5. MAINTENANCE & TROUBLESHOOTING
Before carrying out any maintenance, switch compressor off, unplug it from the mains electricity supply, depressurise the
tank and allow unit to fully cool down.
5.1. Keep the compressor clean and free of dust. Do not use cleaning agents. Wipe the compressor using a slightly dampened cloth and
blow it over with compressed air, if available.
5.2. Ensure that the ventilation openings are clear. DO NOT allow any extraneous material to enter the unit via any of the ventilation
openings.
5.3. To prevent corrosion to the tank, drain it on a regular basis by opening the drainage tap at the bottom of the tank, after draining ensure
the drainage tap is fully closed.
5.4. The troubleshooting guide below is intended to give an indication of the type of fault which may develop with the compressor over a
long period of service. The chart is not intended as a guide on how to repair the fault, it is recommended that the compressor is
returned to an authorised service agent for rectification of serious faults.
5.5. 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.

b) The larger gauge (figs.2.4 & 3.4) indicates the pressure inside the main tank. The smaller gauge (fig.2.5 & 3.5) indicates the
pressure supplied to the air equipment. The pressure switch (figs.2.7 & 3.7) stops the motor when the maximum tank pressure is
reached and restarts it when pressure falls below the minimum threshold - approximately 2bar (29psi) less than the maximum
pressure.
 WARNING! For this reason DO NOT tamper with, or adjust, the pre-set switch or safety valve.
c) Should there appear to be any loss of efficiency when using the compressor, ensure first that the air tool is clean and functioning
properly. If the air tool is satisfactory then refer to the trouble shooting guide.
4.6. DO NOT leave the compressor running for any length of time with the air tool attached, but not being used. If there is a pause in the
work, switch the compressor off. These compressors have a duty-cycle of 25%. For each period of use, a rest period of three times
that length should be left before using it again (for example: after 2½ minutes use, a rest period of 7½ minutes should follow). If the
motor over-heats, the thermal cut-out will operate and cut the motor out. When the temperature has returned to normal, the motor will
re-start automatically.
4.7. If the operating note of the compressor changes, there may be a blockage within the tool, or the air hose may be pinched. The unit
should be switched off immediately, and the source of the blockage investigated and eliminated, before re-starting.
4.8. When work is complete, switch the compressor off. by pushing the switch to the off position (SAC00015 - Fig.1.6) or pushing the red
on/off switch downwards (Figs.2.6 & 3.6). operate the air tool to clear any pressure left in the air hose. Disconnect the air tool from
the compressor. For models with air tanks, vent any pressure remaining in the tank by manually operating the pressure relief switch
(pull on the metal ring) situated next to the pressure switch assembly. open the drainage tap at the bottom of the tank, to allow any
moisture to be drained from the tank. This prevents corrosion on the inside of the tank. Close drainage tap.
4.9. If it is intended to store the compressor away, allow it to cool before storing it carefully in a safe, dry, dust free, childproof location.
Environmental Protection.
Recycle unwanted materials instead of disposing of them as waste. All tools, accessories and
packaging should be sorted, taken to a recycle centre and disposed of in a manner
which is compatible with the environment.
When the product is no longer required, it must be disposed of in an
environmentally protective way.
Fault Possible Cause Remedy
Air leakage from the valve of the pressure
switch whilst the compressor is off.
Pressure switch valve, due to wear or dirt
on the seal, does not perform correctly.
Unscrew the head of the valve, clean the valve seat
and the rubber disc (replace if worn).
Reassemble and tighten carefully.
The compressor does not stop and the safety
valve is tripped.
Reduction in performance. Frequent start-up.
low pressure values.
Irregular functioning of the compressor or
broken pressure switch.
Excessive air consumption, leaks from
the couplings and/or pipes.
Switch off compressor and contact
Authorised Service Agent.
Clean the air vents and ensure the work area is
ventilated. Do not over-run the compressor's duty
cycle.
Air tool requires higher spec. compressor.
Check / replace the seals of the fitting.
The compressor stops, then restarts
automatically after a few minutes.
Tripping of the thermal cutout due to
overheating of the motor.
