Mounting the attachment on optical sight
• Select the adapter (Available separately) with the required diameter of insert
depending on the outer diameter of the lens of your optical sight (see the
Table).
• The designation 42mm / 50mm / 56mm in the title of the adapter refers to
the optical diameter of the lens in the optical sight.
• Remove the cap (16) from the 42mm adapter (19) (#79171) by turning it
clockwise. To remove the cap from the 50mm (#79172) or 56mm (#79173)
adapters, turn it anticlockwise.
• Degreasing of the body of the sight before mounting is recommended.
• Mount the insert (18) onto the adapter (19) as far as it will go.
• Mount the adapter with the insert into the lens of the day sight (17).
• Move the lever (22) from its initial OPEN position to the CLOSE position.
• Ensure that the adapter fits snugly against the lens.
• If there is any gap, do the following:
– Loosen the locking screw (20) with an Allen key (S=2mm).
– Tighten the screw (21) with an Allen key (S=4mm) with the force necessary
to ensure that the adapter fits tightly against the lens. The clamping forces
should be 1 Nm.
– Tighten the locking screw (20).
• The effort can be tested with a torque screwdriver.
• Insert the attachment firmly into the adapter so that the pins located in the
adapter case fit into the grooves (23) of the attachment. Turn the attachment
clockwise as far as it will go. The triangular mark on the attachment and the
square on the adapter body must be aligned.
• To align the attachment, turn the handle (22) to the OPEN position and align
the attachment with the horizon.
