The linear rails are supplied with a protective oil coating on them. It is strongly recommended to prepare your work surface with paper towels and to wear disposable gloves.

Paper Towels

Linear Rail

With the rail still on the absorbent paper towels, carefully and slowly move the carriage from one end of the rail to the other

Small changes in resistance are normal, but the carriage becoming very hard to push, or binding completely are not

If the carriage does not move smoothly, or binds completely, refer to the Linear Rail Troubleshooting Guide

The linear rail carriages are not interchangeable. Do not try to use a carriage on a different linear rail than the one it was supplied with.
