[. . . ] Setup for AC1 & AC2 (See Drawing #3): 1) Set the pre-load on the rear shock so it compresses 12mm while the rider is sitting on the bike (in riding gear). To measure the travel, position the rubber top out bumper (C) on the shaft of the shock to measure the amount of compression/movement. 2) If the shock moves less than 12mm, reduce the pre-load on the spring by turning the spring preload collar (E) counter-clockwise. 3) If the shock moves more than 12mm, increase the pre-load on coil spring by turning the spring preload collar (E) clockwise. 4) If you need to turn the shock collar more than six turns from the zero preload setting to achieve the proper amount of pre-load, you need a heavier spring. 5) Tune rebound (G) and compression damping (H) to personal tastes(see Shock Basics and Terminology). 6) If you have difficulty with set-up, please see your Authorized Giant Dealer. Drawing #3 8 Setup for AC Air (See Drawing #4): 1) For initial setup, set the positive air chamber (B) to the rider's weight set the negative air chamber (A) to the riders weight minus 20 psi. (for example if the rider weight is 150 lbs, set the positive air chamber to 150 psi. NOTE: The negative air chamber can never have more air pressure than the positive air chamber. This will result in poor bicycle performance and cause premature wear of the shock. 2) To measure the travel, you can position the rubber "O" ring (D) on the shaft of the shock to measure the amount of compression/movement. 3) If the shock moves less than 12mm, reduce the air pressure by 10 psi. in the negative air chamber (A) followed by the positive air chamber (B). 4) If the shock moves more than 12mm, increase the air pressure by 10 psi. in the positive air chamber (B) followed by the negative air chamber (A). 5) Tune rebound damping (C) to personal tastes(see Shock Basics and Terminology). 6) If you have difficulty with set-up, please see your Authorized Giant Dealer. Drawing #4 9 Travel settings: Your AC bicycle gives you the ability to change the travel from 4. 5" to 5. 15" to 6" with minimal effort. This is accomplished with three positions of the upper shock pivot bolt (see Drawing # 5). Pivot the shock backward or forward to align the eyelet with one of the three holes. The forward most position is 4. 5" travel, the middle position is 5. 15" travel, and the rear position is 6" travel. Install the bolt and tighten to the proper torque of 100-120 Kgf/cm (86-95 in. -lbs. ). 4) If the shock compresses more than 12mm, you need to increase the pre-load on the spring by turning the spring collar (C) clockwise. [. . . ] 5) Tune rebound (G) and compression damping (H) to personal tastes(see Shock Basics and Terminology). 6) If you have difficulty with set-up, please see your Authorized Giant Dealer. Drawing #14 20 Maintenance (See Drawing #15): Before every ride, it is important that you inspect the frame pivots and links for any looseness or play. 1) 2) 3) 4) 5) If there is play, make sure that the pivot bolts are tightened to the appropriate torque value (see below). If the pivot bolt is not tightened to the apporpriate torque value, unthread the bolt enough to expose the receiving threads on frameset or linkage. [. . . ]
