Safety Interlock System (Hydraloc™)
NEVER attempt to bypass or defeat the safety
interlock system. Serious personal injury or death
could result.
The Hydraloc™ safety interlock system provides for operator safety. The interlock
system:
•
Prevents the engine from starting unless the operator is sitting in the operator’s seat
with the restraint bar lowered.
•
Disables the lift arm, auxiliary hydraulics, attachment tilt and wheel drive hydraulics if
the restraint bar is raised, the ignition keyswitch is turned off or the operator’s seat is
not occupied.
Note:
The auxiliary hydraulic circuit can be detented in the “on” position for continuous
operation with the restraint bar raised and operator out of the seat. See“Auxiliary
Hydraulic System” on page 79.
Safety Interlock System Test
Each time before using the machine, check the safety interlock system daily for proper
operation:
Seat Switch Test
With the engine off and the restraint bar lowered, unfasten the seat belt, and lift your
weight off the seat. Try to start the engine. If the engine starts, turn off the engine,
troubleshoot and correct the problem. Contact your dealer if necessary.
Restraint Bar Test
With the engine running, raise the restraint bar. Test each of the controls. The lift arm,
hitch and drive should move only slightly. If there is any significant movement,
troubleshoot and correct the problem immediately. Contact your dealer if necessary.
