The Safety Interlock System
Caution
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
mower from starting unless:
The blade control switch (PTO) is pushed off.
The speed control lever is in neutral.
The safety interlock system is designed to kill the engine
when:
The Operator Presence Control (OPC) levers are
released.
The speed control lever is shifted out of neutral
without holding OPC levers.
The blade control switch (PTO) is pulled on without
holding the OPC levers.
Testing the Safety Interlock System
Test the safety interlock system before you use the
machine each time. If the safety system does not operate
as described, have an Authorized Service Dealer repair the
safety system immediately.
1. Set the neutral locks and place speed control lever in
neutral. Start the engine; refer to Starting and Stopping
the Engine, page 19.
2. Without holding the Operator Presence Control (OPC)
levers, pull the blade control switch (PTO) up. The
engine should kill.
