Canon DS-8 - Manual (Page 55)

Cleaning the Aperture Section
The aperture section, the section where the fiim is held by the pres­
sure plate, should always be kept clean. It is best to clean this
section with a blower or a soft brush whenever new film is loaded.
Do not use anything hard, such as a metal brush.
The pressure plate can be removed by unscrewing its tightening
screw.
■ When loading film, check to see that the sprocket guide and pres­
sure plate tightening screws are not loose to secure the positive film
abvance.
Proper Care of the Camera
1 Do not put fingerprints or other stains on the lens. Wipe
‘ gently with silicon cloth when removing stains and use a blower
for removing dust.
2 When using the camera on a rainy day or at the beach, moisture
and salt air adhere to it, which can result in stains, rust, and
corrosion. Remove them with a soft dry cloth as soon as possible.
3 ln hot climates, do not leave the camera insideclosedautomobiles
duringthe daytime or in direct sunlight.
4 In extremely cold areas, expose the camera gradually to the
outer air to prevent the lens from clouding. Since the perform­
ance of the batteries drops at temperatures of 0°C (32°F), keep them
warm with your body temperature until just before use.
5 Before putting the camera into its case, be sure to turn the
master switch to "OFF".
6 When the camera is not to be used for a prolonged period of time,
remove the penlight batteries. Do not keep naphthalene or cam­
phor near the camera.
