NOTE:
A: If the motor does not cut in and out, but runs continuously when using an air appliance, the capacity of the compressor may
be too small for the equipment or tool.
B: The direct pressure gauge (fig 5) indicates the pressure inside the main tank. The regulated pressure gauge (fig 5) indicates the
pressure supplied to the air equipment.
Should the pressure in the main tank exceed the pre-set maximum, the safety valve (fig 3) will activate.
WARNING! For this reason DO NOT tamper with, or adjust, the pressure switch (fig 6) or safety valve (fig 3).
5.7.7.
The compressor is fitted with a trip reset button, located on the side of the connection box on top of the motor (fig 3). Should the trip
reset button activate, leave for 1 minute before pressing the button to reset.
For possible causes of trip activation see section 6 Troubleshooting.
6. MAINTENANCE
In order to keep the compressor in good working condition, periodic maintenance is essential.
WARNING! Before performing any maintenance operation, switch off the compressor, disconnect from electricity supply and
release all air from the tank.
IMPORTANT! Failure to carry out maintenance tasks may invalidate the warranty on your compressor.
6.1.
OPERATIONS TO BE CARRIED OUT AFTER THE FIRST 5 WORKING HOURS:
A: Check that all bolts/nuts are tight, particularly those retaining the crank case and cylinder head.
6.2.
OPERATIONS TO BE CARRIED OUT AFTER THE FIRST 50 WORKING HOURS:
B: Replace the lubricating oil.
6.3.
OPERATIONS TO BE CARRIED OUT DAILY:
A: Drain condensation by opening the valve located under the tank (fi g 7). Place a container under the valve and slowly open the
valve by turning counter clockwise.
6.4.
OPERATIONS TO BE CARRIED OUT EVERY 100 HOURS
NOTE: Or more frequently, if the compressor operates in a very dusty atmosphere.
A: Check oil level and, if necessary, top up.
B: Remove the fi lter elements (fi g 4) and clean with compressed air (wear eye protection). DO NOT operate the compressor
without the fi lters as foreign bodies or dust could seriously damage the pump.
C: Check for oil leaks.
6.5.
OPERATIONS TO BE CARRIED OUT EVERY 200 HOURS:
A: Replace the lubricating oil. For oil specifi cations see 6.7.
Remove the fi ller cap (fi g 3) then unscrew the drain plug (fi g 3) and drain the oil into a suitable waste oil container.
Drain when the compressor is hot so that oil drains rapidly and completely. Incline compressor to ensure complete drainage.
Replace drain plug and refi ll through the oil fi ller aperture. DO NOT overfi ll. Replace fi ller cap.
B: Check the automatic cut-out at maximum pressure and the automatic cut-in at 2bar below.
WARNING! Never mix diff erent 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.
OPERATIONS TO BE CARRIED OUT EVERY 500 HOURS:
A: Replace air fi lter (fi gs 1 & 4).
B: Check all tube fi ttings and electrical connections.
6.7.
OIL
Recommended oil for compressors, suitable for room temperatures ranging from +5°C to +25°C.
SEALEY CPO or equivalent SAE 40 compressor oil. Room temperature below +5°C: SAE 20 compressor oil.
IMPORTANT WARNING - Air contaminants taken into the compressor will aff ect optimum performance. Example: Body fi ller dust
or paint overspray will clog the pump intake fi lter and may cause internal damage to pump/motor components.
WARNING! Any parts damaged by any type of contamination will not be covered by warranty.
6.8.
Inspection of pressure tank both inside and out.
Under the PRESSURE SYSTEMS SAFETY REGULATIONS 2000 it is the responsibility of the owner of the compressor to initiate a
system of inspection that both defines the frequency of the inspection and appoints a person who has specific responsibility for
carrying out the inspection.
