the fastening torque as follows.

2. Loosen and remove the screw that secures ring.
3. Rotate the ring in the front of the tool by hand so that a
hole can be seen below the ring.

Status
This function works when the tool has
reached the preset fastening torque
and normal tightening has been com-
pleted. This helps overtightening to
be avoided.
For approximately one second after
auto-stop fastening, the tool does not
start even if the switch trigger is
pulled.
Insufficient fastening has been per-
formed when the switch trigger has
released before reaching the preset
fastening torque.
This indicates the appropriate time to
replace the battery cartridge when
the battery power becomes low.
This function works when the battery
power is almost used up. At this time,
tool stops immediately.
This function works to check the
proper operation of the LED indicator,
lamp and beeper when a battery car-
tridge has been inserted into the tool.
This function works when an abnor-
mal drop of the battery voltage occurs
for some reason, and the tool stops.
This function works when the temper-
ature of the controller goes up very
highly, and the tool stops.
This function works to avoid the tool's
immediate start upon insertion of bat-
tery cartridge into the tool with the
switch trigger being pulled.
The tool automatically stops without
the clutch working when exceeding
the fastening capacity limit.
