5.6 Insertion Head Guide Parallelism Check and
Adjustment
DA3SEC−83−8N0−A0
Sentence No.
When to perform
x When parts leads do not readily
slip into the guide chuck.
x When insertion errors occur
frequently.
x Allen wrench
x Box wrench
x Lever−operated dial gauge
Required tools
Parallelism check
1. Remove the spring from the insertion
head.
2. Set the machine to manual mode and turn
OFF the HEAD SWIVEL LOCK. Turn the
hand wheel until the cam shaft is at the 0q
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 insertion head.
5. Move the X−Y table in the X direction by
hand.
=CHECK=
If sliding the X− Y table by hand, make
sure the table does not slip in the Y
direction.
6. Check parallelism of the insertion head
(inserting chuck) against the guide rail is
between 0.05/20 − 30 mm.

Adjusting parallelism
1. Loosen the bolt on the insertion head drive unit.
Then, while pressing down on the arm by hand,
turn the cam follower guide until the correct
degree of parallelism is obtained.
2. After making adjustment, tighten the arm bolt to
check for the parallelism again.
=CHECK=
Be careful not to change the arm height when
tightening the arm bolt because the arm
moves up/down easily during adjustment.

Perpendicularity/Height Check/Adjustment
DA3SEC−83−8PO−A0
Sentence No.
When to perform
x When parts are often slanted or
squashed following insertion.
x When parts are dropped frequently
during insertion.
x When insertion errors occur
frequently.
x Allen wrench
x L−square
x Lever−operated dial gauge
Required tools
Perpendicularity check
1. Remove the guide chuck and press the dial
gauge against the side of the insertion pusher
to make sure the perpendicularity is within 0.1
mm.
=CHECK=
When lifting the pusher with your finger,
make sure that the pusher moves
smoothly.
(If not so, remove the spring pin from the
pusher and ream the inside of the pusher
rod with a straight reamer between I6.0
and I6.02.)
Height check
1. Using the hand wheel, set the sequence timer
to 310q (pusher lower limit) and make sure the
distance between the pusher and PC board is
between 0 and 0.5 mm.
