Operation

Please read the instruction manual carefully and note before operating the machine.

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.

Matters need attention :

• 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 motor cycle tire.
• To avoid damage, The maximum pressure limit of working plate is 5bar.

Breaking the bead

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 (V) 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.
  
  

Demount 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 between 10 and 20 inches

• Step the pedal (Z) to the central position and locate the clamp (G) according to the reference scale of the turntable.
• 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 between 13 and 24 inches

• Make the clamp (G) closed completely.
• Place the tire on the clamps and step the pedal V 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 original position.。

• 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 2mmabovethe 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.

• With the crowbar T interested between the bead and the front section of mounting head I, move the tire bead over the mounting head I with crowbar T(see pic.10).
  Note : In order to avoid damaging the inner tube, if there is one, it should be 10cmtotheright of the mounting head I about the above operation.

• While the crowbar in this position, rotate the turntable Y clockwise by pressing down on pedal V until the tire is completely separated from the wheel rim.
  Keep your hands and body as far away as possible from the moving parts when operating the machine, to avoid getting hurt.
