WARNING: For safe operation, do not attempt to
override or bypass either of these systems. If either
system fails to function, it should be repaired before
using the unit.
Engine starting
The 3500/3700 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:
1. The operator is seated
2. HST foot pedals are released (neutral position)
3. PTO lever is in the disengaged “OFF” position
4. The master brake pedal is depressed or park brake
lever is engaged.
NOTE: For safe operation the front mounted equipment
should be lowered prior to starting the engine.
WARNING: Never attempt to start the engine while
standing beside the unit. Always sit in the seat
when starting the engine.
IMPORTANT: Do not engage the starter continuously for
more than 30 seconds, doing so may cause starter failure. An
interval of at least two minutes should be allowed between
such cranking periods to protect the starter from overheating
and burn-out.
WARNING: 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 is disengaged or the PTO is engaged
the engine will stop.
The following steps are the correct procedures for starting
the engine. If difficulty is encountered, contact the Hustler
Dealer in your area.
NOTICE: Ether, or other starting fluids, must never be used
as a starting aid with this engine. Warranty will be denied
when engine damage results from such use.
Warm weather starting
To start a cold engine in warm weather or to start an engine
that is warm;
1. Depress the master brake pedal fully and move the
PTO and transmission selector levers to the off and
neutral positions.
2. Move the hand throttle forward to a near half open
position.
3. Turn the key switch to the “START” position. When
the engine starts, release the key. Check to be sure the
warning lights go out. If the engine fails to start after
cranking for approximately 10 seconds, refer to the
following COLD WEATHER STARTING
information.
4. Allow the engine to idle a few minutes before
advancing the throttle and/or engaging the PTO. In
cold weather, run the engine at half throttle for a few
minutes to allow engine oil and transmission oil to
warm-up.
Cold weather starting
If the engine fails to start using the preceding warm weather
starting procedure or when starting the engine in cold
weather;
1. Depress master brake pedal fully and move the PTO
and transmission selector levers to the off and neutral
positions.
2. Move the hand throttle forward to the full-open
position.
3. Turn the key switch to “HEAT” to preheat the
precombustion chamber and wait until the glow plug
indicator warning light on the instrument panel goes
out (approximately 5 seconds).
4. Turn the key switch to the “START” position. When
the engine starts, release the key. Check to be sure the
warning lights go out.
IMPORTANT: In cold weather below 23 degrees F (5
degrees C) start the engine after holding the key switch to the
“HEAT” position for approximately 10 seconds even if the
glow plug indicator warning light has gone out.
Starting the engine with jumper cables
WARNING: Start engine only from the operator’s
seat.
WARNING: If ice is present or the battery is
cracked, Do not attempt to jump start the vehicle.
If it is necessary to use jumper cables to start the engine,
follow the instructions below.
1. Bring helper vehicle with a battery of the same voltage
as disabled machine within easy cable reach.— The
