The Safety Interlock System
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
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 30). To open
