3. OPERATION 3.11 LOWERING LIFT ARMS (ENGINE OFF) In the event that you should have an electrical failure which renders your skid steer inoperable with the lift arms up, the following procedures would apply. To avoid personal injury: Do not leave lift arms up unless the lift arm supports are engaged. WARNING 1. Lift Arm Height Is Sufficient To Engage Lift Arm Support Pins Engage lift arm support pins. (Fig. 3.10A) Raise seat bar and cycle all controls to ensure they are locked. Exit loader and open rear door. Locate the control valve on the RH side of the machine. Unplug the electrical wire and remove the knurled nut holding the solenoid on the spool lock.
Remove the solenoid, then remove the lock pin and spring assembly (Fig. 3.10C). Once the lock pin and spring are removed, the lift arm spool is free to travel. Enter the machine, being careful not to cycle the foot pedals or the control levers as the locking system has been disabled. Once in the operator seat, dis-engage lift arm support pins. Move the lift arm pedal or control lever to lower the lift arms to the ground. C694 Fig. 3.10A Lift Arm Lock Solenoid 2. Lift Arm Height Is Not Sufficient To Engage Lift Arm Support Pins DO NOT EXIT FROM FRONT OF LOADER WITHOUT LIFT-ARMS ON GROUND OR SUPPORTED BY ACCEPTABLE MEANS! Raise seat bar and cycle all controls to ensure they are locked.
If help is readily available, have someone place a suitable support under the lift arms (e.g. 4” x 4” Lumber) or a piece of angle iron between lift cylinder end cap and lift cylinder rod mount. Then exit loader using extreme caution. If help is not available, the operator must exit the loader from the rear window and perform the proper lift arm supporting (as described previously). Once this is completed, open rear door. Locate the control valve on the RH side of the machine (Fig. 3.10B). Unplug the electrical wire and remove the knurled nut holding the solenoid on the spool lock. Remove the solenoid, then remove the lock pin and spring assembly (Fig. 3.10C).
Once the lock pin and spring are removed, the lift arm spool is free to travel.

Once in the operator seat, have the assistant remove the lift arm support devices. The operator can then move the lift arm pedal or control lever to lower the lift arms to the ground.
