FOR YOUR SAFETY
1. Protect your feet—always wear shoes when
operating the Pyroweeder.
2. Take safety precautions around children, pets,
and small animals.
3. Keep hands and feet away from burners while
the machine is operating. Flame may not be
visible in bright sunlight. The burner flames are
most visible when the Pyroweeder is operated
during lower light conditions, such as at dawn or
dusk.
4. Close the propane-tank valve when not in use.
5. Be prepared to promptly ignite the propane
upon opening the control valve for use. Do not
allow prolonged propane flow to un-ignited
burners. If excessive unburned propane flow
occurs, close the control valve and wait for
the propane to dissipate before attempting to
ignite the burners.
6. Keep the propane tank upright while operating
the Pyroweeder. It is recommended that you
use at least two bungee cords to secure the
tank against the tank brace.
Safety
IMPORTANT WARNINGS
1. Read all safety instructions before first use.
2. The Pyroweeder is intended for agricultural
weed management only.
3. Propane is extremely flammable. Before each
use, inspect hoses, valves, and connections for
damage or leaks.
4. Carbon monoxide gas is a poison—it can kill.
Since it is colorless and odorless, it is especially
dangerous. Incomplete propane combustion will
produce carbon monoxide; you can recognize
incomplete combustion by a yellow flame. On
the other hand, complete combustion produces
a blue flame. To operate the Pyroweeder safely,
adjust the pressure and control valve to avoid
a yellow flame—make it blue. Symptoms of
carbon monoxide poisoning include headache,
weakness, dizziness, nausea, vomiting,
confusion, and fatigue. If you have reason to
believe that you or anyone else has carbon
monoxide poisoning, move to fresh air and seek
immediate emergency medical care.
5. Prevent wildfires by complying with local
burn bans.
6. Practice fire safety—do not use on dry
grass, leaves, or brush, or during high fire-risk
conditions.
7. Do not operate in high-wind conditions.
8. Do not operate indoors or in an enclosed space.
9. Do not allow a child to operate the Pyroweeder.
10. Do not operate the Pyroweeder if your
coordination, balance, or judgment are impaired
by any medication, alcohol, or drug.
11. Do not store propane tanks indoors. Store
propane in a cool, well-ventilated outdoor
location.
12. Do not allow the Pyroweeder to tilt back onto
its handle while it is operating.

Thread Galling
Stainless-steel nuts and bolts are especially prone to a frustrating problem—thread
galling. As the nut is tightened on the bolt, friction between the contacting surfaces
may cause portions of the threads to break down and “cold weld” together. In the
most severe cases of thread galling, the nut and bolt will be completely jammed and
can only be separated by breaking the bolt or cutting the nut.
Thread galling can be minimized by using a thread lubricant when tightening thread-
ed stainless-steel fasteners. Don't force a nut that resists tightening before it is under
tension; loosen and try lubricating the threads again before proceeding.
Thread galling is not caused by defective parts. Thread galling on stainless steel fas-
teners can be minimized, but it cannot be completely prevented.
We have included a small pouch of thread lubricant; we encourage you to use thread
lubricant on all threads as you assemble your Pyroweeder.
I just want to say a personal “Thank You” for purchasing our
Pyroweeder. Our team has worked hard to develop a better
flame weeder on the market, and I’m excited to share it with
you!
I grew up on a small farm so I know firsthand how hard each
of you works at what you do; market gardening is not for
the faint of heart! I also know how important it is to have the
right tools for the job. Our goal at Farmers Friend is to make
well-designed, high-quality tools to improve your eciency,
profitability, and quality of life.
I see us all on the same team. You are growing the food and
flowers to make our world a healthier, happier place to live,
and we are developing the tools to make your work more
productive and enjoyable. Your success is our success! Keep
up the good work you are doing and we will remain focused
on supporting you with quality tools.
From the whole team here at Farmers Friend, I want to wish
you happy and safe flame weeding. May your days be filled
with more veggies and flowers and less weeds! Thank you
again for your trust in us.
