MAINTENANCE AND CHECKS
MAINTENANCE PROCEDURE
CLEANING REMOVABLE PARTS
Wipe the forehead rest, the chinrest and the patient grip (if a pair of patient grips is used) with
a cloth moistened with a tepid solution of neutral kitchen detergent.
CLEANING LENSES AND PRISMS
REMOVING STAINS
1 Prepare a solution of ethyl alcohol 20% and ether 80%.
2 Remove dust from the lens and prism surfaces with the attached cleaning brush, or a
blower.
3 Using clean gauze, lightly draw a spiral from the lens/prism centre outward.
4 If the stain remains, repeat this 2 to 3 times.
5 If stains are persistent, call your dealer or TOPCON (see the back cover).
CAUTION
Before carrying out daily maintenance, remove the power cable
(to avoid electric shocks) and wait until the body has cooled
down (to avoid burns).
CAUTION
To prevent burns, do not touch parts inside the lamp cover
house during operation and immediately after switching off the
power supply.
NOTICE
To prevent discoloration and deterioration in the chinrest,
forehead rest and other plastic parts, do not use volatile
solvents for cleaning, such as benzine, thinner, ether or
gasoline.
Wipe parts with a cloth moistened with a tepid solution of
neutral kitchen detergent.
NOTICE
To avoid damaging lens surfaces, do not use tweezers or
similar equipment to hold the gauze.
