During the installation of the oil dipstick, please pay attention to the tightness of the interface. Need to use gaskets or unprocessed taps to improve sealing.2. The flow meter function will be tested before leaving the factory. There may be some oil on the surface of the product. This is normal. Just wipe it clean, it will not affect subsequent use 3. The reason why the oil gauge does not turn: If it is used in water, it will rust and get stuck. 4. A prefilter device must be added. The filter needs to be installed in front of the oil inlet, otherwise foreign matter will block the turntable.
