the cap 37 as shown on the right figure.
Pull out the change ring cover.
Strongly pull out the change ring to disconnect it. If hard to
disconnect, place the minus screw driver between clearance
of leaf spring, expand the leaf spring just like twisting the
driver, and then pull out it. It is fixed by steel ball and leaf
spring.

2-1. Disassembling of barrel
Remove the hexagon socket bolt M5x20 and then remove
the barrel.
Use the arbor press to press the top of tool holder to
remove it.
2-2. Assembling of barrel
Assemble in a way that the trace of pusher pin shown on
the right figure comes at name plate side.
3-1. Disassembling of impact bolt
Use the screw driver to shift the impact bolt in the direction of tool holder edge as shown on the bottom-
right figure.(in the direction of arrow 1)
Use the resin hammer to slightly hammer the tool holder as shown on the bottom-right figure to remove
the four points of steel ball 5 and 6.
Use the sharpened-edge tool like an eyeleteer to pull out
the O ring 11 as shown on the bottom-right figure. For
easy disconnection, use the eyeleteer while 5 mm around
of sharpened-edge tool edge is being bent by 90"around.
Use the driver edge to disconnect(push) the impact
bolt.(in the direction of arrow 2
3-2. Assembling of impact bolt
Use the screw driver to insert the impact bolt into the tool
holder.
Use the sharpened-edge tool to insert the O ring 11 into the
groove of the tool holder. Move the impact bolt in the direction
of arrow to check if O ring 11 cannot be disconnected.
Before placing the steel ball 5 and 6 in the tool holder, grease
into the hole so that the steel ball cannot drop and the tool
holder can be easily set.
4-1. Disassembling of torque limiter
Use the circle clip plyer to disconnect the circle clip(shaft)S-
26 and then remove the spiral bevel gear 33, clutch cam and
compression spring 31.
If hard to disconnect the parts, shift the flat washer 26 away
from the circle clip groove since it is housed in said groove.
4-2. Assembling of torque limiter
Use care of direction of clutch cam when assembling the
torque limiter.
Engage the protruded portion with the spiral bevel gear 33
while supporting the compression spring 31 by holding the
dent face.
5-1. Disassembling of crank
To disassemble the handle set, disconnect the two points of pan head screw M5X25 connected on the
crank housing complete and then disconnect the tapping
screw PT5x25 connected on the motor housing complete.
To disassemble the motor housing complete, disconnect the
hexagon holed bolt M5x45 connected on the gear housing
complete and crank housing complete.
Separate the crank housing from the gear housing.
Use the lock nut wrench 28 to disconnect the crank cap.

Push the crank shaft from the crank cap side to pull out it
as shown on the bottom-right figure.
Since the ball bearing 6001, ball bearing 6002, helical gear
43 and helical gear 29 are inserted by pressing, use the arbor
press to pull out them.
At this time use care not to miss the flat washer 8.

For assembling, follow in the reverse order against
disassembling.
6-1. Replacing of armature
Disconnect the holder cap from the motor housing complete
to pull out the carbon brush.
Use the resin hammer to disconnect the one body of armature
complete and gear housing complete from the motor housing
complete.
Pull out the armature complete while holding the gear
housing complete.
6-2. Assembling of armature
Assemble the ball bearing 6000 and oil seal 12 on the gear
housing complete before inserting the armature.
Note) If one body assembled with ball bearing and oil seal is
inserted into the armature, the oil seal cannot be
completely inserted and it may cause oil leaking.
