Installation Procedure

1. Install quick coupler (7) in the reverse order of removal.

   1. Use washers (6) as required, to obtain a maximum gap of 1.0 ± 1.0 mm (0.04 ± 0.04 inch) at the inside of the lift arms. Use an equal amount of washers (6) on each side to center quick coupler (7) on the lift arms.

Disassembly Procedure

Show/hide table

Cylinders equipped with lock valves can remain pressurized for very long periods of time, even with the hoses removed. Failure to relieve pressure before removing a lock valve or disassembling a cylinder can result in personal injury or death. Ensure all pressure is relieved before removing a lock valve or disassembling a cylinder.
