The Safety Interlock System

CAUTION
If the 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 or the parking brake
is engaged.
•
The power take-off (PTO) is disengaged.
•
The motion-control levers are in the neutral locked
position
•
The engine temperature is below the maximum
operating temperature.
The safety interlock system also is designed to stop
the engine when the traction controls are moved from
the neutral locked position with the parking brake
engaged. If you rise from the seat when the PTO
is engaged there is a 1-second delay and then the
engine stops.
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 the neutral locked 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 within 2 seconds.
4. Without an operator on the seat, engage the
parking brake, move the PTO switch to off and
move the motion control levers to the neutral
locked position. Now start the engine. While the
engine is running, center either motion control;
the engine should stop within 2 seconds. Repeat
for the other motion control.
5. Without an operator on the seat, disengage the
parking brake, move the PTO switch to off, and
move the motion control levers to the neutral
locked position. Try starting the engine; the
engine should not crank.
Using the SCM to Diagnose
System Problems
The machine is equipped with a standard control
module (SCM) monitoring system that tracks the
function of various key systems. The SCM is located
under the right control panel. Access it through the
side panel cover (Figure
