For series 208
1 • Pull the ring towards the handle
2 • Turn the handle and set the vernier to
the desired graduation
3
• Release the ring, which will then click
into position.
Hints
• Use the torque table at the end of these instructions
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
.
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.
Setting the required torque
1 • Unscrew plug
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
• The standard unit of measurement is the Newton-metre, symbol "Nm"
1 ft/lb = 1.35 Nm
1Nm = 0,738 ft/lb
For series 248
b and insert an allen key at the
b back on.
1 in/lb = 0,1128 Nm
1 Nm = 8.863 in/lb
For series 248. Test report : Repetitive testing
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 in/oz = 0.00705 Nm
1 Nm = 141.8 in/oz
(about once a year, or more often for intensive
