The Safety Interlock System

If safety interlock switches are disconnected
or damaged the machine could operate
unexpectedly causing personal injury.
• Do not tamper with the interlock
switches.
• Check the operation of the interlock
switches daily and replace any damaged
switches before operating the machine.
Understanding the Safety Interlock
System
The safety interlock system is designed to prevent
the engine from starting unless:
• The blades are disengaged.
• The motion control levers are in the park
position.
The safety interlock system also is designed to stop
the engine when the control levers are out of the
park position and you rise from the seat when the
blades are engaged.

the machine each time. If the safety system

The throttle control regulates the engine speed as
measured in rpm (revolutions per minute). Place
the throttle control in the Fast position for best
performance. Always operate in the full throttle
position.
The machine can spin very rapidly. The
operator may lose control of the machine
and cause personal injury or damage to the
machine.

• Slow the machine down before making
sharp turns.
