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 right side of console, next to cubby. 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.

Fuel Gauge: Located on the left fuel tank.

 

 

 

The fuel gauge monitors the amount of fuel in the left tank only. Use the fuel

 

from the right fuel tank first. When the right fuel tank is empty switch to the left

 

fuel tank. Fuel gauge will monitor the remaining fuel.

4.1.12

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. Unhook

 

seat latch and tilt seat up to gain access to pumps.

 

With a 7/16 wrench, turn both valves one turn counter-clockwise to release drive

 

system. Turn clockwise to reset system. DO NOT overtighten. DO NOT tow

 

machine.

 

 

 

4.1.13 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 right fuel tank to the

 

right of the hour meter. Follow the troubleshooting steps outlined in the Kohler

 

engine operator’s manual if the MIL is illuminated.

4.2 PRE-START

 

 

 

4.2.1

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 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.

 

 

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.
