2. Slide a Plastic Cap (104) onto each side of the R and L Leg Extension Arm (21R
& 21L), flat side to the outside. Slide a Foam Pad (65) onto each Leg Extension
Arm (21R & 21L), then cap with an Aluminum Cap (105) and secure with a 5/16"
X 1-1/4" Screw (149).
3. Insert 1" Foam Roller Holder (40) into the Leg Extension Assembly (20) and
secure with the two 5/16" X 1/2" Set Screw (157). Slide a Plastic Cap (104) onto
each side of the 1" Foam Roller Holder (40), then cap with an Aluminum Cap

4. Attach Seat Pad (63) to Seat Adj. Handle (11), using two 3/8" X 1-3/4" Hex
Threaded Bolts (135) and two 3/8" Washers (163). Attach Seat Adj. Frame (12)
to Seat Adj. Handle (11) using two 3/8" X 1 " Hex Threaded Bolts (137) and 3/8"

the Seat Adj. Frame (12) over the top the Seat Spring (99) and into the Main
Frame (1). You may loosen the pre-assembled Tighten knob (127) to allow the

(127) to eliminate wobble in the seat after you have adjusted the seat to the
desired height. Screw the Pop Pin attached to the Longer Clutch Cable (71) into
the receptor in the Main Frame (1). If the Seat Spring (99) interferes with this,
you may need to rotate the spring a bit until it does not interfere.
