Adjustment
DA3SEC−83−9F0−A0
Sentence No.
When to perform
x When the guide pin does not rise
vertically.
x When the guide pin gets caught on the
insertion hole.
Required tools
x Lever−operated dial gauge
x Allen wrench
Measuring parallelism
1. Turn ON power to the machine. Loosen the
bolt (x 2) and remove the anvil.
2. In manual mode, turn the hand wheel until the
cam shaft is at approximately the 210q position
on the digital sequence timer .
3. Attach the lever−operated dial gauge to the
guide rail (fixed side) on the X− Y table.
4. Set the measuring needle on the side
surface of the guide pin A and bring the
scale reading to “0” (reference point).
=CHECK=
x Do not apply excessive force on the
guide pin shaft when contacting it with
the measuring needle.
x Bring the scale reading to “0”
(reference point ) at a point on the side
surface of the guide pin where the
maximum reading is produced.
5. Move the X−Y table in the x direction by
hand. Set measuring needle on the side
surface of guide pin B and check parallelism
is no more than 0.02 mm.
=CHECK=
If sliding the X−Y table by hand, make
sure the table does not slip in the Y
direction.

Adjusting parallelism
1. Turn the hand wheel to set the digital
sequence timer to 210q.
2. Loosen the bolt (x 1) of the guide pin
upper/lower stopper.
3. Loosen the bolt A (x 1) of the positioning
block.
4. Turn the cam follower holder to obtain the
parallelism.
5. After the parallelism is obtained, retighten
the bolt A (x 1) of the positioning block.
6. Retighten the bolt (x 1) of the guide pin
upper/lower stopper.
=CHECK=
Parallelism may vary depending on
how the bolts are tightened. So be sure
to set the measuring needle on the side
face of the lever−operated dial gauge
when tightening the bolts.

Sentence No.
When to perform
x When parts are dropped frequently
during insertion.
Required tools
x Allen wrench
Checking the guide pin height
1. T urn the cam shaft so that the guide pin is
positioned at the upper limit (210q).
2. Visually check that the guide pin has been
raised approximately at the center of the guide
chuck slit.
