How to insert the needle into the tip of the tube
(without damaging the needle points)
Next Step

Move the needle inside the tube forward  and carefully insert the needle exactly in  the hole.  This method makes needle insertion foolproof without damage to  the fine needle points.

As soon as the needle enters the tip hold the tube  upright and the needle bar will fall straight in and the needle will be protruding out the bottom.   It is very important to keep the tube upright while putting the tube in the machine..
