If you have a sight
window look to see if the oil lever is up to the mark.? If it is that
old I would drain and replace the oil.
Make sure the ballast valve is not fully open so you are not just pumping
through the valve and not the system. I would start with the valve fully
closed and then if you have trouble with water getting in your oil and making
it froth up and lose pumping speed you can begin opening he valve is stages.
It is best to let in dry air if it is available.

Hi
all,
?
I'm new to this
group - looks like some of you have some fancy rigs I could only dream of.
AnywayI've just dug out a very old Edwards single stage speedi-vac pump,
model 1sc50, which has been on the shelf for many years. When I started it
up, it did not produce hardly any vacuum ( only an absolute pressure of
about 600 mbar, which is useless!!!). Before I start stripping it down, I
was wondering if anyone had or could point? me towards a manual? This
pump is probably?around 50 years old, but I remember it being
refurbished by Edwards around 1975 and it hasn't been used since
then.
?
many thanks in
anticipation,
?
James
