OM 0792
TORQUE WRENCH 1/2" 40-220Nm
3.1 - The initial state of the handle is 10 Nm.
3.2 - Pull the lock backwards to put the handle in the unlocked state. Do not release the the lock.
3.3 - To adjust the torque, simply turn the handle clockwise to increase the torque and anticlockwise
to decrease the torque. First turn the handle clockwise until you reach 60 Nm. The "0" on the
secondary scale must be aligned with the central mark on the main scale.
3.4 - Then turn the handle again to align the "6" on the secondary scale with the center mark on the
main scale. Release the lock. The handle is now locked with a torque value of 66 Nm.
3.5 - After use, if the key is not used for a long period of time, pull the lock backwards to unlock it.
backwards to unlock the key and return it to its initial state (10 Nm).
3.6 - The screw can be tightened with a fi xed torque by choosing an appropriate socket.
3.7 - During the tightening process, when the set torque is reached, the torque wrench emits a "click".
From this moment on, stop applying force immediately. This sound indicates that the torque
has reached the set value. During the tightening process, the torque must be applied evenly,
without applying any inertial force. When using a small torque, the "click" will not be evident.
An obvious slip will indicate that the torque has also reached the set torque value. (The "click"
sound of the small torque is not obvious because the spring is under a small compression).
1.1 - Before using the torque wrench, fi rst check that you have selected the correct torque wrench for the
tightening task.
1.2 - After selecting the appropriate torque wrench, check that the torque value corresponds to that expected.
1.3 - In order to guarantee the accuracy of the torque wrench, it is necessary to recalibrate it after one year
or 5000 uses.
1.4 - Please read the instructions carefully before using the torque wrench.
1.5 - If the torque wrench is not used for a long period of time, it is necessary to set torque wrench to the
minimum torque value, in order to avoid long-term compression of the spring. of the spring. This could
aff ect the accuracy of the torque wrench.
1.6 - Do not use the torque wrench to strike objects.
3 - Turn the handle to set the appropriate torque value, then release the lock.
(The fi gure below shows the method of setting to 66Nm).
