Installation Method

Taking the P509 computer chair as an example, when installing, you need to attach the five casters to the five-star base one by one. After installation, test the smoothness of the casters by moving them to ensure they can rotate normally without any stuttering or abnormal noises, thus ensuring the comfort and safety of using the office chair.

Replacement Steps

When you need to replace the office chair casters, the operation is not complicated. First, lay the chair down so that the side with the casters faces up for easy operation. Then, pull out the old casters in the opposite direction of the force core. Pay attention to applying an appropriate amount of force during the pulling process to avoid damaging other parts of the chair. When inserting the new casters, push them in along the direction of the holes to ensure they are firmly installed and can bear weight and rotate normally.
