4.1.8 Ignition Switch: Located on the lower center of 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).
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.)
4.1.9 Hour Meter: Located left on center of 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.
4.1.10 Fuel Shut-Off Valve: Located directly below center of console. 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 job site, and when parked inside a building. The
valve has three positions, each position made in 1/4 turn increments.
NOTE: The positions for the Kohler EFI units are different than all other units.
Reference the following table for the correct locations.

4.1.11 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. 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 Electronic Control Unit Malfunction Indicator: (Kohler EFI units only) The
electronic control unit (ECU) continuously monitors operation of the EFI system.
If a problem or fault within the system is detected, the malfunction indicator light
(MIL) is illuminated. The MIL is the red light located on the control console
between the key switch and the throttle controls. Follow the troubleshooting
steps outlined in the Kohler engine operator's manual if the MIL is illuminated.
4.1.13 Warning Buzzer (Kawasaki Liquid-Cooled Units Serial Nos. 370,000 and Higher
only): Located behind the seat on the right hand side. When the engine is
running and the buzzer emits a beep, the buzzer is warning signal the user that
the engine is overheating. Perform the following step.
1. Disengage the mower blade, and idle down the engine.
2. Look at the temperature gauge to determine if the 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.
