Do you have a question about the Fimco LG-40-4-3PT and is the answer not in the manual?

This document is the owner's manual for the FIMCO Model LG-40-4-3PT (5302941) sprayer, a 40-gallon, 12-volt, bolt-together, 3-point sprayer with a 4-nozzle boom. It provides comprehensive information for operating and maintaining the device, emphasizing safety, proper assembly, and effective use.

Function Description:

The FIMCO LG-40-4-3PT is designed for applying chemicals, fertilizers, and other liquids over a wide area. It attaches to a tractor's 3-point hitch, making it suitable for agricultural or large-scale landscaping tasks. The sprayer utilizes a 12-volt diaphragm pump to draw solution from the 40-gallon tank, pressurizing it for distribution through either a handgun or a 4-nozzle boom. The boom provides a 120-inch spray coverage, ideal for efficient application across fields or lawns. A pressure gauge allows for precise monitoring and adjustment of spray pressure, ensuring optimal application rates. The system includes a bypass (recirculation) line, which is crucial for pressure regulation and mixing chemicals within the tank. The handgun offers flexibility for spot spraying or areas where the boom cannot reach.

Usage Features:

The manual emphasizes a structured approach to using the sprayer, starting with assembly and testing.

Assembly: The sprayer is partially assembled upon arrival. Detailed, step-by-step instructions with illustrations are provided for completing the assembly, including attaching the frame, tank, boom support bars, and nozzle harness. Proper tightening of bolts and securing connections are highlighted.
Pre-Operation Check: Before actual spraying, users are instructed to test the sprayer with plain water to check for leaks and proper function without wasting expensive chemicals. This involves filling the tank halfway with water, connecting the lead wire to a fully charged 12-volt battery, and operating the boom and handgun.
Operation: The pumping system draws solution from the tank, through a strainer, and to the pump, which then forces the solution under pressure to the handgun or boom nozzles. The lead wire includes an On/Off switch ("-" for on, "O" for off). Pressure adjustment is achieved by turning the "ON/OFF" valve lever on the bypass line valve. Opening the bypass valve decreases pressure by recirculating solution back into the tank, while closing it increases pressure. When using the boom, it should be opened completely, and then pressure adjusted via the bypass valve if a lower pressure is desired.
Calibration: The manual stresses the importance of calibrating the sprayer for safe and efficient chemical application. This involves determining the proper speed (MPH) and pressure (PSI) based on chemical label instructions and tip charts. A method for determining travel speed by marking off distances (100, 200, 300 feet) and timing travel is provided.
Boom Nozzle Usage: Four key considerations for boom spraying are outlined: chemical mixture quantity, spray rate (gallons per acre), pressure (p.s.i.), and travel speed (mph). Users are directed to chemical labels for mixture ratios and tip charts for pressure and speed.
Safety Warnings: The manual includes warnings about the sprayer's weight when full, the need to read and understand the operator's manual, and a California Proposition 65 warning regarding cancer and reproductive harm. It also cautions against using the pump in explosive environments or with flammable/combustible fluids.

Maintenance Features:

Regular maintenance is crucial for prolonging the sprayer's life and ensuring optimal performance.

Post-Use Cleaning: After each use, the tank should be drained, and chemicals disposed of properly. The sprayer should then be filled halfway with clean water, and the pump run to flush the entire plumbing system and nozzles. A tank cleaner (like FIMCO Tank Neutralizer and Cleaner) or dish soap can be used for thorough cleaning, followed by another rinse with clean water.
Nozzle Cleaning: If boom or handgun nozzles require cleaning, they should be removed and soaked in warm soapy water. A soft-bristled brush or toothpick can be used, but metal objects should be avoided to prevent damage that could alter flow rate and spray distribution. Nozzles should be water-rinsed and dried before storage.
Strainer Maintenance: The strainer on the intake line should be periodically checked and cleaned.
Winter Storage: For end-of-season or long-term storage, the sprayer should be prepared by running RV antifreeze through the system. This lubricates internal parts, protects against corrosion, and prevents freezing. Any remaining antifreeze can be left in the tank. Before next use, the antifreeze should be rinsed out with clean water.
Troubleshooting: A detailed troubleshooting guide is provided for common issues such as the pump not running, low pressure/flow, pump surging, pump continuously running after discharge is shut off, and fuse blowing. This guide offers steps to diagnose problems like loose wiring, defective switches, clogged strainers, air leaks, and voltage issues.
Pump Maintenance: Instructions are given for checking the pressure switch (by bypassing it to see if the motor runs) and cleaning the check valve (by removing the pump head and cleaning the valve with hot, soapy water and a soft brush). These steps are critical for restoring pump prime and pressure.
Storage: The sprayer should be stored inside a building when not in use.

The manual emphasizes that proper care, adherence to instructions, and timely maintenance will ensure the longevity and effective operation of the FIMCO LG-40-4-3PT sprayer.
