cleAning The eyepiece

you may need to clean the eyepiece of the riflescope from time to time in order to guarantee 

top performance. When you receive your riflescope you should check for dust on the eye-

piece of the unit.
First you will need to remove the eyepiece. to do that you will need to 

initially loosen the fixing screw that can be found on the base. then 

unscrew the eyepiece counter-clockwise to remove it.

NOTE:

 

You do not have to remove the set screws completely, they are 

very small and easy to misplace.

CAUTION:

 Use only Photographic lens cleaning tissue on these sur-

faces. Be careful not to scratch or smudge any of these surfaces. When 

using compressed air to blow dust away, make sure to avoid invert-

ing the can while spraying. This can cause frozen propellant to exit the 

can, which can cause serious problems with the glass and phosphor 

screen.
