Anleitung Zusammenfassung


Controls Motion Control Levers The motion control levers located on each side of the console control the forward and reverse motion of the machine. The levers control the flow of hydraulic oil from the hydrostatic pump to the drive wheel motor for each side. Moving the levers forward or backward turns the wheel on the same side forward or in reverse. Wheel speed is proportional to the amount the lever is moved. Moving the levers outward from the center position into the T-slot locks them in the neutral position (Figure 6). Choke Control Located on right fuel tank console. The choke is used to aid in starting a cold engine. Moving the choke lever forward will put the choke in the “ON” position and moving the choke lever to the rear, to the detent, will put the choke in the “OFF” position. Do Not run a warm engine with choke in the “ON” position. Throttle Control Located on right fuel tank console. The throttle is used to control engine speed. Moving the throttle lever forward will increase engine speed and moving the throttle lever to the rear will decrease engine speed. Moving the throttle forward into the detent is full throttle. Park Brake Lever Located on left side of unit, between the seat and the dummy tank. The brake lever engages a parking brake on the drive wheels. Pull the lever up and rearward to engage the brake. 18 Operation Push the lever forward and down to disengage the brake. The unit must be tied down and brake engaged when transporting. Ignition Switch Located on right fuel tank console. The ignition switch is used to start and stop the engine. The switch has three positions “OFF”, “ON” and “START”. Insert key into switch and rotate clockwise to the “ON” position. Rotate clockwise to the next position to engage the starter (key must be held against spring pressure in this position). Note: 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.) Hour Meter Located on the right fuel tank console. The hour meter is connected to a pressure switch installed in the engine block and it records the number of hours that the engine has run. If the ignition switch is left on without engine running, hour meter will not run. Note: This switch is not a low oil sensor and will not alert the operator if the engine oil is low. Fuel Shut-Off Valve Located in fuel line by fuel tank and fuel filter. The fuel shut-off valve is used to shut off the fuel when the machine will not be used for a few days, during transport to and from the jobsite, and when parked inside a building. Rotate the valve 1/4 turn clockwise to shut off fuel. Rotate the valve 1/4 turn counterclockwise to turn on fuel. Fuel Gauge Located at the rear of the right fuel tank. The fuel gauge monitors the amount of fuel in the right fuel tank only. The left tank does not hold fuel. Drive Wheel Release Valves Located on the top left 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. With a 5/8 inch wrench, turn both valves one turn counterclockwise to release drive system. Turn clockwise to reset system. Do Not overtighten. Do Not tow machine. PTO Engagement Switch Located on right fuel tank. Switch must be pulled out to the “ROTATE” position to engage the blades. Switch is pushed in to the “STOP” position to stop the blades. Hydraulic Lift Switch Located on right fuel tank console. The hydraulic lift switch is used to raise and lower the mower deck. Push the front portion of the hydraulic lift switch down to raise the mower deck to the desired height. Push the rear portion of the hydraulic lift switch down to lower the mower deck to the desired height. Pre-Start Fill fuel tanks. For best results use only clean, fresh regular grade unleaded gasoline with an octane rating of 87 or higher. Regular grade leaded gasoline may also be used; however, combustion chamber and cylinder head will require more frequent service. See Engine Owner’s Manual. Do Not add oil to gasoline. Do Not overfill fuel tank. Never fill the fuel tank so that the fuel level rises above a level that is 1/2 inch (13 mm) below the bottom of the filler neck to allow for fuel expansion and prevent fuel spillage. Make sure you understand the controls, their locations, their functions, and their safety requirements. 19 Operation Refer to the Maintenance section and perform all the necessary inspection and maintenance steps. Operating Instructions Raise the Rollover Protection System(ROPS) Important: Lower the roll bar only whenabsolutely necessary. 1. Remove the hairpin cotter pins and remove the two roll bar pins (Figure 5). 2. Raise the roll bar to the upright position and install the two pins and secure them with the hairpin cotter pins (Figure 5). Important: Always use the seat belt with theroll bar in the raised position. Ensure ...
