WARNING: To reduce the risk of injury, all users must
read and understand this operator’s manual before
operating this device. Save this Manual for future
reference.

This flamethrower uses gasoline, which is a flammable
product. Failure to comply with these warnings and
instructions may result in an explosion or fire that may
cause property damage, personal injury, or death.
Read the instructions and warnings in this manual and
familiarize yourself with the flamethrower before using.
Review instructions and warnings periodically to maintain
awareness. Do not try to operate the flamethrower before
reading instructions.
3
Keep the flamethrower out of reach of children and
anyone who has not read instructions. Do not point the
flamethrower towards self, other persons, animals, or
objects. Never attempt to use the flamethrower as a
cigarette lighter..
Never attempt to modify the flamethrower construction,
and never use unapproved accessories or fuels.
Treat the flamethrower as you would any fine tool or
instrument. Do not drop, throw, or otherwise abuse.
Do not use a leaking, damaged, or malfunctioning
flamethrower.
Wear safety glasses and protective gear when using the
flamethrower.
Radiant energy can harm your eyes. Wear glasses with
an appropriate lens shade number.

Only use the flamethrower in well-ventilated areas.
General Safety Warnings

4
Never use the flamethrower near combustibles. Be
careful around motor vehicles or any gasoline-fired
products and beware of hidden fuel lines and tanks.
Do not attempt to ignite combustibles using plasma.
Be careful when using the flamethrower on windy days.
Wind may carry the flamethrower’s heat back toward
you or other areas not intended to be heated. Windy
conditions may also cause sparks to be blown into other
areas with combustible materials.
Heating an object may cause heat to be conducted to
adjacent objects that may be combustible or become
pressurized when heated. Always check to make sure no
unintended objects are being heated.
Do not touch the tip of the flamethrower. It can get
extremely hot during use. Take precautions to protect
yourself and others from accidental burns. Do not touch
plasma.
Never leave the flamethrower unattended when turned on.
Always have a fire extinguisher and a bucket of water
nearby when you use the plasma thrower.
This plasma thrower consumes oxygen and must only be
used in well ventilated areas. Do not use it in a confined
place.
Do not use if you have a pacemaker. The electrical arc
produces significant radio noise, and any impact it could
have on life-support devices has not been thoroughly
tested.
General Safety Warnings

5
Only charge batteries with the accompanying battery
charger.
Do not use in the rain or when relative humidity exceeds
75%
Do not place the device on the ground while attempting
to start the ignition process.
Do not put face or hands near the plasma.
Do not stare at plasma.
Only use fuels approved by Prometheus Industries. The
optimal fuel that we have found is diesel fuel.
