How do I change the weight setting on the Weider 8630?

Insert a Weight Pin (93) under the desired Weight (90), pushing it in until the bent end touches the weights, then turn the bent end downward. The weight setting can be changed from 6.5 pounds to 106.5 pounds in increments of 12.5 pounds. Note that due to cables and pulleys, the actual resistance at each station may vary from the weight setting — refer to the Weight Resistance Chart on page 24. (Page 22)
