Brake must be engaged, motion control levers out (neutral lock position)
and PTO switch “OFF” to start engine. (It is not necessary for the operator to
be in the seat to start the engine.)
3.1.9 Hour Meter: Located on the right fuel tank. 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.
3.1.10 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.

3.1.11 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.
3.1.12 Drive Wheel Release Valves: Located on the top right 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 5/8 wrench, turn both valves one turn counter-clockwise to release drive
system. Turn clockwise to reset system. DO NOT overtighten. DO NOT tow
machine.
3.2 PRE-START
3.2.1 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.
3.2.2 Make sure you understand the controls, their locations, their functions, and their
safety requirements.
3.2.3 Refer to Maintenance, Section 4, and perform all the necessary inspection and
maintenance steps.
3.3 OPERATING INSTRUCTIONS
3.2.1 Operate units with the roll bar in the raised and locked position and use seat belt.
There is no rollover protection when the roll bar is down. If it is necessary to lower
roll bar do not wear the seat belt. Raise the roll bar as soon as clearance permits.
3.2.2 Open fuel shut-off valve (left or right tank).
