HOW TO USE
■OPERATION
1. Insert the Bit into the Joint Shaft Collar of the
ScrewDriver.
2. Turn the Torque Adjusting Nut and adjust the tighten-
ing torque.
3. Make sure the Forward/Off/Reverse Switch is in the
"OFF" position.
4. Insert the AC Plug into the AC 220 -240V socket.
(AC100V for VZ-1510, VZ-1510PS)
5. Set the Forward/Off/Reverse Switch at the "FOR-
WARD" position.
(Caution)
Whenever the direction of rotation is changed, make
sure the Forward/Off/Reverse Switch is in the "OFF"
position.
6. Fit the Bit to the recession of a screw head, then
push the Switch Lever to start the motor.
•Push to Start System ··· Motor automatically starts
by pressing the tip of Bit against the recession of a
screw head.
7. The clutch will automatically stop the rotation of
motor when the torque reaches to the fixed value.
Release the Switch Lever to put the Bit off the screw.
By the repeat of these operation, screw is tightened
continuously.
•Push to Start System is automatically released by
moving the Bit away from screw head.
8. To loosen the tightened screw, turn the Forward/Off/
Reverse Switch to "REVERSE" position.
•When the screw can not be loosened, tighten up
the Torque Adjusting Nut.
■ Push-to-Start Type
Both the models of Driver have Push-to-Start type that is
designed to start by causing a proper thrusting pressure on
the bit in place of pressing the Switch Lever by the forefin-
ger. Drivers of this type are identified by the additional sign
PS following the principal Push-to-Start type models. 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.

10
Attaching the driver bit
Always move the driver normal/
reverse selector switch to the “OFF”
position, or remove the drive power
plug from the power outlet so that it
is not powered when attaching or
removing driver bits.
Please take note that if the push-
start driver is powered, even the
slightest push can cause the driver
to rotate and cause unexpected
injuries.
•To attach the driver bit,
push the joint shaft
collar down towards the
driver body and insert
the driver bit. Check that
the driver bit is firmly
locked after it has been
attached.
•The VZ-1812 series and
VZ-3007 series has a
chuck to suit both the
HIOS shank H5 (Ø5) and the 5 mm wide hexagonal

■ How to adjust the torque
The Torque Adjusting Scale does not indicate the torque
value directly. The torque value of each scale is indicated
by the Approximate Guidance of Output Torque on P.14.
Sometimes, there may be difference between fixed value
and actual tightening torque by the condition of screw and
materials. Please use this Approximate Guidance to get
the approximate torque value.
(1) Referring the Approximate Guidance of Output
Torque, decide the position of Torque Adjusting Nut
in the Torque Adjusting Scale.
(2) Rotate the Torque Adjusting Nut and set the right
upper of decided graduation.
(3) Start the motor and tighten the screw. Check the
condition of tightening screw.
(4) If the tightening is not enough, tighten up the Torque
Adjusting Nut.
In case of opposite, loosen it. Repeating the adjust-
ment, find the most suitable point.
•The VZ-1510 (VZ-1510PS) Electric Screwdriver have
‘Double nut system’(Nut fixing ring and Torque
adjusting nut) to avoid loosening from shock or
vibration to the driver. To adjust those two nuts,
follows (1) to (3) steps below.
(1) At first, stop the Nut fixing ring
upper surface to fit the graduation,
if you want 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.
■We recommend to use the HIOS Torque meter
Tools to set the torque of Screw Driver or to
check the torque of screw. (HP, HDP series)
•To set the torque of Electric Screw Driver or to check
the measurement tools (Torque Driver, etc.) ··· HP
Type
•To measure the loosening torque or tightening torque
··· HDP Type

13
■How to change the Carbon Brush
(Caution)
Whenever changing the Carbon Brush, AC plug should be
unplugged.
•Unscrew the slotted Carbon Brush Cap by Slotted
Screw ( - ) Driver and remove it.
•When the Carbon Brush Cap is changed, pay
attention to the direction of brush surface (concav-
ity). Insert the Brush to fit its surface to the
Commutator's.
•Slot on the side of Carbon Brush indicates Limit for
Use. Change the Brush when it is abraded over the
Slot. To keep the good condition, we recommend to
change it earlier.
•Be careful so as not to tighten the Carbon Brush Cap
too strongly.
