2
• Turn the handle and set the vernier to the desired graduation
3
• Release the ring, which will then click
Hints
• The standard unit of measurement is the Newton-metre, symbol "Nm"
1 metre-kilo = 9.81 Nm (about 10 Nm)
1 Nm = 0.102 metre-kilo (about 100 g/m)
•
Never exceed the maximum torque of your wrench, taking special care when freeing tight nuts and during angular tightening.
•
Set the torque wrench to the minimum torque before putting it away in its box.
Maintenance
•
Clean your torque wrench with a dry cloth. Do not use any solvent or detergent.
•
Never dismantle.
Maintenance of precision
•
We advise you to have your torque wrench checked regularly on a test rig or by the FACOM metrological laboratory (about once a year, or more often
for intensive use or if dropped) .
Precision checking and updating of reports:
•
The FACOM metrological laboratory will draw up test reports or calibration certificates on request :
Test report : Testing and adjustment, if necessary, at 20, 60 and 100% of the torque wrench's capacity, within the tolerances specified in the standard.
A dated and numbered report is drawn up.
Calibration certificate : Testing and adjustment of the torque wrench at 6 or 12 values, testing apparatus linked to the national measuring standard.
A dated and numbered official document is

into position.
1 ft/lb = 1.35 Nm
1Nm = 0,738 ft/lb
drawn up.
Tightening
A
• Hold the torque wrench at right angles to the tightening axis
B
• Place your hand in the middle of the handle
C
• Pull progressively and at right angles to the torque wrench
D
• When the wrench "clicks" stop pulling immediately.
1 in/lb = 0,1128 Nm
1 Nm = 8.863 in/lb
1 in/oz = 0.00705 Nm
1 Nm = 141.8 in/oz
