CARE TIPS
If your Leica will not be used for a long period, ensure that it is
stored in a dry, well ventilated location.
Photo cases that became wet during use should be emptied to
prevent damage to your equipment caused by moisture and any
leather-tanning residue released. To prevent fungal growth during
use in hot, humid tropical climates, the camera equipment should
be exposed to the sun and air as much as possible. Storage in
airtight containers or cases is only recommended if a desiccant,
such as silica gel, is also used.
As any dirt may also be a breeding ground for micro-organisms, the
equipment should be carefully kept clean.
All mechanically operated bearings and sliding surfaces on your
Leica are lubricated. Please remember this if you will not be using
the camera for a long period of time. To prevent the lubrication
points from becoming gummy, the camera should be wound on
several times and released with every shutter speed with no film
loaded every three months. It is also recommended that you
repeatedly move and use all other controls, such as the image field
selector.
A lens works like a magnifying glass if bright sunlight shines on the
front of the camera. The camera should therefore never be set
aside without protection against strong sunlight. Fitting the lens
cover and keeping the camera in the shade (or directly in the case)
help to prevent damage to the interior of the camera. To remove
stains and fingerprints, the camera should be wiped with a clean
lint-free cloth. Tougher dirt in hard to reach corners of the camera
body can be removed with a small brush.
Do not use liquid cleaning agents to clean the housing. Dust and
lint inside the camera (e.g. on the film guides) are best removed
carefully with a soft hair brush that has been repeatedly degreased
in alcohol and then dried. Be careful not to damage the shutter
curtain with the shaft of the brush.
Note the serial number of your Leica M-A (engraved on the
accessory shoe), as it is extremely important in case of loss.
