Assembling the D400
Your D400 is supplied in two cartons. Unpack these and check
the parts against the list at the beginning of this manual.
 Assemble the air rotor by sliding together the keys and
mortises at the hub of the five air blades.
 Take the white, powder-coated hub plate, pass two 5mm bolts
and washers through the inner holes, and fit the rotor hub
spacer over the 5mm bolt heads.
 With the body of the wind generator on its back, offer the hub
assembly up, and slide it onto the alternator shaft.
 Align holes in the rotor hub spacer with the 6mm holes in
the alternator shaft and secure with two 6mm cap head alan
bolts provided .
Its vital that a smear of threadlock compound is applied to
the threads to prevent the bolts from working loose in
operation.
* Take care not to overtighten these bolts * as this can
cause the air rotor to run out of ‘true’.
 An aluminium ring is provided to locate the blade roots
securely. The ring is inserted, rounded side first, into the
moulded annular recess on the rear of the blade roots.
Offer rotor blade assembly up to rotor hub spacer and slide into
place.
 Ensure that the rotor assembly is fitted the right way round.
The annular groove on the blade roots should face the rear (tail
end) of the machine, and the face with the 10 conical holes in
the blade roots should face forwards.
 Fit outer stainless steel hub plate, place nuts and washers on
inner 5mm bolts and tighten gently.
 Rotate air rotor in relation to hub until the five blade securing
holes align.
 Pass a 5mm bolt through the inner powder-coated plate such
that it passes right through the rotor blade and outer hub plate,
fitting a washer and nut each time.
 Finally, evenly tighten all fasteners.
Note that the rotor should only be secured using new nyloc nuts.
