Replacements and repairs
Safety is crucial in regard to all repair work on the TRIMAX. The following
items must therefore be observed at all times, as well as all items under safety
at the beginning of the instruction manual.
All maintenance and repair work on TRIMAX must be conducted only when
the machine is lowered to the ground or, is set in transport mode, the tractor
has the break 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 the work is started, release the pressure from the hydraulics system.
When replacing the cylinders, always fill the cylinder with oil before
subjecting 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.
Once the repair work on the hydraulics system is complete, the system must
always be vented before use to prevent mechanical breakdown and/or personal
injury.

1.
The pressure is removed from the
cylinders. The hoses are removed.
2.
Cotter pins and nails are removed,
and then the cylinder is free.
3.
The new or repaired cylinder is
installed. Remember to secure the
nail in the nail stop and secure the
nails with cotter pins.
4.
The hoses are installed. After
installation, ensure that there is no
risk of tearing or clamping the
hoses.
After mounting, the cylinders are activated for unfolding and folding until a
small amount of movement can be felt in the cylinders. The cylinders are then
activated in the opposite direction until the cylinders are back in the starting
position. The cylinders are moved in this way a few times.
No individuals should ever be present within the tool’s activity radius.
