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. Remove dirt and grime from the entire machine. 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 plastic lanyard clip is removed from the presence-control switch. 1. Insert the plastic lanyard clip is inserted into the presence-control switch. 2.
Problem The engine overheats. Possible Cause Corrective Action 1. The engine load is excessive. 1. Reduce the ground speed of the machine. 2. The oil level in the engine is low. 2.
