6-3 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.
• Turn the knob counter clockwise to decrease the nipping pressure when
nail head spine occurs or making thicker books.
6-4 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 redline in the tank while the application
drum is rotating. This will prevent glue from spilling out of the tank.
Glue Replacement
1. Warm up the DB-250 as described in the STARTUP section on page 5.
2. Make sure the draining tray is warped by Aluminum foil and positioned
underneath the glue tank so that the tank drains into it.
3. Use the 6 mm Allen wrench to loosen (Counter Clockwise) the glue drain Allen
screw, which is located on top of the glue tank.
Do not attempt to remove the draining tray until the glue cools down.
4. Close (Clockwise) the glue drain Allen screw when the glue stops flowing.
5. Add new glue to the glue tank Be sure to keep the glue level not going over the red
line.
6. Remove the glue drain tray and discard the cold 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.

APPENDIX
A - Troubleshooting Guide for Spine Adjustment
Note: Before you perform the spine adjustment, try to use the following methods
to correct it.
(A) Round / hollow middle through the spine
(1) Increase the certain quantity of hot-melt glue by the glue meter.
(2) Turn VR knob clockwise to increase the nipping pressure.
(B) Nail head through the spine:
(1) Decrease the certain quantity of hot-melt glue by the glue meter.
(2) Turn VR knob counter clockwise to decrease the nipping pressure.
There are two types of the spine adjustment: A1- Clamp Spine Adjustment and A2 Nipping Plates Adjustment. In order to make good spine of books, we suggest that
you can use the clamps / the nipping plates to hold three different amount of inner
pages. For example: 25, 150 , and 300 pages or 1/8” (3 mm), ¾” (18 mm), and 1 1/2”
(40 mm) in thickness of book block and do the adjustment accordingly.
• Clamp Spine Adjustment:
Use the “CLOSE” button to hold one amount of inner pages on the clamps. Then
check if there is no gap between the nipping plate surface and inner pages as shown
below. Otherwise you need to do the adjustment for the clamps. Repeat the same
procedures for different amount of inner pages.
• Nipping Plates Spine Adjustment:
Use the “MOTOR 2” of the “TEST2” to hold one amount of inner pages on the
nipping plates. Then check if both nipping plates can evenly hold the inner pages
without off the centerline as shown below. Otherwise you need to do the adjustment
for the nipping plates. Repeat the same procedures for different amount of inner pages.
Centerline
Nipping plates
LL: Left corner of left-end spine
RL: Right corner of left-end spine
LR: Left corner of right-end spine
RR: Right corner of right-end spine
Good spine should be: LL = RL = RR = LR Four corners of the spine

(1) Increasing certain quantity of the hot-melt glue by glue meter, then make
some books to see if the spine has been improved on both sides.
(2) Slightly turn the VR knob clockwise to increase the nipping pressure, then
make some books to see if the spine has been improved on both sides.
(3) If (1) or (2) can not improve the book spine, you have to do the adjustment
for the clamps. Slightly loosen the bottom lock nuts, then gradually tighten
the bottom screws of the clamps until there is no gap between the spine and
the nipping plate surface when you close the clamps. Make some books to
see if the spine has been improved on both sides.

(2) Slightly turn the VR knob counter clockwise to decrease the nipping
pressure, then make some books to see if the spine has been improved on
both sides.
(3) If (1) or (2) can not improve the book spine, you have to do the adjustment
for the clamps. Slightly loosen the upper lock nuts, then gradually tighten the
upper screws of the clamps until there is no gap between the spine and the
nipping plate surface when you close the clamps. Make some books to see if
the spine has been improved on both sides.

A2 - Nipping Plates Spine Adjustment
One side round and one side square
LL ≠ RL RR ≠ LR
OR OR
You have to adjust the nipping plates.
Push each side of nipping plate to find which side is loosing or too tight. Then
slightly loosen all the nipping plate adjustment screws on each plate. Then use the
nipping plate screws to do the fine adjustment until both sides have the same tension
that can be pushing smoothly. Then use the “MOTOR 2” of “TEST2” to hold the
inner pages to check if both nipping plates can evenly hold the inner pages without
off the centerline as shown below. Having verified the nipping plate position, you
can tighten the nipping plates. Make some books to see if the spine has been
improved on both sides.
