instructions
Availability
You must always keep a complete and legible copy
of the operating instructions at the location at which
the torque and angle wrench is used.
If these operating instructions become lost or
unusable, a new copy can be requested from the
Hoffmann Group.
The generally applicable and local regulations
regarding accident prevention and environmental
protection must be made available and observed in
addition to these operating instructions.

Safety
Proper use
The TWdrive torque and angle wrench is used for
measuring torques and angles during the controlled
tightening and release of threaded connections in
the workshop area. To do this, an appropriate plug-
in tool must be connected to the torque and angle
wrench. A reference arm is not required when
measuring angles.
Never exceed the maximum limit torque of 125 % of
the nominal value.
Proper use additionally includes:
Compliance with all of the notices contained in
these operating instructions, particularly the safety
instructions
Observance of and compliance with the relevant
accident prevention regulations of the responsible
trade association and all other applicable safety
regulations .
Any other use is regarded as improper. The
Hoffmann Group accepts no liability for damage
arising as a result of this.
Improper operation particularly includes
The uncontrolled release of seized, e.g. rusted
tight, threaded connections
Use as a crowbar
Use as an impact tool.

Basic safety instructions
The torque and angle wrench is a precision tool and
must accordingly be handled with care. Avoid
mechanical, chemical or thermal influences which
exceed the stresses involved in proper use.
Make sure that extreme climatic conditions such as
cold, heat and humidity are unable to influence
accuracy.
Do not overload the torque wrench. Adhere to the
measuring range data on the model plate under all
circumstances. The torque and angle wrench may
otherwise be damaged.
Avoiding risks of injury
Do not use the torque and angle wrench as an
impact tool.
Check the torque and angle wrench and all
accessories for damage prior to use. Never use a
damaged torque and angle wrench or damaged
accessories.
Rechargeable batteries, batteries and small parts
such as e.g. bits must be kept out of the reach of
children. Children may put these into their mouths
and swallow them.
Never exceed the maximum limit torque of 125 %
of the nominal value. Observe the specifications
on the type plate.
Avoiding damage to the torque and angle wrench
Do not use the torque and angle wrench as an
impact tool.
Check the torque and angle wrench and all
accessories for damage prior to use. Never use a
damaged torque and angle wrench or damaged
accessories.
Do not overload the torque and angle wrench.
Excessive or permanent overloading may lead to
damage to the torque and angle wrench.
Never expose the torque and angle wrench to
rain, moisture or other fluids.
Do not allow any foreign bodies to enter the
torque and angle wrench housing. Always cover
the PC connection socket when not in use.
Do not use the torque and angle wrench for the
uncontrolled release of threaded connections
which are e.g. rusted tight.
Never exceed the maximum limit torque of 125 %
of the nominal value.
Never open the torque and angle wrench housing.
Make sure that all plug-in tools and connectors
which are used are firmly connected and correctly
inserted.
Leaking batteries and rechargeable batteries may
cause damage to the torque and angle wrench. If
the torque and angle wrench is not used for a long
time, remove the batteries.
Avoiding malfunctions
Check the device's accuracy at regular intervals,
see page 53.
Do not overload the torque and angle wrench.
Excessive or permanent overloading may lead to
torque and angle wrench measuring errors.
Never exceed the maximum limit torque of 125 %
of the nominal value.
