Flamethrower Manual

Owner’s manual for the Pyro-15 AR-Flamethrower, made by Sgt. Stitches Armory.


We’ll teach you how to use it soon, but first, we need to address what scientists call, “Natural Selection”.


Natural selection is a mechanism of evolution.


Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success.


Natural selection will be paying very close attention to you anytime this product is under your control.


If you do anything stupid, Natural Selection may well decide to completely remove your DNA from our gene pool.


In other words, this product can easily cause serious injury or death as well as severe property damage.


It’s up to you & anyone else who touches this product to ensure your own safety & the safety of others.


This could not be more of a “use at your own risk” product.


We make zero guarantees of any kind related to the functionality or safety of this product.


Leaks happen, parts fail & things go wrong.


It’s up to you to regularly inspect and to use this in a safe manner, and to not use it if it ever malfunctions in any way.


Neither Sgt. Stitches Armory nor the company you bought this from, nor anyone else, will be held liable for any damages or injuries associated with the voluntary use of this inherently, potentially dangerous product.


Moving on, is this legal to own? Yes, it is.


Flamethrowers are not regulated by the federal government.


Although this may look like a firearm, we have specifically engineered it so that no meaningful parts are interchangeable with any firearms, so it is not regulated by the ATF.


That said, it is the purchaser’s responsibility to confirm that ownership &/or use of this product does not violate any state or local laws or regulations.


Laws change all the time, but at the time this was written, there are only two states with any regulations that we are aware of.


California residents are limited to a 10’ flame and are required to purchase a permit or license after purchasing a flamethrower.


We can adjust your flamethrower before it ships to comply with the 10’ flame rule, but obtaining a license for it is up to you.


It is also the purchaser’s sole responsibility to determine what, if any, more or other, local city or state ordinances apply to your ownership &/or how you intend you use it.


We are having trouble getting clarification from Maryland, but we are told that they require an FFL license to purchase a flamethrower.


For that reason, we do not ship to residential addresses in Maryland, but we will ship it to your local gun shop.


As fun as this product can be, it is not a toy and as such, is intended for proper use by legally competent and mentally fit adults over the age of 18.


Like most of this manual, this should be obvious, but you must keep this product out of the reach of children.


Always inspect this product for leaks before putting a battery in it. If you notice any leakage, don’t use it and contact Sgt. Stitches Armory.


Never point this product in the direction of anything you don’t want to incinerate.


Do not touch the front end of the flamethrower, such as the nozzle or the electrodes as they will be hot during and after operation.


Do not adjust or touch the electrodes during use as you can not only get burnt, but you can also get shocked too.


If the electrodes, wire, or coil are damaged, don’t use it and contact Sgt. Stitches Armory.


Keep all body parts as far away from the nozzle as realistically possible during use.


Wind can be unpredictable & dangerous. Do not use this product if there is any wind present.


Do not expose this product to, or use it in extreme temperatures, such as above 99 degrees or below 0 degrees Fahrenheit.


Fuel can drip from the nozzle of this product at any time, which is another reason to always keep it pointed in a safe direction.


This product is intended to be used as flat as realistically possible. Do not angle or tilt it in any direction beyond 45 degrees.


Never disassemble this product.


Do not operate this product while under the influence of drugs and/or alcohol.


Do not remove the fuel tank or cap until the battery has been removed.


Refuel the tank(s) while it is sitting on firm & stable ground.


Never use this product indoors.


Alright! Now that we are past all the legal stuff, let’s learn how to throw flames!


First, put on your safety glasses.


Fully charge your battery.


Mix your fuel in a fuel safe container.


Although this product will throw & light nearly anything flammable, we recommend only using familiar flammable fluids that produce consistent results, specifically, gasoline & diesel.


Straight gas will produce a shorter ball of flame.


Adding diesel to your mix will significantly improve distance & make it easier to get a longer burn time, helping wet wood ignite easier.


The more diesel you add, the harder it is to keep lit, so we suggest not exceeding 40% diesel when mixing it with gas.


Do not use straight diesel. It is difficult to light, and you will spray a lot of unburned fuel onto the ground.


Do not thicken your fuel with an additive to make napalm as it will destroy your pump.


Unscrew your fuel cap and set it aside.


Nearly fill your tank with your mixed fuel, but don’t quite fill it all the way up, as we will be loosening the cap later & you don’t want fuel to spill.


Screw the fuel cap back on until it is snug.


If you spill or drip any fuel, be sure to get it cleaned up before putting a battery in it.


Wipe up any spills with a towel and use a non-flammable cleaner, like simple green, to clean up.


When using the standard octagon tank, your filling port & cap must be on the left, “driver’s” side.


When using the backpack tank, the notch cut out of the side of the aluminum block must be on the left, “driver’s” side.


Insert your fuel tank up into the bottom until it clicks into place.


You may find it easier to insert the tank by pressing in the oval tank release button, above the trigger and in front of the power switch, on the passenger side, to get it started going into place.


Give the tank a good pull to make sure it is properly locked into place.


Your flamethrower may have been built to accept DeWalt, Makita or Milwaukee batteries.


A battery is not included. You will need a battery that does not exceed 20 volts (V) or 2 amps (AH).


Using the wrong battery will immediately damage or destroy multiple components.


If you are not certain which brand of battery your model was designed to accept, please contact Sgt. Stitches Armory.


Insert the battery under the hand guard.


Now flip the rectangular switch on the passenger side, above trigger, from the off (O) position, to the on (I) position.


Your last step before firing is to loosen the tank cap a ½ turn to let it get some air flow.


If you forget this step, your flame will start out great but will quickly get smaller & shorter as it creates an air lock in your fuel tank.


Ready? Point it in a safe direction at whatever you want to incinerate and pull the trigger!


Every time you pull the trigger, the electrodes at the end of the barrel will arc and you’ll

emit a flaming stream of awesomeness.


Because changing external temperatures can change the internal pressure, causing the pressure to exceed the capabilities of the check valve, this product can unexpectedly start spraying flammable fluid out the tip on its own without warning, causing a safety hazard as well as damaging whatever it is near.


For this reason, you must run the pump after your tank is empty, until the pump runs dry.


Do not pull the trigger and run the pump once the fuel is exhausted for more than two seconds as you will permanently damage the pump.


When you’re finished, simply reverse the order of the startup process to make it safe for transport or storage.


Flame size & distance will vary significantly based upon several factors, including, but not limited to, altitude above sea level, barometric pressure, oxygen levels and fuel quality.


Your pump will continue pumping fuel well after your battery has gotten too low to spark the electrodes at the end of the barrel.


If fuel is pumping out but not lighting, start your troubleshooting by making certain that you have a fully charged battery.


If it still isn’t lighting, your electrodes at the end of the barrel may have been bent out of place.


If fluid is spraying between the electrodes, it will prevent them from sparking.


Never touch the electrodes until the battery is removed & they are fully cooled down.


Your electrodes can be bent by hand and should be spaced ¼” apart, and they should be close to the fuel stream, but just above it.


If you have any questions or concerns, please contact Sgt. Stitches Armory at (417) 429-3140
