residue on or around the following areas:
• Hydraulic power unit—reservoir, valves,
fittings
• Hydraulic cylinders
• Ground area under the machine

malfunction is essential for safe machine
operation. An unsafe working condition exists if the
auxiliary platform lowering function does not
operate in the event of a main power failure.
1 Raise the platform slightly.
2 Disconnect the power source from the machine.
