Due to the high rotating speed, the tightening torque of α-series screwdrivers may differ
from the setting depending on the screw or board materials being used.

Precautions on Use(1) Do not drop it or otherwise subject it to excessive
shock.
(2) Be careful not to splash water or oil.
(3) Use HIOS power supplies units. We are not responsible for any malfunctions or troubles caused by using
power units other than specified.

4. How to Operate
1. Select bit. Push down the joint shaft collar at the topof the screwdriver and insert the bit.
2. See the torque chart and match it with you torqueapplication.
3. Select correct spring by color for corresponding torqueaccording to the torque chart.		Example:		 For getting automatic shutting at 8 kgf.cm with CL6500 you could use either spring Y or W. With Y
spring the torque adjusting nut should be set at #3
position on the driver scale; with W spring at #5.
For torque over 11 kgf.cm, however, only Y spring isapplicable as can be seen on the chart.
4. Plug in the power supplies and check red power
indicator. If it is not on, check fuse on power pack or
AC supply.
5. Connect the cord of driver to power supplies. Make
sure groove on plug lines up with projection on socket.
Tighten knurled ring.
6. Set torque adjusting nut at proper position on driverscale conferring with torque chart.
7. For testing purpose, drive one screw until driver stops
automatically.
8. Check the fastened degree of the screw with a torquewrench. (For this checking, HIOS torque meter HDPor HDM Series recommended.) If found too high or
too low, adjust the position of nut for further testing.
9. Once you get best result keep Nut there intact andyou will enjoy accurate repeatability of fastening atsame torque.
10. The torque adjusting nut of CL-6000, CL-6500, CL7000 may be locked after the position is determined.
Holding Torque Adjusting Nut, rotate only the metal
band around it until a tapped hole is uncovered. Installa M3 x 3 set screw there and tighten it. Return bandto original position.

● The torque adjusting nuts of the CL-3000, CL-4000,SS-3000, SS-4000, α-4500, α-5000 can be locked
by aligning the red mark on the outer casing with any
one of two vertical grooves (or three grooves for thestandard-type screwdriver) of the bolt located nearest
the torque adjusting scale. To change the position, liftand turn the nut outer casing.

▶

▶

● The CL-2000 (SS-2000) Electric Screwdriver have
‘Double nut system’ (Nut fixing ring and Torqueadjusting nut) to avoid loosening from shock orvibration to the driver. To adjust those two nuts,
follows ① to ③ steps below.
① At first, stop the Nut fixing ring uppersurface to fit the graduation, if youwant to adjust.
② Then turn the Torque adjusting nut so
as to push up the Nut fixing ring.
③ Lastly, to avoid the loosening of the‘Torque adjusting nut’ strongly fasten
the Nut fixing ring’ by holding the‘Torque adjusting nut’.

5. Push-to-Start Type
Both the models of Driver have Push-to-Start type that isdesigned to start by causing a proper thrusting pressure
on the bit in place of pressing the Switch Lever by theforefinger. Drivers of this type are identified by theadditional sign PS following the principal Push-to-Start typemodels. The PS type, therefore, has no lever for starting.
All other functions remain same as the principal type.
Users of this type is specifically cautioned to disconnect
the cord to shut off power when handling the Quick Change
Collet for replacing bit to avoid danger from surprising
starting.

56. Power Supplies
The power pack for CL Drivers requires two basic functions: (1) to convert local AC power to lowered DC Powerand (2) to shut off the power by automatical reaction to thepulse emitted from the Driver at the moment the torque atwork reaches the regulated limit. The function (2) can be
performed, if so opted, by a ready-made unit called Control
Box CB-105 installed separately from the unit for the function (1).

direction only, keep one pair of the terminals idle.
● When connecting main wires to the terminals, besure to connect the red wire to (+) and the black wireto (-).
1. Connect the branch wire to the main wire at regularintervals. Use a U-Element for connection. You canconnect wires without stripping off the wire coating.
2. Insert the main wire ① into the groove by widening
the lower split (opening) of the U-Element.
3. Fully insert the branch wire ② into the upper hole until
it stops.
4. Insert a U-shaped element ③ (the comb-shapedmetal part) with a pair of pliers to make it flush withthe plastic body. Only the coating is broken; bothwires still connected.
5. Put an insulation cover ④ on the element and snap it
shut.
6. The connected branch wires have plug receptaclesat their other ends. Connect the control box plugs tothese plug receptacles.

8. How to replace carbon brushes
1. It is recommended to replace the pair of carbon
brushes to maintain performance when worn out toabout half the length.
2. Carbon brush caps have a slot.
Unscrew them with a flat tip driverto open them. Be careful not toallow the carbon brush inside tojump out as it is kept there underspring pressure.

CONCAVE

3. With the mini-type screwdriver,
one of the carbon brush covers
is located under the switch lever,therefore, the switch lever must beremoved before reaching it. Turnthe hexagonal head of the axis
supporting the switch lever, thenthey can be removed.
4. Replace the worn carbon brushes with new pair. Notethat the end surface of the carbon piece is not exactly
flat but of slightly concave face, so see to that thecarbon piece is placed in the correct direction wheninserted into the holder to have its curved face makesmooth meeting with the rotation of the deep innercommutator. Screw the cap tightly.

* Since α-series screwdrivers feature high-speed rotation,
their tightening torque may differ from the setting values
depending on the various conditions of screws and parts
materials.
