Fit the outer four frame connectors H23
with four hex screws M3x25 D336 on the
lower frame and add Loctite to the
threads.
Next pull the hex screws out so they just
dissapear into the connectors.
Push two inner connectors H22 bet-
ween the outer ends of the upper frame.
Then slide the upper frame between the
connectors of the lower frame so that
the screws are in line and push the hex
screws into the holes. Do not tighten the
screws at this stage.
As soon as the rear connector is assem-
bled the hex screws can be tightened. You
will probably need a second 2.5mm hex
driver for this.
