See 3M ASD Accessory catalog 61-5002-8098-9 and 61-5002-8097-1 for additional Accessories.

Removing and remounting shanks and shaft mounted abrasive products into collet chuck

1.Disconnect air line from tool.

2.Remove currently mounted shaft accessory, shank or abrasive product from collet chuck* by using the two wrenches supplied with the tool. Use the wrench to secure the collet body while turning the collet nut counter clockwise.

3.After the existing product has been removed from the collet, inspect the collet insert to ensure that is free of debris and undamaged.

4.Fully insert the new shaft mounted accessory, shank or abrasive product into the collet.

5.Secure the collet body with the wrench and tighten the collet nut securely. Always use the correct sized collet with the matching shank (use 1/4 in collet insert with 1/4 in shafts or 6 mm collet insert with 6 mm shafts). An inadequately inserted shank could bend or break causing damage to the tool and work piece and possible injury to the operator or bystanders.

Note: During the above steps, ensure that all hardware and abrasive products are mounted concentrically on the supporting accessory.

*In the drawings on the Parts Pages, Figures 1, 2 and 3 comprise the Collet Chuck.
