Introduction
Thank you for purchasing the BLF series, BLFQ series or BLFR series of the brushless screwdrivers forautomatic operation.
Before using, please make sure to read this instruction manual well and use the tools properly.
Please keep this manual in a safe place after reading.
NOTE

The screwdrivers have warranted its ability within controlled torque range.
However, please consider the following situation when installing the tools in customer’s operation.
* If there is any inclusion (ex. Universal joint) at joint part between screwdriver and bit, output torque would bebadly affected by some conditions (ex. inertia or resistance). Please select proper model considering torque with amargin.

Features◦Our brushless screwdrivers are durable and enable stable screw fastening.
◦The durability has been improved by simplifying the control circuits.
◦There are two types of the vacuum pick up screwdrivers.
The BLFQ is a standard vacuum pick up screwdriver.
The BLFR is for deeply recessed screws.

04

Cautions After Introducing the Screwdriver and the Power Supply
Rotation speed of the screwdriver◦The rotation speed is different for forward and reverse rotations. Please refer to the values on thespecification of the screwdriver and the torque guide table only as rough guidelines.
◦The rotation speed is measured without load. Please note the rotation speed varies when the set
value is 27 or more.
The controlled torque values are measured with the combination of a HIOS Torque Meter HP-100
and a Fidaptor*. The values during your work are not always the same as the values in the table.
Please refer to the values in the table only as rough guidelines.
* F or measuring torque with the screwdriver, use a fidaptor (accessory of HP-100), which reduces and absorbs
the inertia generated at stoppage and has the ability to reproduce near-screw-fastening conditions to detect
the torque when the clutch fires during rotation of the screwdriver. Also, please use a dedicated torquemeasuring instrument, HM Series, which can measure output torque of the screwdriver after it is installed.

Cautions When Installing the Screwdriver◦If you want to install screwdriver facing up, please contact us.
◦About the speed setting for screwdriver descending
If the descending speed of the Z-axis is faster than the screw fastening speed, screw floating may occur due
to overloaded tightening. Set the descending speed of the screwdriver appropriate for the screw fastening.
◦Consider the stiffness against Z-axis including the installation board of the screwdriver.
NOTE◦Please select Z-axis based on the following formula:
Screwdriver weight + Installation angle weight = Tightening reaction force
Make sure to install the screwdriver with the above condition satisfied. (Please contact us for details.)◦Please determine the thickness of the installation board tolerable with stiffness and reaction force.
Guideline for the installation board thickness
・BLF-2000/BLF-5000: 8 mm or more
・BLF-7000 Series: 10 mm or more◦If the screw fastening cycle is short and constant torque is always required when a tapping screw is fastened, it
is necessary to check the required torque level by using an actual machine. In such case, feel free to contact us.
◦If the torque is high, presume that the reactive force against the screwdriver is strong and thestiffness of the installation flange and Z-axis will impact on the screw fastening.
◦Even if the above setting conditions are satisfied, overload may occur. In such case, review the
installation conditions.
◦The flange and the main body of the screwdriver are fixed with left-handed screws.
◦For the load in the direction to the axis of the screwdriver (thrust direction), design using a damper
mechanism.
* Dampers with simple shock absorbers are available from HIOS. Consider using them if appropriate.

Cautions when using a universal joint◦Offset from the center axis causes overload by twisting of the output axis. Incomplete fixation may
cause power loss, overload on the screwdriver or twist, and may decrease the output power of thescrewdriver.
As a result, incomplete tightening may occur even if the output torque is a standard value.
◦When using a universal joint, make sure that a rotational load is not applied to the bit.
NOTE

