Bought a stanley air compressor today.

Noticed the manual talks of a safety valve with a ring that you can pull to check the valve is operating correctly/not stuck.

I checked mine and there is no ring to pull.

I went back to store and explained and they opened another box and it was the same.


I've emailed Stanley, but what do people think?

Generally a stem sticking out the top hole with a pull ring or knob which manually lifts the sprung seal.

Maybe search the model of the part see if it's meant to be like that.

Anything in the box which is meant to be fitted into it?

Exactly what I expected. Nope looked through everything. Videos online visibly show one. But they are 1yr + old so I wonder if this is a non-testable version?

Other one in the shop didn't have one, guy went off and took a photo and showed me.

Instructions mention all parts included to attach, and the ring isn't one of them. So not something were meant to put on ourselves.

The hole in the top isn't threaded either, so it's not as if you could screw something in.

I guess I wait to hear from Stanley. End of the day it's a safety on a safety.

The machine cuts off at 8bar as it should. The valve is rated for 8bar, so I'm not too fused I can't check the valve is working. I'll just keep an eye on the pressure gauge anyway until I hear from Stanley.
 
I can see your point, but having worked around compressors for over 30 years, most don't have the facility to check the valve, nor have I ever done so, so I wouldn't worry too much if they've just changed the spec without updating the manual.

Thanks. That's reassuring. Other than this minor query I'm impressed. Lockdown has made my garage a real man's garage lol.
 
I bought a compressor from SGS a few months back and noticed the same, dug around and on the bottom of the sales page it had a starred note

Due to a change in EU legislation the safety valve rings have been removed by ALL manufacturers of air compressors. This is due to the ring being incorrectly used to vent the compressor, causing undue wear which should not be present on a safety device. The air should drained from the tank via the valve on the belly of the tank. This location is used so that the water is drained at the same time.

And this is why forums are great.

Amazing stuff.
 
Empty the tank by venting the compressed air using a standard pistol grip nozzle or similar before loosening the condensation drain plug at the bottom of the tank.

If you loosen the condensation drain plug with the tank under pressure, you just blow all the crap on your garage floor all over the place.

Guess who learnt that lesson the hard way...
 
:D My lesson this week was the drain plug can get blocked, which meant not much air was being drained, silly me carried on unscrewing thinking it would start releasing until I ran out of thread! An hour I took to find the plug :rolleyes:
 
My 30+ year old compressor (Wolf )sprung a air leak on the bottom of the tank - turned it upside down and I could just poke a screwdriver through the metal - Big tip is drain it regularly - It never had a lot of use so I neglected it a bit. -
 
I drain mine off after each use and its surprising that after only a few months the small amount of water that comes out is rusty orange.
 
Aw crap. I've not drained (or used) mine since we moved a year ago. Interestingly mine does have that ring pull thingy that we're talking about but I've never actually pulled it.
