Instructions
Inspect your trampoline for faulty parts and damage by having a friend or family member jump on your trampoline. Observe the compression in all the springs when the person bounces on the trampoline. Since the springs and mat provide the trampoline with its elasticity, springs that are too compressed can decrease the trampoline's bounciness.
Replace the damaged springs and tighten them to increase the tension of the trampoline. Refer to your trampoline's instruction manual on how to replace and tighten the springs. Make sure to keep all the springs at the same tension to avoid an imbalance in the weight distribution of the springs.
Observe the trampoline's padding and mats for rips and damage, and replace them if necessary. The mat and padding of the trampoline also help counter the weight of the person on the trampoline and forces him or her back up with the tension from the springs. If the padding and mat have damage, the elasticity effectiveness will also decrease.
