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 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 the 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 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 jobsite, and when parked
inside a building. The valve has three positions, each position made in 1/4
turn increments.
Valve handle down is the “OFF” position. Rotate valve handle 1/4 turn right
(from “Off” position) for fuel flow from the right tank. Rotate valve handle 1/4
turn left (from “Off” position) for fuel flow from the left tank.
4.1.10 Drive Wheel Release Valves: The drive wheel release valve levers are 1/4-
20x2 screws covered with a black vinyl grip located on the right front corner of
the 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.
Loosen both valves one turn to release drive system.
Tighten to reset system. DO NOT overtighten. DO NOT tow machine.
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.
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.
