Q. What points do I check if my thermal
fogger will not start?
A. There are four general points to check.
Make sure you have (1) clean, fresh gas in the fuel tank, (2) spark when you
press the ignition switch (listen for the buzz of the coil), (3) air from the
compressor or pump, and (4) that you have used the clean out brushes to clean
the engine tube.
Q. Should I add oil to the gasoline of my
Pulse-Jet fogger?
A. No, this is not a 2 cycle engine. Use clean,
fresh gas with an octane rating of 85 or higher, leaded or unleaded. Add fuel
stabilizer to the fuel if the machine is used infrequently.
Q.
What is the recommended spark plug gap? Does the plug work while the engine is
running?
A. The spark plug should be gapped .060" (1.5 mm). The
plug is only in use while the ignition switch is being activated.
Q. How often do I need to check for carbon and use the clean out
brushes?
A. You should check after every 8 hours of
operation. Make sure to rotate the brushes clockwise so you don't damage the
brush. For more detail click here.
Q. How do I adjust the needle on the
carburetor?
A. Start the machine in the dark and you will see a
blue flame coming from the end of the engine tube (this flame is so blue that
you will not see it in the daylight). Adjust the needle so that this flame is
3-4" in length. Click here for more information on carburetor trouble shooting.
Q. What
flow rate should I set the machine for?
A. The more you turn the dial (numbered 1-10), the
larger the droplet you will make. About 5-6 will make a good small droplet for
killing insects, but if liquid ever starts to accumulate at the end of the
engine tube, turn the dial down. Click here for fogging
vs. spraying.
Q. Can I fog water based formulations in my
thermal fogger?
A. Yes, but better results will be obtained by
using models designed for applying water based solutions, such as the Mister III
or Mister Max. Click here for greenhouse applications.
Q. What
are the main points to check if a Pulse-Jet powered thermal fogger will not
start?
A. See our accompanying document, "Identifying a Pulsejet Carburetor Problem."
Q Do I need to add oil to the gasoline when
filling the fuel tank of a Pulse-Jet thermal fogger?
A. No. Due to
the fact that the Dyna-Fog Pulse-Jet engine in your machine has only one moving
part (the petal valve), it is not necessary to add oil to the gasoline. However,
we do recommend after every 25 hours of use that you add a gasoline conditioner
(Fuel Stabilizer) to help the fuel system of your machine stay clean.
Q. What should the spark plug gap be set to and will the spark
plug be working at all times, or only when starting the machine?
A.
The ideal gap on the spark plug of the machine should be .060" (1.5 mm). This is
a wider gap than what is used on conventional piston type engines and is
necessary to enable a "HOTTER SPARK" for quick starting. The spark plug is only
used to start the engine. After starting the engine, the heat from the engine is
used to ignite the gasoline/air mixture causing the explosions necessary to
maintain the combustion cycle.
Q. What is carbon in the engine
neck, and what causes it to form?
A. Do to the nature of the design
of a pulse-jet engine, there is a rapid change in temperature within a very
short distance. This rapid change combined with a high operating temperature
causes carbon deposits to form at two different locations: 1) at the "Heating
Point" in the Engine Neck just before the combustion chamber and 2) at the
"Cooling Point" in the exhaust tube just past where formulation is being
injected into the tube. The carbon is from the impurities normally found in the
formulation. Heat causes them to be "Baked Out" of the formulation and they
gradually build-up on the inner wall of the Engine Neck and Exhaust Tube.
Normally after 8-10 hours of fogging time, allow the engine to cool and inspect
the inside of the Engine Tube for carbon deposits. Remove the carbon deposits
using the clean-out brushes supplied with your machine. Be careful not to damage
the glow coil located in the engine neck during cleaning!
Q.
What flow rate setting do I use when spraying or fogging?
A. Each
different type of formulation you are attempting to spray or fog has its own
recommended flow rate. These flow rates adhere to the required EPA
Specifications for applying the correct amount of active ingredient per area to
be covered. Always follow the formulation manufacturer's application rates found
on the label of the product to be sprayed.
Q. What should the
fuel adjustment needle of the carburetor be set to?
A. Always make sure that you have exhausted all
other possible options before attempting to tamper with the carburetor settings.

to see a list of other possible
problems before tampering with the carburetor. All electric start thermal fog
machines have been produced after 1987. These carburetors require a slightly
different setting than the carburetor used on the pre-1987 version "hand pump
start" foggers. For all "electric start" (all are equipped with a push button
switch for air and ignition) thermal foggers except the Mistermax Model 2640,
the screw should be set to ½-5/8 of a turn open. The Mistermax Model 2640 is
equipped with two needle screws. The HIGH screw should be set to 1-1/2 turns
open, and the LOW should be set to 2 turns open. These settings tend to vary
depending on climate, temperature, altitude etc. The ideal carburetor setting is
the one that enables the engine to produce the highest pressure. To achieve best
results, it is recommended that a manometer or pressure gauge be used when
adjusting the carburetor needle screws.For all "hand pump start" machines,
except the Superfogger Model 2640, the needle screw should be set to 3/4 - 1
turn open. The Superfogger hand pump start machine was equipped with two
adjustment screws. The HIGH screw should be set to 1 turn open, and the LOW
screw should be set to ¾ of a turn open. These setting tend to vary depending on
climate, altitude, gasoline quality, etc. The ideal carburetor setting is the
one that enables the engine to produce the highest pressure. To achieve best
results, it is recommended that a manometer or pressure gauge be used when
adjusting the carburetor needle screws.
Q. Can I fog water-based
formulations with my thermal fogger?
A. Dyna-Fog produces thermal
foggers specifically designed for applying water based formulations (link to
Mister III literature here). However, models such as the Trailblazer, Patriot,
Golden Eagle, Superhawk and Blackhawk can be effectively used to fog water based
formulations at substantially lower than normal flow rates. Typically in these
machines you can only fog about 30%-40% of the maximum published flow rate using
a water-based formulation. For model and formulation base compatability, refer
to the thermal fogger section on the Product Line page.
Q. What
is the optimum droplet size needed to be produced to effectively kill
mosquitoes?
A. Many years of research, development and several
scientific studies on this subject reveal that a droplet of 10-20 microns (mass
median diameter) is the most efficient droplet size to produce for controlling
adult mosquitoes. Refer to the operation manual of your machine for the
recommended machine settings (blower pressure and flow rate) for the viscosity
of formulation being sprayed to achieve your desired droplet size.
Q. At what time of day and how frequently do I need to spray or
fog for mosquitoes?
A. You are spraying or fogging to kill the
adult female mosquitoes since it is only the female mosquitoes that bite. If at
all possible, you should spray or fog when the mosquitoes are most active.
Typically this tends to be in early morning or late evening when the wind
conditions are calm and the temperatures are not extremely hot or cold.
