Dennison Fine Fabric Gun

Yes, it's the Dennison locking mechanism (DL1) .

Often customers think that as long as the tip of their Dennison needle is sharp, and going through the fabric with ease that there is no need to change the needle. This is NOT TRUE. The needle should be changed when the customer notices they have to squeeze the trigger harder than usual, or as soon as they see any signs of “jamming”. Why? Because the back end of the needle actually has a V shaped or C shaped (depending on what kind, plastic or metal, or what brand) blade that is clipping the fastener off the clip. When this blade begins to dull, that is when the gun will start to jam.

There are a couple of reasons why this may happen. If the fasteners jammed inside the gun, and the trigger wasn’t held in to remove the fastener clip, this could cause the ejector rod to bend. If the needle is bent this could happen if the gun is tossed onto the counter, if the gun was dropped, or if the needle was forced through some heavy material) the ejector rod will also start to bend from rubbing up inside the needle. Also, if the needles are dull and the fasteners are not being severed properly, the ejector rod will start to bend while trying to force the fasteners through the needle. Dull needles and bent ejector rods are the main reason why the guns will jam.

Make sure that the needle locking mechanism hasn’t moved out of the gun. Sometimes when this locking mechanism is turned- it slides out of the gun a little and acts as a barrier to the needle, either not allowing the needle to leave the gun- or be inserted into the gun.

Jams in the gun could be caused by a number of things: 1. Is the needle channel obstructed in any way? - Try cleaning the channel or change the needle. 2. Has the pusher that forces the fastener out of the gun been damaged? - If this part of the gun has been bent by trying to force the fasteners a new gun may need to be purchased. 3. Is the needle in the gun properly? - Make sure that the long slot of the needle is lined up and parallel to the long open slot of the gun. 4. Are the fasteners in good working order? – Fasteners in time may not be as functional, they are made of either nylon or polypropylene which absorb and release moisture when sitting around. As they get older the will become more brittle and may not function as well. Try changing the fastener clip. Are partially used clips being removed from the gun properly? – Make sure when removing that the trigger is pushed in fully, and proceed by lifting the clip upward.
