This regulator should be set at the green marker ( 1.0 Kg/cm2 )
Laser System Pressure ( Torr value )
A> The LED display for the system pressure is located in the upper "LASER CONTROL
UNIT" cabinet.
STX SC 1.5 Kw = 54 torr
2.0 Kw = 50 torr

8
Mechanical Booster Oil
A> The mechanical booster is located in the bottom cabinet of the "LASER CONTROL
UNIT". The oil level sight glass is located on the side of the mechanical booster. A
window is located on the side of the "LASER CONTROL UNIT" to view the sight glass.
B> The oil level should be between the two red lines on the sight glass when the booster is
off.
C> The oil must be changed:
STX SC - Every 2000 hrs. or 1 year ( whichever comes first )
-
Or if the color of the oil becomes dark.
-
OIL TYPE: OR-7000
Vacuum Pump Oil
A> The vacuum pump is located in the bottom cabinet of the "LASER CONTROL UNIT". The
sight glass for the pump is located on the front face of the pump.
B> The oil level should be between the two marks on the sight glass.
NOTE: Older models may not have a mark on the sight glass, fill to center of glass.
C> The oil must be changed:
- After the first 750 hours of operation.
- Then every 1500 hrs. or 1 year thereafter ( whichever comes first )
- OR if the color of the oil becomes dark.
Oil type: OHE-270
D> See pg. 20 of this manual or your maintenance manual for the oil change procedure.

9
Chiller Unit
A> The chiller reservoir must be filled with distilled water, a corrosion inhibitor and a
fungicide. A level gauge is located on the side of the chiller unit to indicate the fluid
level. The reservoir holds approx. 40 gal.
Recommended corrosion inhibitor: "ISOGUARD" ( 1/2 gal. / 50 gal. of water )
Recommended bactericide/fungicide: "GAX - 26" ( 5 oz. / 50 gal. of water )
B>The air pressure gauge must be set at 5.0 Kg/cm2 by adjusting the air out regulator.
C> The water pressure must be set at 3.5 Kg/cm2 by adjusting the water bypass
valve.
Water bypass valve location: Below water pressure gauge.
D> The chiller temperature must be 17.5 degrees Celsius + or - 1 degree.
E> The chiller unit must be flushed every 6 months if the recommended corrosion inhibitor and
fungicide are used. (See pg. 22 for flushing procedure )
NOTE: If the recommended corrosion inhibitor and fungicide are not used, the flushing
interval is every 3 months.
Recommended flushing agent: “CITRANOX” ( 1 gal. / 50 gal. Of water )
F> The chiller heat exchangers must be kept clean by vacuuming or blowing out with
compressed air. DO NOT place additional filters over the heat exchangers. This will reduce the
air
flow and cause the compressor to work much harder to maintain the proper temperature.
G> The air entering the chiller must be very clean and dry before it enters the chiller air filter
system. These filters are not meant to be the primary dryer system for the air supply.
The chiller air filters need to be checked every 1000 hours and replaced as necessary.
Lubrication
A>Lubrication of the chip conveyor chain must be performed once per month. (Light
machine oil)
B>The centralized automatic lubrication system requires oil as needed. (Alarm occurs
when low) It will lubricate the ball screws and LM guides for all axes.
STX SC: (Mobil Vactra Oil No. 2)

Focus Lens
The focus lens should be cleaned once per week if the majority of materials cut are mild and stainless
steel. If a large percentage of work is aluminum or non-metallic material, the lens may need to be cleaned
daily.
Vacuum Pump and Mechanical Booster Maintenance
Vacuum Pump Oil Change
1 > Run the vacuum pump for at least 10 min. so the oil is warm and will drain easily.
2 > Turn "Laser Power" OFF and turn off / lock out the main breaker.
3 > Remove the fill cap on the top of the pump.
4 > Remove the drain plug at the end of the oil drain line by unscrewing the two (2) brass fittings at the
end of the hose. Do not remove the lead cap which is epoxied to the fitting.
5 > Open the oil drain valve and empty the oil into a receptacle. Elevate the rear of the pump to insure
that the entire content is drained.
6 > Close the oil drain valve and replace the drain plug.
7 > Add the new oil to the fill port at the top of the pump. The oil level must be between the two marks
on the sight glass.
NOTE: recommended oil:
- OHE-270 (LEYBOLD)
8 > Replace the fill port plug.
9 > Turn "Laser Power" ON and run the pump for at least 15 min.
10 > Turn "Laser Power" OFF. Check that there are no leaks from the oil drain plug or the demister
filter. Confirm the oil level is between the two marks on the sight glass. If the oil has become dark
in color, drain the oil and replace with new oil by repeating steps 3 through 9.
Vacuum Pump Demister Filter
1 > Remove the demister filter by unscrewing the hex nut on the front face of the pump.
2 > If the filter is contaminated with oil, replace the filter. Clean the rubber seal on the new filter and
wet with oil before replacing.
NOTE: Filter must be flush against the back wall of the housing.
DO NOT run the vacuum pump without the demister filter installed.
3 > After the pump has been run for 15 min., check that there is no leakage from the filter port. If
smoke/oil mist is emitted from the exhaust (below cabinet), the filter is not mounted properly.

