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 before moving speed control out of neutral or
engine will kill.
For manual start engines: The park brake must also be disengaged before the
PTO is engaged or the engine will kill.
4.1.12 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.
4.1.13 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 turn counterclockwise to release the drive system.
Turn clockwise to reset the drive system. Do Not over-tighten.
4.1.14 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.
4.1.15 Tracking Adjustment Knob
: Located on the right-hand side of the rear of the fuel
tank support. The tracking knob can be turned to adjust the drive so that
machine will “track” straight ahead with drive levers released.
4.2 Pre-Start
4.2.1 Refer to Maintenance and Adjustment Section 5 and perform all of the necessary
inspection and maintenance steps.
4.2.2 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.
Do not overfill fuel tank. Never fill the fuel tank so that the fuel level rises above
a level that is 1/2” (1.3 cm) below the bottom of the filler neck to allow for fuel
expansion and prevent fuel spillage.
4.2.3 Make sure you understand the controls, their locations, their functions, and their
safety requirements.
