Adjustment
Any GARANT torque wrench must be
checked and readjusted regularly. We
DE
recommend this after approximately
every 5000 operations, but in any case at
the latest every twelve months.
Should no suitable tester with click point
recognition be available, then send your
GARANT torque wrench to the Hoffmann
Group, where it will be checked and
adjusted

Important notes
The following notes must be observed as
a matter of principle. This is the only way
to ensure problem-free use of this precisi-
on tool over longer periods of time.
After use we recommend to reset the
wrench to the lowest value (mainly if
there's a torque analyser in use).
GARANT torque wrenches are only inten-
ded for tightening screw connections.
Under no circumstances must they be
used as levers, clamping or hammering
tools!
Accessories
A comprehensive range of quality acces-
sories is available for all GARANT torque
wrenches.
