release all air from the tank (Except for 5.4a).
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 5.5a. below.
5.2. OPERatiONS tO bE CaRRiEd OUt WEEKlY:
a) Drain condensation by opening the valve located in the front leg (fig.6). Place a container under the valve and open the valve by
turning anti-clockwise.
 WaRNiNg!take care if there is compressed air in the tank, as water could flow out with considerable force. recommended pressure
1 - 2bar max.
5.3. OPERatiONS tO bE CaRRiEd OUt EvERY 50 hOURS
a) check oil level and if necessary, top up.
b) check for oil leaks.
5.4. OPERatiONS tO bE CaRRiEd OUt EvERY 100 hOURS:
(or more frequently, if the compressor operates in a very dusty atmosphere):
a) turn off the compressor and remove the top cover by removing the four bolts. remove the air filter element (fig.7). using stored
air from it'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. replace top cover.
b) check the automatic cut-out at max. pressure and the automatic cut-in at 2bar below.
5.5. OPERatiONS tO bE CaRRiEd OUt EvERY 500 hOURS:
a) replace the lubricating oil. for oil specifications see 5.6. remove the top cover
(4 bolts) and the side cover (4 bolts). remove the dipstick/breather plug then unscrew
the oil drain plug (figs.2 & 3), drain the oil into a container. If possible 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/breather.
b) replace air filter (see 5.4a. for access).
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.
5.6. 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.

iMPORtaNt WaRNiNg - Air contaminants taken into the compressor will affect optimum performance.
Example: Body filler dust or paint over-spray will clog the pump intake filter and may cause internal
