Air Inlet Filter

The blockage indicator is designed to show/hold the maximum inlet blockage

encountered. It is set to show 100% blockage when the inlet depression reaches

37mbar. The filter element should be replaced/cleaned before the indicator enters

the red portion of the blockage scale.
If the indicator valve has entered the red portion of the scale:
1.

Press the reset button and re-check with the compressor operating.

If the blockage indicator still returns to red, the filter must be cleaned or

replaced as below.

Note: Stop the machine before cleaning or replacing filter elements.

Cleaning the filter casing / element

The air filter is fitted with a blockage indicator to show when the filter requires

cleaning. If this indicator shows red when the compressor is operating then the filter

must be cleaned or replaced as follows:
To clean the casing, it may be necessary to unbolt the filter casing from the vehicle.
1. Remove the top cover by releasing the retaining latches and withdraw the

filter element.

2. Clear any dirt/debris from inside the casing and the top cover.

3. Clean the filter element by blowing compressed air through it from the inside

outwards.

4. Replacement of the element/top cover is a direct reversal of above.

Filter elements should be

replaced every 12 months or

sooner if restriction is indicated

by the blockage indicator.

5.6 Alternative Oils

The TR20 is supplied filled with GD AEON S150 synthetic oil. Other ISO 150 Poly alpha

Olefin (PAO) grade oil with EP (extreme pressure) additives can theoretically be used,

but may affect the long term reliability of the machine. All oils should be checked

that they are mixable with both mineral and other Synthetic PAO variants used

without a reduction in performance.

ISO 150 EP grade oils from

different manufacturers can be

mixed.
