Fit the first screw to approximately half its
depth.
Fit the other three screws, again, to half
their depth. The alignment of these holes
can sometimes be tight due to the powder
coating. If the screws do not align with the
threaded inserts, do not force it, but open
up the case top holes with a 3.5mm drill bit
before re-trying. Once all the screws are in,
you can tighten them all down to the case.
Again, do not over-tighten.
With the case top secured, you can now
tighten the jack nuts. You can either use a
large pair of pliers, adjustable spanner or
13mm spanner/socket. Just be careful not
to scratch the powder-coating with
whichever tool is used.
You can now invert the case and add the
stick-on rubber feet. One in each corner.
