Replacements and repairs

Safety is crucial in regard to all repair work on the drum. The following items
must therefore be observed at all times, as well as all items under safety at
the beginning of the instruction manual.

When replacing the cylinders, always fill the cylinder with oil before subject-
ing it to strain. It is therefore recommended that you mount the cylinder in
the fixed part of the frame first, after which the cylinder is filled with oil and
then mounted in the counterpart.
All maintenance and repair work on the drum must be conducted only when
the machine is lowered to the ground or is set in transport mode, the trac-
tor’s brake is on, the engine is switched off and the ignition key is removed,
so that the machine cannot move or start accidentally.
For all repair work on the hydraulics, always pay close attention to safety.
Before starting any work, release the pressure in the hydraulics system and,
if necessary, support the part.
Once the repair work on the hydraulics system is complete, the system must
always be vented before use to prevent mechanical breakdown and/or per-
sonal injury.
