●Move the tire to make the bead passes below the front section of the mounting
head, along the mounting head to make it the above the rear section of the mounting
head.
●Press the rim into the groove of the rim by hand, step on the pedal ( V) , and turn the
turntable clockwise until the rim completely falls into the rim (Fig. 12)
keep your hands and body as far as away from the operating arm to avoid body
injury.
●Insert the inner tube, if there is one. Repeat the above operation for the other side of
bead.
Note：Turntable is always rotating clockwise during mounting and demounting process,
unless the machine is something wrong or operating mistakenly, it may rotate
anticlockwise.
