Important Note*: Only torque wrenches with
aluminum alloy housing are available with a
double square drive.
Throughout these Operating Instructions, the
procedures are described, and depicted
graphically for a torque wrench with a single
square drive. Please note that the procedures
are the same for torque wrenches with a double
square drive
Setting the Torque
ALWAYS make sure that you set the torque
wrench in the appropriate scale. Failure to use
the appropriate scale can result in incorrectly
torque loaded bolts causing DAMAGE.
The TWM1000 torque wrench is equipped with
a double scale (Nm / lbfft or lbfin). Check
the unit and scale. Familiarize yourself with the
torque wrench and its scales.
If using nonstandard extensions end fittings, the
torque wrench setting must be adjusted. Non-
standard extension end fittings increase the
effective length of the wrench. As a result, the
actual torque applied to the bolt you are
tightening will be higher than the setting on the
torque wrench.
ALWAYS set the desired torque before using the
torque wrench. The procedures for setting the
torque are different depending on type of
torque wrench you are using:
Aluminium alloy housing:
Pull out the Hexagon-Key (A) on the end of the
handle (B) and angle it up
Turn the Hexagon-Key (A) until the desired
torque in the particular scale (C) Nm or lbfft
corresponds with the mark on the housing.
(If using extension pieces, see section 3.4.)
Bring the Hexagon-Key (A) back into the
starting position and push it into the end of the
handle (B).
Working with Non-standard Extension End
Fittings
NEVER use non-standard extension end fittings
with a torque wrench with a built-in ratchet or
ratchet adaptor.
You must read and understand these
instructions before using non-standard
extension end fittings with the torque wrench.
Bolts incorrectly torque loaded can cause
DAMAGE and SERIOUS INJURY.
Non-standard extension end fittings increase
the effective length of the wrench. As a result,
the actual torque applied to the bolt you are
tightening will be higher than the setting on the
torque wrench.
The new setting for the torque wrench (MxW)
must be calculated according to the following
formula:
MxW = Torque Wrench Setting: the torque
that has to be set on the torque
wrench scale.
MA= Desired Torque Setting: the torque
that the bolt or nut needs to be
tightened to.
Lw = Torque Wrench Length: the
distance between the center of the
torque wrench’s square drive and
the center of the handle (see table
in section 7).
Lx= Extension Length: the distance
between the center of the torque wrench’s
square drive and the center of the bolt or nut
(also called depth gauge of the end fitting

Safety Precautions
Take the following safety precautions to
prevent injuries and damage when using the
torque wrench:
ALWAYS use only original accessory
parts or parts approved by the
manufacturer.
ALWAYS check the torque wrench for
the proper torque setting prior to
tightening every bolt.
ALWAYS position the torque wrench
and socket extensions at a 90° angle.
Use ratchet adapters when working in
tight work areas. Reverse the torque
wrench without removing it.

Maintenance
Checking and Calibrating
An out-of-calibration torque wrench can cause
part or tool breakage and inaccurate torque
settings.
ALWAYS use tested and calibrated torque
wrenches only. ALWAYS use an approved
torque tester.
During use, the torque wrench creates very
powerful forces. When torque wrenches are
not checked or not serviced there is a risk that
they will overload or indicate inaccurate
torque settings.
ALWAYS take the following safety precautions.
ALWAYS check the accuracy of the
torque wrench with an approved
torque tester before each use.
DO NOT use the torque wrench if
inaccurate.
ALWAYS have your torque wrench
periodically recalibrated.
According to DIN EN ISO 6789, the minimum
calibration interval requirement for a torque
wrench is one year or 5000 load cycles
(whichever occurs first). A firm’s own
specifications or quality requirements for
specific applications can lead to considerably
shorter calibration intervals.
DO NOT attempt to recalibrate your torque
wrench. Improper calibration can cause
damage to your torque wrench.
Calibration should be conducted by
authorized personnel ONLY, such as an
accredited calibration laboratory or the
manufacturer.
A calibration certificate as per DIN EN ISO 6789
comes with every new torque wrench. The
torque wrench and the calibration certificate
are labeled with the identical serial number.
