SELECTION GUIDE
FONCTIONNEMENT
Before using this torque wrench, please read these
instructions carefully. If you have any questions,
please contact the CLAS service department to
avoid safety accidents and damage to the tool
caused by improper use.
Select the appropriate torque wrench and socket
based on the torque value required by the bolt
or nut to be required by the bolt or nut to be
tightened.

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).
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).
PRECAUTIONS OF USE
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.
