MAINTENANCE
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 5.3.a)
5.1.
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 5.5.a.
5.2.
OPERATIONS TO BE CARRIED OUT WEEKLY:
a)
Drain condensation by opening the valve located under the
tank (fig.9). Place a container under the valve and open the
valve by turning anti-clockwise.
WARNING! Take care if there is still pressure inside the cylinder
as water could flow out with coinsiderable force.
Recommended pressure 1 - 2bar max.
b)
Check oil level and, if necessary, top up.
5.3.
OPERATIONS TO BE CARRIED OUT EVERY 50 HOURS:
(or more frequently, if the compressor operates in a very
dusty atmosphere):
a)
Remove the air filter element (fig.7). Using stored air from
the compressor's 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 and air filter housing.
b)
Check for oil leaks.
5.4.
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.
5.5.
OPERATIONS TO BE CARRIED OUT EVERY 400 HOURS:
a)
Replace the lubricating oil. For oil specifications see 5.7.
Remove the filler/breather plug, then remove the oil drainer
plug (fig.4), draining the oil into a container. Drain
when the compressor is hot so that the oil drains rapidly and
completely. Replace oil drain plug and refill through the filler/
breather aperture. Do not overfill. Replace filler/breather
plug.
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.
b)
Replace air filter. (fig.7)
c)
Check all tube fittings and electrical connections.
d)
Inspect pressure tank inside and out for damage or corrosion.

IMPORTANT WARNING - Air contaminants taken into the
compressor will affect optimum performance. Example: Body filler
dust or paint overspray will clog the pump intake filter and may
cause internal damage to pump/motor components. Please note
that any parts damaged by any type of contamination will not be
covered by warranty.
