Laser Maintenance Schedule (Continued)
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 are many laser machine designs but, the method of changing the
belt tension should not be too complex. It is normally a method of tightening a screw and then applying a lock nut to
keep the screw in place.
Air Filters:
If a fume extractor was purchased with the machine, there will be filters installed within that fume extractor. These air
filters work best when air can move freely from one side to the other while catch dust, fumes and other debris within
the air. If the air filter is dirty the air pressure will be greatly reduced. The main application of a fume extractor is to
clean the air and absorb the dangerous smells and fumes that some material can produce. Some of these gases can be
caustic, nauseating, volatile, corrosive, or even deadly. It is best to use multiple stages of filters to catch the particles of
different sizes. New filters can be ordered from BossLaser by contacting sales.
Chiller & Coolant:
First, automotive antifreeze should NEVER be used as a laser coolant, only deionized water. In the absence of deionized
water, distilled water can be used (tap water being a last resort). The coolant should always be clean and clear. It Isa
common problem for the coolant to become infested withhold, this often will look like a murky green water with algae
build up on the inner walls of the hoses. This issue can be solved in just a few steps.
1.
Flush out the bad water from the chiller or the water pump reservoir.
2.
Create absolution of water and 20% bleach. Cycle the bleach-water solution for about 30 minutes then
flush out this water.
3.
Switch the inlet and outlet hoses and flush them with more cleaned distilled water. This should dislodge
mold from inside the laser tube.
4.
The safety flow senor could also be full of mold; the best solution is to take it apart and clean it with soft
brush or pipe cleaners. Make sure to re-assemble the sensor correctly and without leaks. It is possible that
harsh cleaners could creep into the sensor electronics and cause permanent damage.
✎Note: The chiller water should be changed AT LEAST once every two months.
