4.1.11 Drive Wheel Release Valves: Located on the top right front corner of hydrostatic pumps. Drive wheel release valves are used to release the hydrostatic drive system to allow the machine to be pushed without the engine running. Tilt seat up to gain access to pumps. With a 5/8 wrench, turn both valves one turn counter-clockwise to release drive system. Turn clockwise to reset system. DO NOT overtighten. DO NOT tow machine. 4.1.12 Coolant Temperature Gauge: Located at the front of the left fuel tank. The coolant temperature gauge monitors the temperature of the engine coolant. An engine overheating condition is indicated by the red area on the gauge and an alarm will sound (See Section 4.1.17). 4.1.13 Voltmeter: Located next to the Coolant Temperature Gauge at the front of the left fuel tank. The voltmeter measures the voltage output of the alternator. Both high and low voltages will potentially damage the battery. 4.1.15 Water in Fuel Light: Located on the right fuel tank. An illuminated water in fuel light signals water in the diesel fuel. Water should be drained from the fuel filter if the light is on. IMPORTANT: Water or other contaminants in fuel can severely damage fuel pump and/or other engine components. 4.1.16 Glow Plug Light: Located on the right fuel tank. The glow plug light comes on when the ignition switch is turned to the ON position. The glow plug light indicates the glow plugs are preheating the combustion chamber. Wait for the glow plug light to go out before starting the engine. 4.1.17 Warning Buzzer: Located behind the seat on the left hand side of the engine air deflector. The buzzer is a warning signal for the following circumstances: a) When the engine is not running and the ignition switch is turned to the ON position, the buzzer emits intermittent beeps. The intermittent beeps remind the user that the switch is ON and the hourmeter is running. A switch left ON could also drain the battery. b) When the engine is running and the buzzer emits a continuous beep, the buzzer is warning the user that the engine is overheating. Perform the following steps. 1. Disengage the mower blades, and idle down the engine. 2. Look at the temperature gauge to determine if temperature continues to increase. If it does, turn the unit off and allow the engine and engine components to cool. 3. Check the coolant level. If necessary fill with coolant as described in Section 5.1.2. 4. Remove any debris on or around the radiator that may restrict airflow. 5. Check to see if the water pump/alternator belt is intact. If belt is missing, do not run unit, as unit can overheat and damage the engine. See Engine Service Dealer. - 21 - c) When the engine is running and the buzzer emits intermittent beeps, the buzzer is warning the user that the engine oil pressure is low or the alternator is not charging. Perform the following steps. 1. Turn the unit off, allow the engine and engine components to cool. 2. Check the oil level and fill, if necessary, as described in Section 5.1.1. 3. Check for oil leaking from engine. If the engine is leaking, see Engine Service Dealer. 4. Check to see if the water pump/alternator belt is intact. If belt is present, there could be a charging problem, see Engine Service Dealer. If belt is missing, do not run, as unit can overheat and damage the engine. See Engine Service Dealer. 4.2 PRE-START 4.2.1 Fill fuel tanks. For best results use only clean, fresh diesel fuel, with a cetane rating of 40 higher. NOTE: Do not use kerosene or gasoline instead of diesel fuel. Failure to observe this caution will damage the engine. DO NOT add oil to fuel. DO NOT overfill fuel tank. Never fill the fuel tank so that the fuel level rises above a level that is 1/2” below the bottom of the filler neck to allow for fuel expansion and prevent fuel spillage. 4.2.2 Make sure you understand the controls, their locations, their functions, and their safety requirements. 4.2.3 Refer to Maintenance, Section 5, and perform all the necessary inspection and maintenance steps. 4.3 MOWING 4.3.1 Operate units with the roll bar in the raised and locked position and use seat belt. There is no rollover protection when the roll bar is down. If it is necessary to lower roll bar do not wear the seat belt. Raise the roll bar as soon as clearance permits. 4.3.2 Open fuel shut-off valve (left or right tank). 4.3.3 Starting Engine: a) Brake must be engaged, motion control levers out (neutral lock position) and PTO switch “OFF” to start engine. (It is not necessary for the operator to be in the seat to start the engine.) b) Ona warm engine, place the throttle in the “SLOW” position. On a cold engine (below 14° F (-10° C)), place the throttle in the “FAST” position. Note: Do not use fuel left over from summer. c) Turn the ignition switch to the “ON” position. The glow plug light will turn on. Wait for the glow plug light to turn off and turn the ignition switch to the “START” position. Release the switch as soon as the engine start...
