Maintenance and service procedures of the laser beam optics assembly (cleaning and maintenance of
the lens and mirror) are to be conducted only by personnel who are familiar with laser safety and
with the potential laser hazards from the product.
Turn off the laser and close the shutter during lens and mirror cleaning, as operation of the laser
without the lens or mirror installed can result in a potential laser hazard from the invisible output
beam, even at distances of hundreds of feet away from the system.
Daily
1. Check for any frayed wires or leaking water lines.
2. Motion of table and laser should not interfere with any objects.
3. Keep vacuum table hoses suspended so they do not catch on edge of the system or any other
objects. This may cause motion of the table to be irregular.
4. Verify that air is coming from the nozzle. If not, turn on the air compressor and turn up the air
pressure to desired level.
5. Clean system after each days use. This includes wiping dust and debris from Teflon coated lead
screw with a clean, dry, soft cloth. DO NOT clean Teflon coated lead screw with any chemical as
this will cause flaking of the Teflon coating. Clean any dust and debris from the rest of the
system including power supplies and any other components.
6. Replace paper table covering as needed with thin paper. Newspaper roll remnants work well for
this.
7. Shut off power to the laser system each day.
Weekly
After starting the laser system, check the water level in the chiller unit (100 watt and above). Make
sure all chiller filters are free of dust and debris.
Note: Refer to maintenance section of your chiller manual for complete description of your chillers
maintenance schedule. Also, refer to your laser manual for additional information on required coolant
additive and mixture ratio.
Remove the 1” aluminum honeycomb and the 1” aluminum Ecolite from the vacuum table top. Clean
the top honeycomb, Ecolite and bottom of the vacuum table with degreaser to remove any debris or
water material buildup. If there is any waste material debris stuck in the honeycomb or Ecolite, use a
portable vacuum cleaner to clean it.
Monthly
Top Gantry Rails
Use a good grade of 10W30 automotive oil to lubricate
the bearings on the rails once very month. This may be
required more often with heavy use of the laser system.
Wipe rails with a clean, dry cloth before lubricating the
bearings.
The laser must be positioned so that the hole at the front
of the gantry allow access to the oil point. See the photo to
right for a example of this. Use the special tip
of the oil can (provided) to insert the oil Zerk on the
bearing block. Pump the can several times.
