Using this sausage gun is easy. First, choose the right cartridge or sausage refill that fits the gun. Insert it into the gun. Then, you can use the 360° rotating handle to position the gun in the tight space where you need to dispense the material. Push the plunger forward to release the material. Thanks to the Auto Flow System™ Plunger, you can stop the flow easily by just releasing the pressure. When you're done, remove the plunger for cleaning. Make sure to clean the gun regularly to keep the anti - residue surface working well. Also, store it in a dry place to prevent damage. Don't force the plunger too hard as it might break the mechanism.
