system:
1. The operator must be on the seat when testing the seat
switch.
2. Set both steering control levers in the park brake position.
3. Start the engine and allow it to warm up to operating
temperature.
4. With the deck clutch switch down and the steering
control levers in the park brake position, slowly raise off
of the seat. The engine should continue to run.
5. With the deck clutch switch up and/or the steering control
levers in the neutral position, slowly raise off of the seat.
The engine should stop.
6. If the engine fails to stop when the deck clutch switch is
up or one or both of the steering control levers is up and
the operator is off the seat, check the function of the seat
switch. If the seat switch is not operating properly (is not
opening or closing) and if the cause can not be
determined, replace the seat switch.
If the problem cannot be located, contact your Hustler
Dealer.
WARNING
The safety interlock system should always function per
steps 4 and 5. If it does not function properly, it should be
corrected immediately. Do not operate machine without a
properly functioning seat safety switch.

Engine Starting

The Hustler ® Diesel Z safety start interlock system is designed
to protect the operator and others from accidental injury due to
unintentional engine starting. The engine starting motor will not
engage until:
A. Steering control levers are in the park brake position.
REV F
B. Deck clutch switch is in the down (OFF) position.
The safety interlock system must not be disconnected or
bypassed. Doing so could cause the machine to operate
unexpectedly resulting in personal injury.
NOTE: The operator's seat is equipped with a separate
safety switch. If for any reason the operator should become
unseated when the brake switches are disengaged or the deck
clutch switch is engaged the engine will stop.
The following steps are the correct procedures for starting the
engine. If difficulty is encountered, contact the Hustler
in your area.
1. Before starting mower each day, perform daily pre-
operation checking.
2. Make sure the control levers are in the park brake
position and deck clutch switch is disengaged. Only start
the engine from the operator's position.
3. Set throttle at approximately 1/2 open position.
4. Insert key in ignition switch and rotate it to the "PRE-
HEAT/RUN" position. It takes two seconds before the
glo-plug light will come on. Wait for the glo-plug light to
go off (6 seconds) before rotating the key to the
"START" position. This is necessary only when the
temperature is below 50°F (10°C). This operation is not
necessary when restarting a warm engine.
Shown in the chart are the standard preheating times for
various temperatures. This operation, however, is not
required when the engine is warmed up.
Failure to follow these recommendations can lead to
premature failure of the starter motor and the fuel
shut-off solenoid.
IMPORTANT: Ether, or other starting fluids, must
never be used as a starting aid with this engine. War-
®
ranty will be denied when engine damage results from
such use..

5. Rotate ignition switch key full clockwise to engage
starting motor. Release key when engine starts.
IMPORTANT: The engine starter should not be operated
for periods longer than 30 seconds at a time. An interval
of at least two minutes should be allowed between such
cranking periods to protect the starter from overheating
and burn-out.
6. Perform test to make sure safety start interlock system is
operating properly. Refer to Safety start interlock system
section.
7. As soon as engine begins to run, check to make certain
the oil warning light is off. If not, stop engine
immediately and check for the cause.
