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.

squashed following insertion.
x When parts are dropped frequently
during insertion.

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.

Adjusting perpendicularity
1. Loosen the bolt B and disengage the arm.
Then turn the shaft to measure the
perpendicularity.
(Adjust the perpendicularity within 0.1 mm.)
=CHECK=
As the bolt B is also fixed with cotter, tap
it lightly to release after loosening the
bolt.
(Be careful not to drop the arm after the
cotter released.)
Adjusting height
1. Disengage the bolt A (x 2).
2. Move the pusher rod up/down so that the gap
between it and the PC board (t = 1.6) may be
between 0 and 0.5 mm.
=CHECK=
When lifting the pusher rod, loosen the
bolt B to raise the pusher and then
retighten the bolt B. Check that the
perpendicularity does not change when
loosening the bolt B.
