Push down on the plunger  and hold it down.
Put a tool holder  into the arm. During correct operation, the slide  moves in.
Release the plunger .
Try to remove the tool holder . During correct operation, the slide does not move in and the tool holder locks in position.
Measure the space between the slide and the tool holder. Use a feeler gauge . The correct space is between 0.014 in (0.36 mm) and 0.020 in (0.51 mm). If the machine is a DM-1 or DT-1, the correct space is between 0.005 in (0.13 mm) and 0.015 in (0.38 mm).
Add or remove 0.01 in (0.25 mm) shim washers, part number 45-0075, until the space is correct.
Once the gap is set reassemble the slider assembly with the spring and washer installed. Apply a layer of Lithium Tacky Grease to the finger, spring and washer.
NOTE: Refer to Step 5 for an illustration of the shim washers and image of the slider assembly for reference.
