■External Dimensions
■ Power Supplies
The Brushless Driver must be operated together with a
Power Supply.
Powering the Brushless Driver with the HIOS T-45BL and
the T-70BL Power Supply will insure operation of the driver
at its full capacity.

■Operations
Pre-operating preparation
1. Connect the power cord plug to AC outlet.
2. Turn the power switch to “I”, and check if the LED light
is lit.
If the LED light is not lit, inquiry to the distributor. After
conrmingthattheLEDlightislit,setthepowerswitch
to “0”, OFF.
3. Connect the driver cord to the power source.
4. How to change to “Push” start.
Unscrew the “Switch lever shaft screw” and then take off
the “Switch Lever”. Using sharp parts, such as tweezers,
movetheselectionSWto“P”(push)near“L←→P”mark.
Note: Do not press or hit the SW,
otherwise you may damage
the SW or body case.
lOperating procedure
1. Attach a bit to the driver.
2. Turn on the power switch and set the power output
setting to “1” or “2”.
Output display setting of each power supply
• 2: (30V), 1: (20V)
3. Set the FOR/REV switch of the driver to “FOR” (forward
rotation).
4. Set the tightening torque of the driver by torque adjust-
ment nut.
5. Start the driver.
•After placing the bit end on the screw head, press the
switch lever. The driver will start and the screw will be
tightened on the component.
6. When the screw is tightened with the torque value set
to the driver, the clutch works and the rotation stops
immediately.
7. To loosen the tightened screw, set the FOR/REV
switch to “REV” (reverse rotation). The screw will be
loosened after a few impacts.

Attaching a bit
While attaching or de-
taching a bit, turn off the
power switch or pull out
the driver cord from the
driver to disconnect the
power.
l
BLG-4000
For BLG-4000, pull-down the
“Joint-shaft collar” towards the
body case of it and insert the bit.
l
BLG-5000
For BLG-5000, pull-up the “Joint-shaft collar” and insert
the bit.
l
Checkthatthebitisxedrmly.
l
Use genuine parts for HIOS Shank H4 (∅4) or H5 (∅5).
How to adjust the torque
BLG-4000 has two torque adjustment springs: for high
torque measurement, use the spring installed in the driver
(red spring), and for lower torque measurement, use the
spring attached to the driver (white spring). Use either of
the springs according to work type.
For torque setting, the “Output torque guide” can be used
as a guideline to get the rough torque value.
l
The torque can be adjusted by adjusting the spring pres-
sure in the torque adjustment nut. The torque adjustment
nut can be tightened or loosened by squeezing or relax-
ing it, respectively.
How to adjust the torque
l
BLG-4000
If you already know the screw tight-
ening torque value, by referring to
the guide, set the nut so that the
scale line comes just above the de-
sired torque value scale (1 to 8).

l
BLG-5000
Using the “Allen wrench”, set
the torque referring the torque
adjust scale “1 to 8”.
Try to fasten and find the right
position of the scale.
l
Test the screw tightening with
the set position and until you
find the appropriate torque
value.
Rotation speed
The standard power output of the driver is set to 30V.
Power output setting display
2: 30V, 1: 20V
To decrease the rotation speed according to work type, set
20V as the power output.
Using the screw counter
You can use BLG-4000-OPC or BLG-5000-OPC by con-
necting it to the power supply BLOP-STC3 with screw coun-
ter or to the separate counter BLOP-SC1, BLOP-SC3. For
details of handling, please refer to the operation manual of
the screw counter to be used.

Please check in the usage table.
•Haveyouinstalledthebitproperly?
Check the description in the opera-
tion manual for installing the bit.
•Ifanyof theaboveisnotthe case,
or the problem cannot be solved,
stop operation immediately and con-
tact your distributor for repair.
