Introduction to the operating
instructions
These operating instructions help you to use the
electronic torque wrench 701 properly, safely and
economically. The electronic torque wrench 701 will
be referred to as torque wrench in the following.
These instructions are aimed at the operators of the
torque wrench. We assume that these users
possess general technical knowledge. In
particularly, these instructions are aimed at
customer service installation engineers, trained
specialist personnel and qualified and authorised
operating personnel.
Each person who undertakes the following activities
with and on the torque wrench must have read and
understood the contents of these instructions:
Transportation
Usage
Cleaning
Maintenance or
Disposal.
Compliance with these instructions helps to avoid
dangers and to increase the reliability and service
life of the torque wrench. In addition to the notes
contained in these instructions, also always observe
the legal and other regulations applicable at the
installation location, such as e.g.:
Accident prevention regulations
Regulations for safe and proper work.
Regulations on environmental protection.
Supplements
Regularly supplement the operating instructions at
the relevant point of use with instructions based on
Legal regulations concerning accident prevention,
Legal regulations concerning environmental
protection and
Trade association stipulations.
Availability
These operating instructions form part of the torque
wrench. You must always keep a complete and
legible copy of the instructions at the location at
which the torque wrench is used. Make sure that
the instructions are available to the user. Enclose
these instructions if you sell the torque wrench or
pass it on in any other manner.
These operating instructions can also be
downloaded from the "www.stahlwille.de" website.

Safety
Proper use, operating area
The electronic torque wrench 701 is used for
measuring torque values during the controlled
tightening and release of threaded connections in
the workshop area. To do this, an appropriate
socket must be connected to the torque wrench.
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.
EDUARD WILLE GMBH & CO. KG accepts no
liability for damage arising as a result of this.
Basic safety instructions
The torque 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 wrench may otherwise
be damaged.
Avoiding risks of injury
Do not use the torque wrench as an impact tool.
Check the torque wrench and all accessories for
damage prior to use. Never use a damaged
torque wrench or damaged accessories.
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 expose the torque wrench to rain, moisture
or other fluids. Ingressing fluids can cause
incorrect measured values and therefore unsafe
threaded connections.
Do not use the torque wrench in aggressive
atmospheres. An ingressing aggressive
atmosphere can cause incorrect measured values
and therefore unsafe threaded connections.

Safety

Never exceed the maximum limit torque of 125 %
of the nominal value. Observe the specifications
on the type plate.
Avoiding damage to the torque wrench
Do not use the torque wrench as an impact tool.
Check the torque wrench and all accessories for
damage prior to use. Never use a damaged
torque wrench or damaged accessories.
Do not overload the torque wrench. Excessive or
permanent overloading may lead to damage to
the torque wrench.
Never expose the torque wrench to rain, moisture
or other fluids. Ingressing fluids can cause
incorrect measured values and therefore unsafe
threaded connections.
Do not use the torque wrench in aggressive
atmospheres. An ingressing aggressive
atmosphere can cause incorrect measured values
and therefore unsafe threaded connections.
Do not allow any foreign bodies to enter the
torque wrench housing. Always cover the PC
connection socket when not in use.
Do not use the torque 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 wrench housing.
Make sure that all inserts and connectors which
are used are firmly connected and correctly
inserted.
Leaking batteries can cause damage to the torque
wrench. If the torque wrench is not used for a long
time, remove the battery.
Avoiding malfunctions
Check the device's accuracy at regular intervals,
see page 24.
Do not overload the torque wrench. Excessive or
permanent overloading may lead to torque
wrench measuring errors.
Never exceed the maximum limit torque of 125 %
of the nominal value.
Do not kink the cables and connectors, and never
expose these to excessive tensile forces or
temperatures.
Make sure that all inserts and connectors which
are used are firmly connected and correctly
inserted.
Environmental pollution due to incorrect disposal
Dispose of cleaning agents and lubricants
according to the regulations applicable at the
operating location.
Dispose of the torque wrench according to the
regulations applicable at the operating location.

Safety

Handling batteries
Batteries may contain poisonous substances
which pollute the environment.
Batteries must be kept out of the reach of
children. Children may put these into their mouths
and swallow them.
Leaking batteries can cause damage to the torque
wrench. If the torque wrench is not used for a long
time, remove the battery. If a battery has leaked,
put on protective gloves and clean the battery
compartment with a dry cloth.
Exchange a weakening battery in good time.
Do not charge batteries.
Always dispose of batteries according to the
applicable legal regulations.
Only use batteries which correspond to the data in
the chapter entitled "Technical data".

listed in the STAHLWILLE catalogue.
CAUTION
Risk of injury due to exceeding the
maximum load-bearing capability of
the sockets.
Make sure that you do not exceed
the maximum load-bearing capability
of the sockets.
The maximum load-bearing capability of the sockets
may be lower than the maximum permissible torque
of the torque wrench.
ATTENTION
Damage to the measuring elements of
the torque wrench possible.
Protect the torque wrench e.g.
against hard jolts or dropping.
Make sure that the sockets are the correct profile
and size for connection with the threaded
connection to be tightened.
WARNING
Risk of injury due to unintentional
movement of the ratchet switching
lever.
Prior to the bolting process, use the
switching lever to set the desired
working direction.
Do not touch the switching lever
during the process.
Use the switching lever to set the desired working
direction.
CAUTION
Risk of injury due to incorrectly
mounted sockets.
