Insert one end of the weight belt (44) through the slot in the top plate belt clamp until approximately one inch of the free
end of the belt protrudes from the slot in the opposite side of the clamp.
While holding the free end of the belt, press down on the opposite side of the belt so it lays flat against the inside of the
clamp.
Insert the belt retainer (31) into the belt clamp. BE SURE the tapped hole in the belt retainer is aligned with the mating
hole in the belt clamp.
CAUTION:
BE SURE to keep the weight belt straight when installing the retaining screw (54) in the belt
retainer (31). Misalignment of the weight belt may bias the top plate, which can cause excessive contact of
the top plate shaft with the weights, resulting in excessive noise during use, and potential hazards to the
user or other bystanders.
Thread the retaining screw (54) through the belt clamp and into the belt retainer (31). Tighten the retaining screw to
400 inch-pounds.
Route the weight belt (44) over six pulleys, as illustrated.
Insert the free end of the weight belt (44) through the slot in the main frame belt clamp, and pull through the opposite slot
just until force is applied against the top plate (27). This will eliminate any slack in the belt and ensure proper tensioning.
While maintaining tension on the weight belt, press down on the free end of the belt so it lays flat against the inside of
the belt clamp.
Insert the belt retainer (31) into the belt clamp. BE SURE the tapped hole in the belt retainer is aligned with the mating
hole in the belt clamp.
Thread the retaining screw (54) through the belt clamp and into the belt retainer (31). Tighten the retaining screw to
400 inch-pounds.
Check for proper tensioning of the weight belt by applying lateral pressure to the belt at a point midway between two
pulleys. Deflection of the weight belt should be less than 25 mm. Loosen the retaining screw (54) and adjust belt tension
as needed.
5. Install the Seat and Back Cushions
Hold the back cushion (17) in place on the
main frame (2). Secure the back cushion to
the main frame with two screws (50) and
washers (65). Tighten the screws securely.
Hold the seat cushion (12) in place on the seat
frame. Secure the seat cushion to the seat
frame with four screws (50) and washers (65).
Tighten the screws securely.
Align the two drilled holes in the left handle
(18) with the mating holes in the seat frame
(4). Insert two screws (54) with washers (70)
through the handle and seat frame to
maintain the parts in position. Slide the right
handle (19) onto the two screws (54), and
secure the frame and handgrips together
using two washers (70) and nuts (68). Tighten
the nuts securely.
Place the flywheel cover (13) with mounting
bracket (9) (factory installed) on the range-of-
motion flywheel (8).
Align the two drilled holes in the mounting
bracket (9) with the mating holes in the main
frame (2). Secure the mounting bracket to the
main frame using two screws (56), four
washers (70) and two nuts (68). Tighten the
nuts securely.
Secure the flywheel cover (13) to the range-of-
motion flywheel (8) using one screw (59),
washer (73) and washer (70). Tighten the
screw securely.
