# Stepped Block Accessory Installation and Operation

The Atlas Copco Stepped Block enables the ACMS08T and the ACHS14T to be used in a joint with a larger gap, and to be used to open a joint further with less penetration (allowing, for example, spectacle blinds to be changed with ease).

The stepped blocks can be used individually or as a pair.

1. Attach the stepped block to the tool using the M6 countersunk screw.

2. Insert the tool into the joint.

   Make sure that there is a minimum hold of 15 mm (0.59") and that the full width of the block is used.
