●Notes for tightening screws
The types of screws used
for the supplement are
those that carve grooves
into the plastic as they are
inserted (self-threading).
When tightening screws,
firmly press the provided
screwdriver straight against
the screws and turn. It is
said that 70 percent of the
force applied is used for
pushing against the screw
and 30 percent for turning it.
If any screws are loose, gaps
may remain or the projector
may operate poorly.
●How to insert the batteries
Insert three AA alkaline
batteries into the battery
box, turn the switch ON,
and confirm that the
light source lights up.
Make sure that the positive and negative
terminals of the batteries are aligned correctly.

●Difference between Single/Super 8,
and Double 8 lms
Single/Super 8
Double 8
There are two types of
8mm films: Single 8 or
Super 8 (1965-1974) and
Double 8 (1955-1964).
The positions of the holes
that are used to advance
the film differ depending on the type of film. For
Double 8 films, the frame border, etc. must be
changed (refer to the back of this sheet for details).
＊For how to set Double 8 lm, refer to the back of this
sheet.
Mount the shot and developed 8mm lm
to the lm advance reel axis.
Attach the axle adapter to the lm advance reel axis.
Then, mount the film. At the same time, mount the
rewind reel to the rewind reel axis.

●Pay attention to the
position of the holes
on the film (left side
when viewed from the
projection lens side)
when mounting the lm.

●It is difficult to
feed lm that is bent
at the tip. In such a
case, cut it straight
using scissors.
Check the arrows engraved on the
main unit of the film projector and
thread the lm in order.
Leave the top section of
film a little loose when
setting the lm in place.

●How to thread the film
through the lens portion
Unlock the film holder and
thread the film straight
through the opening.
If the film is curled, try to
straighten it when inserting
the lm.
Unlock the lm holder.
Wind the tip of the film to the rewind
reel.
Wind the lm about
3 revolutions.
Projecting Images on
a Screen
Prepare a dark room.
The darker the room is, the better. A commercially-
available screen or white wall can be used for projecting
the images. (Images cannot be projected on a colored
wall.)
First, turn on the switch.
Turn on the switch.
Project the image from the lm onto the
screen, and bring the image into focus.
Move the projection lens in and out.
Rotate the projection lens to
move the lens in and out.
Projection lens
Set the projection size.
Adjust the distance and height of the lm projector
and screen according to the size and height of the
image being projected.
Bring the image into focus once the position has
been set.
Adjust the frame feed and project
the image.
If the frame shown in the
right figure can be seen,
advance the lm for a few
frames, turn the framing
knob, and adjust the
position of the frame. After
the position is adjusted,
turn the handle to project
the images. (Turn the
handle slowly at rst.)
Framing knob
Turn the handle
clockwise while
rmly holding down
the lm projector.
After projecting the film, rewind
the lm.
Mount the wound lm reel to the lm advance
reel axis making sure that the direction is as
shown in the
gure. Rewind
the film by
turning the
handle (be
sure to turn
the handle
clockwise).
Hold down the film
projector when turning
the handle.

Replacing a Broken Belt
If the film advance belt is broken or becomes loose and
does not properly rotate the reel, a rubber band can be
used as a replacement. In such a case, replace the belt as
shown in the gure below.
Remove the sprocket and handle.
Remove the back cover and the gear cover
inside.
Replace the belt.
As shown in the gure, hook the new belt (rubber band) to the spool of
the gear cover and the spool for the rewind reel.
Reattach the parts with the screws.
Set the gear cover and sprocket in place and rst secure the sprocket
side with a screw. Then secure the gear cover side with a screw and
nally attach the back cover.

Q: The lm does not go through the frame border.
A: It is difcult to feed lm that is bent at the tip or bends toward the light source in.
If the lm is curled, try curling the tip slightly toward the front (toward the lens).
Q: Film feed is irregular.
A: Make sure there is enough play in the lm between the sprockets and the lens. If
the lm is too tight, the frame will be unstable, creating blur.
A: Frames can also skip on lm that has hardened after long years in storage.
A: The projector is shipped set up for Single 8 or Super 8. If you have Double 8 lm,
change out the necessary parts.
Q: Film feed is irregular at the edited part.
A: If cellophane tape is used, frames skip in an edited section. Use special splicing
tape to make sure frames feed properly.
Q: Film jams at the edited part.
A: There may be wrinkles in the tape you used or bits sticking out from the sides of
the lm that are catching. If something like this is happening, remove the tape and
redo the edits.
Q: Film does not rewind.
A: The rewind reel axis can be put at different angles depending on the reel size. Belt
tension is lower at the bottom position, so put the axle at the upper position if you
are using the provided rewind reel. If you are regularly using the reel at the bottom
position, replace the belt with a smaller rubber band to keep it steady.
Q: I want to replace the lm partway through.
A: You cannot change the lm while the projector is running. Run the lm to the end,
then rewind it onto the rewind reel.
A: If you need to remove the lm partway through due to lm problems, remove the
four front screws holding the frame border in place and remove the lm.
Q: The light source is dim.
A: Check the orientation and type of the batteries. The LED may also stop emitting
light if the voltage from rechargeable batteries, such as NiCd batteries, is too low.
Q: The lm broke while projecting.
A: The adhesive on edited areas of old lms can weaken and break. Align the broken
ends of the lm with the lm editing tool and redo the splices with splicing tape.
Q: The projector is damaging the lm.
A: If something is stuck somewhere on the lm travel path, it can scratch the lm.
Remove dirt and dust before projecting lms.
Q: The image is upside down.
A: The lm is traveling the wrong path. Rewind it on a different reel and then project
it.
Q: I want to stop the lm to project a single frame.
A: The projector uses an ultra-bright white LED as its light source. Since it is not as
hot as a light bulb, the lm will not be damaged by the heat if you stop the lm while
projecting.
