If machine is equipped with a xed ROPS,
always wear seatbelt.
If machine is equipped with a foldable
ROPS, always wear seatbelt when ROPS is
deployed.
Be certain that the seatbelt can be released
quickly if the machine is driven or rolls into
ponds or water.
Check carefully for overhead clearances
such as, branches, doorways, or electrical
wires, before driving under any objects and
do not contact them.
STOPPING THE ENGINE
Set the throttle at
1
/3 open. Allow engine to
idle at this setting for several minutes, then
move the throttle to slow idle.
Move ignition switch to “OFF” position (up-
right) and remove key.
Always remove key from ignition
switch when leaving unit unattended
or when not in use.
Emergency shutdown of engine:
If the engine does not stop running with the
throttle at slow idle and the starter switch in the
“OFF” position, the following procedure will
stop the engine.
Unplug the wires from the fuel shut-off sole-
noid (item 30, page 31).
Push the engine stop lever forward toward
the radiator (refer to the Engine Manual’s il-
lustration showing the location of the engine
stop lever).
It is important that the operator be familiar
with where the parts are located on the en-
gine.
MOVING UNIT WITHOUT POWER
The hydro pumps are equipped with a dump
valve (Refer to Fig. 3) that allows the unit to be
moved without power by deactivating the pump.
With the dump valve lever in normal operat-
ing position the uid in the pump will make it
dif cult to move the unit (even with the steer-
ing levers in neutral position). The dump valve
is located on the bottom toward the right front
of each hydro pump. Activate the dump valve
by rotating counter-clockwise with a .625 inch
wrench. Rotate one revolution. When BOTH
hydro pumps are deactivated the unit becomes
“freewheeling” allowing it to be moved. Before
the hydro pumps become operational the dump
valves must be returned to their normal operat-
ing position. Do not tighten above 120 in.lbs.
(10 ft.lbs.) maximum.
