When dis-assembling the microscope for storage, always put the covers into the eyepiece
tubes to prevent dust settling inside the microscope lenses.
The 100X oil immersion objective should be wiped off with a piece of lens paper
immediately after using. If necessary, use optical lens cleaner sparingly.
Bulb replacement
: (Unplug unit from power source)
Loosen the screw knob on the underside of microscope and open the panel to expose the
bulb. Use a small screwdriver to loosen the screws holding (the two screws closest to the
bulb) the prongs of the halogen bulb. Note that the prongs of the bulb are held in place by
small brass plates which shift slightly when the screws are loosened. Remove the old
bulb.
Important: Do not touch the new halogen bulb with bare hands.
Wear gloves or
hold the bulb using tissue or lens paper. Body oils may damage the halogen bulb. Insert
prongs of replacement bulb into
top
of socket (above the brass plate) and tighten screws
slightly. (The brass plates will move up to hold the prongs in place.) Close door and
hand tighten the thumbscrew knob.
Fuse replacement
: (Unplug unit from power source)
Open the fuse holder by unscrewing knob in the direction of the arrow. Remove the old
fuse and insert replacement fuse. Replace fuse holder and screw in place.
