TORQUE MULTIPLIERS with anti-wind up system
If the anti-wind up system cannot be released, start it again, by pushing the selector in the
counterclockwise direction. Replace the wrench and follow procedure 3 until the anti-wind
up mechanism is released completely. Test the direction of rotation, and make sure that
the system can run freely.
4. The tool can be removed from the fastening device.
5. Get used to this item by initially applying low torques and the anti-wind up system.
NB: The gears and teeth of the anti-wind up system should be checked for wear or
damage every year.
MAINTENANCE
Replacing the output square drives is the only maintenance job the user is expected to carry
out on torque multipliers. To avoid internal damage (especially due to torque overload), the
output square drive and the shaft have been designed to shear first. This saves internal da-
mage and allows easy removal.
Sometimes the output square drive cannot be removed without taking the gear cover apart.
Therefore, the torque multiplier should be taken to an authorized Beta dealer, who will send it
to our headquarters for replacement.
The square drive can often be replaced without taking the gear cover apart. When this is the
case, remove the bolt (M4 or M5) that holds the square drive in position. Then remove the
broken or damaged square drive and fit in the new square drive. Tighten the bolt (4.7 Nm for
M4 bolts, and 9 Nm for M5 bolts).
