*:#Same features as HR4000C
Efficiency
The highest efficiency in this class.
All enclosure is made of resin. *
Even if the bit touches the electric wire
inside the wall,an electrical shock may
hardly hit on the operator.
Push-to-strike system
Bit does not jump arround.
Efficiency and endurance
are improved.
* For pointing job, you can use
* Large change lever
Easy to change opeation mode
between " Hammering only "
and " Rotation with hammerig "
New torque limitter system
Roller clutch system
(#HR4000C:Ball clutch system)
for coping with the higher power,
and for improvement of endurance.
* Large trigger
No fatigue at finger after
long operation.

Note 1) When inserting Tool holder A, use care that O ring 36 mounted on
tool holder A may not exceed the hole for holding the pin 10 of tool holder B.
(Reason : O ring 36 may be cut off.)
Note 2) O ring 36(Pn:213522*3) to be mounted on the Tool holder A is different
from the O ring 36(Pn:213510*0) to be mounted on Cylinder 40 and crank
cap.
O ring to be mounted on Tool holder A is the one of heat resistanse
and is coated with green paint for identification.

Taking out cylinder 40
Cylinder 40 is pressed into Crank housing.
To remove Cylinder 40, using gear puller 1R-213 is recommended.
(See the figure 17.)
If the repair tool IR-213 is not avarable,slightly hit
teh crank housing against the firm table several times
in a straight inte to remove cylinder 40.
Since strongly hitting it may damage of bent the crank
housing, please use the repair tool IR-213.
