• Hold the lower sprocket with your right thumb and rotate the ta-
ke-up core counter-clockwise to remove any slack.
• Thread the film around the upper sprocket and adjust the loop
until its taut length is 14 to 15 frames long outside of the nose.
When the proper length is achieved, close the upper pinch roller un-
til it locks firmly in position.
• Remove any slack, then close and lock the take-up door.

THE MAGAZINE
The Two-Finger Rule
When loading the take-up side
of the magazine, the loop size
can quickly be measured by in-
serting two fingers within the
loop perpendicular to the
mag's pressure plates.
At first, determine proper loop
size by pulling the looped film
away from the mag, counting
and adjusting for 15 to 16 vi-
sible perforations for a length
14 to 15 frames long. Then,
insert two fingers and check
how the spacing relates to the
proper loop length. Of course,
each person's finger-measured
equivalent will be slightly dif-
ferent, but for most people, a
tight two-finger length is ap-
proximately a 14 frame loop, a
loose two fingers is about 15
frames. After you become fa-
miliar loading the mag, you
should be able to use the two-
finger method to save time set-
ting your loop.
