(G) 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.

(H) 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-200 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.
