Checking the Operation of the Interlock Switches
Electrical System: Electrical System Quick Checks
The interlock system is for the operator's protection; do not bypass
any of the interlock system components. Check the operation of the
interlock system daily to assure the system is operating correctly.
If an interlock system component is out of adjustment or defective,
replace it before operating the machine.
The purpose of the interlock system is to prevent the engine from starting if:
•
the parking brake is disengaged
•
the traction control levers are not in the N
•
the machine is equipped with an operator presence switch and the operator
is not on the operator platform
To test the interlock system:
1. Try to start the engine with the parking brake disengaged; the engine should
not start.
2. Try to start the engine with either traction control lever in the F
R
position; the engine should not start.
EVERSE
3. If the machine is equipped with an operator presence switch, try to start the
engine without standing on the operator platform; the engine should not start.
Adjust or repair any of the interlock system components as
necessary so all of the interlock system operations function correctly
before returning the machine to service.
