Replacement of Affected Unit: Refer to SEBU7629, "Quick Coupler Installation and Removal".

1. Remove the affected Manual Pin Grabber Quick Coupler.

2. Install the new Manual Pin Grabber Quick Coupler.

Disposal of Affected Unit:

The affected coupler that was removed should be rendered permanently unusable before disposal. The following steps are guidelines for rendering the coupler permanently unusable.

1. Destroy the affected coupler?s serial number tag by cutting through the serial number.

2. On the affected coupler, Flame cut the fixed hook and lifting eye off of the coupler frame and notch out the pin bores in the regions depicted by the dashed lines in Image 1.1.1 to render it unusable. As a result, the coupler should not be capable of holding an attachment, be used as a lifting device, or be able to be pinned onto a machine.

3. On the affected coupler, flame cut the hex screw adjuster (item 1 in Image 1.1.2) off of the mechanical cylinder as close to the cylinder body as possible (refer to the dashed line in Image 1.1.2) to render it unusable. As a result, the mechanical cylinder should not be able to be operated or used as a replacement part on any other coupler.
