Step 7:
Installation of seat pad (57) and round tube (70) and seat support (13).
1. Adjust the seat pad (57) on seat support (13) so that the threaded holes
in the rear of seat pad (57) are align with the seat support (13) and screw
it tightly by using screw M10x70 (91) and washer 10//22 (17).
2. Slide the round tube (70) into the seat support (13) in middle position
and slide two foams (67) onto the ends of round tube (70).
3. Place the seat support (13) into appropriate holder of centre support (3)
and screw it tightly by using screw M10x70 (91), washer 10//22 (17) and
nuts M10 (18). Then put a screw cap (19) onto all screw heads (16+91)
and nuts (18).
Step 8:
Installation leg curler (14) and short round tube (80).
1. Put the leg curler (14) with pre-assembled steel bearings 1 (26) into the
appropriate holder of seat support (13) and screw it tightly by using screw
M12x85 (52) and self locking nut M12 (124). Attention, the leg curler (14)
should move easy when it is assembled. Then put a screw cap (51) onto
all screw head (52) and nuts (54).
2. Slide the short round tube (80) into the holder of leg curler (14) in middle
position and slide two foams (67) onto the ends of short round tube
(80).
3. Put the pulley unit (89A) together as figure shows. That means: Insert
a pulley (23A) into the pulley holder of leg curler (14). Put a washer (20)
onto the screw M10x45 (90), put the screw (90) through the pulley holder
with pulley (23A) and tighten it with washer (20) and nut (18) so that the
pulley (23A) can move easy. Then put a screw cap (19) onto all screw
heads (90) and nuts (18).
