When using electric tools, the following basic safety precautions should always
be adhered to in order to reduce the risk of fire, electric shock or personal injury:

READ ALL INSTRUCTIONS
1. Keep Work Area Clean.
Cluttered areas and benches can result in injuries.
2. Consider Work Area Environment.
Don’t expose tools to rain. Don’t use tools in damp or wet locations.
Keep work area well lit.
Never use the tool in an area with dangerous objects present. (gasoline,benzene, thinner, gas glue, etc.)
3. Secure Work.
Use clamps or a vice to hold work piece. It’s safer than using your hand and it
frees up both hands required to operate the tool.
4. Guard Against Electric Shock.
Prevent body contact with grounded surfaces such as pipes, radiators, ranges
and refrigerator enclosures.
5. Keep Away From Children.
Do not allow visitors to use the tool. All visitors should be kept away from workarea.
6. Store Idle Tools.
When not in use, tools should be stored in a dry and high or locked-up place outof reach of children.
7. Do Not Force The Tool.
The tool will operate better and safer at the rate for which it was designed.
8. Remove Adjusting Keys And Wrenches.
Make a habit of checking to see that keys and adjusting wrenches are removed
from the tool before turning it on.
9. Use The Correct Tool.
Use the tool for the correct work for its rated power and design.
10. Dress Properly.
Do not wear loose clothing or jewelry as they can be caught in moving parts.
Wear protective headwear to contain long hair.
11. Use Safety Glasses.
Also use a face or dust mask if the operation involves dust.
12. Do Not Abuse The Cord.
Never carry the tool by its cord or pull it to disconnect from the power outlet.
Keep the cord away from heat, oil and sharp edges.
13. Do Not Overreach.
Maintain proper footing and balance at all times.
14. Maintain Tools With Care.
Keep tools sharp and clean for better and safer performance.
Follow instructions for lubricating and changing accessories.
To use the tool for an extended period of time safely, perform periodical
inspections on the tool and if damaged, request repairs by authorized service
facility.
Keep hands dry, clean and free from oil and grease.
Inspect extension cords periodically and replace if damaged.
15. Disconnect Tools.
When the tool is not in use, such as attaching and removing the bit, changing
the Carbon Brush, inspection or cleaning, disconnect the tool from the power
outlet.
16. Avoid Unintentional Starting.
Ensure that the switch is off when plugging in.
Do not carry the tool with finger on the switch.
17. Stay Alert.
Always remain vigilant., use common sense, and do not operate the tool when-2-you are tired.
18. Check Damaged Parts.
Before using the tool further, a damaged protective cover or other parts should
be carefully checked to determine whether the tool will operate correctly andperform as designed. Check the alignment, binding, damage, and mountingof any moving parts. Protective covers or other parts that are damaged should
be properly repaired or replaced by an authorized technician or service facility
unless otherwise indicated elsewhere in this instruction manual.
19. Extension Cords For Outdoor Use.
When the tool is used outdoors, use only extension cords marked for outdoor
use.”

CAUTIONS IN OPERATION1. This Screw Driver is integral unit consisting of Screw Driver parts and cordparts.
If there are any problems, do not disassemble the tool.
Stop operations and have the tool repaired immediately.
2. Never lubricate the tool with aerosol oil or similar lubricants. Doing so may
result in expensive repairs.
3. Do not drop, hit or abuse the tool. Doing so may cause problems such as
cracks or damage.
4. Never use chemicals to wipe the body cover.
5. Use only under the correct voltage (220-240V).
Never use with the higher voltages.
6. Do not pull the AC cord when unplugging from the power outlet.
Doing so may cause the wire to become severed.
7. To avoid dragging the AC cord on floor, use the Spring Balancer to hang theAC cord.
8. For safety use, do not set the torque adjusting nut higher than 10 on thetorque adjusting scale.
9. Use the tool intermittently: (ex: 0.5sec.on/4.5sec.off )10. Do not tighten more than 720 tapping screws in an hour.
11. This tool is not for tightening wood screws.
12. Never change the forward ←→ reverse direction immediately while the motoris running.
13. If the tool is not being used, set the start switch and Forward/off/Reverse
switch to “OFF” position and unplug the AC cord plug.

GROUNDING INSTRUCTIONS
The tool should be grounded while in use to protect the operator from electric
shock.
The tool is equipped with a three-conductor cord and two-prong groundingtype plug to fit the proper grounding-type receptacle.
The green (or green and yellow) conductor in the cord is the grounding wire.

SAVE THESE INSTRUCTIONS
We thank you for your purchase of HIOS Electric Screw Driver.

SUMMARY
The VB Brushless Driver uses a high-performance brushless motor for
maintenance free and reliable screw fastening operations. A clean working
environment can be achieved as the driver does not output any harmful carbon
particles.
There is little heat generated from the motor, meaning there are very few
heat-related problems when using the driver for extended periods of time.
The brushless motor is the optimum choice when considering the working
environment and work quality.
The VB Brushless Driver case is made of anti-static plastic to prevent thegeneration of static electricity.

1. Attach the bit to the driver.
2. Set the fastening torque for the driver unit with torque adjusting nut.
3. Turn the FOR/OFF/REV switch to OFF and connect thedriver power plug to an AC power outlet.
CCW
4. Turn the switch to either FOR or REV, start the driver,and check the direction of rotation.
CWCaution
When starting the driver, it is extremely dangerous topinch the bit end with your fingers or push on the bit end. Never touch therotating bit.
5. Operate the clutch until the screw is tightened to the set torque value, thenstop the driver.
6. When loosening a tightened screw, turn the FOR/OFF/REV switch to REV, andloosen in the reverse direction.
(If the screw does not come loose, tighten the torque adjustment nut to increase
the torque before trying again.)

Torque Adjustment Procedure
1. R emove the torque adjustment protective cover.
2. I f the screw fastening torque is already known, set
the torque adjustment nut to the appropriate Level
3. Operate the driver so that the screw is tightened, andcheck the tightness of the screw after the driver stops
automatically.
4. I f the screw is too loose, slide the torque adjustment
nut upwards to increase the fastening torque. Repeat
this process to determine the appropriate tightness.

The Protective Covercan be removed fromthe frontring by
twisting it right.

Protective CoverAttaching the Bit
CautionWhen attaching the bit, always ensure that the driver FOR/OFF/REV switch is set
to “OFF”, or that the driver power plug has been removed from the AC power
outlet so that there is no power within the driver.
To install the bit, pull the joint shaft collar at the end of the driver upwards andinsert the bit. Check that the bit does not come loose after you have inserted it.

Check the items listed in the table below, and if a malfunction is found, contact
your store of purchase of our company.
Always include your warranty card when sending in the driver for repairs.
Symptoms

Cause and Treatment

The driver motor sometimes
fails to operate- Is the cord severed?

The driver is weak and cannot
tighten screws sufficiently- Is the torque setting at the correct
position?

Stop any work and request repairs.

Refer to the output torque guidance.
