4. operAtioN
Please refer to the maker’s instructions for correct use and setting of the torque wrench.
4.1.
The AK6290 is used in combination with a suitable drive tool, such as a ratchet wrench or torque wrench fitted into the female input
socket and a suitable size socket fitted onto the male 3/4” drive square (fig.1).
4.2.
If using a torque wrench calculate the required input figure for the torque wrench by dividing the torque setting for the fixing by a factor
of 6.5.
4.3.
The torque multiplier can either be used with the long or the 90° reaction bar. The 90° Reaction bar can be adjusted to use with
a normal or a deep socket (see fig.1).
4.4.
This assembly (fig.1) is now placed on the nut or bolt to be tightened with the Reaction bar if possible restrained against some
substantial part of the equipment being serviced. Any force applied to the input drive is multiplied by a factor of 6.5 at the output drive of
the multiplier.
Note:
Because the multiplier uses a system of gears, the output drive turns substantially slower than the input drive. When the preset
torque setting is reached, the torque wrench mechanism will “click.” Stop applying force immediately to avoid overtightening the
nut/bolt.
