Safety Interlock system for more information.
7. Transmission shift lever (Fig. 3-5) — this lever shifts
the transmission into different gears.
NOTE:
The
operator must disengage clutch before shifting gears.
Engine starting
The TrimStar safety interlock system is also designed to
protect the operator and others from accidental injury due to
unintentional engine starting. The engine will not start until:
A. Blade engagement lever is in the disengaged
(down) position.
B. Transmission shift lever is in the neutral position.
WARNING:
The safety interlock system must
not be disconnected or bypassed.
NOTE:
The machine is equipped with operator presence
control switches. If for any reason the operator should
release both of the operator presence control levers when the
transmission shift lever is in the drive position or the blade
engagement lever is engaged (up position), the engine will
stop.
DANGER:
The operator presence switches
should never be engaged when starting the unit.
When the operator presence switches are
engaged, they override the neutral switch and the
deck drive interlock system.
Severe personal
injury could result when starting the unit if the
operator presence switch is engaged
. The following steps are the correct procedures for starting
the engine. If difficulty is encountered, contact the
Authorized Hustler Dealer in your area.
1. Before starting tractor each day, perform daily pre-
operation checking.
2. Shift the transmission to neutral.
3. Blades engagement lever must be in the “Off” position
or back.
4. Thumb latches need to be in the “Neutral Lock”
position.
5. When the engine is cold set throttle/choke lever to the
choke position. Avoid flooding and operate engine
without choking as soon as possible.
When the engine is already warmed up set throttle to
approximately 1/2 throttle position.
6. Insert key in ignition switch and rotate full clockwise
and pull engine recoil start rope.
7. Perform test to make sure safety interlock system is
operating properly. Refer to Safety interlock system
section.
8. Allow the engine to idle a few minutes before
advancing the throttle and engaging the blades.
Push
blade engagement lever forward to engage blades.
9. Before stopping the engine, place the transmission
lever in the neutral position, set thumb latches in the
neutral locked position, disengage the blade
engagement lever, and throttle back to 1/2 throttle for a
couple of minutes; then rotate ignition key counter-
clockwise to the OFF position. Remove the key from
switch before leaving the tractor.
WARNING: Never leave the machine
unattended with key in ignition switch.
Safety interlock system
The unit is equipped with a safety interlock system
consisting of the neutral switch (Fig. 3-1), operator presence
control levers (Fig. 3-3), and deck switch (Fig. 3-1).
Check the safety interlock system daily, prior to
operation. This system is an important safety feature. It
should be repaired immediately if it malfunctions. The
machine incorporates two operator presence control
switches which will stop the tractor engine when the
operator releases both of the operator presence control levers
for any reason while the tractor is operating. However, if
only one operator presence control lever is released, the unit
will continue to operate. This is a safety feature designed to
prevent runaway or accidental entanglement. To inspect the
system:
1. Place the transmission lever in the neutral position,
move thumb latches to the neutral lock position, and
move blade engagement lever to the “OFF” (back)
position.
2. Start the engine and allow it to warm up to operating
temperature.
3. With the transmission shift lever in the forward or
reverse position and/or the blade engagement lever in
the engaged (forward) position, slowly release both
operator presence control levers.
