Pentax makes a series of binoculars. These optics are made for field use and have a variety of magnifications and casings. All Pentax binoculars have ground glass lenses and focus adjustment dials. If you have a pair of Pentax binoculars in need of adjustment or repair, work on everything except the lenses on your own. Pentax strongly recommends you do not attempt to reset lenses that have fallen out or have become dislodged in the optic chambers, as this may lead to eye damage due to uncalibrated optics.

Instructions

  1. 1

    Pop the dial adjustment cap off the centre focus adjuster on the Pentax binoculars. Locate this cap on the centre dial. If necessary, pry it out gently with the flat end of a flathead screwdriver. Unscrew the centre lock screw on the dial once the cap is off. Use the small optic-sized Phillips screwdriver to remove the screw.

  2. 2

    Blow some compressed air onto the screw, and bolt. Clean out the dial screw hole and add one drop of dry lubricant to the bolt. Screw the dial back onto the bolt and push the dial adjustment cap back onto the dial.

  3. 3

    Twist the end of the optic barrels to test the lenses covers. If the seams on the lens covers are loose, add a drop of clear liquid adhesive to a small hobby paintbrush and push the adhesive into the seam. Hold the seam down to the barrel for five minutes to set the adhesive.

  4. 4

    Blow the lenses off with the compressed air and wipe them off with the dust-free chamois cloth.
