3. Eyepiece is dirty. See “Care and Cleaning” Section.
D. PROBLEM – Dust or hairs seem to be moving in the image.
CORRECTION – The iris diaphragm is not open wide enough. Slowly
open the diaphragm to increase the size of the opening allowing
for additional illumination.
E. PROBLEM - Once the specimen is in focus, it moves out of focus.
CORRECTION – Gravity is causing the stage to drift downward,
causing loss of focus. The focusing tension should be increased to
act as a brake to prevent this downward drift. The M3600 Series is
outfitted with a tension collar on the course focusing shaft to allow
tension on the slip-clutch system to be increased or decreased. See
page 11. The M3700 uses a more complicated coaxial focusing
system. Please call the Swift repair department for more
information at (877) 967-9468.
F. PROBLEM – Focusing knobs turn with difficulty.
CORRECTION –
1. Loosen the tension collar adjustment. See page 10.
2. The microscope should be disassembled, cleaned and
re-lubricated by a qualified, authorized technician.
