I have just purchased an RL02 and while waiting for it to arrive, I am wondering what to
do for cleaning and lubrication before power-up. I don't know how long it's been
sitting (indoors). I have downloaded the manual from bitsavers. I know there has been some
discussion on this list recently but I think that was on the care and feeding of
RK05's...
Also, the seller tells me he can't get the pack out:
When I had the disk pack cover off, the release handle
on the pack did
not release the disks and I did not want to force it. Does the drive
need to be powered on and is there a way to remove them without powering
it on?
He does know about the shipping screws and will install them before Fedexing.
So, what should I do first?
thanks for any assistance.

You can't open the lid, unless you open a little hatch on the right-hand
side and trip the catch by hand.
As for removing the pack, you need to slide the slidey bit on the handle
across and then pull it up to break the clamp's hold on the pack.
You *can* just pull it straight off, but I wouldn't recommend it...

If that unit has one. The little hatch does not appear on all drives.
For those units that need opening (to dismount a pack, typically)
that one _can't_ pop the hatch then pop the lid latch, I find it's
possible to remove the 4 screws on the rear deck (the fixed part of
the top surface), then carefully lift up and wiggle on things until
it's possible to get the lid open.
It's hard to describe how to do it exactly (especially since I don't
have a drive in front of me), but if you just remember not to force
anything, you shouldn't break anything.

Naturally. Of course, I have seen 3rd-party packs that are different
(just lift?) but a real RL02K does need to have the thumb slider
engaged when lifting the handle to cause the pack to release the
spindle.

Ooh... never tried that (and never would try it!)

The pack is held onto the spindle with a fairly strong magnet. As long
as the heads aren't extended into the pack (which would be very bad
anyhow), he should be able to just pull harder and get the pack to
release. When I first removed an RL02 pack, it required more force
than I was expecting.

Yes, but it's also possible that the pack thumb latch is sloppy or
broken. I have seen that. With experience, you can tell that the
release mechanism has or has not engaged and try another cycle of the
latch and handle. For someone who is not used to it, it may or may
not be easy to tell on a dodgy pack. This is presuming that they know
how to use the handle in the first place, a "skill" that I wouldn't
assume of someone who has never seen an RL02 drive before (no idea if
the seller is an old user selling stuff, or someone who has zero
experience with 1980s DEC hardware)

Don't forget the little slider on the handle. Lifting the handle on its
own won't do a darn thing (this is so you can carry a pack by its handle
without the cover dropping off). What you do is slide the little slider
on the handle along (it will only move one way), and while holding it in
that position, lift the handle. That will pull the hub off the magnet and
let you remove the pack.
