Laser Maintenance Schedule (Continued)
Mirror #2:
This mirror is located directly at the end of the gantry rail on the left-hand side and should be cleaned at least
every two months. Use the same directions for cleaning as you would Mirror #3
Mirror #1:
This mirror is located directly at the end of the laser tube on the left-hand side, this mirror should be cleaned
at-least every three months. Use the same directions for cleaning as you would Mirror #3
Laser Tube Output Coupler Lens:
This lens is located inside the output end of the laser tube, located closest to Mirror #3 and should be cleaned
at least every 3 months. You must be very careful when cleaning this lens, it CANNOT be removed from the
laser tube or replaced. As with other lenses and mirrors, use cotton swabs and isopropyl alcohol or lens wipes
with an alcohol-free solution to clean this lens. The goal when cleaning this lens is to remove dust, film
contamination from humidity, smoke or fumes. Be very careful, do not scratch the lens, it is non-replaceable
unless the whole tube is replaced.
Gantry Rails and Worm Rods:
The gantry rails and worm rods should be checked at least every 3-6 months. The time between the cleaning
and re-greasing of the gantry will depend on environment, usage of machine, cleanliness of area, etc. Your
gantry and worm rods should be re-greased with White Lithium Grease, as needed. If the grease on your
gantry or worm rods is discolored, clumping or filled with debris, it must be cleaned.
Linear Rails:
The linear rails are the guiding rails along the left and right sides and across the gantry. These rails should be
kept clean and without rust and have alight coating of white lithium grease. The linear rails should be cleaned
and examined once a month to prevent the laser head from seizing up. The surface of the rails should always
have white lithium grease on them and should be “wet” to the touch but not saturated or dripping.
The best way to see if you need to do some cleaning of the rails is to check the end of the rail where the
home switch is located. If you see a dirty line, then clean the rails off and apply a fresh coat of white lithium
grease.
Linear Bearings:
The linear bearings are found under the gantry (to mount the gantry to the side rails) and under the focal
head (to mount the focal head to the gantry). We recommend using white lithium grease and applying that
onto the linear rails and inside the linear bearings.
Incline Portion of Table & Collection Tray(s):
It is HIGHLY RECCOMENDED that these areas be cleaned of debris before, between and after operating the
machine. Doing so will help prevent any accidental hazards that may cause afire or excessive smoke.
Nuts/Bolts:
If you are concerned about these items rusting, then you should apply a thin coating of silicone base grease.
One application per year should suffice.
Rubber Belts:
The rubber belts should be checked for appropriate tension at least every 6months. You should expect the
two side belts to be the same tension and should be adjusted and tensioned on the same maintenance
schedule. These side belts work together to move the gantry from front to back. If one belts tensioned more
often than the other, that belt could become stretched out more than the other. It is difficult to describe the
appropriate tension of the belt but, there should be no slack, sagging or flapping. If the belt appears to be
worn on one side, it would be best to check the bearing alignment and assure that there is no damage. There
