MAINTENANCE
Chapter 4 contains all the details which are needed for carrying out the necessary maintenance procedures. If faults
occur or a repair is needed which is not dealt with in this chapter, contact our engineer immediately.
4.1
Maintenance, Cleaning
For the proper and safe function of the product, regular cleaning and rotational maintenance is required.
When faults appear or a repair is needed, inform an authorised engineer. Before any cleaning work is carried out
the product must be switched off and separated from the mains power supply (pull out mains plug).
The product has hot surfaces.
Please let the product cool down before starting any cleaning work.
Clean the surfaces of the product with a dust free cloth. Take special care to keep the ventilation openings of the
crankcase chamber and the cylinder head free from dust and dirt.
4.2
Maintenance
The stated maintenance intervals are guidelines for normal working conditions. If there are extreme working conditions
(e.g. long work times under full load, high ambient temperature, very dusty atmosphere, high humidity) the maintenance
intervals will need to be shorter. When carrying out maintenance work, the product must be disconnected from the
power supply.
The product has hot surfaces.
Please let the product cool down before starting any cleaning work.
4.2.1 Drain condensate water from pressure tank
Mechanical condensate drainage:
Drain the condensate from the compressed air tank once a week.
Automatic condensate drainage:
Should the product be fitted with an automatic condensate drain valve, it will empty the compressed air tank on its
own at regular intervals.
For compressor types with drying installation the condensate will be separated automatically by the drying
installation.
