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:
You are sitting on the seat
The parking brake is on "ENGAGED"
The power take off (PTO) is disengaged "OFF"
The motion control levers are in 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 "ENGAGED" or if you rise from the
seat when the PTO is "ON" 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. Sitting on the seat, "ENGAGE" parking brake and
move PTO "ON". Try starting the engine; the engine
should not crank.
2. Sitting on the seat, "ENGAGE" parking brake and
move PTO "OFF". Move either motion control lever
(forward or reverse). Try starting the engine; the
engine should not crank. Repeat with other motion
control lever.
3. Sitting on the seat, "ENGAGE" parking brake, move
PTO "OFF" and lock the motion control levers in
neutral. Now 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.
