Mamiya 7 II - Manual (Page 44)

Common Sense Camera Care and Practice
The Mamiya 7II is a precision optical/mechanical
instrument, built for heavy professional use and a
long service life, if properly treated and
maintained. Please observe these basic caveats:
• Read instructions before using camera.
• Protect camera against shocks and falls. Use
neck strap supplied with it, whenever possible.
•
Check the battery frequently and always carry
spares. The sealed battery supplied with the
camera may have been subject to storage
conditions which have reduced its service life.
•
Be sure to wipe battery contacts before
installation and watch correct polarity.
•
Battery life differs, depending on frequency of
use, type, age, storage condition, ambient
temperature (use External Battery Case in very
cold weather), etc.
•
Always remove the battery (and film) when
camera is not used for a period of time.
•
Always keep covers on lenses and camera
body.
•
Do not store the camera at temperatures
exceeding 40°C (105°F) and -10°C (15°F).
Also avoid humid or sea air environment.
•
Prolonged disuse shortens camera life.
Periodically exercise the shutter (at different
speeds, lens diaphragms and focusing mounts.
•
Protect camera against rain and moisture.
•
Do not touch lens surfaces. Use blower or lens
tissue to remove dust particles.
Specific Suggestions:
• Operate the film advance lever with easy
strokes. If moved too rapidly it may affect
spacing.
• Hold lens focusing mounts on bottom in order
not to block range finder window.
• Always test your equipment before going on
important assignments.
The Importance of Proper Maintenance
Your camera has mechanisms like film
transport, shutter and diaphragm blades,
rangefinder couplings, etc. They are controlled
by gears, levers, springs, and so on. All require
special lubrication from time to time. Ambient
conditions can also affect these mechanisms,
as well as the electronic components and the
optical glass of your lenses. We therefore
suggest that you have your camera and lenses
checked, and if necessary serviced,
periodically.
