and it free both hands to operate tool.
4. Guard Against Electric Shock.
Prevent body contact with grounded surfaces, for example:
pipes, radiators, ranges, refrigerator enclosures.
5. Keep Children Away.
Do not let visitors contact tool. All visitors should be kept away
from work area.
6. Store Idle Tools.
When not in use, tools should be stored in dry, and high or
locked-up place out of reach of children.
7. Don't Force Tool.
It will do the job better and safer at the rate for which it was
intended.
8. Remove Adjusting Keys And Wrenches.
From habit of checking to see that keys and adjusting
wrenches are removed from tool before turning it on.
9. Use Right Tool.

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 tightening
torque.
3. Make sure the Forward/O/Reverse Switch is in the "OFF"
position.
4. Insert the AC Plug into the AC socket.
5. Set the Forward/O/Reverse Switch at the "FORWARD"
position.
(Caution)
Whenever the direction of rotation is changed, make sure the
Forward/O/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 xed value.
Release the Switch Lever to put the Bit o 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/O/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 forenger.
Drivers of this type are identied 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 specically cautioned to disconnect the
cord to shut o power when handling the Quick Change Collet
for replacing bit to avoid danger from surprising starting.

- 12 -
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 rmly locked
after it has been attached.
• The VZ-1812, VZ-1820, VZ-3007
and VZ-3012 series has a chuck
to suit both the HIOS shank H5
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 dierence between xed 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 adjustment, nd
the most suitable point.
• The VZ-1510 (VZ-1510PS) Electric Screwdriver have ‘Double
nut system’ (Nut xing 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 rst, stop the Nut xing ring upper
surface to t the graduation, if you
want to adjust.
(2) Then turn the Torque adjusting nut so
as to push up the Nut xing ring.
(3) Lastly, to avoid the loosening of the
Torque adjusting nut strongly fasten
the Nut xing 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)

■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 (concavity). Insert the Brush to t 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.
