R270 Feet and Spikes
Your R270
HD
will come with rubber feet inserted into the plinth inserts (pictured below). This
is for use on hard floors or when spikes are inappropriate to use.
HD
If you wish to use spikes, you
can remove the rubber feet by
simultaneously twisting and
pulling them.
The threaded inserts in the
plinth will be revealed when
the rubber feet are removed.
Take the spikes and twist
them in a clockwise direction
in to the plinths. Ensure they
are fully inserted and stand
the cabinet up and place it
in it’s final location to see
if it is stable and level. If
it is not adjust the spikes
accordingly and then
tighten the knurled locking
nut to hold the spikes in
that position.
