Technical description

All models

Manoskop

721, 730 are adjustable

torque wrenches with a cut-out, tactile
and audible cut-out signals.

•

These torque wrenches have a safety
cut-out mechanism.

•

The wrench is set to cut-out at a
certain torque level by setting the
required value on the force-free
sliding scale.

•

The setting slide has an automatic
setting fail-safe mechanism.

•

The measuring element is a flexible
rod. The flexible rod is not
pretensioned so it is only under
tension from the start to the end of the
actual tightening operation until the
wrench cuts out.
