Installing Spring Clips Check that the spring clip is securely attached. Failure to install the spring clip or improper installation may result in an accident. 1) Spring clips are used to secure the connecting link of chain sizes smaller than RF2060 and RS60. Insert the pins of the connecting link into the bushes of the free inner links, place the link plate over the pin ends, and slide the spring clip over the ends of the pins so that the slot and the fingers of the clip engage the grooves securely (Figures 18 and 19). 2) Pay careful attention to ensure that the fingers of the spring clip are not spread too wide. If the spring clip does not fit securely, it could become detached without warning, leading to an accident (Figures 19 and 20). Figure 17: How to Connect Attachment Chain 3) In general, the spring clip should be installed in the direction opposite to chain travel, as shown in the drawing below (Figure 21). Figure 22: Open Legs of Cotter Pin Figure 21: Spring Clip Installation 3. Installing Cotter Pins Securely install the cotter pins in the holes provided on the ends of the pins. Failure to install the cotter pins or improper installation may result in an accident. 1) After the cotter pin has been fully inserted into the hole on the end of the pin, open the legs of the cotter pin to an angle of around 60° (Figure 22). Do not re-use cotter pins. Do not use commercially available cotter pins. 2) How to Open the Legs of the Cotter Pin (4) Insert the blade of the flathead screwdriver at an angle and move the screwdriver back and forth to open the legs of the cotter pin. (5) Press down the head of the cotter pin tightly so that the cotter pin will not disengage from the cotter pin hole. (6) Bend the cotter pin legs to the 60° angle mentioned above. Perform this operation with extreme care! If the end of the screwdriver slips, it could puncture the hand or cause other injury. (3) Insert the blade of a flathead screwdriver at the point where the legs of the cotter pin have opened slightly. (1) Insert the cotter pin into the cotter pin hole. (2) Use a pin that is somewhat larger in diameter than the cotter pin to lightly tap the head of the cotter pin. The legs of the pin will open slightly. 1. Assembling with a Connecting Link 1) Insert the pins of the connecting link into the bushes of the free inner links. Place the free link plate over the pin ends and secure using a spring clip or cotter pins. 2) The pins are slip-fit into the connecting plate, meaning the pins can be inserted manually.
