To remove the handle cap, push the cap all the way to the left side of the imprinter as shown. Apply pressure to the top of the cap, in the same direction. You will need a small Phillips head screwdriver and a .050 hex key wrench to adjust this imprinter. Adjust screws in 1/8 turn increments or less and run a sample print. See the diagram below for more instructions. When adjustment is complete, replace handle cap. Note: Adjusting imprint too dark, can cause the print head to lock or be hard to move. If this occurs, adjust screws back (counter-clockwise) until print head moves freely.
