As soon as the torque wrench has cut out, 
it is ready for the next job.

Maintenance

The internal mechanisms of the torque 
wrench are subject to normal wear and 
tear under operating conditions. For this 
reason, the accuracy of the cut-out should 
be checked at regular intervals. 
Unless otherwise indicated in the user's 
internal regulations (e.g. test equipment 
inspection to ISO 9000 et seq), an 
inspection must take place after approx. 
5000 operations or every 12 months, 
whichever is the shorter. The time frame 
(12 months) starts with the first usage.
If inspection shows that there is a 
deviation, the torque wrench must be 
adjusted.
The inspection and adjustment must be 
carried out in accordance with 
DIN EN ISO 6789.

ã

CAUTION !

Important! Once the 
wrench has cut out, 
never apply more 
pressure! You should 
therefore not pull too 
fast in case you cannot 
stop the motion quickly 
enough when you hear 
the click.
