4.1.4 Choke Control: (All units except Kohler 26 HP EFI) Located at lower center of
console (right side of ignition switch). Choke is used to aid in starting a cold
engine. The choke control is pulled out to be in the " ON " position and pushed in
to be in the " OFF " position. DO NOT run a warm engine with choke in the "ON"
position.
4.1.5 Throttle Control: Located on console just right of center.
Throttle is used to control engine speed. Moving throttle lever forward will increase
engine speed and moving throttle lever to the rear will decrease engine speed.
4.1.6 Brake Lever: Located on left side of unit, just to the front of the console. The brake
lever engages a parking brake on the drive wheels.
Pull the lever up and rearward to engage the brake.
Push the lever forward and down to disengage the brake.
When parking on a steep slope, the wheels must be chocked or blocked in addition
to the brake being engaged. The unit must be tied down and brake engaged
when transporting.
4.1.7 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).
Operator must be in seat with brake engaged, motion control levers out
(neutral lock position) and blade engagement switch "OFF" to start engine.
4.1.8 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.
4.1.9 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 26 HP EFI units are different than all other units.

also be used; however, combustion chamber and cylinder head will require more
frequent service. See Engine Owner's Manual.
