Tighten the nuts on the horizontal parallelogram link arms
The link arms act on the boom centre as a form of suspension. The link
arms have no adjustment however they are fitted with a high quality
ball end with a tapered shaft locked into each side of the boom centre.
It is important that the tapered shafts remain tight in their respective
housing.
The nuts should be done up at 160 Nm. It is recommended to check this
after the first days of operation and then at regular intervals of 250
hours.
Alignment of centre and lift frame
The centre is connected to the lift frame by an adjustable tie rod.
Adjust it as follows:
1. Unfold all boom sections
2. Loosen the locknut on the tie rod
3. Put a spirit level at the top or side of the centre, or measure if
centre is parallel to lift frame. Rotate the tie rod until the centre
is completely horizontal and aligned with the lift frame
4. Tighten the locknuts again