11
Mechanical Booster Oil Change
1 > Run the booster for at least 10 min. so that the oil is warm and will drain easily.
2 > Turn off "Laser Power" and turn off / lock out main breaker.
3 > Open the "Air Admit plug " and leave off for at least 20 minutes. This plug is located in the lower
cabinet of the "Laser Control Unit" and is on the end of a short hose near the solenoid block.
NOTE: If the "Air Admit Plug" is not removed for the specified period before opening any ports on the
booster, oil may be pulled into the resonator and contaminate the internal optics.
4 > After at least 20 minutes has passed replace the air admit plug.
5 > Remove the oil fill cap located on the top of the booster, above the sight glass.
6 > Remove the oil drain plug located at the end of the oil drain line and empty the oil into a receptacle
(Separate the drain plug between the two brass fittings; Do not remove the cap).
7 > Replace the oil drain plug.
8 > Pour the new oil into the oil fill port until the oil level is between the two red lines on
the face of the sight glass.
NOTE: The oil level will slowly drop as the new oil works its way down into the drain line. Add oil until
the level stays between the red lines for at least 10 min.
CAUTION: DO NOT OVER-FILL
STX SC: Oil Type OR-7000
9 > Replace the Oil fill port plug. There must not be any leakage from the plug or the laser gas will
become contaminated by air.
10 > Cycle "Laser Power" ON and OFF at least 4 times before turning on "Laser High Volt". This will
purge the air which entered the resonator when the "air admit" plug was removed.
11 > Turn on "Laser Power" and run the booster for at least 15 min.
12 > Turn off "Laser Power" and check for leakage at the oil drain plug. ( If air bubbles are present at
the drain plug, tighten the plug to eliminate ). Check the oil level after the booster has been off for at least 5
min.
13 > If the oil has become dark in color, drain the oil and replace with new oil by
repeating steps 3 through 13.

Chiller Unit Maintenance
4-1 Chiller Flushing Procedure
1 > Drain the contents of the chiller by attaching a hose to the drain port and opening
the valve.
2 > Fill the chiller reservoir with tap water and the appropriate amount of flushing agent.
Recommended Flush Agent: "CITRANOX" ( 1 gal. per 50 gal. of water )
3 > Run the chiller for 8 - 12 hours. The machine can be in operation while flushing.
4 > Drain the contents of the chiller.
5 > Fill the chiller reservoir with tap water only.
6 > Run the chiller for at least one half hour.
7 > Repeat steps 4 - 6 at least 3 times to purge the system of all the flushing agent.
8 > Fill the chiller reservoir with distilled water and the appropriate amount of corrosion
inhibitor and bactericide/fungicide.
Recommended corrosion inhibitor: "ISOGUARD" ( 1/2 gal. per 50 gal. of water )
Recommended Bactericide/Fungicide: "GAX - 26" ( 5 oz. per 50 gal. of water )
4-2 Heat Exchanger cleaning
1 > The heat exchangers must be cleaned regularly. The interval for cleaning the heat
exchangers is typically every 2-3 days depending on the environment.
2 > The exchangers can be either vacuumed or blown out with compressed air so that
there is no dirt collected on the cooling fins.
NOTE: DO NOT place filters over the heat exchanger air intake. Filters block the
volume of air flow causing the chiller to work harder and can potentially damage
the compressor.
4-3 Replacing the Mist Filter Element
1 > Remove the front cover on the chiller unit.
2 > Locate the filter housing. Remove the bottom portion of the filter unit.
3 > Turn the filter element until it is removed.
4 > Attach the new element.
5 > Replace the filter housing.

