Product Information

Product Usage Instructions

To use the BLG Series product, follow these steps:

Step 1: Names of Parts

The BLG Series comes with different models, such as BLG-4000 and
BLG-5000. Each model has specific parts and features. Refer to the
user manual for detailed information on the parts and their
functions.

Step 2: Power Supply

The Brushless Driver must be operated together with a power
supply. It is recommended to use the HIOS T-45BL power supply for
the BLG-4000 model and the T-70BL power supply for the BLG-5000
model. Using these power supplies will ensure the proper operation
of the driver at its full capacity.

Step 3: Torque Adjustment

The BLG Series allows torque adjustment for different fastening
needs. The torque adjustment scale and nut can be found on the
device. Use the provided L wrenches to adjust the torque according
to your requirements.

Step 4: Screw Size Selection

Depending on the model and application, select the appropriate
screw size for your fastening task. Refer to the specifications
table in the user manual for the recommended screw sizes for each
model.

Step 5: Operating the Driver

The BLG Series drivers have different operating modes, such as
lever start, push start, or with built-in screwdriver
functionality. Depending on the model, use the corresponding switch
or lever to start or stop the driver. The driver rotates when the
switch lever is pressed.

Note: For detailed instructions on operating each specific
model, refer to the attached operation manual for BLG-BC1,
BLG-ZERO1 series.

For any further assistance or troubleshooting, please refer to
the complete user manual provided with the product.

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 confirming 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. Do not use the screwdriver with the switch lever shaft screw removed. It may cause a malfunction.
l Operating 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 adjustment 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 detaching a bit, turn off the power switch or pull out the driver cord from the driver to disconnect the power.

Insert bit

Insert joint shaft collar in the driver for BLG-4000

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 fixed firmly.

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 relaxing 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).

Torque adjustment nut can be turned and moved manually with this ring

– 6 –

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 connecting it to the power supply BLOP-STC3 with screw counter or to the separate counter BLOP-SC1. For details of handling, please refer to the operation manual of the screw counter to be used.

l Before requesting our repair service, troubleshoot according to the following table:

Problem

Cause and solution

Bit falls off or cannot · Are you using the bit suitable to your

be installed

model?

Please check in the usage table.

· Have you installed the bit properly?

Check the description in the operation manual for installing the bit.

· If any of the above is not the case, or the problem cannot be solved, stop operation immediately and contact your distributor for repair.

Weak force, cannot tighten the screw sufficiently

· Are you using HIOS genuine parts and specified springs?
· Check the torque value again in the “Output torque guide” for the driver.

· If any of the above are not the case, or the problem cannot be solved, stop operation immediately and contact your distributor for repair.

Driver does not rotate. · Check the power supply.

Refer to the “Pre-operating preparation” on this paper.

· If the above is not the case, or the problem cannot be solved, stop operation immediately and contact your distributor for repair.

l Use the HIOS torque meter to check the screw tightening torque. · Use HP series for electric driver torque setting. · Use HDP series for measuring screw loosening torque and retightening torque.
