II. SAFETY PRECAUTIONS
WARNING
READ AND UNDERSTAND THESE SAFETY PRECAUTIONS
BEFORE OPERATING MACHINE.
1. ENGINE A ND FUEL: This machine uses gasoline as the fuel for the internal combustion
engine and all precautions commonly applying to this volatile fuel should be observed.
Exercise extreme caution to avoid spilling of gasoline. If spillage occurs, wipe if off and
allow evaporation time before starting the engine. DO NOT attempt to put fuel in the tank
while the machine is still running. Avoid smoking or open flame in area when handling
gasoline. Never run the unit indoors unless exhaust is vented to outside. These fumes
contain carbon monoxide which is colorless and odorless and can be fatal.
CAUTION:
DO NOT OPERATE ENGINE WITHOUT MUFFLER
DO NOT TOUCH HOT MUFFLER, CYLINDERS OR FINS
AS CONTACT MAY CAUSE BURNS.
Except for adjustment, DO NOT OPERATE THE ENGINE
IF AIR CLEANER OR COVER DIRECTLY OVER THE
CARBURETOR AIR INTAKE IS REMOVED.
DO NOT RUN THE UNIT IF THE BELT GUARD
IS REMOVED.
DO NOT TAMPER WITH GOVERNOR SPRINGS,
GOVERNOR LINKS OR OTHER PARTS WHICH MAY
INCREASE OR DECREASE THE GOVERNED ENGINE
SPEED.
2. ENGINE SP EED : (RPM) should be checked periodically to ensure that it is operating
correctly as engine speed effects the rate of air flow through the nozzle system which
controls droplet particle size. The correct engine speed should be 1800-3300 RPM.
3. BLOWER CASING: Blower casing and associated piping or accessories may become
hot enough to cause skin burns on contact.
A. DO NOT TOUCH WHEN HOT
B. Do not reach into any opening in the blower while it is operating, or while
subject to accidental starting.
C. Disconnect power before doing any work and avoid bypassing or
rendering inoperative any safety or protective devices.
D. DO NOT operate blower with inlet filter removed.
E. DO NOT stand in the discharge air blast from the nozzle.
F. Avoid extended exposure in close proximity to machinery which exceeds
safe noise levels.
(2)

II. SAFETY PRECAUTIONS (continued)
4. MACHINE D AMAGE: Never operate a machine after it has been damaged. A
damaged machine can be very hazardous.
5. WIND: Spraying during windy conditions is not usually practical because the
formulation will drift out of the intended area.
6. SAFETY EQUIPMENT: In addition to any safety equipment that may be required by
the type of formulation which is being used, the following items should be with each
vehicle which carries this machine during fogging operations:
A. Fire Extinguisher, chemical type rated for fuel fires.
B. First Aid Kit.
C. Eye Wash Solution.
D. Safety Glasses.
E. Container of Oil Dry Compound.
F. Gloves rated for high temperature.
G. Respirator adequate for formulation being used.
7. CHILDREN: Many spraying operations are performed in residential areas commonly at
dusk. This presents the operator with the problem of children who are attracted to the
noise and/or the mist being created. The possible hazard lies in the toxic effect of some
formulations, the severity of which depends upon the chemical used, mist density, and
the length of time of direct exposure. IT IS THE OPERATORS RESPONSIBILITY TO
DISCOURAGE ANYONE FROM PLAYING IN THE MIST OR BEING NEAR THE
MOVING VEHICLE.
8. FORMULATIO NS: Ensure that formulations are applied only in strict compliance with
formulation label as well as local, state, and federal regulations.
A. Always comply with any requirements for protective clothing, goggles,
gloves, facial masks, or respirators required on the formulation label.
B. DO NOT exceed the dosage set forth on the registration label of the
insecticide to be used.
C. Always store formulation in its original labeled container.
IN NO WAY IS IT TO BE CONSTRUED THAT THE CHEMICALS AND/OR DOSAGES ARE
THE RECOMMENDATION OF LONDON FOG, INC.
LONDON FOG INC., SHALL IN NO EVENT BE LIABLE FOR CONSEQUENTIAL DAMAGES
OR CONTINGENT LIABILITIES ARISING OUT OF THE FAILURE OF ANY AEROSOL
GENERATOR OR PART TO OPERATE PROPERLY.

