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:
• You are sitting on the seat.
• The parking brake is engaged.
• The power take off (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 from the
locked position with the parking brake engaged or if
you rise from the seat when the PTO is engaged.
Testing the Safety Interlock System
Service Interval: Before each use or daily
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 the parking brake and
move the PTO to on. Try starting the engine; the
engine should not crank.
2. Sitting on the seat, engage the parking brake and
move the PTO to off. Move either motion control
lever (out of neutral locked position). Try starting
the engine; the engine should not crank. Repeat for
other control lever.
3. Sitting on the seat, engage the parking brake,
move the PTO switch to off and move the motion
control levers to neutral lock position. 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.
