The IDEAL 11-11X is an electric marker designed to scribe marks into various materials that cannot be wiped away. It is intended for marking sizes, names, numbers, and other important information on surfaces.
To operate the unit, hold it like a pencil in a normal writing attitude. The device comes pre-adjusted from the factory, but if adjustment is needed, turn the wheel to decrease until stopped, then increase approximately 16 notches for general use. For finer adjustments, turn one notch at a time.
The marker scribes into surfaces to leave marks that cannot be wiped away or worn off with ordinary use.
The text specifies Rockwell hardness scale C when discussing hard surfaces like dies and drills.
Turn the adjusting wheel to the left approximately 16 notches from the stop position.
