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
engine from starting unless:
The parking brake is engaged.
The PTO is disengaged.
The motion control levers are in the neutral locked
position.
The safety interlock system also is designed to stop the
engine when the traction controls are moved with the
parking brake on or if you rise from the seat when the PTO
is engaged.
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 below, have an Authorized Service Dealer repair
the safety system immediately.
1. While sitting on the seat, engage the parking brake and
move the PTO to On. Try starting the engine; the engine
should not crank.
2. While sitting on the seat, engage the parking brake and
move the PTO to Off. Move either motion control lever
(forward or reverse). Try starting the engine; the engine
should not crank. Repeat with the other motion control
lever.
3. While sitting on the seat, engage the parking brake,
move the PTO to Off, and lock the motion control
levers in neutral. Start the engine. While the engine is
running, release the parking brake, engage the PTO, and
rise slightly from the seat; the engine should stop.
4. While sitting on the seat, engage the parking brake,
move the PTO to Off, and lock the motion control
levers in neutral. Start the engine. While the engine is
running, center the motion controls and move (forward
or reverse); the engine should stop.
