parts of this gun are warranted to work when you receive it. Please check the
parts and the ignitor before you use the gun. If you find any parts that are
defective contact me by e-mail (larryb @ itis.com) or fax (608-846-8659). Parts
and performance are not guarantied after the gun is used.
1.5, 2 ,2.5 or 3 inch x 36 inch barrel.
4 inch clean out drain cap.
4 inch combustion chamber, with handle and spark ignitor installed.
Mini tennis ball shooter complete assembly
have designed the gun to have a screw in barrel and require no use of cement. To
assemble the barrel, screw it into the combustion chamber until it is seated
fully. The Spud Gun is now ready to use. Please
read the following warning and instructions before use of gun.

sure you are outside when shooting and loading.
Unscrew the clean out drain cap from the combustion chamber.
Take a potato
that is larger that the barrel. Push the potato onto the beveled end of the
barrel and it will cut the potato to the inside size of the barrel. For the
tennis ball barrel, wetting the ball will help it slide easier. Take a ram rod
and push the potato down to the end of the barrel (a yard stick will do fine).
Take your fuel
and point the nozzle towards the inside of the combustion chamber. Spray about 1
to 2 seconds of fuel into the chamber. Quickly screw that drain cap back into
the chamber. Be careful not to cross thread the cap.
Once the cap is
screwed into the combustion chamber, point the gun away from anyone or any
persons near you. Hold the handle and grip the barrel with the other hand. Press
the ignitor with your thumb and the fuel will ignite sending the potato in the
direction in which you pointed it.
After you have shot the gun, remove the cap and let the chamber ventilate
trying another load.
After several shots you may wish to stand the gun upright on the chamber
to let the
hair spray and moisture run out.
If you leave the cap screwed into the combustion chamber
when not in use it may
become stuck in the chamber. If this happens refer to the cleaning
If you have the Mini tennis ball shooter and are using the Binca
breath spray follow
the below instructions for different distances:
3 sprays = 30 yds
7 sprays = 70 yds
to do when it doesn’t fire:
LOOK DOWN THE BARREL!
fires are rare (but can happen). It is important have a good seal between the
potato and barrel if the potato does not fully plug the barrel it can cause a
miss fire or a very short shot. Use
about 1 to 2 seconds of spray. You want a fine mist which will atomize the air
and hair spray to get a good ignition. On windy days, the wind can blow the hair
spray out of the chamber before you get the cap on. Try shielding the chamber
from the wind when loading.

you get no ignition after spraying fuel into the chamber and pressing the
ignitor, remove the cap and let the chamber ventilate. If you apply too much
fuel, you can cause the ignitor tip to short out (like a fouled spark plug). If
you need to push the button 4 to 5
times before it fires, your wetting the tip. Try spraying away from the ignitor
tip. Also applying too much fuel
will displace the oxygen and cause miss fires. Let the chamber ventilate and dry
out. You can check for a spark by looking at the ignitor spark gap and pressing
the red button down and confirming the spark is jumping the gap. Make sure the
chamber is ventilated and free of fuel before looking down the chamber and
pressing the ignitor. If you get a
blue flame inside the chamber quickly blow it out or place the cap in the
chamber to snuff out the flame. The flame, if left to burn can melt the PVC pipe
and cause the chamber to dis-form.
clean your gun, (it can get sticky), I recommend using hot water and letting it
run through the combustion chamber. You may remove the ignitor from the chamber,
by unscrewing the jam nut that holds the ignitor in place. By tilting the gun at
an angle and making sure the ignitor is up, you can do a good job of cleaning.
If you get the ignitor wet, just let it dry before using again. There are no
electrical parts inside the ingitor.
the cap is hard to screw on, clean the threads of the cap and chamber with hot
water and a small brush. It is recommended to clean often, hair spray when left
to build up can be very difficult to remove. The cap threads will easily build
up hair spray and become difficult to thread the cap on completely.
types of fuel:
only recommend hair spray, but other spud gun site will give you examples of
other types of fuel. The ingredient in the hair spray is butane and other ignitable gases.
have used OFF insect repellent, Old Spice
body spray (this works great) when I have no hair spray. I do NOT
recommend other high ignitable gases such as gasoline,
acetylene, propane, pure oxygen, NOS, ETC. This device was made to have fun,
not hurt someone. Be careful what you shoot at. I have put a potato through ¼
inch fiber board at 50 feet by just using hair spray.
ignitor has 2 moving parts inside it, a spring and a metal rod. After many uses
it may be necessary to replace the ignitor. If the ignitor will not spark or
feels mushy, then it can be replaced. This ignitor can be purchased from places
that sell gas grill accessories. Look for the type that has a threaded base, NOT
the push-in type. If you cannot find one, you may purchase a new ignitor from
us, check the order form for prices. Send

cap is stuck in the chamber:
to the nature of hair spray, things can get sticky. If you leave you cap in the
chamber and it becomes glued and cannot get it out, try the following.
the threaded end of the combustion chamber in hot water. Hair spray is water
soluble and will dissolve. By letting the chamber sit a pan of hot water (not
boiling), it will loosen the hair spray and allow you to remove the cap and
clean it before using again.
