Routine Care F Cleaning the Keyboard Follow all safety precautions stated earlier before cleaning the keyboard. CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the keys. • Visible debris underneath or between the keys can be removed by vacuuming or shaking. • Canned, pressurized air can be used to clean debris from under the keys. Caution should be used as too much air pressure can dislodge lubricants applied under the wide keys. • If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool is available through many electronic supply outlets. CAUTION: Never remove a wide leveled key (like the space bar) from the keyboard. If these keys are improperly removed or installed, the keyboard might not function properly. • Cleaning under a key can be done with a swab moistened with isopropyl alcohol and squeezed out. Be careful not to wipe away lubricants necessary for proper key functions. Use tweezers to remove any fibers or dirt in confined areas. Allow the parts to air dry before reassembly.

•

Canned, pressurized air can be used to clean debris from under the keys. Caution should be used as

too much air pressure can dislodge lubricants applied under the wide keys.
