Setting the Torque

The tightening torque is dependent on the spring pre-

tension of the switch-off coupling. The switch-off

coupling responds in right as well as left rotation

when the torque setting is reached.

Type 0 602 491 647/... 650/... 651/... 652/... 656/

... 669/... 671/... 673/... 675

For setting the individual tightening torques, use only

the adjustment tool 27 provided.

Push the slide 7 on the power tool completely back.

Insert the Allen key 28 into the tool holder 1 and turn

slowly until a small indentation (adjustment disc 29

for the setting of the torque) is visible in the power tool

opening on the coupling. Insert the adjustment tool

27 into this indentation and turn it.

... 441/... 443/... 445

For setting the individual tightening torques, use only

the adjustment tool 27 provided.

Push the slide 7 on the power tool completely back.

Insert the adjustment tool 27 into the tool holder 2

and turn slowly until a small indentation (adjustment

disc 29 for the setting of the torque) is visible in the

power tool opening on the coupling. Insert the ad-

justment tool 27 into this indentation and turn it.

Turning in the clockwise direction results in a higher

torque, in the counterclockwise direction, a lower

torque.

Note: The required adjustment is dependent on the

type of threaded connection and can be best deter-

mined by practical trials. Check the trial screwings

with a torque wrench.

Marking the Torque Setting

Type 0 602 491 431/... 433/... 435/... 437/... 439/

To identify individually adjusted tightening torques,

the marking ring 19 can be replaced with a marking

ring of another color. Press off the marking ring 19

with a thin screwdriver blade, a knife, or similar.

Always use the power tool with a marking ring since

otherwise the housing is no longer closed.

English–13

Set the torque only in the specified per-

formance range, otherwise the shut-off

coupling will no longer respond.
