Chapter VIII Faults and Troubleshooting

8.1 Stuck work tray
Maintenance idea: First of all, distinguish between circuit fault and mechanical fault.
Maintenance method:
- Step on or lift the two direction switch pedal, and observe the motor response. If there is no response, use a multimeter to measure
whether the voltage between terminals is normal on the two direction switch. If the voltage is abnormal, check the power supply line
or power plug. If the voltage is normal, use a multimeter to measure whether the voltage between and terminals on the two direction
switch is normal when stepping on or lifting the power switch pedal. If not, the two direction switch is broken. If normal, the motor or the
capacitor is broken.
- If the motor is buzzing but cannot rotate, the measurement method is the same as above. If the measurement result is abnormal, the two
direction switch is broken. If it is normal, turn the gearbox belt pulley by hand. If it cannot be turned by hand, the gearbox is faulty. If it can
be turned by hand, the motor or capacitor is faulty.
- If the motor can rotate normally and the work tray does not rotate, it shall be a gearbox fault, such as: failure of gearbox pulley to drive
the worm to rotate; the worm gear outburst, etc.
8.2 Tire dismounting inability
Maintenance method: Observe the working conditions of the motor during tire dismounting. If the motor cannot rotate during tire
dismounting, it means that the torque of the motor is too small or the capacitor is faulty. If the motor can rotate, but the pulley is slipping,
the explanation is that the belt is too loose. Just tighten the belt.
8.3 Failure in clamping the steel ring by the claw
Maintenance method: Check whether the air source pressure meets the requirements of the instructions. If it meets the requirements,
check for air leakage or gas blow-by. If there is no air leakage or gas blow-by, the explanation is poor concentric height of claw.
8.4 Failure in tire pressing for large cylinder
Maintenance idea: In case of tire dismounting inability (including the movable large cylinder and loose tire pressing under no load), the air
pressure is generally low, and air leakage or gas blow-by occurs in the large cylinder. If the large cylinder cannot move under no load, the
general explanation is that the compressed air is not applied to the tire pressing end of the large cylinder.
- Check whether the air supply pressure meets the requirements of the instructions. If it meets the requirements, check whether there is
air leakage in the large cylinder. Check the air pipes at both ends of the large cylinder. Connect the air source. One of the two air pipes
on the five-way valve shall be ventilated. When stepping on the tire pressing pedal, the other air pipe shall be ventilated. If it is abnormal,
replace the five-way valve or adjust the installation position of the five-way valve to make it work normally.
- If the five-way valve is checked to be normal, connect the air pipe at the reset end. The explanation is normal if the nozzle at working end
of tire pressing is not ventilated. If it is ventilated, the explanation is that the piston of the large cylinder is cracked or the sealing ring is
worn.
- Air pressure check: Use air pressure gauge to check whether the air pressure at the inlet end of the oil atomizer meets the requirements
of the instructions. If the air pressure at the inlet end is insufficient, turn up the air supply for the air compressor. If the air pressure at
the inlet end meets the requirements and the air pressure at the outlet end is insufficient, adjust the pressure regulating knob of the oil
atomizer. If the pressure regulating knob does not work, replace the oil atomizer.
