5.5 Air Inlet Filter - Cyclonic
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 fi lter 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.
2.
If the blockage indicator still returns to red, the fi lter must be cleaned
or replaced as follows:
Note: Stop the machine before cleaning or replacing fi lter elements.
Cleaning the casing
1.
Unscrew the clamp retaining the end cover of the air fi lter and
remove it noting the position of the vacuator valve. Empty out
any dust or dirt and then re-fi t in the original position (vacuator valve
downwards)
Cleaning the element
The air fi lter is fi tted with a blockage indicator to show when the fi lter
requires cleaning. If this indicator shows red when the compressor is
operating then the fi lter must be cleaned or replaced as follows:
1.
Remove the end cover by releasing the retaining clips and withdraw
the fi lter.
2.
Clean the fi lter by blowing compressed air through the fi lter from the
inside outwards
3.
Replacement of the element/end cover is a direct reversal of the above
Filter elements should
replaced every 12 months
or sooner if restriction is
indicated by the blockage
indicator.

5.6 Alternative Oils
OIL:- The XK12 is supplied fi lled with GD AEON S68 synthetic oil. Other ISO
68 Poly alpha Olefi n (PAO) grade oil with EP (extreme pressure) additives can
theoretically be used, but may aff ect 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 68 EP grade oils from
diff erent manufacturers can be
mixed.
