How to Use
• Set the torque value.
Set the torque value on the graduation of the torque wrench.
The value on the graduation is multiplied value by the gear ratio. Therefore, the torque value
on the graduation should be the same as the value you wish to apply on the bolt.
You do not need to multiply the torque value by the gear ratio of the main body.
1. Loosen the locker.
2. Rotate the sub graduation and set the torque value (main grad sub graduation).
3. Lock the locker (clockwise).
(If the locker is hindered by the pin, relocate the pin to the appropriate position.)

• Set TW750N2/1000N2 main body to the bolt and the nut.
To set the position of TW750N2/1000N2 main body, vertical position (height) can be adjusted
by the gas damper and horizontal position by sliding the shaft.
Example) Set torque value to 550N·m.
1. See the main graduation while
rotating the sub graduation. When
it comes close to 500N·m on the
main graduation, check the value
on the sub graduation. Align 0 of
the sub graduation to the red dot.
Now, the torque wrench is set to
500N·m.
2. See the sub graduation and rotate
it clockwise until 50 is aligned to
the red dot. Now, the torque
wrench is set to 550N·m.
