  • Page 18: Starting The Engine

    STARTING THE ENGINE CHOKE ENGINE: Move engine choke control to position lever in "choke" position (pulling the control rod). NOTE: This should fully close choke on carburetor. Note: The manual choke is provided for cold starting of the engine. Once the engine has been allowed to warm-up, choking the engine should not be needed for restarting.

  • Page 19: Liquid Flowability Measurement

    MEASURING LIQUID FLOWABILITY (VISCOSITY) In order to achieve consistent results in generating aerosols with a volume-median- diameter (VMD) in the sub 20 micron range, several variables must be kept under control at the same time. The ability of an aerosol generator to consistently break up a liquid into appropriate sized droplets depends on (3) key elements: The available energy flow (air flow) through the nozzle is governed by the blower speed.
  • Page 20 To measure the flow ability (viscosity) of your formulation: 1. Place a sample of the formulation liquid to be dispensed in the relative viscosity meter provided with the machine such that the liquid level is above the top line. 2. Hold the meter vertical and allow the liquid to flow through the brass orifice at the outlet end of the meter into an appropriate container.

  • Page 23: Syncroflow Section

    SYNCROFLOW SYSTEM When equipped, the Curtis Syncroflow System allows the dispensing of formulation to be either a constant flow ("manual") regardless of vehicle speed, or a variable flow ("syncroflow") which is correlated to vary proportionately with vehicle speeds from 0 to 20 m.p.h.
  • Page 24 Adjust the knob for the rate of flow specified by the formulation label that pertains to your vehicle speed. Example: If a formulation label calls for an output of 3 oz at 5 MPH (89 ml at 8 Km/h), 6 oz at 10 MPH (177 ml at 16 Km/h), 9 oz at 15 MPH (266 ml at 24KM/h), and 12 oz at 20 MPH (335 ml at 32 Km/h), you may set the flow rate at any of these speeds.

  • Page 25: Maintenance

    PREVENTIVE MAINTENANCE NOTE: A successful maintenance program begins after the first use of the machine and not after the machine has ceased to function. PREVENTIVE MAINTENANCE: Occasionally inspect mounting hardware to ensure that fasteners are tight. Loose hardware can cause excessive vibration leading to major failure of components.

  • Page 26: Maintenance Schedule

    MAINTENANCE SCHEDULE TABLE 5 NOTE: Change oil more often when operating in high ambient temperatures. Clean air filters more often under dusty conditions or when airborne debris is present. See engine and blower manuals.

  • Page 27: Formulation/Flush Solenoid Valve

    3-WAY SOLENOID VALVE (FORMULATION/FLUSH) The corrosion resistant 3-way solenoid valve is located under the Nozzle Boom assembly (close to blower brackets) and is used as a selector to route either formulation (spray) or flushing solution (flush) from their respective tanks to the nozzles. This is done by placing the "MODE"...
  • Page 28 FLUSHING SYSTEM The system must be flushed after each use to protect the equipment from the corrosive materials in the formulation. CAUTION Never handle any parts that come in contact with formulation until the unit has been thoroughly flush with isopropyl alcohol or other recommended flushing agent.

  • Page 29: Formulation Filter

    FORMULATION FILTER The system is equipped with an in line low profile filter located at the formulation tank standpipe. This filter is to prevent any foreign matter from entering the 3-way solenoid valve and the nozzle system. Located inside the filter housing is a fine mesh stainless steel screen and an Atlas gasket seal.

  • Page 30: Blower Filter

    FILTER - SILENCER (Rotary Blower) General: The air blower filter - silencer is mounted on the air blower. Dirt and other foreign particles are filtered from the incoming air by means of the reusable stainless element. The design is such that it partially silences the air also. Note: DO NOT run the machine without this filter silencer assembly, as this would cause serious damage to the blower unit.

  • Page 31: Nozzles

    ULV NOZZLE ASSEMBLY The design of the ULV Nozzle is such that it should require little maintenance if the machine is properly flushed after each use. However, if it becomes necessary to clean the entire Nozzle Assembly, refer to steps 1-7. To inspect the inside of the Nozzle it is not necessary to remove the entire Nozzle Assembly from the machine.
  • Page 32 IMPORTANT If for any reason it becomes necessary to have to remove the spray tube from the nozzle cone, care must be taken to hold dimension “A” when reassembling. Dimension “A” is the distance from the end of the spray tube to the front face of the nozzle cone. Be careful not to damage the output end of the spray tube when disassembling.

  • Page 33: 3-Way Solenoid Valve
