Step 9: How to Load and Fire

Put one rubber band on the tip of the barrel and stretch it back onto the white rod on the cogwheel the is straight up. the while holding the cogwheel release the handle part a bit forward and pull the cogwheel back until the next white rod touchs the handle bit and reapeat. To fire it, all you have to do is use the rods on the cogwheel at the bottom of the gun as triggers. Pull it back until it fires and the handle should stop it from firing the whole magazine. However if you put on about 6 or more rubber bands it can sometimes fire 2 or 3 rubber bands at a time. So put a little bit of pressure onto the handle when you fire.
