The Right Sprayer For The Job Before buying a sprayer, make certain that the sprayer you select is the best choice for the job you need to do. Some sprayers can be used for a variety of tasks, but many are designed specifically with a particular job in mind. All sprayers, regardless of type or size, should be carefully cleaned and maintained after each use. Cleaning Your Sprayer • • • Do not use flammable materials either for spraying or for cleaning your sprayer. Heat can cause the chemical in the sprayer to ignite or explode resulting in injury or death. Note: Dispose of any chemicals according to manufacturer's instructions. • Release pressure (following de-pressurizing steps provided in instruction book), remove the pump, and empty the sprayer. • Rinse the tank thoroughly with water only to remove tank residue, empty and refill with water. • Using water, follow the filling, pressurizing, and spraying instructions, but pump the unit no more than 8-10 strokes. Open the shut-off lever and allow water to run through the discharge assembly. Release pressure, remove the pump and empty the sprayer. Regular Maintenance Is Important, Too • • Periodically remove the nozzle assembly and extension from the shut-off. With the shut-off pointing upward, place 6-8 drops of light oil into opening and activate lever. Periodically lubricate the pump by dropping 10 to 12 drops of light oil down the pump rod through the opening in the cover. Trouble-Free Spraying If used and maintained properly, your sprayer will function efficiently and reliably. Problems that occur with the sprayer are almost invariably the result of foreign particles caught in parts of the assembly; most commonly grass or dirt. Here are a few helpful hints to correct and prevent problems and keep your sprayer trouble-free. Note: Before proceeding with the hints listed below, make sure pressure is not built up inside the tank, if so, it must be released before taking the shut-off apart. Unscrew cover/cap of tank and listen for air escaping from the cover. A. For products with poly shut-offs, simply clean nozzle and refer to steps 1 through 5. B. For products with zinc and brass shut-offs, simply clean nozzle and refer to steps 3 through 5. 1. If nothing comes out of the nozzle when the shut-off lever is squeezed open, remove the lever by gently, but firmly twisting back and forth and pulling up. Turn the lever around and it is now a tool to remove the retainer. Fit the four small extensions into the four oval holes at the top of the retainer. Rotate one-quarter turn counter-clockwise. This will release spring pressure in the valve if the retainer was too tight and allow proper chemical flow. Replace the lever by gliding front under the button on top of the retainer, push down and snap into place. 2. If the problem persists, remove the lever and completely unscrew the retainer by turning it counter-clockwise. Lift the retainer from its socket and tap the socket upside down to free the diaphragm. Remove any foreign particles by wiping all parts with a clean cloth. 3. Another source of clogging could be grass in the nozzle. Unscrew the nozzle cap and remove grass or dirt particles from nozzle holes. 4. To prevent debris from accumulating on the pump mechanism, avoid placing it in the grass or on the ground when filling the tank. Make sure the surface of the pump is clean before replacing in tank. Check for debris under rubber valve bottom at the bottom of the pump by lifting valve bottom and cleaning any accumulated matter from holes or underside of pump. 5. Failing to lubricate the pump mechanism could cause difficulty in pressurizing the unit. A dry pump can be remedied by applying a few drops of oil. Rules For Safe Spraying Before assembling and operating your sprayer, read all instructions thoroughly, When working with equipment under pressure, safety precautions should always be carefully observed, including the following: • • • • • • • • • Never spray flammable materials. Flammable materials can ignite causing serious injury or death. Always read chemical label before filling the sprayer as some chemicals may be hazardous when used with the sprayer. Do not leave pressurized sprayer in the hot sun or near any heat source. Heat can cause pressure to build up causing sprayer to ignite or explode resulting in injury or death. Do not store or leave any solution in the tank after use. Always wear goggles, gloves, a long-sleeve shirt, long pants, and full foot protection when spraying. Never use any tool to remove the pump if there is pressure in the sprayer. To avoid possible injury, avoid standing with your face or body directly over the top of the tank when pumping or loosening the pump. NEVER pressurize the sprayer by any means other than the original pump. Over pressurizing can cause sprayer to explode resulting in injury or death. Do not attempt to modify or repair your sprayer except with the original manufacturer's parts. Warning Read All Warnings and Precautions Carefully! When activated, most sprayers contain chemicals under pressure. For the safety of the sprayer operator and everyone in the area of spraying, be sure you read and understand all warnings and safety precautions included in the operating instructions or posted on the equipment.
