Suggestions on keeping your Big-Bang® Cannon ready for action
Store Bangsite® in a dry/non-humid location. Wash out with water after use. Warm water and vinegar will remove white sediment (lime) from cannon.
When ordering Bangsite® for your cannon, also get our specially made Spark Plugs. One Spark Plug should last about as long as a tube of Bangsite®, which produces about 100 shots.
If the cannon doesn't fire
Make sure you've added the correct amount of water. Check the firing pin to make sure that it creates a spark. The chamber should be completely closed when firing. Blow into the Ignitor opening after every shot to clear any remaining gas which will create the best condition for the next shot.
Check the Spark Plug in the Ignitor and replace as necessary.
