Waste Disposal Chemical Disposal Improper chemical disposal can pollute the environment and cause health issues. Follow the disposal directions on the chemical-manufacturer’s label. Dispose of chemicals and containers in accordance to local/state/federal laws. Disposing of the Engine Oil Engine oil and hydraulic fluid are both pollutants to the environment. Dispose of used pollutants at a certified-recycling center or according to your state and local regulations.
Storage 2. Short-Term Storage 1. 2. Set sprayer-pump switch to the OFF position, stop the machine, move motion-control lever to the NEUTRAL position, shut off the engine, wait for all moving parts to stop, remove key, and engage parking brake. Empty the sprayer system by performing the following: A. Empty the sprayer tank. B. Start the machine and set sprayer-pump switch to the ON position C. Move the 3 boom spray-control valves to the ON position.
Troubleshooting Important: Ensure that the operator safety mechanisms for the machine are connected and in proper operating condition before you use the machine. When a problem occurs, do not overlook the simple causes. For example, starting problems could be caused by an empty fuel tank. The following table lists some of the common causes of trouble. Do not attempt to service or replace major engine items or any items that call for special timing of adjustments procedures (such as valves, governor, etc.).
Testing Alternator Output CAUTION Attach meter test leads to the AC output terminals (the yellow wires) in the connector before starting the engine. If the stator is grounded (damaged or worn) and the meter test leads contact the center DC output pin (the red wire) in the connector, arcing could occur, damaging the wiring. When checking the alternator components, preform the tests in the following sequence: 1. Disconnect stator wire harness from regulator/rectifier. 2.
Testing the DC Output Charging Wire Use this test to check the DC output charging wire circuit. If a wiring problem exists, you can correct it before testing regulator/rectifier. Leave stator wire harness disconnected from regulator-rectifier. Ignition switch must be in OFF position. 1. Turn the ignition switch to the 2. Disconnect stator wire harness from regulator/rectifier. 3. Insert red test lead into VΩ receptacle in meter. 4. Insert black test lead into COM receptacle. 5.
Note: If you find no or low alternator output , check that the regulator/rectifier is properly grounded, and that all electrical connections are clean and secure. If there is still no or low alternator output, replace the regulator/rectifier. Troubleshooting the Machine Problem The starter does not rotate the engine. Possible Cause 1. The battery does not have a full charge. 1. Charge the battery; refer to the Charging the Battery, and Jump Starting the Machine procedures. 2.
Problem The engine overheats. Possible Cause 1. The engine load is excessive. 1. Reduce the ground speed of the machine. 2. The oil level in the engine is low. 2. Add oil into the engine to the proper oil level. 3. Clean the cooling fins and the air passages. 3. The cooling fins and air passages for the engine are plugged with dirt or debris. The machine pulls to the left or the right (with steering control fully forward). The machine does not drive. The machine vibrates abnormally.
Problem There is no spray from the sprayer nozzles in the boom or the nozzles have poor output. The spray wand does not work. Possible Cause Corrective Action 1. The sprayer tank is empty. 1. Fill the sprayer tank. 2. The tank shutoff valve(s) is closed or partially closed. 3. The strainer is clogged or damaged. 4. The pump is clogged or damaged. 5. The nozzles are clogged. 6. The hoses are clogged, kinked, or damaged. 7. The boom spray-control valves are not in the ON position. 8.
