Engine starting

The TrimStar Hydro 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. Cruise control is in the neutral (down) position.
Fig. 3-5
B. Deck clutch switch is in the disengaged (down)
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
cruise control is not in neutral (up) or the deck clutch switch
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 cruise control's
neutral switch and the deck clutch interlock
system. Severe personal injury could result
when starting the unit if the operator presence
switches are engaged.
The following steps are the correct procedures for
starting the engine. If difficulty is encountered, contact the
Authorized Hustler Dealer in your area.
