FOREWORD
The application of insecticides is the predominant method by which man attempts to
control the size of insect populations. Due to environmental and economical reasons, it
is desirable to treat a given area with the least amount of insecticide that can be made
to be effective. The most efficient method is to break up the liquids into aerosols and
distribute these fine droplets over the target area. The small droplets stay suspended for
longer periods of time due to their size and are distributed more evenly, remaining
effective longer.
The term ULV is an abbreviation for Ultra-Low-Volume, the technology used to treat
areas with small amounts of chemical in an aerosol form. These chemicals are usually
in a more concentrated state than chemicals used in other methods of application.
For best results, the Dyna-Fog ULV aerosol generator model 274 should be operated
and maintained in compliance with this manual. Insecticides must be applied in
compliance with their label instructions.
WARNING
Read and thoroughly understand all information cautions and warnings on the
formulation label which may affect personal safety. Know any dangers of the
solution used and know what to do in case of an accident involving the solution.
Always use the appropriate safety e uipment and dress accordingly to the
chemical formulation which is being used.
DESCRIPTION
The Dyna-Fog model 274 ULV Aerosol Generator is designed to disperse
concentrated formulations at flow rates in the range of 0 to 120 oz./min. (0-3 48ml/min)
with droplet sizes less than 20 microns VMD (Volume-Median-Diameter) depending on
boom pressure, flow rate and viscosity of formulation. Maximum flow rate is dependent
upon pumping system being used.
This machine is to be vehicle or trailer mounted and is designed to be operated by the
driver of the vehicle using the remote control box.

WORKING PRINCIPLES
An 18 Horsepower, electric start, four-cycle gasoline engine with a flexible coupling on
its output shaft is used to drive a positive displacement rotary-blower. The air entering
the blower is first filtered through a large stainless steel filtering element. The blower
supplies air pressure to the nozzle. The air pressure is adjustable between 2-8 PSI
(0.14 - 0.69 Bar) by varying the engine speed and/or removing the air bleed orifice at
the boom. The formulation is delivered to each nozzle by means of a variable speed
positive displacement, rotary gear pump that draws the formulation from the tank,
through a filter and 3-way valve, and into each nozzle. The nozzle has six stationary fins
that create a swirling effect of the air mass as it leaves each nozzle. In the center of this
swirling air mass is a liquid supply spray tube. The spray tube directs the formulation
into the air mass where it is sheared into billions of tiny droplets and dispersed into the
atmosphere.
This unit is equipped with a flushing system that is controlled from the remote control
unit. The flushing liquid is conveyed to the nozzles in the same manner as the
formulation. The system must be lushed a ter each use. See following page the
Fluid Systems Diagram.
FLUID PUMPING SYSTEMS
There are two types of pumping systems available for the Maxi-Pro 2D:
1) Diaphragm Pump: This high volume pumping system utilizes a diaphragm type
pump with a needle valve on its outlet port to regulate liquid flow. Once the liquid flow
rate has been set, this is the flow rate that will be obtained when the operator activates
the SPRAY ON/OFF switch.
2) Rotary Gear-Pump: This pump is driven by a variable speed electric motor. All
functions are controlled from the remote control box. Once the pump has been set to
the desired flow rate, that flow rate will be obtained when the operator activates the
SPRAY ON/OFF switch. When adapted with the Dyna-Fog Radar Syncroflow feature,
the flow rate of the pump will automatically vary with vehicle speed.

ASSEMBLY INSTRUCTIONS
1) Uncrate the unit and remove all packing materials.
NOTE: It is a good idea to retain the original machine shipping carton for storage.
2) Place the remote control unit where it will not be damaged while the machine is
being installed.
3) Remove the machine from the shipping skid by removing the three lag screws
that retain the shipping brackets. Keep the brackets for mounting the machine to
your vehicle or trailer bed.
4) Check the lubricating oil level in both the engine and blower. Refer the engine
and blower sections of this manual and to the engine and blower manuals for the
correct filling procedure and add oil if necessary.
) Activate the dry charge storage battery according to the following instructions:
CHARGING THE BATTERY
DANGER: POISON
Batteries produce explosive gases. Keep sparks, flame and cigarettes away!
Ventilate when charging or using in an enclosed space.
The battery contains Sulfuric Acid, which causes severe burns. If acid contacts
eyes, skin or clothing, flush well with water. For contact with eyes, get immediate
medical attention.
Keep battery and acid away from children and other persons who may not be
aware of dangers involved.
A. Remove battery from its mounting and place on a stable workbench.
B. Remove vent caps from battery. Remove or destroy any sealing device which
may have been used to close or restrict the vent openings in the vent caps.
C. Fill each cell of the battery to the top of the separators with approved battery
electrolytes of 1.26 specific gravity.
NOTE: The temperature of the battery and electrolyte at time of filling should be above
60
