The time has come for me to change the oil in my Sil Air 15, and having read the instructions, I am non the wiser as to how I should do it.

This is the compressor, and the Silentaire site has the usual user manuals, but I am getting stuck on the plastic hoses that I have to disconnect before tipping the compressor to remove the oil.

Manual here (http://www.silentaire.com/silentaire/images/pdfs/General%20User%20and%20Maintenance%20Guide.pdf)

If anyone else owns one and has completed an oil change, I would appreciate some help.

Hi Martin,

This may seem a stupid question but did you take the cover off first?

How is it that you know that the oil needs changing?

No such thing as a stupid question... ;)

The cover has been removed and inspecting the oil level window shows it is less than half full and slightly discoloured. When I open the tank pressure release valve, the water droplets are milky and there is oil being sprayed out of the side at the safety valve. Both signs of needing a change, together with having moved house and more than 150 hours spraying time.

Ok,

So what I can tell from your instructions and you having the "SIL-Air" model, it looks like you take off the air filter(thing) tip it up so the oil pours out, then put in new oil. Kind of a pain it looks like. Anyway thats what I can tell from the drawings in the instructions. Have you tried finding a site online to get better detailed instructions?

Ok, its early and I just re-read your first post. I don't think you are supposed to remove the hoses, just the air filter? Can you take a pic without the cove so we can see the tank and the hoses?

HTH

Minus the cover with some dust (must get cleaning)

The offending oil level

The safety valve that spits a tiny amount of oil each shut off cycle.

Someone on M-L already suggested that it is easier (his method) to remove the glass and tip the oil out from there, as long as I am careful to not damage the threads. Sounds like a decent way to do it.

Hi Martin
As I se it and according to the manual You shuld remove the airfilter and the small black plasticcap from the suction tube and first drain the old oil out from there,when it's empty then fill with new oil through the same suction tube and then reinstall airfilter and plastic cap.

This also sounds like probably the easiest way since it's more clear as to how to do it.
