GLUE ADJUSTMENT
The glue level may require adjustment
when the thickness of the book or pad
varies. Use the following book spine
illustrations for guidelines.
• Increasing the holt-melt glue when
Hollow OR Round
• Decreasing hot-melt glue when
Too much OR Nail head
glue on
both sides
• Adjusting the glue level:
1. Turn the glue adjustment lock knob
counter clockwise to loosen.
2. Increase the amount of glue by sliding

GLUE ADJUSTMENT
Note that the thickness of the cover
sheet is an important factor for you to
make a good spine. Use only the
suitable thickness of the cover sheet
associated with the appropriate glue-
meter position to make a good book.
NIPPING PRESSURE CONTROL
The nipping pressure control knob is
located on the left-side of the machine
(next to the power switch). It allows you to
adjust the nipping pressure based on the
thickness of the books and the quality of
the book spine. Normally the thinner the
books, the more the nipping pressure.
The factory setting is set to the mark
on the scale.
• Turn the knob clockwise to increase the
nipping pressure when round spine
occurs or making thinner books.

REPLENISHING THE GLUE TANK
CAUTION: GREAT CARE MUST
BE TAKEN WHEN HANDLING
HOT MOLTEN GLUE. BE SURE
NOT TO PLACE AN EXCESSIVE
AMOUNT OF GLUE IN THE TANK AT
ONE TIME. KEEP IT AT SUCH A LEVEL
THAT THE GLUE WILL NOT GO OVER
THE MAX. LINE IN THE TANK WHILE
THE APPLICATION DRUM IS
ROTATING. THIS WILL PREVENT GLUE
FROM SPILLING OUT OF THE TANK.
Glue Replacement:
WARNING: DO NOT ATTEMPT TO
REMOVE THE DRAINING TRAY
UNTIL THE GLUE COOLS DOWN.
1. Warm up the PF-3200 as described in
the STARTUP section on page 5.
2. Make sure the draining tray is covered
by Aluminum foil and positioned
underneath the glue tank so that the
tank drains into it.
3. Use the 6 mm Allen wrench to open
(Counter Clockwise) the glue drain plug,
which is located on top of the glue tank.
4. Close (Clockwise) the glue drain Allen
screw when the glue stops flowing.
Wait until the draining tray cools down.
Carefully empty the draining tray and
put a new Aluminum foil on it.
Reposition tray and continue draining
the glue tank.
5. Fill the glue tank with new glue up to
the Max. line.
6. Remove the glue drain tray and discard
the cold solidified drained glue.
Note that it's not necessary to drain the
glue frequently if the machine is used
constantly under normal working
conditions. However, in case the glue has
been left unused for a long period of time
with the unit in the "ON" position, and the
quality is found to be unacceptable, use
the glue replacement procedures or call
your authorized dealer.
