Hints
Use the torque table at the end of these instructions The standard unit of measurement is the Newton-metre, symbol Nm
1 metre-kilo = 9.81 Nm
(about 10 Nm)
1 ft/lb = 1.35 Nm 1 in/lb = 0,1128 Nm 1 in/oz = 0.00705 Nm
1 Nm = 0.102 metre-kilo
(about 100 g/m)
1Nm = 0,738 ft/lb 1 Nm = 8.863 in/lb 1 Nm = 141.8 in/oz
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 :
For series 208 . 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 stan-
dard. A dated and numbered official document is drawn up.
For further information ; ask your dealer.
For series 248. Test report : Repetitive 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.
Pre-setting : Setting to required torque and testing repeatability.
A dated and numbered report is 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 Unscrew plug b and insert an allen key at the
back of the wrench.
2 Adjust to the required torque with a testing
device. Tighen to increase the torque, untighten
to decrease.
3 Remove the allen hey and screw plug b back on.
