Fit the 3 threaded support bolts
Fit the three M5 x 80mm threaded machine screw bolts (which support the springs) to the plinth topboard as shown
below. Only “nip” the nuts tight by a maximum of 1/8 th of a turn after finger tightness has been achieved and they
start to clamp onto the wood. You will probably need to check these have not slackened off after about 2 months as they
tend to “bed into the wood initially.

Fit Bearing house
Fit the bearing house to the sub-chassis as shown below - only "nip" the nuts tight with a pair of pliers - more force than
this is detrimental to performance - the top of the bearing house should be between 3mm and 8mm from the top of the
bearing house nut – 3mm is probably ideal. Please note that ALL the bolts on the Sub-chassis assembly are carefully
torqued to a correct tension at factory – DO NOT TIGHTEN ANY ALLEN BOLT SETTINGS OR IT WILL
DEGRADE THE PERFORMANCE. ”. The sub-chassis is attached to the “spring plate” by one “pivot bolt” - the two
plates should be free to swivel and are loosely restrained by an “anti-rotate bolt” - this locating bolt on the side of the
sub-chassis should not be tightened at all. The pivot bolt is tightened at factory and should not be tightened or the
performance will degrade significantly.
