in
the wrench body tube. Turn the square drive as shown in figure
1 to clamp on the right and turn through 180
°
to clamp on the
left.
2
. Locate the threaded axis to secure the wrench end assembly.
3
. Preset the needle of the wrench to the torque graduation desired
using the adjustment screw on the side.
Tightening
A
- Place your wrench at right angles to the tightening axis.
B
- Centre the force on the notch of the handle.
C
- Gradually pull in the direction of the arrow on the casing, perpen-
dicular to the wrench, until the point to moves towards zero.
D
- When you see the indicator light come on and hear the beep,
stop immediately.
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.
1 ft/lb = 1,35 Nm.
1 in/lb = 0,1128 Nm.
1 in/oz = 0,00705 Nm.
1 Nm = 0,102 metre-kilo.
1 Nm = 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.
• A screw that is tightened to an excessive torque load may shear. Forces produced in obtaining high torque levels must be controlled at all
times.
• A torque wrench is a measurement instrument and must be tested if ever it is allowed to fall.
Maintenance
• Clean your torque wrench with a dry cloth. Never use solvent or detergent.
• To replace the 9 Volt battery
(6LR61 or PP3)
, remove the cover from the casing
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 every two
years, or more often for intensive use or it it is dropped)
.
Precision checking and updating of reports
• The FACOM metrological laboratory will draw up checking reports or calibration reports on request :
Checking 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 report :
Testing and adjustment or the torque wrench at 6 to 12 values, testing apparaturs linked to the national measuring
standard. A dated and numbered official document is drawn up.
For further information, ask your dealer.
