fig.6
In order to keep the compressor in good working condition, periodic maintenance is
essential.
IMPORTANT! Failure to carry out maintenance tasks may invalidate the warranty on
your compressor.
 WARNING! Before performing any maintenance operation, switch off the compressor,
disconnect from electricity supply and release all air from the tank. (Except for 6.3.a)
6.1. OPERATIONS TO BE CARRIED OUT AFTER THE FIRST 50 WORKING HOURS:
a) Check that all bolts/nuts are tight, particularly those retaining the crankcase and
cylinder head.
b) Replace the lubricating oil - see para 6.5.
6.2. OPERATIONS TO BE CARRIED OUT WEEKLY:
a) Drain condensation by opening the drain cock located under the tank (fig.3). Place a
container under the valve and open the valve by turning anticlockwise.
 WARNING! Take care if there is compressed air in the tank as water could flow out with
considerable force. Recommended pressure 1 - 2bar max.
b) Check oil level and if necessary, top up.
6.3. OPERATIONS TO BE CARRIED OUT EVERY 50 HOURS:
(or more frequently, if the compressor operates in a very dusty atmosphere):
a) Turn off the compressor and remove the filter element (fig.4). Using stored air from its
tank, clean the filter with compressed air. (Wear eye protection and DO NOT direct
air towards the body or hands). DO NOT operate the compressor without the filter as
foreign bodies or dust could seriously damage the pump. Replace the filter element.
b) Check for oil leaks.
6.4. OPERATIONS TO BE CARRIED OUT EVERY 100 HOURS:
a) Check the automatic cut-out at max. pressure and the automatic cut-in at 2bar below.
6. MAINTENANCE
6.5. OPERATIONS TO BE CARRIED OUT EVERY 400 HOURS:
a) Replace the lubricating oil. For oil specifications see 6.6. Remove the dipstick/breather
plug then unscrew oil drain plug (fig.1/fig.5), draining the oil into a container. Drain when
the compressor is hot so that oil drains rapidly and completely.
Replace oil drain plug and refill through the dipstick/breather aperture. Do not overfill.
Replace dipstick.
b) Replace air filter.
c) Check all tube fittings and electrical connections.
d) Inspect pressure tank inside and out for damage or corrosion.
 WARNING! Never mix different oils and do not use non-detergent/low quality oils as
the compressor may be damaged.
 WARNING! Dispose of waste oil only in accordance with local authority requirements.
6.6. RECOMMENDED OILS
Synthetic oil suitable for temperatures ranging from -5°C to 45°C, viscosity 5W50.
We do not recommend using mineral oil in these compressors.