When using a universal joint, output torque of the screwdriver and the actual output torque may
be different due to inertia. Make sure to measure both torque of the screwdriver and the actual
output torque.
◦When a universal joint is installed, make sure not to overload in the direction of the axis of thescrewdriver (thrust direction), and not to damage the workpiece and the screw bottom.
Guidelines for the load limit
BLF-2000: 3kg or less
BLF-5000/BLF-7000 Series: 5kg or less◦When a universal joint or fixture is installed under screw fastening conditions, implement testtightening several times.
1. Is it fastened at the set torque?
2. Is the rotating speed of the screwdriver constant?
3. Isn’t the bit wobbling?
4. Is there any abnormal noise...etc? Check these prior to the final tightening.
◦When using a universal joint, make sure the bit turns by hand.
<Example>

1. For the thickness of theinstallation board of the backboard, appropriate thickness
under the installation
conditions should be kept
when fixing.

3. When connecting an Angle to the Z-axis,
fix it firmly. If it is loosely fixed, it may cause
problems such as overload.

Precautions◦Please read this instruction manual thoroughly before use to ensure proper operation.
◦On any commercial power supply, install a ground-fault interrupt breaker and safety circuit breaker.
◦Connect the power supply to ground and use only the rated voltage.
◦Please consider every condition such as power loss and inertia due to the Joint Shaft part, etc.
from the body to the bit of the screwdriver. Make sure to select the screwdriver that well meets therequirements.
◦In case a universal joint or jigs are used, the actual output torque values may be different from thecorresponding torque values displayed on the specification table.
◦Please confirm that the screwdriver and the power supply are the right combination.
◦The overload protection will be activated when the screwdriver is locked or has become
overloaded. If the screwdriver is overloaded repeatedly, the maximum ratings of the power
supply or screwdriver may be exceeded. If the screwdriver becomes overloaded during normal
operation or begins to malfunction due to developing excessive heat, stop the ongoing operation
immediately, turn the main power switch off, remove the power cable, and contact our service
department or HIOS distributor for repairs.
◦When fastening screws on workpieces constructed of plastics susceptible to static electricity
build-up, operation should be done after static electricity has been discharged. If the work pieces
that have not been properly discharged, static electricity may flow up through the end of the bit,causing malfunctions of the tools.
◦Do not disassemble or modify the tools in any way, as doing so may cause malfunctions of the tools.
Such malfunctions are not covered by the HIOS warranty and repairs may be refused.
◦The operating environment for the screwdriver should be between 5̊C and 40̊C with relative
humidity of 80% or less (there should be no possibility of condensation).
◦Do not drop the tools or subject it to mechanical shocks.
◦Always hold the plug when inserting or removing power cables or the driver cords into or fromsockets.
◦Do not drag cords or cables, subject them to oil or to sharp edges, or place them under heavy
objects.
◦If the tools will not be used for a long period of time, turn the main power switch OFF and unplug itfrom the service outlet.

Suction (Vacuum) Attachment BLFR series
OutlineThis attachment is designed to be installed in robots and makes torque adjustment and bit
replacement easier. Because replacement is not required, it is optimal for robots.
This attachment can be effectively used for difficult screw fastening positions including deep holes
where normal attachment interferes with fastening.
NOTE◦If you use the BLFR screwdriver in a reverse rotation, be careful about loosening the bit because
it is screwed on.
Features of BLFR screwdriver◦The BLFR Mouthpiece is double mouthpiece structure with a spring. There are 2 types of those.
One is a self-adjustable inner mouthpiece type.
The other one is a self-adjustable outer mouthpiece type.
There is another special mouthpiece that does not touch work piece which prevents work piecefrom damaging.
◦Compared with the existing HIOS Mouthpiece, the ultimate vacuum of the BLFR Mouthpiece ishigher which helps to reduce vacuum screw errors.
◦The edge of the BLFR Mouthpiece touches parallel to the screw head which improves uprightnessof the screw.
◦The long Bit Holder prevents cross threaded screws.

space.

●Comparison in case of screw fastening at a slant:
e.g.) 4mm screw is tightened with the pilot hole deviated from the straight position by 1.5mm.
