The tire changer(tyre changer) is a necessary repair equipment for 4S shops, auto repair shops and tire shops. When using the tire changer(tyre changer) in automobile maintenance, there will be some tips. Here is a brief description of the tire changer(tyre changer). The small skills in the use process, I hope to help friends who are just beginning to learn tire disassembly:
- For tires with good but soft rubber at the top of the tire: When using a shovel to skid the tire, you can slightly lift the shovel control pedal, and push the tire in at the same time, make sure that the shovel is in contact with the tire, and then use the Or hold your hand to prevent the tire from returning, and then step on the control pedal, it is easier to shovel the tire.
- For tires of sports cars for a long time: The tires are exposed to the internal pressure for a long time, and the heat generated by the friction between the tires and the ground causes the tires to adhere to the steel ring. When the air shovel is difficult to remove, you can first dissolve the detergent in water and use a small brush to brush some solution on the lip and the steel ring. After the solution penetrates into the gap between the lip and the rim, use the air shovel Under the tire.
- For tires with a harder tread: It is best to use a trolley spring steel plate when picking up a tire, and make a long crowbar to pierce the tire's head to make it easier. When putting on the tire, press the belly with both hands. When the gap is about 200mm and the tire is at the tightest point, press the belly firmly with the right elbow. At the same time, push the tire clockwise with your left hand to prevent the motor and V-belt from slipping. It also protects the motor.
Tire disassembly steps.
Open the lip, open the lip.
Key points: unloading the valve core; unloading points: unloading the valve core; unloading the balance block; lip lubrication; balance block; lip lubrication; diagonal pressure tire. Diagonally press the tire.

Installation of tires
Lock the rim on the turntable, and lock the rim on the turntable.
Place the tire bead on the disassembler, and place the tire bead on the disassembler, with the left end facing upward, the same as above, and the left end facing upward, and simultaneously press down the belly.
Press down on the belly.
- Lubricate the wheel with thick soap liquid. Lubricate the wheel rim with thick soap liquid. Rotate the disc clockwise. The edge rotates the disc clockwise to allow the bead to fall into the rim.
How to use tire changer(tyre changer)
A) Control method
- Press the second foot pedal on the left and release it when you hear the sound of "click". At this time, the supporting claws do not move; repeat once, the supporting claws move inward; repeat again, the supporting claws move outward and recover To the initial position. 2. Pull off the detachable arm of the rim, step on the second foot pedal on the right side and keep stepping on it. The large cylinder drives the wheel-level detachable arm to move inward and incompetently. Rims isolated. Release the foot pedal, and the large cylinder returns to the initial position. 3. Press the pedal down while the first foot is turned, and the table rotates clockwise; otherwise, raise the pedal, and the table rotates counterclockwise. 4. Move the locking handle downwards to release the vertical and horizontal axes at the same time; otherwise, push the locking handle upwards to lock the vertical and horizontal axes at the same time.
(2) Disassembly and assembly methods of tires
- Clean the air of the tire to be disassembled. 2. Press the tire detachment sheet to separate the tire from the steel rim. 3. Place the tire on the workbench to support it (or clamp it tightly), adjust the position between the disassembly head and the tire and lock it. 4. Apply lubricant to the edges of tires and steel rims. 5. Use a crowbar to pry the edge of the tire onto the disassembly head, without pulling out the crowbar. At this time, rotate the table clockwise to remove the tire. Use the same method to remove the tire on the other side. 6. When installing the tire, press the edge of the tire with the disassembly head, and turn the table clockwise to complete (still apply lubricant). Use the same method to install the tire on the other side. 7. When inflating the tire, the inflation pressure can be read from the inflation meter.
(3) maintenance and precautions
- Before performing maintenance, you must disconnect the power and air supply. 2. At the end of each day's work, the machine must be carefully wiped, and the sliding and transfer parts are often oiled and lubricated. 3, often check the gas-water separator and oil mist. When there is too much water, release it in a timely manner, and replenish it in time when the amount of oil is insufficient (use 20 or 30 spindle oil). 4. Make sure that there is enough lubricating oil (mechanical oil No. 20) in the gearbox. The oil level can be
