STAN D

The stand lor the Ferrograph $1 loudspeaker is a special single-
pillar design. the teat being fitted with swivelling castors for
complete freedom ol movement. it is constructed of aluminium
tor lightness combined with strength and has been designed in
sections for ease ol packing end for convenience in transit. The
instructions for assembly are given below.

Assembly

Either end oi the draw bolt should be screwed into the centre
at the upper support arm lor approuimately 1 inch. when the
end will be recessed about I inch from the flat surface. The
support pillar should he slid over the draw bolt and the single-
slotted and located in the circular recess in the centre boss ol
the upper support arm. It should be rotated until the slot locates
on the key. then pushed lully home.

For convenience. the upper support arm should be stood on a list
surlace and the lower support arms inserted into the slots in the
support pillar as shown in the diagram. The cone sleeve should
now be slid onto the draw bolt as lat as ponible and held in place
by the loclutut. which should be adjusted linger tight. The
locking collar can now be pushed over the end of the support
pillar to locate in the cut-out of each lower support arm and
tapped gently into place. The locknut can now be tightened until
the support arms are held lirmly in place and the whole structure
is rigid. The not should not be overtightened as this would only
place undue strain on the support pillar and draw bolt.

Finally the stand should be lastened to the loudspeaker cabinet
using the hexagonal heeded screws and washers provided. It will
be lound most convenient to do this with the cabinet upside
down (on a soft surlace to avoid marking the cabinet top) or on
its side. The screws should be inserted by hand into the captive
nuts on the bottom 0! the cabinet and made linger light. They

should then be tightened gradually in turn until the stand is held
lirmly to the cabinet. Again. overtightening should be avoided.

An alternative method is tor the upper support arm (with the draw
bolt correctly inserted) to be lastemd to the loudspeaker
cabinet at the start. The rest ol the assembly will then proceed as
described above.
