TEMPERATURE WARNINGS
When the torque wrench is exposed to
temperatures below 64°F and above 82°F, or high
levels of humidity (above 90%), it may cause
inaccurate torque settings.
ALWAYS check the torque wrench with an
approved torque tester before and during use in
these conditions.
The torque wrench is designed to tighten bolts and
nuts to a specific tightening or torque specification.
Take the following safety precautions to prevent
injuries and damage caused by improper handling
and unsafe use of the torque wrench:
NEVER use the torque wrench for loosening
bolts and nuts.
NEVER use a damaged torque wrench.
NEVER modify any parts of the torque
wrench or accessory parts.
NEVER use a torque wrench or an
accessory part that has been modified.
ALWAYS inspect the torque wrench,
especially the square drive and the
housing, for damage before use.
ALWAYS release the torque wrench
IMMEDIATELY after you hear the click
indicating that you have reached the
desired torque setting.
ALWAYS use the torque wrench ONLY in
the direction of rotation indicated on the
housing.
ALWAYS use only original accessory parts or
parts approved by the manufacturer.
ALWAYS reset the torque wrench to the
lowest setting after each use or at the end
of the workday.
ALWAYS hold the torque wrench in the
center of the handle when using the tool
accessories.
Setting the Torque
ALWAYS make sure that you use the scale with the
requisite unit. Non-compliance of the requisite scale
can result in faulty screw connections. These might
cause damage, SERIOUS INJURY or DEATH
Familiarize yourself with the torque wrench and its
scales. The torque wrenches are equipped with a
double scale (N∙m / lbf∙ft or lbf∙in). Check the unit
and scale required.
The desired torque ALWAYS has to be set before
using the torque wrench.
Pull out the locking button (1) on
the end of the handle (2).
Turn the handle (2) until the desired
torque in the particular scale(3) N·m
or lbf·ft / lbf·in is identical with the
mark in the reading glass.
Make a precise adjustment of the
main scale using the micrometer
scale (4).
Push the locking button (1) back into
the end of the handle (2). Attention
should be paid to ensure that the
locking button(1) engages properly.
Only then is the torque safe.
To change the direction of rotation for the ¾“
with square drive, push the trigger pin with your
thumb and push the square drive through,
rotate the torque wrench and replace the
square drive.
Operation:
Using a suitable socket, turn the torque wrench by
the handle slowly and steadily in the direction of the
arrow (follow the direction of rotation arrow) until a
click sound can be heard and a slight jerk felt.
ALWAYS release the torque wrench
IMMEDIATELY on the sound of a click. After use,
ALWAYS reset the torque wrench to the lowest
setting.

Maintenance
Testing and Calibrating
FAULTY TIGHTENING TORQUE HAZARD
An un-calibrated torque wrench can cause
screw connections, the torque wrench and
accessories to fail and produce faulty screw
connections. This might cause SERIOUS INJURY
or DEATH.
Always use tested and calibrated torque
wrenches ONLY. Always use tested torque
testing equipment ONLY.
Powerful forces are at work when using the
torque wrench. When torque wrenches are not
tested or not serviced there is a risk that they
will not bear the loads or will indicate faulty
tightening torques. ALWAYS take the following
safety information into account in order to
prevent SERIOUS INJURY or DEATH:
ALWAYS test the accuracy of the torque
wrench with an approved torque tester
before use.
NEVER use a faulty torque wrench.
ALWAYS have the torque wrench
calibrated on a regular basis.
According to DIN EN ISO 6789 the minimum
calibration interval requirement for a torque wrench
is one year or 5000 load cycles (whichever case
occurs first). A firm’s own specifications or quality
requirements for screwing applications can also
lead to considerably shorter calibration intervals.
WARNING
NEVER neglect recalibrating the torque wrench.
Improper calibration can cause the torque wrench
to be damaged.
Calibration should ONLY be implemented by
authorized specialists, 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.
