MAINTENANCE
Please remember to
never
leave the microscope with any of the objectives or eyepieces removed and always protect
the microscope with the dust cover when not in use.
5.1
CLEANING THE MICROSCOPE
Accumulated dirt on the metal surface should be cleaned with a damp cloth. More persistent dirt should be removed
using a mild soap solution. The outer surface of the optics should be inspected and cleaned periodically using an air
stream from an air bulb. If dirt remains on the optical surface use a soft cloth or cotton swab dampened with a lens
cleaning solution (available from any camera store). A small amount of absorbent cotton wound on the end of a
tapered stick makes for a useful tool for cleaning recessed optical surfaces. Avoid using an excessive amount of
solvents as this may cause problems with cemented optics or the flowing solvent may pick up grease from the
mounts making cleaning more difficult.
5.2
LAMP REPLACEMENT
The illuminator lamp is the only item on your BRISTOLINE microscope that requires periodic replacement. To
replace the bulb – UNPLUG the microscope. Carefully rest the microscope on its back. Unscrew the two
thumbscrews on the bottom plate of the microscope. After the lamp has cooled remove the old lamp from the
socket. Without directly touching the surface of the new bulb with your fingers carefully place it into the socket.
Reattach the bottom plate with the two thumbscrews. Never operate the microscope unless the bottom plate is
secured properly. Return the microscope to the upright position.
Replacement bulbs –
The 3088F microscope uses Catalog No. 3368, 5 watt fluorescent bulb. Replacement bulbs
and other parts and accessories are available from your authorized BRISTOLINE dealer.

SERVICE
BRISTOLINE microscopes are precision instruments that require periodic servicing to keep it performing properly
and to compensate for normal wear. A regular schedule of preventative maintenance by qualified personnel is
highly recommended. Your authorized BRISTOLINE distributor can arrange for this service. Should you
experience problems with the microscope proceed as follows:
1.
Contact the BRISTOLINE distributor from whom you purchased the microscope. Some problems can
be resolved easily over the telephone.
2.
If it is determined the microscope should be returned to your distributor or BRISTOLINE for warranty
repair pack the instrument in its original styrofoam shipping carton. If you no longer have this carton
pack the microscope in a crush resistant carton with a minimum of three inches of shock absorbing
material surrounding it to prevent in-transit damage. The microscope should be wrapped in a plastic
bag to prevent styrofoam dust from damaging the microscope.
3.
Enclose a detailed letter in the shipping carton describing the nature of the problem, your name,
address and telephone number should.
