Safety Interlock System
NEVER defeat the safety interlock system by
mechanically or electrically bypassing any switches, relays or solenoid
valves.
An interlock system is used on the loader for operator safety. Together with
solenoid valves, switches and relays, the interlock system:
» Prevents the engine from starting unless the operator is sitting on the seat
and the operator restraint bar is down.
» Disables the lift arm, attachment tilt and wheel drives anytime the operator
leaves the seat, turns the keyswitch to
OFF
or raises the restraint bar.
» Disables the engagement of the auxiliary hydraulics anytime the restraint
bar is raised or the keyswitch is
OFF
.
Testing the Safety Interlock System
Before leaving a parked machine, check the safety interlock system for
proper operation:
Restraint Bar
With the engine running, raise the restraint bar. Test each of the controls.
There should be not more than a slight movement of the lift arm, hitch and
machine. If there is any significant movement, troubleshoot and correct
the problem immediately. Contact your dealer if necessary.
Seat Switch
With the engine off and the restraint bar lowered, unfasten your seatbelt.
Lift your weight up off the seat. Try to start the engine. If the engine starts,
turn off the engine, and troubleshoot and correct the problem. Contact
your dealer if necessary.
