Manutention de pièces mécaniques
6.5. Maintenance of mechanical parts
Carry out the dismantling and movement of heavy
components (over 30Kg) with the help of block and
tackles or cranes.
If detailed diagrams are not available take note of
every item and mark its location so as to avoid errors
in reassembling.
Always use spanners of the correct size.
Immediately replace screws or bolts which show
signs of wear on the threads and the heads.
When screwing and unscrewing do not use the
spanners in conjunction with extensions to augment
the torque.
If dynamometric spanners and special tools are
used verify that the calibration is appropriate for the
component.
Special care must be taken when using pneumatic
or hydraulic tools.
Before dismantling heavily oxidised parts spray them
with adequate liquids (Svitol, etc.)
Before reassembling cover thinly with oil all the
coupled surfaces.
During reassembly pay particular attention to anti-
slip devices used by the manufacturer (flat washers,
elastic washers, etc.), always replacing the worn out
elements.
The anti-slip nuts and ring nuts having a plastic
blocking ring must be replaced at every reassembly
since the fatigued material will lose its functionality.
Attention
Always use personal protection equipment such
as gloves, anti-injury shoes, etc. Unscrew the
four knobs (11) to wash the two guides
6.6. Maintenance of electrical parts
Before taking any action on electrical components
disconnect the mains-side supply (main power
switch).
Always carefully check the isolating covers, the
clamps and the grip of the sheaths.
This must always conform to the level of protection
stated by the manufacturer.
Immediately replace the damaged gaskets and
sheaths.
Check and restore, if necessary, the identification
labels and stickers of the wires and of the
components keeping to the indications shown in the
diagrams.
Make sure that the hazard indications and
explanatory plaques required by the norms are
perfectly legible and firmly fixed.
Do not use compressed air for cleaning. Use only
vacuum machines.
The replacement of faulty control components must
always be carried out according to the norms
(colours, dimensions, protections, etc).
