> They are top-heavy, so be careful there. If memory serves,
Normally the standard under an RK07 is empty, which is what makes them
very top-heavy. if you want to remvoe the drvie from the stand, take off
the doors and side panels, then there are 4 screws that go up fron
underneath through the top fo the stand into the drive.
I cna't lift an RK07 drive on my own, it's a stagger-job for 2 people
IMHO. If ytou are stuck moving one on your own. it's possible to take it
apart into carryable bits without disturbing any alignment, but it's a
bit of work. Let me know if you want me to talk you through it.
> RK06/07 drives don't have a manual head locking mechanism.
There's an emergency-retract battery (IIRC 8 NiCD cells) which will
almost certainly be flat, but more importantly, there's a head lock
solenoid which will automatically lock the positioner in the home
position when the power is turend off. THere's nothing you have to lock
by hand when moving a drive.
