4.1.7 Throttle Control: Located on the control console’s right side. The throttle is used to
control engine speed. Moving the throttle control forward will increase engine
speed and moving it to the rear will decrease engine speed.
4.1.8 “Off-Run” Switch (15 & 17 HP Kawasaki Manual Start only):
Located on the console. Turn key to the “Run” position to allow the engine to be
started. Turn key to the “Off” position to shut engine off.
4.1.9 Ignition Switch (17 HP Kawasaki Electric Start only):
Located on the control console. The ignition switch starts and stops 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).
When engine starts, release key.
Operator must have speed control lever in neutral and blade engagement
lever fully disengaged to start engine.
4.1.10 Park Brake Lever: Located on the right side of the unit above the hydraulic tank.
The brake lever engages the park 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.
Park brake must be disengaged to move speed control out of neutral or engine will
kill.
4.1.11 Fuel Shut-Off Valve: Installed in the fuel line midway between the tank and the
engine. The fuel shut-off valve is used to shut off the flow of fuel when parking
inside a building, during transportation to and from the job sites, and when the
machine will not be used for a few days.
Rotate valve 1/4 turn clockwise to shut fuel off. Rotate valve 1/4 turn counter-
clockwise to turn fuel on.
4.1.12 Drive Wheel Release Valves: Located on the top rear corner of the hydrostatic
pumps. Drive wheel release valves are use to release the hydro-static drive system
to allow the machine to be moved by hand without the engine running. Turn valves
one-half turn counterclockwise to release the drive system.
Turn clockwise to reset the drive system. Do Not over-tighten.
4.1.13 Cold Start Kit: (Manual start units only) Located on the right hand side of engine deck,
below the hydro control shield. The cold start kit is used to ease the starting of the
unit in cold weather or when the unit has not been operated for a period of time. The
cold start kit moves the idler pulley away from the pump belt releasing the tension on
the belt, which allows the engine to turn over with less resistance. See Section 4.3.2.
4.1.14 Tracking Adjustment Knob: Located on the right-hand side of the rear of the fuel
tank support. Can be adjusted so that machine will “track” straight ahead with
drive levers released.
4.2 Pre-Start
4.2.1 Fill fuel tank. 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.
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.
