[BlindHandyMan] Setting air compressor gage

[Agent86b]

Hi all,
has anybody found a way of setting the air pressure to the correct
PSI for particular tools?
For example my air drill must run at 90 PSI, but my compressor tank
is factory set to 115 PSI.
I can get my sited wife to come and read the two gages to tell me
what I have, but I would rather do it myself. Otherwise I must wait
for her to come home before using a different tool.
Thanks for any advice.
Max.
