Tire changer common faults

Fault	Possible Cause	Troubleshooting
The turntable only turns one way.	The universal steering switch is damaged.	Replace the universal switch.
The turntable does not rotate	Broken belt Damaged universal switch Motor problem Belt too loose	Replace the belt. Replace the universal steering switch. Check the motor power supply or wiring at the junction box. If the motor is burned out, replace it. Adjust the belt tension.
The turntable does not clamp the rim properly	Jaw wear Turntable clamping cylinder leaking	Replace the jaws Replace the cylinder seal
After pressing the pedal, the pedal cannot return to its original position	Pedal return spring damaged	Replace the pedal return spring
Abnormal sound from the transmission part	The motor's securing screws are loose. Foreign matter has entered the transmission system.	Tighten the fixing screws. Remove any foreign matter.
The motor does not rotate or the output torque is insufficient	Transmission stuck Capacitor breakdown Undervoltage Circuit breakage	Troubleshoot the stuck point Replace the capacitor Pause the tool and wait for recovery Troubleshoot
Insufficient cylinder output or air leakage	Air leak Mechanical failure Insufficient air pressure Damaged air pipe Damaged nozzle Loss of sealant	Strengthen seals Remove mechanical obstructions Replace compressor Replace relevant parts Add glue

Daily maintenance and care

Only qualified personnel should perform maintenance work. Before performing any maintenance work, disconnect the power cord and place the power plug within the maintenance personnel's monitoring range. Turn off the gas supply and push the gas switch to the "Off" position. Depress the large cylinder pedal and twist the clamping cylinder control handle to exhaust any remaining compressed air from the machine. To properly operate the wheel changer and extend its service life, regular maintenance and repairs as specified in the manual are essential. Failure to do so will affect the machine's operation and reliability, potentially causing injury to the operator or those nearby.

Note: The wheel changer should be maintained at least monthly.

1. Check the oil level in the lubricator cup. If refilling is necessary, first shut off the air supply, manually remove the cup, and fill it with pressurized SAE 30 mineral oil.
2. Clean all moving parts of the support wheel and lubricate them.
3. Regularly check and tighten all bolts on the connecting parts.
4. Keep the hexagonal vertical shaft or square shaft clean and lubricate them.
5. Check the drive belt tension. If necessary, adjust the adjusting nuts at points A and B downward to tighten the drive belt.
6. Keep the machine and work area clean to prevent dust from entering the moving parts.
7. All surfaces subject to displacement and friction should be lubricated weekly with a lithium-based grease.
8. The user should equip the air compressor with an oil-water separator to reduce the water content of the compressed air passing through the machine.

Safety Operating Procedures

1. Before first use, carefully read the instruction manual to understand the specific features of the machine.
2. Do not operate the machine without understanding its structure, performance, or operating procedures.
3. Do not repair or overhaul the machine while it is in operation.
4. If a serious leak or other abnormality occurs, the machine must be stopped to analyze the cause and eliminate it. Operation with the problem is not permitted.
5. Do not overload the machine or operate it beyond the maximum jaw opening diameter.
6. Electrical equipment must be reliably grounded.
7. Turn off the main power and air supply when the operator leaves the machine.
