Sounding Barrel
Stabilizing Stand
Attach the cannon to the stabilizing stand by sliding the square bracket
at the base of the barrel over the top leg of the stand. Make sure the
cannon barrel is angled upward and secure on the stand as shown to the
right.
Extend the barrel by twisting the inside tube. Lengthening or shortening
the barrel controls the cannon’s sound output. A fully extended barrel is
the loudest setting.
Connect the gas regulator to any standard 20 lb propane (LP) tank
by inserting the coupler into the propane tank’s valve and fastening
securely. This must be a clean, secure connection for proper operation.
After placing the cannon in the intended area of use, check for gas leaks at each connection point. There should be no presence of
gas with the propane supply tank fully open.
Blast frequency is set by adjusting the knob position on the provided regulator. Use the indicator lines (+ to –) on the control knob
to adjust the blast frequency between 30 seconds to 30 minutes. Turning the control knob fully counterclockwise (+) increases the
gas ow and decreases the time between blast intervals. The minimum time between blasts is approximately 30 seconds. Turning
the control knob fully clockwise (–) decreases the gas ow and increases the time between blast intervals. The maximum time
between blasts is approximately 30 minutes.
Fully open the valve on the propane tank. The initial 2–3 blasts may sound weak; however, subsequent blasts will resound at
80–120 decibels depending on the extension of the barrel.

• Always wear ear protection while operating the cannon. Without ear protection, temporary or permanent hearing loss
may occur.
• The cannon should be placed on at ground, pointing in the same direction as the wind. This will maximize sound coverage
and eectiveness, and help prevent debris from entering the barrel.
• Do not place any objects inside the barrel, and always check that the barrel is free of debris before operating the cannon.
Never stand in front of the cannon or look into the barrel while the cannon is in use.
• The propane tank should always be standing upright, and never placed in front of the cannon barrel.
• Keep the cannon and propane tank away from any ammable material, and keep clear of any heat sources. If you plan on
placing the cannon on top of grass, rst lay a non-ammable material down to cover the grass before using the cannon.
• If there is a re, close the valve of the propane tank and extinguish it with a dry-chemical re extinguisher.
