I just bought a nice pair of Optolyth Touring 8x32 (brand new) but the focus wheel turned out to be stiff.. Is there any way to solve the problem without completely disassembling the binocular or adding repair marks on it?
Stiff wheel? 1) put a thin oil 2) use a dryer to disolve the old hard grease 3) try to move with hot temperature. 4) repeat operaltion. OBS: CERTIFY THAT NO CONTAINS PLASTIC PIECES. DRYER CAN MELT IT
I tried to do that. At first it moved with difficulty, so I thought that the dryer might make it move more smoothly, but after it cooled, it became very solid. I tried putting some light grease on it, but nothing happened. Is there a specific place you recommend applying grease to?
