7. ROUTINE MAINTENANCE
The maintenance outlined below should only be carried out once the
main power cable has been disconnected. If you have any problems that
are not covered by the procedures described below, contact Keeler Ltd or
your local supplier.
7.1 LED SYSTEMS
LED’s typically have a life exceeding 10,000 hours of continuous use and therefore can be
considered as a non-consumable item that will not require changing by a user.
Whilst this is a significant life expectancy, we suggest that the Slit Lamp is always switched off
between examinations to conserve energy and LED life.

In the unlikely event of an LED failure please contact Keeler or your local
distributor for guidance on the replacement procedure.
7.2 REGULARLY INSPECT THE DEVICE FOR DAMAGE OR DIRT
Routinely clean as per section 3 on page 5 cleaning instructions.
7.3 CLEANING AND CHANGING THE MIRROR
The mirror is front surfaced to avoid ghosting of the projected light and therefore
is very delicate and will need to be replaced when the surface deteriorates.
The mirror should be cleaned only with a soft clean lens cloth.
The mirror is an interference fit in its holder and can be removed by grasping it
firmly and pulling it out of its holder. Slide in the replacement mirror taking care
to avoid touching the reflective surface.
Care must be taken to keep the objective and the eyepiece lenses clean – use
only soft clean lens cloths to clean optical surfaces.
7.4 ELECTRICAL CONNECTIONS
Routinely check all electrical connections, cables and connectors. To access the bulb
connections see earlier in this section for guidance.
7.5 OPTICS
The optics should be wiped clean of any loose dirt or debris with a suitable dust brush then
cleaned with a soft dry lens cloth, washed linen or other non abrasive lens cleaning material.
The condenser lens beneath the illumination lamp will require cleaning; to access this, remove
the lamp as detailed earlier, clean the condenser lens and then replace the lamp.
7.6 AXLE AND MECHANICAL PARTS
If the Slit Lamp becomes hard to move on the glide plate, the plate should be cleaned with a
lightly oiled cloth or silicon polish. The axle should be cleaned only with dry lint free cloths.
8. WARRANTY
The Keeler H-Series Slit Lamps are guaranteed for three years against faulty workmanship
materials or factory assembly. Warranty is on a Return To Base (RTB) basis at the cost of the
customer and may be void if the Slit Lamp has not been regularly serviced.
The manufacturer’s warranty and terms and conditions are detailed on the Keeler UK website.
The mirror, main illumination lamp and general ‘wear and tear’ are excluded from our standard
warranty.
