TABLE OF CONTENTS

Dear Valued Customer,
Congratulations on selecting Dyna-FogRand one of the finest and compact
Ultra-Low-Volume (ULV), machines in the world. The Mini-LiteTM is the newest in
the Dyna-FogRfamily of spraying equipment, and represents the latest in portable
spray technology. The Mini-LiteTM was developed to provide a powerful yet
affordable multi-purpose machine in a portable, lightweight package.
Trials have proven the Mini-Lite™’s effectiveness. Its simple operation and portable
design, combined with the ability to produce variable flow rates make the
Mini-LiteTM the most powerful machine of its type for dispensing liquids in the 20
micron range.
Backed by our Quality, Workmanship and more than 50 years of service, we are
confident that the Mini-LiteTM will be a valuable addition to any spraying program.
Thank you for choosing Dyna-FogR.
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 2990 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 EQUIPMENT AND DRESS
ACCORDINGLY TO THE CHEMICAL FORMULATION WHICH IS BEING USED.

MACHINE SPECIFICATIONS

The Mini-LiteTM is powered by a 40cc Tanaka 2-cycle gasoline engine. The
Mini-LiteTM is designed to offer a Low operational cost with a complete and compact
aerosol generator.
The engine and blower assembly are mounted on a lightweight steel tubular frame
with vibration isolators between them.
The Engine is used to belt drive a 3-stage High-Volume Blower. The engine has a
fixed but adjustable throttle control that allows to obtain the ideal working engine
operating speeds.
The blower supplies air thru a flexible hose to the boom and to the nozzle where the
air creates a “suction” on the formulation supply tube.
The suction in the formulation
supply tube causes liquid to be
drawn from the formulation tank,
thru a 3-way selector valve, onto
a metering valve, into a 2-way
solenoid valve and to the 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
(10-20 micron) and propelled
thru the air to their target.
This unit is equipped with a flushing system that is controlled from the manual 3-way
valve. The flushing liquid is conveyed to the nozzle in the same manner as the
formulation.
NOTE: The system must be flushed after each use.

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 screws that
retain the shipping brackets. Keep the brackets for mounting the machine to
your Golf cart, vehicle or trailer bed.
4) Activate the dry charge storage battery according to the following instructions:
CHARGING THE BATTERY
Battery: 12 V, 7.5 AH, sealed (Nonspillable) maintenance-free rechargeable battery
Caution:
Contains toxic material (lead) and corrosive fluid (acid) – Keep away from children
Flush with water at once if contaminated with electrolyte (acid)
Do not charge in gas tight container
Do not short the battery terminals
Do not incinerate
Unlawful to discard in landfill
Recycle with automotive battery scrap at an EPA or other registered facility
Automatic Sealed Lead Acid Battery Charger
This charger is designed to fully charge a battery and maintain it at the proper storage
voltage without the damaging effects caused by trickle chargers.
The length of time required to fully charge a battery is dependant on the state of
discharge. Discharging a battery deeply is not recommended, nor should they be
stored in a discharged state for very long. This results in a condition known as
“sulphation” which is effectively a permanent reduction in energy storage capacity.
CAUTION
Do not attach leads to battery in reverse polarity or short leads while charger is
plugged in.

ASSEMBLY INSTRUCTIONS

1. Remove the machine from the skid and lift the machine onto the vehicle with
the discharge end of the machine toward the rear of the vehicle.
2. Pass the remote control unit through an open window (if any) and locate it
within reach of the person operating the machine. If permanent vehicle
installation is desired, the remote control cable can be fed through a clearance
hole in the vehicle chassis and then reconnected. When drilling clearance
holes, ensure that all sharp edges are removed and covered to prevent
premature wearing of the remote cable. When routing the cable to the vehicle
cab, do not allow the cable to be exposed to any sharp edges. Avoid sharp
bends when routing the cable. Once the cable has been routed to the cab,
reseal all drilled openings to prevent moisture and/or exhaust gases from
entering the cab.
3. Using the (2) hold-down brackets used for mounting the machine to the
shipping skid, securely mount the machine to the bed of the vehicle (see
diagram below). Depending on the type of bed surface, it may be necessary to
use additional mounting hardware to secure the machine. Dyna-Fog® offers
an ATV/Wheel mounting kit to fit a wide range of mounting surfaces.
