Disassembly And Disposal - Mandam TOP 2.5 Operation Manual

Replacement of working components
Excessively worn working components make it difficult for the tools to sink in,
increase working resistance and insufficiently mix harvest residues. The working
components must be changed on the machine lowered to the ground after the tractor
engine has been switched off. To ensure that the components to be replaced do not rest
on the ground, sturdy shims should be placed under the shaft. After lowering the
cultivator, switching off the engine and applying the handbrake, check the stability of the
tractor-machine unit. Only typical screws should be used to fix new components.
If machine components are disassembled several times, it is necessary to inspect and
possibly replace connecting elements such as bolts, washers or nuts, excessive wear
of which may lead to uncontrolled loosening of the connecting elements and
subsequent damage.
When working on extremely worn work tools, such work can cause, for example,
bearing damage in the case of a small disc diameter. Tools should be replaced when
their wear and tear exceeds the limits allowed by the manual. If the recommendations
are not followed, damage may occur for which the manufacturer is NOT RESPONSIBLE!
Replacement of cylinders
A malfunctioning cylinder, leakage, etc. should be dismantled and taken to a
specialist workshop. Replacement of the cylinder must be carried out on an unfolded
machine. Connect the cylinder to the system and, when mounted on one side, run through
the entire cycle a couple of times to fill the cylinder completely with oil.
Failure to do so may result in a sudden fall of the drop section.
The bearings of the levelling discs are not demountable. If damaged, they should be
replaced in their entirety.
NOTE! When carrying out repairs and maintenance, the machine should be
lowered to the ground and supported on supports to ensure full stability and
the tractor engine switched off. Use proper spanners and protective gloves
during maintenance and repairs.

7. Disassembly and disposal

A machine used in accordance with the instructions in this manual will last for many
years, but worn or damaged parts must be replaced. In the event of emergency damage
(cracks or deformation of the frames) impairing the quality of the machine and posing a
danger to further operation, the machine must be disposed of.
The disassembly of the machine should be carried out by persons previously gotten familiar
with its construction. These operations should be carried out after the machine has been
set up on a level and stable surface. Sequence of activities:
• Disconnect the shaft bracket from the arms. Remove the bearing mounting bolts
and roll the shaft to one side.
• Disconnect the shaft arms from the frame.
• Remove the three-point hitch turret arms connecting to the main frame (for non-
welded three-point hitch).
• Remove the three-point hitch turret.
• Place the frame on stable stands. For units with folding side arms, additional stands
must be prepared.
• Remove the working components of the unit.
