In order to reverse the operation of this spanner move the cam lever from its middle position either to the left or to the right to obtain the function required. In the middle position the ratchet function is eliminated and the spanner can be used in both directions as an ordinary spanner.

The same functions can be set on the model with the knurled sleeve by turning the knurled sleeve by 90^o either to the right or to the left. In the centre position the ratchet position is eliminated and it will operate as an ordinary spanner.

To exchange the inserts remove screw and cover.
