STEP 3
Seat and Leg Extension Assembly
8
1. Slide the Seat Slider (10) onto the Seat Support (7) and then attach the Handle Set (14) and Seat
Support (7) to the Base Frame (1), using two 1/2" X 3-1/4" Hex Bolts (102), four 1/2" Washers (121)
and two 1/2" Nylon Nuts (129).
2. Attach the Leg Extension Arm (18) to the Seat Support (7) by aligning the holes and then inserting
the Leg Extension Axle (49). Fasten the Leg Extension Axle (49) using two 5/16" Washers (124),
two Spring Washers (123) and two 5/16" X 5/8" Inner Hex Screws (117). Double check two
bearings pre-assembled on the Leg Extension Arm (18) at factory by pulling the "u" shaped spring
pin and making sure it rotates freely.
3. Insert a Foam Roller Holder (32) into the tube on the front of the Seat Support (7). Insert a Foam
Roller Holder (32) into the tube on the bottom of the Leg Extension Arm (18). Slide a Plastic Cover
(69) onto each end of the Foam Roller Holders (32). Mount the Foam Pads (56) to the Foam Roller
Holders (32).
TIP:
Moisten the center of the Foam Pads (56) with water to make it easier. Secure
the Foam Pads (56) with Plastic Washers (69) and Set Screws (99). Tighten the pre-installed 5/16"
X 1/4" Set Screw (119) with an Allen wrench to help hold Foam Roller Holder (32) in place.
4. Slide the Seat Hinges (22) onto the Seat Slider (10) as shown. Screw the Seat Pad (54) to the
Seat Hinges (22), using two 3/8" X 1" Hex Bolts (112) and two 3/8" Washers (122).
5. Attach the Back Support (9) to the Seat Slider (10), using one 1/2" X 3-1/2" Hex Bolt (101), two 1/2"
Washers (121) and one 1/2" Nylon Nut (129). Attach the Flat Position Support (19) to the Back
Support (9), using one 1/2" X 3-1/4" Hex Bolt (102), two 1/2" Washers (121) and one 1/2" Nylon Nut
(129).
Note:
Use the Flat Position Support (19) when the bench is in the flat position. Fold it away
when bench is in incline or decline positions. Attach both Back Support Plates (20) to the Back
Support (9) and to the Base Frame (1), using (on each end) one 1/2" X 5-1/4" Hex Bolt (100), two
1/2" Washers (121) and one 1/2" Nylon Nut (129). Tighten these bolts, and then loosen just enough
to allow the Plates to pivot while sliding the Seat Slider (10).
6. Attach the Back Pad (55) to the Back Support (9), using two 3/8" X 2-3/4" Hex Bolts (109) and two
3/8" Washers (122). Plug both ends of the Back Support (9) with a 50mm SQ Plug (66).
