periodic cleaning
lenses and reflectors
Even a fine layer of dust can reduce the luminous output substantially. Regularly clean all lenses and the reflector using a
soft cotton cloth, dampened with a specialist lens cleaning solution.
fans and air passages
The fans and air passages must be cleaned approximately every 6 weeks; the period for this periodic cleaning will depend,
of course, upon the conditions in which the projector is operating. Suitable instruments for performing this type of mainte-
nance are a brush and a common vacuum cleaner or an air compressor.
periodic maintenance
lamp
The lamp should be replaced if there is any observable damage or deformation due to heat. This will avoid the danger of
the lamp exploding.
mechanicals
Periodically check all mechanical devices for wear and tear; gears, guides, belts, etc., replacing them if necessary.
Periodically check the lubrication of all components, particularly the parts subject to high temperatures. If necessary, lubri-
cate with suitable lubricant, available from your
coemar
distributor.
electrical components
Check all electrical components for correct earthing and proper attachment of all connectors, refastening if necessary.
fuse replacement
Locate the fuse, which protects the lamp and electronics, in the base of the
