Apply the brake up to full pressure.
4.
Check for leaks with brakes applied.
100 Hours Service - Check / Tighten Steering
If too much play is found in the steering section it must be re-tightened.
This applies to both steering and non-steering versions. Retighten the
nuts on both sides to the specified torque.

ATTENTION! Specified torque is 250 Nm.
Be sure that the split pin is fitted (or refitted if dismounted) at the end of
the big bolts.

Due to several movements of the spray boom from driving in the field with an unfolded boom, you must re-tighten all
bolted connections on the boom centre and boom wings.
Where you find bolts with Nord-Lock washers, please tighten with the
following torques.
