- 1). Gently turn the external guard ring (the outermost ring on the forward-facing part of the binoculars) in a counterclockwise motion and remove it (all rings will come free in a counterclockwise motion). If the ring does not turn by hand, use a strap wrench (as you would to remove an oil filter from a car).
- 2). Unscrew the retaining ring from the front of the objective housing (the second ring behind the guard ring) using a spanner wrench.
- 3). Remove the objective ring (the notched ring located behind the retaining ring within the objective cell; this manages the motion of the forward lens) with a jeweler's straight slot screwdriver; this should free the objective cell (which is 1 1/2 to 2 inches long, depending on the power of the binoculars) so you can remove it as well.
- 4). Hold the objective cell in one hand and unscrew the objective bell housing from the front of the unit (this may also require the use of a strap wrench).
- 5). Repeat this process for the other scope.
