Operation Operation Note: Deter mine the left and right sides of the machine from the nor mal operating position. Controls Motion Control Levers The motion control lev ers , located on eac h side of the top console , control the forward and rev erse motion of the machine .
Operation The brake lever eng ages a parking brake on the driv e wheels . Note: The LCD indicator appears in the message display on the front console when the park brake is engag ed (see Figure 5 and Figure 7). T o engag e the brak e, pull the lev er rearw ard and to the right to position into the engag ed position.
Operation The fuel gauge monitors the amount of fuel in the tank. Drive Wheel Release V alves Located on the right front cor ner of the hy drostatic pumps . Driv e wheel release valv es are used to release the hy drostatic dri ve system to allow the mac hine to be mov ed b y hand without the engine r unning .
Operation 3. Push in (down) on the PTO switch to the “disengag e” position. 4. Place the throttle midway betw een the “SLO W” and “F AST” positions . 5. On a cold engine , push the chok e lev er forward into the “ON” position (ex cept Kohler EFI units).
Operation Driving the Machine CAUTION Machine can spin ver y rapidly by positioning one lever too much ahead of the other . Operator may lose control of the machine, which may cause damage to the machine or injur y . • Use caution when making tur ns.
Operation Figure 10 T o turn left or right, release pressure on the motion control lever toward the desired turn direction. 3.
