10.0 Maintenance
The Mamiya 645DF+ generally needs very little maintenance. But this is
a professional tool and should be treated with care and caution. Always
do test shots before a photographic session if the camera has not been
used for a long period of time.
A frequently used product should be inspected periodically at the nearest
official Mamiya Leaf repair center. Do NOT try to repair any camera, lens
or back errors or malfunctions – consult your local dealer.
10.1 Changing the Focusing Screen
1. Remove the lens.
2. Pull the Focusing Screen Release lever
A forward, as illustrated, with
tweezers to ease the focusing screen down.
3. Remove the focusing screen from the focusing screen frame
by grasping the tab on the edge of the screen with tweezers as
illustrated.
4. When installing the screen, pinch the tab of the screen with tweezers,
and place the screen on the screen frame.
5. Push the screen frame up using the tweezers until hearing a clicking
sound. The screen is now properly installed. Never press down on
other parts as this affects the focus function.
Notice:
Since the focusing screen’s surfaces are
soft and easily damaged, handle them
carefully.
Never touch the surface with bare
fingers. Should dust settle on it, merely
blow away by using a blower.
If the focusing screen needs cleaning,
send it to the nearest authorized Phase
One service center.
Do not attempt to clean the surface
of the focusing screen, as it is very
delicate.
Do not touch and damage the mirror in
any way.
