I. SPECIFICATIONS TYPE: U.L.V. (Ultra Low Volume) Cold fog aerosol generator. Vehicle or trailer mountable - non-thermal, ENGINE: Single cylinder Kohler with overhead valve, 4-cycle, gasoline engine. 9 h.p., 12 V. Fuel Consumption - regular or no lead automotive 1 gal/hr. Electric start with alternator, pressure lubrication.. BLOWER: Rotary lobe, cast iron, Dresser Roots. 181 CFM @ 3600 RPM, 6 p.s.i. max.
II. SAFETY PRECAUTIONS WARNING READ AND UNDERSTAND THESE SAFETY PRECAUTIONS BEFORE OPERATING MACHINE. 1. ENGINE AND 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.
II. SAFETY PRECAUTIONS (continued) 4. MACHINE DAMAGE: 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.
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: 2. 3. 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. REMOTE CONTROL UNIT ASSEMBLY: A. Place the Remote Cab Control Unit where it will not be damaged while machine is being prepared.
III. ASSEMBLY/INSTALLATION (continued) 4. BATTERY INSTALLATION: A. Wet (Sealed) Battery: (i) (ii) (iii) When installing battery, connect the negative (-) cable last to prevent sparking and shorting. When disconnecting is required, remove negative (-) connection first. 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.
V. PRE-START CHECKLIST SEE SECTION # All safety equipment is in place _____ I. Remote control panel in place _____ IV. Battery is secure in place _____ IV. Sufficient gasoline in gas tank _____ IV. Oil in engine at proper level _____ IV. Oil in blower at proper level _____ IV. All fluid lines tight and connected _____ IV. Sufficient formulation in tank _____ IV. Flushing fluid in flush tank _____ IV. Flow rate is calibrated _____ VII. Nozzle is aimed correctly _____ III.
VI. START-UP / SHUTDOWN 1. Be sure to complete the service before start-up: pre-start check list and all safety precautions, before starting machine. 2. START Move the engine ignition switch (on the control panel, see figure 2 - section VII) to the "ON" position. A. On a cold engine, turn key to "ON" position, turn cab control power switch to "ON" position, push the start and move the choke lever to full choke. As soon as the engine starts to fire, release the choke lever.
VII. OPERATION Read this complete OPERATION section and the section on SAFETY PRECAUTIONS before starting the machine. For first time operation the sections on INSTALLATION, SERVICE BEFORE START UP, and PRESTART CHECKLIST must be performed before proceeding with operation. When operating this machine for the first time, move to an uncongested and well ventilated work area in an open area away from flammable materials. WARNING READ THE SECTION ON SAFETY PRECAUTIONS BEFORE PREPARING TO DISPENSE FORMULATION.
VII. 2. OPERATION (continued) C. To Stop spraying, turn the spray switch to the OFF position. D. When the spraying operation is complete, the unit must be flushed in accordance with FLUSHING SYSTEM section of this manual. SETTING THE FLOW RATE NOTE: Since this machine may be used with various materials, the machines are shipped with the flow rate set at approximately 4.0 fl. oz/min. A. Loosen the two latches holding the flow control pump box shut and open the pump box cover. B.
VII. OPERATION (Continued) D. With the engine running, turn the spray switch "ON" for a measured amount of time using a stop watch. Record the flow rate and pump setting for future reference. E. Loosen the pump pointer locking plate by loosing the two knurled nuts and adjust pointer as needed. Tighten the two knurled nuts. F. Refill the graduated cylinder and repeat steps D and E until the desired flow rate is obtained. G. Replace the fluid line to the formulation tank.
III.
IX. MAINTENANCE 1. AIR PRESSURE The nozzle air pressure can be checked at the gauge located on the flow control pump box. Pressure should be approximately 6 psi. Air pressure is controlled mainly by engine speed which should be 2700-3000 RPM. 2. A. Engine speed not correct - see Engine Trouble Shooting, section X and Governor Maintenance, Section IV. B. Engine speed correct - see Air Pump Trouble Shooting, section X.
IX. MAINTENANCE (continued) 6. B. When servicing drive end bearings, use a premium grade, petroleum base grease with high temperature and moisture resistance and good mechanical stability. Using a pressure gun, force new lubricant into each drive end bearing housing until traces of grease comes out of the relief fitting. C.
IX. MAINTENANCE (continued) C. Remove the dipstick and wipe oil off. Reinsert the dipstick and push it all the way down into tube. Remove the dipstick and check the level. D. Add the proper type of oil if the level is low. Bring the level up to, but not over, the "F" mark on the dipstick before adding more oil. CAUTION: DO NOT operate the engine with the oil level below "L" mark or over "F" mark. 9. ENGINE OIL CHANGE A.
IX. MAINTENANCE (continued) 10. ENGINE OIL FILTER (if present) A. Change the engine oil filter at "each" or "every other" oil change depending on operating conditions A genuine Kohler oil filter is recommended. (i) (ii) (iii) B. 11. Drain crankcase oil, then remove old filter. Before installing replacement filter apply a thin coating of oil on the surface of the rubber seal. Turn filter clockwise until rubber seal contacts the filter adapter, then tighten filter and additional 1/2 turn.
IX. MAINTENANCE (continued) (filter location may vary) 14. C. Rinse the precleaner thoroughly until all traces of detergent are eliminated. Squeeze out excess water (do not wring). Air dry. D. Saturate precleaner in clean, fresh engine oil and squeeze out excess oil. E. Reinstall precleaner over paper element. ENGINE PAPER AIR FILTER Every 100 operating hours (more often under extremely dusty or dirty conditions) check the paper element. Clean or replace the element as necessary. A.
IX. MAINTENANCE (continued) D. 15. Reinstall the paper element, precleaner, element cover, element cover seals, air cleaner cover, and wing nut. Tighten wing nut 1/2 to 1 full turn after the nut contacts cover. Do not over tighten. ENGINE FUEL FILTER This filter is located on the gas line between the engine and the gas tank. Clean as needed. 16. ENGINE SPARK PLUGS Every 200 operating hours remove the spark plugs, check condition and reset gaps, or replace with new plugs as follows: 17. A.
IX. MAINTENANCE (continued) 20. CHECK/SET GOVERNOR NOT REQUIRED 21. PULSATION DAMPER (located inside pump box) The piston type metering pump tends to deliver a slightly pulsating flow of insecticide. For best aerosol particle size, a more even (non-pulsating) flow is desirable. A small air chamber type pulsation damper is located in the metering pump box assembly, between the pump and the aerosol discharge nozzle. It is a white nylon assembly with an air dome that can be unscrewed by hand for inspection.

IX. PREPARATION FOR STORAGE 1. GENERAL If the unit is to be out of service for two or more months clean the entire machine with soapy water. Rinse and dry thoroughly. 2. BLOWER When a blower is taken out service it may require internal protection against rusting or corrosion. The need for such protection must be a matter of judgment based on existing conditions as well as length of downtime. Under favorable conditions, protection will probably not be needed if shut-down is not longer than a month.
