Attach two 8mm Metal Spacers (97), a 60mm
Metal Spacer (39), and two Bearing Wheels (46)
to one end of the Seat Carriage (12) with an M8 x
104mm Bolt (60) and an M8 Nylon Locknut (65)
as shown.
Be sure the parts are oriented as
shown in the inset drawing; the Seat Knob
(not shown) will not engage the Bench Rail
(not shown) if they are incorrectly oriented.
Do not overtighten the Locknut; the Bearing
Wheels must be able to roll easily.
Attach two Bearing Wheels (not shown) to the
other end of the Seat Carriage (12) in the
same manner.
10. Attach the Seat Knob (45) to the Seat Carriage
(12) with two M6 x 13mm Bolts (92) and two M6
Nylon Locknuts (69).
Be sure that the slot in the
Knob is aligned with the slot in the Seat
Carriage, as shown.
Orient the Seat (13), the Seat Backing (9), and
the Seat Carriage (12) as shown. Attach the Seat
and the Seat Backing to the Seat Carriage with
four 1/4” x 16mm Bolts (82).
11. Pull out the Seat Knob (45) as far as it will go, and
set the Seat Carriage (12) on the Bench Rail (5).
Loosely attach two 8mm Metal Spacers (97), a
60mm Metal Spacer (39), and two Bearing
Wheels (46) to the center holes in the Seat
Carriage (12) with two M8 Flange Nuts (19) and
the M8 x 114mm Axle (57).
Make sure that the
serrated edge of the Flange Nuts are against
the Seat Carriage.
While a second person presses down on the Seat
(13), hold the wheel assembly firmly against the
bottom of the Bench Rail (5) and properly tighten
the M8 Flange Nuts (19).
Make sure that three
threads are extending past the Nut, and that
the wide sides of all six Wheels (46) are
pressed against the Bench Rail.
Engage the Seat Knob (45) into an adjustment
hole in the Bench Rail (5).
