Lowering slowly

• Checking method:

  1. Check whether the frame of front wheel is rusty or whether there is mechanical interference. (Not within the scope of warranty claim)

  2. Check whether there are impurities stuck in the lowering solenoid valve. If yes, clean the valve and replace the oil vlinder.

  3. If the above causes are ruled out, then hydraulic pump station is faulty, and it needs to be replaced.
