(7) While pressing the holder, loosen 2 set-
screws on the upper area of the head
adequately with the 1.5 mm bit (Standard
Accessory Part: 630 116 3659) to detach
the holder from the head.
(a) Carefully loosen 2 setscrews be-
cause the holder pops out upward.
(b) To avoid damaging the tapped hole,
use a hexagon wrench (TONE,
BONDUS) that fits the diagonal di-
mensions.
(8) Detach the miniature stroke bearing (MSB).
(8-1) Detach the MSB shaft and the MSB outer
cylinder.
Pull out the MSB shaft from the upper
side. Use a pair of tweezers to pull out
the MSB outer cylinder from the lower
side.
Do not change the combination of the
MSB shaft and the MSB outer cylinder.
Otherwise, the smooth movement of the
head cannot be expected and the head
may have some leeway.
(9) Detach the upper seal, the collar, and the
lower seal from the MSB outer cylinder.
When the upper and lower seals are
scratched or deformed or foreign
substances have accumulated on
them, replace them with new ones
(630 048 0849).

• Washing of Miniature Stroke Bearing
(1) Wash the MSB shaft and the MSB outer
cylinder with kerosene in the supersonic
cleaner for approx. 5 to 10 minutes.
(a) Do not wash the A-marked area of
the MSB shaft.
Use a cleaning jig to keep the A-
marked area clear of the cleaning
solvent.
If the A-marked area is washed,
the bearings and the spring inside
the shaft will be degreased, short-
ening the longevity of the MSB.
Cleaning Jig
Name : Miniature SB Cleaning
Tray
Jig No. : JG-0128
(b) Alcohol can also be used in place
of kerosene.
In this case, wipe the surfaces of
the MSB shaft and the MSB outer
cylinder with a rag quickly after
washing and grease them up.
(c) Light oil can be used in place of
kerosene.
Right after light oil is used, be sure
to blow air to the MSB shaft and
outer cylinder until they dry out
completely. After that, grease them
up.
(d) Do not leave the MSB shaft and
outer cylinder with kerosene being
adhering to them for a long time.
Otherwise, the longevity of the
MSB will shorten.
