use,

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

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

and

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 a ect the accuracy

of the torque wrench.

1.6 - Do not use the torque wrench to strike

objects.
