Disadvantages of traditional refueling

Traditional oiling system is a defective system:
1It can not add oil to the main parts of the hook directly.

2It can not control the oil quantity in an accurate way. if the oil is added more, it may contaminate the fabric,machine and the floor.

3The oil can not be added well-proportioned. From the first head to the last head ,some maybe added with more oil while some less. The more heads the machine has, more problems it will arise.

4Oil leaking will happen if oil pipe union is aged or not install in a right way.

5The oil pipe will be jammed if oil stay long time in the pipe.
