To begin the procedure of cleaning and greasing the bearing rails, shut off the laser and remove the power cord from the machine.
Clean the Bearing Rails
Manually position the lens assembly to one side.
Apply rubbing alcohol to a cotton swab.
Clean one end of the bearing rail by running the cotton swab along the top and bottom of the rail. Repeat this process until the cotton swab comes away clean, using new cotton swabs when the old ones become dirty.
Move the lens assembly along the x-axis toward the end of the bearing rail you just cleaned.
Apply rubbing alcohol to another cotton swab.
On the remaining, uncleaned portion of the bearing rail, run the cotton swab along the top and bottom of the rail, repeating until the cotton swabs come away clean.
Grease the Bearing Rails
Next, apply a small amount of bearing grease to one spot on the top and bottom of the bearing rail.
Slowly move the lens assembly left and right along the length of the bearing rail at least several times to spread the grease evenly across the assembly’s path.
Be sure to wipe away any excess grease that builds up at either end of the rail. Excess lubricant can more easily attract debris and cause premature wear when it works its way into the bearings.
Plug the machine in and turn it on.