III. ASSEMBLY / INSTALLATION
1. SHIPPING CONTAINER:
Remove the protective shipping container. Look for any hidden shipping damages and
if present, report it immediately to the carrier.
NOTE: It is a good idea to retain the original machine shipping
carton as well as its inner packing and blocking materials
for any future storage and/or shipment which may be
required.
2. REMOTE CONTROL UNITASSEMBLY:
A. Place the Remote Cab Control Unit where it will not be damaged while
machine is being prepared.
B. Lift the machine onto the vehicle with the discharge end of the machine
toward the rear of the vehicle.
C. Pass the Remote Cab Control Unit through an open window and locate
within reach of the person who will be operating the machine. If
permanent vehicle installation is desired, the remote control cable can be
passed through a small hole in the vehicle cab and then reconnected.
Make sure the small hole provides proper protection against wiring
damage and is re-sealed to prevent exhaust gases from entering inside
of the vehicle.
D. Using the most convenient routing, run the cab control to the outermost
electrical socket (blower end) on the flow control pump box. As the
machine is shipped, this will be the only unused socket. All the electrical
connectors on the machine are polarized to prevent incorrect
connections.
E. Orient the electrical plug on the cab control so that the electrical pin
locations match the mating pin receptacles in the socket and push the
plug firmly into the socket.
3. INSTALLATION:
A. Securely bolt the machine to the vehicle.
B. Loosen then nozzle swivel joints and orient the nozzle as required by the
formulation label. Usual set up is towards the rear and 45 degrees up.
Retighten joints.
C. Correct battery type is 24/24m series with marine style wing nut
terminals.

III. ASSEMBLY/INSTALLATION (continued)
4. BATTERY INSTALLATION:
A. New (Dry) Battery.
(i) Remove the battery from its box and place it on a stable work
surface in a well ventilated area.
(ii) Remove vent caps for battery. Remove or destroy any sealing
devise which may have been used to close or restrict the vent
openings in the caps.
(iii) Fill each cell of the battery to the top of the separators with
approved battery electrolyte of 1.265 specific gravity.
Temperature of battery and electrolyte at the time of filling should
be above 60 degrees F. (15 degrees C.)
CAUTION:
Never fill battery in machine as spills will damage finish on frame
and cause premature corrosion.
(iv) Charge 12 Volt battery at 30-40 amps until the acid temperature is
above 80 degrees F. (26 degrees C.) and the hydrometer reading
is 1.250 or higher.
Both temperature and hydrometer reading requirements must be
met.
(v) After charging the battery, check acid levels in all cells and fill
each cell with acid to the proper level.
(vi) Re-install vented caps.
(vii) Re-install the battery onto machine.
(viii) Connect positive (+) cable (leading from the starter solenoid which
is located on the engine) to the positive (+) post on the battery and
tighten bolt.
(ix) Connect the negative (-) cable to the negative (-) post on the
battery and tighten bolt.
NOTE: After battery has been initially serviced, only water
should be added to restore the liquid level in each
cell. Further addition of acid will cause battery
failure.
B. Wet (Sealed) Battery:
(i) When installing battery, connect the negative (-) cable last to
prevent sparking and shorting.
(ii) When disconnecting is required, remove negative (-) connection
first.
(iii) Reversed polarity can cause damage to the starting and charging
systems.

IV. SERVICE BEFORE START-UP
1. ENGINE
A. Gasoline -Service the engine with gas and oil. For best results, use only
regular unleaded gasoline with an octane rating of 87 or higher. In
countries using the research method, it should be 90 octane minimum. If
leaded gasoline is used, combustion chamber, cylinder head and spark
plug may require more frequent service (see SERVICE SCHEDULE,
section VIII).
B. Oil -Use high quality oil of API service class SF. Multi-Viscosity SAE 10W-
30 is recommended.
Make sure the machine is sitting level. Add the proper type oil through the oil fill tube to bring the
level up to, but not over, the "F" mark.
CAUTION:
DO NOT operate the engine with oil level below
the "L" mark or over the "F" mark.
2. BLOWER
A. Before starting machine, be sure the gearbox on the blower is filled to the
proper level with oil.
B. To fill the gearbox, remove the combination breather/knob on the top side
of the gear box and also remove the lower 1/4" pipe plug (called the
overflow hole) which is on the air filter side of the gear box.
USE SAE 40 NON-DETERGENT OIL.
Fill the gearbox up to the lower overflow hole. Replace the plug and the
breather.
DO NOT OVERFILL.
3. FORMULATIO N
Place formulation in the large black formulation tank. Always use a funnel and
strainer to avoid getting dirt or other contaminates in the tank.
USE ONLY FORMULATION THAT IS LABELED FOR THE INTENDED USE.
4. FLUSHING FLUID
Using a funnel with strainer or filter, place appropriate flushing fluid (for the
formulation being used) in the flushing tank.
