Specications Important: In order to accurately record the volume, be sure all three boom valves are turned on. This sprayer cannot accurately record the tank volume when any of the boom valves are on or off. Note: Specifications and design are subject to change without notice. • Flowmeter Calibration Alternates the display of the flowmeter calibration value and the recorded calibration volume at 3 second intervals. Use this setting to adjust the flowmeter calibration.
Operation Check the Tire Pressure Note: Determine the left and right sides of the machine from the normal operating position. Check the tire pressure every 8 hours or daily to ensure proper levels. Fill the tires to 18 psi (124 kPa). Also, check the tires for wear or damage. Think Safety First Add Fuel Please carefully read all of the safety instructions and decals in the safety section. Knowing this information could help you or bystanders avoid injury.
In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. • Always place gasoline containers on the ground away from your vehicle before filling. • Do not fill gasoline containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge. Figure 21 1.
New Sprayer Break-In before taking the sprayer out for the day. Your supervisor may want you to check other items on a daily basis, so ask what your responsibilities are. To provide proper performance and long sprayer life, follow these guidelines for the first 100 operating hours: • Check the fluid and engine oil levels regularly and be alert for indications of overheating in any component of the sprayer. • After starting a cold engine, let it warm up for about 15 seconds before accelerating.
The Multi-Pro Sprayer has been specifically designed to have high durability in order to give it the long sprayer life you need. Different materials have been chosen for specific reasons at different locations on your sprayer to meet this goal. Unfortunately there is no single material which is perfect for all foreseeable applications. Some chemicals are more aggressive than others and each chemical interacts differently with various materials. Some consistencies (e.g.
To open the fresh water tank spigot, turn the lever on the spigot. Figure 23 1. Tank cover 2. Anti-siphon ll receptacle 4. Add 3/4 of the required water to the spray tank using the anti-siphon fill receptacle. Important: Always use fresh clean water in the spray tank. Do not pour concentrate into an empty tank.

Set the master spray lever to the Off position. 3. Set the individual boom levers, as needed, to the On positions. 4. Drive to the location where you will be spraying. 5.
• You will obtain better results if the sprayer is moving when you turn the booms on. • Watch for changes in the application rate that may indicate that your speed has changed beyond the range of the nozzles or there is a problem with the spray system. Figure 25 Cleaning the Sprayer 1. Important: You must always empty and clean the sprayer immediately after each use. Failure to do so may cause the chemicals to dry or thicken in the lines, clogging the pump and other components.
9. Allow all of the water in the tank to spray out though the nozzles. 10. Check the nozzles to ensure that they are all spraying correctly. 11. Set the master spray lever to the Off position, set the pump switch to the Off position, and stop the engine. 12. Repeat steps 3 through 11 at least 2 more times to ensure that the spray system is fully cleaned. 13. Clean the strainer; refer to Cleaning the Suction Strainer inCleaning, page 56.
