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)
