Storage
When the motor-compressor is out of action, there are some mechanisms which might rust (particularly
in very damp climates), and cause difficulties and malfunctioning when the machine starts up. For this reason, it
is advisable to take some precautions during the storage periods. Below we provide a brief summary of these.
If the period is going to be a short one (one or two months) it should be sufficient to start up the unit
once a week, so that it functions on load so that it circulates a good amount of oil through the circuit, until it
heats up and then keep it like that for 15 minutes. During this period the outlet tap will open and close so that
the regulation mechanism moves, thus avoiding subsequent strangulation.
When the storage time is to be longer the protective operations need to be longer:
•
Empty the compressor oil circuit when the unit is still warm and refill it with protective oil
•
Check and clean properly the motor aspiration and compressor filters.
•
The oil filters and the separator can be left if they are in good condition. If the loss of load
approaches limit values, then change them
•
Empty and clean the fuel tank. Then mix the fuel with the protective oil (10%) and refill it
•
Bleed the fuel system.
•
Start the equipment and run it on load for 10 minutes to ensure that the protective device
reaches all the elements.
•
Close the valves or outlet taps.
•
Dismantle the batteries, check that the level of the vessels is correct and store them for in the
place set aside for this purpose.
•
Remove the belts and grease the protective elements of the pulleys.
•
Now empty the compressor oil system.
•
Protect the terminals of the electrical circuit with the appropriate elements.
•
Grease all the articulations, wheel hubs, brakes and mechanisms.
•
Clean the unit removing foreign elements and cover the motor and compressor openings with
water resistant material.
•
Bear in mind the storage of the motor (section 12.1).
•
Close the chassis, clean the external surface and apply a layer of protective wax.
•
Note in a visible place that prior to starting the machine up again, it is necessary to check and
fill the oil circuit.
•
Check that the place where the machine is kept is appropriate and protected from the elements
•
Block or stabilize the unit prior to storing it.
These are minimum precautions, to be taken in normal environmental conditions. However, periodical
inspections are advisable and if there is any sign of rust anywhere immediately take the appropriate measures.

Conservation of motors and compressors
Below we explain how to deal with motor compressors activated by diesel motor when it is not planned
to use them for periods between 6 and 12 months.
This procedure is valid for new compressors, that is, those which manufacturing takes into account that
their start up will be delayed, for example, those machines for export, or also for those which though they have
been working for some time, their proprietor does not expect to use them for a season (campaign work, winter
stoppages, etc.).
The description below is both for the motor and the compressor. However, in the “User Manuals”
delivered with the motors the manufacturer explains the procedure.
