3. Cable: remove the pins
4. Cable: Pull the cable out of the gravity weight

5. Shorten the cable/rod with a cut-off wheel or metal saw at the

marking. Take note of the specifications in the following illustration

when shortening the cable.

6. Cable with gravity weight: Shift the cable according to the drawing

into the gravity weight

7. Cable with gravity weight: Fasten cable with the pins, torque 7 Nm

(5.16 lbf ft)
Cable with centering weight: Fasten cable with the pins, torque

7 Nm (5.16 lbf ft) and fix the clamping part on the centering

weight.

8. Enter new probe length and then carry out a fresh adjustment

(see "

Setup procedure, Carrying out min. adjustment - Carrying

out max. adjustment

").
