4. <strong>Maintenance</strong><br />
4.1 General<br />
Little maintenance of the equipment should be required other than regular <strong>and</strong> thorough<br />
cleaning of the machine <strong>and</strong> testing the vacuum system for leakage.<br />
Access to hidden components is gained by removal of the rear panel <strong>and</strong> should only be<br />
attempted after disconnection of the mains supply.<br />
Further work should only be carried out after discussion with <strong>Logitech</strong> <strong>Ltd</strong>., as removing<br />
the rear casing involves disturbing oil <strong>and</strong> electrical connections.<br />
4.2 Vacuum Pump – Potential Failures or Breakdowns<br />
(a) The most common interruption to normal operation is when the vacuum pump oil is<br />
contaminated <strong>and</strong> needs out gassed. See the vacuum pump manual for various<br />
settings.<br />
(b) Periodically check the oil level in the oil sight glass (5) <strong>and</strong>, if required, replenish with<br />
light vacuum pump oil as specified in the manufacturer's manual. The oil is applied<br />
by opening the oil filler cap (6) located on the top panel of the machine <strong>and</strong> topping<br />
up as necessary.<br />
(c) During the resin evacuation process, it is possible that contaminated vapours will<br />
gradually enter the pump. Whilst the pump is very tolerant of contamination, it is<br />
necessary to open the gas ballast control (7) (located on the top panel ) during this<br />
particular operation, thus introducing clean air into the system to purge the pump.<br />
(See pump manufacturer's manual for further information.)<br />
(d) Oil mist <strong>and</strong> fumes are channelled to the exhaust outlet at the rear of the machine.<br />
This may be connected to an extraction system or fitted with an Balston filter which<br />
can be supplied on request (Cat. No. 2VAC‐002).<br />
If the system failure cannot be found in the first instance contact either your local<br />
representative or the manufacturer for assistance.<br />
4.3 Vacuum System<br />
Periodically check the vacuum system connections, seals <strong>and</strong> "O" rings for wear <strong>and</strong> leakage,<br />
greasing as required. When necessary, repeat the vacuum check described in Section 2.3.<br />
