Step 3:
Installation of end tube (7) and top cross beam (6).
1. Place the end tube (7) onto the ends of guide bars (5) and screw them
together by using screw M10x25 (85) and curved washer 10//22 (17).
2. Insert a pulley (23) with 2 cable slides (22) into the pulley holder of top
cross beam (6). Put a washer (20) onto the screw M10x45 (90). Then put
the screw (90) through the pulley holder with pulley (23) and tighten it
with washer (20) and nut (18) so that the pulley (23) can move easy.
3. Screw tightly the top cross beam (6) at end tube (7) by using screw
M10x65 (16), curved washers10//22 (17) and nut (18). Then put a screw
cap (19) onto all screw heads (16+21+87) and nuts (18).
4. Put the top cross beam (6) in appropriate position onto the centre support
(3) by using screw M8x20 (87), screw M10x65 (24), washers (17+64) and
