Safety Interlock System (Hydraloc™) WARNING could result.
NEVER attempt to bypass or defeat the safety interlock system. Serious personal injury or death
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: Once started, the auxiliary hydraulic circuit will stay 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 80.
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.
