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.
Electronic Control Unit Malfunction Indicator: (Kohler 26 HP 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.
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.
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" below the bottom of the filler neck to allow for fuel
expansion and prevent fuel spillage.
IMPORTANT: The fuel system for Kohler 26 HP EFI units must be purged of all
air prior to start up if the engine has been allowed to run out of gas or the system
has been disassembled. Turn the key to the "start" position for approximately 30
seconds. If engine does not start, wait 1 minute to allow starter to cool down
before attempting to start engine again.
Make sure you understand the controls, their locations, their functions, and their
safety requirements.
Refer to Maintenance, Section 5, and perform all the necessary inspection and
maintenance steps.
