Cleaning Fiber Optic Lens:
For good drill alignment function, keep the fiber
optic lens clean. Normal service period is about
every 14 days, depending on conditions, more
often may be necessary. To service, lightly dust
off lens with a soft bristled paint brush. Make
sure lens is not loose. To remove any oily film,
use a minimal amount of isopropyl alcohol on a
cotton swab and lightly clean lens.
