WHEN WORK IS COMPLETE.
At the end of each working day, drain any moisture from the main tank. Place a container
under the drain plug and then carefully unscrew it (fig.5). DO NOT allow moisture to
accumulate in the tank as this will corrode the inside of the tank and affect the pressure.
WARNING! Wear safety goggles when performing this task.
6. 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 Service and maintenance must be performed by an authorised agent. DO NOT tamper with, or attempt to adjust, the pressure
‰
switch or safety valve. Before moving, or carrying out any maintenance on the compressor, ensure that the ignition switch is 'off', that the
air tank pressure has been vented and the compressor has been allowed to cool down for a period of time.

Check that all bolts/nuts are tight, particularly those retaining the crank case and cylinder head.
Replace the lubricating oil - see section 6.2.5.
Drain condensation by opening the valve (fig.5) located under the tank.
Check oil level (fig.6.B) and, if necessary, top-up.
Check guards/covers are secure.
Check for oil leaks.
Check for unusual noises or vibrations.
Check for air leaks.
(or more frequently, if the compressor operates in a very dusty atmosphere):
Remove the air filter element by undoing the screw (fig.7.A) and removing the filter cover. Clean the filter by
blowing through from the clean side, with an air line at low pressure. Replace filter, cover and screw. DO NOT operate
compressor without filter as foreign bodies or dust could damage the pump.
WARNING: Wear safety goggles when performing this task.
Clean compressor.
Check the automatic cut-out operation at maximum pressure and the automatic cut-in at 2 bar below.
Check belt tension. A weight of 3kg applied at the belt mid-point should give a deflection of approximately
10mm (fig.8). If adjustment is required, maintain the alignment of the two pulleys (fig.8). Adjust by repositioning the
engine, using the screw adjuster provided in the base plate.
Change air filter element.
Replace the lubricating oil. For oil specifications see 6.4
Remove the oil filler cap (fig.6.A) and (after placing a suitable container under it) the oil drainer (fig.6.B). Drain
when the compressor has been recently run, so that the oil drains rapidly and completely. Replace the oil drainer and
refill through the filler aperture. DO NOT overfill. Replace the oil filler cap.
Check all tube fittings and electrical connections.
Inspect pressure tank inside and out for damage or corrosion.
