First, because many sealed movements and static rings are easy to crack, if you accidentally bump may be damaged, measures should be taken to avoid damage to the sealing of the car. Do not place sealing parts at will. Generally, clean fiber woven fabrics can be used for protection. Do not directly contact the cover with your hands and other objects. It is strictly forbidden to have any bumps in the transportation, inspection and installation process.
Second, avoid driving and sealing into other liquids to prevent damage. Under normal circumstances, unless there are special regulations, the rubber sealing ring in the seal should not be exposed to mineral oil or other oils. It is strictly forbidden to contact the corrosive chemical liquid.
