every 1000 hours. operations to be carried out :
a) replace the lubricating oil. for oil specifications see 5.8.
remove the oil breather (fig.6.A) and drain screw (fig.6.B), draining the oil into a container. Drain when the compressor is hot so that
oil drains rapidly and completely. Wash breather in kerosene, fuel oil or similar.
replace screw 'B' and refill through the filler aperture. Do not overfill. replace breather.
WArning! never mix different oils and do not use non-detergent/low quality oils as compressor may be damaged.
WArning! Dispose of waste oil only in accordance with local authority requirements.
b) check belt tension. A force of 3kg applied at the belt mid-point should give a deflection of approx. 10mm (fig.7). if adjustment is
required remember to maintain the alignment of the two pulleys (fig.7). Adjust by repositioning motor.
c) check all tube fittings and electrical connections.
d) inspect pressure tank inside and out for damage or corrosion.
