Something You Need to Know
Clean linear rails
•Lubricating oil!
•Tissue or cotton swobs!
Action
After the rails being cut, some dirt and
particles will stay on the surface, so
linear block won’t move smoothly.!
Wipe those dirt out with lubricating oil
and tissue before assembly, and always
keep the rail oily to prevent from rusting.

Pay more attention to the
grooves.

Something You Need to Know
Make sure you build it
right in each step
Errors will accumulate along with each
step in your assembly progress. To get a
solid machine you must build it correctly.!
Each page in this manual is written in a
similar structure. You can ignore if you
already know how to do, but you must
read the “Exam” step to ensure you do it
correctly.