13
Lubrication of Axes and Chip Conveyor
Axis Lubrication
The STX SC model has an automatic lubrication system which supplies oil to all axes automatically during
operation. When the quantity of oil in the reservoir reaches its lower limit, an alarm will occur and operation will be
stopped until the level is brought within the acceptable range.
See your MAZAK OPERATING AND MAINTENANCE manual for details about adding oil and cleaning the
oil return pipe.
Lubrication of the Chip Conveyor
For all models the chip conveyor must be lubricated once per month by the following method.
1 > Turn on the chip conveyor.
2 > Clean the hinge links with a wire brush.
3 > Manually lubricate the hinge links side chain and main shaft bearing by applying machine oil.
Cleaning the Focus Lens
Removing the Focus Lens
1 > Disconnect the assist gas quick-disconnect fitting.
2 > Unscrew the torch retaining ring and remove the torch head assembly.
3 > Using the custom lens tool, remove the lens mount retaining ring.
4 > Measure the depth that the lens mount is screwed into the torch assembly with a caliper and make
note of the value.
5 > Remove the lens mount using the custom lens tool.
6 > Remove the lens retaining ring from the lens mount taking care not to drop the contents of the
holder.
7 > Place a rigid piece of material over the end of the mount from which the retaining ring was
accessed. Turn the material and the mount upside down and set on the work table.
8 > Carefully lift the lens mount upward leaving the contents resting on the table in a stack.
9 > Remove the two copper spacers from each side of the lens taking care not to damage the indium
wire gasket on the inner surfaces of the copper rings. If any of the indium gasket remains on the
lens, carefully peel off the material without making contact with the surface of the lens.
10 > Place the lens on several sheets of dry/clean lens paper.

14
CAUTION: Use the following precautions when handling optical components:
1 > NEVER touch the surface of the optic or allow it to make contact with any object other than
cleaning materials.
2 > NEVER wash optics with water, soap, alcohol or water/alcohol based cleaning solutions.
3 > NEVER store optics in locations subject to extreme temperature variances or high humidity.
4 > NEVER subject optics to a dirty environment or cleaning materials which may be contaminated by
foreign matter.
5 > NEVER use optics which have surface damage such as cracks or de-lamination of coatings.
6 > NEVER apply excessive force to optics or optical mounts during handling.
7 > ALWAYS wear the proper, clean clothing including finger cots or latex gloves.
8 > ALWAYS wash your hands after handling a focus lens.
See your MAZAK OPERATING AND MAINTENANCE manual for further information.
Optic cleaning procedure
1 > Lay the optic on several sheets of clean/dry lens paper.
2 > Place a single sheet of lens paper over the optic. Be careful to only touch one edge of the paper so
that the oil from your skin is not absorbed and transmitted to the optic.
3 > Dispense a few drops of Methanol onto the surface of the optic until the total surface is covered
and the lens paper adheres.
4 > Slowly pull the lens paper across the optic taking care not to also drag the optic.
5 > When the lens paper has absorbed all of the methanol, remove the paper and discard.
6 > Repeat steps 2 through 5 until the surface is clean.
7 > If the surface contamination can not be removed using lens paper, place a few drops of Methanol
on a cotton ball and lightly wipe the surface in one direction.
DO NOT wipe the surface in a circular fashion ( particles embedded in the coating may break free
and scratch the surface ). Follow up with the lens paper procedure.
NOTE: DO NOT blow on the optic with your breath to remove particles on the surface.
Use the supplied blow bulb to remove any foreign matter.

6-3 Installing the Focus Lens
1 > Clean the lens mount with Methanol and a clean dry cloth.
2 > Stack the lens components in the proper configuration:
The curved surface of the focus lens faces up; the beam hits the curved surface first.
3 > Set the lens mount over the components and screw the retaining ring until snug.
Back off the retaining ring slightly to allow room for expansion due to heat. The wave
washer will allow the components to expand without damage to the focus lens.
Dry air filter (Machine)
There is a filter element in the purge air (yellow) line located in the cabinet where the assist gas
ports are located. This element acts as a filter and moisture indicator. When the element turns
pink, there is water in the air line. If this occurs, check the air system for contaminated filters.

STX/SC: PROCEDURE TO CLEAR MAINTENANCE ALARMS
The super charged series machines have an alarm list of maintenance items which will automatically appear after
2000 hrs. of operation. These alarms are not sensing a fault within the system, but rather acting as a reminder to
perform certain maintenance tasks. In some cases the interval at which the alarms are displayed may be sooner than
the item actually requires. When a maintenance item occurs, call Mazak with the current hour reading and confirm
whether or not the alarm merits attention. The procedure below will reset maintenance alarms.
1> Turn off laser power, high voltage and power at the operating panel.
2> Turn on the power at the operating panel.
3> Press any key once, to clear the maintenance alarm.
4> Press the second blank menu key from the right. ( do not "HOME" or press any other keys).
5> Press "input"
6> Press the blue "D" (DISPLAY) key.
7> Press the "parameter" menu key.
8> Press the "NC" menu key.
9> Press the "next page" menu key until parameter no. 5111 is present.
10> Cursor to parameter 5111
11> Press the "ADJ" menu key.
12> Enter the current value for 5111 + 2000
Example: if 5111 = 2000
then enter 4000
13> Press "INPUT"
14> The alarm will now occur after the next 2000 hours has elapsed.

Safety notes for set-up procedure
1. During the following procedures the laser is emitted from the torch. Since the operator is required to
view the reflected beam at a close proximity, plastic safety glasses are mandatory.
2. Confirmation of the laser discharge in a ready state can be determined by the "cw" or "pulse" led on
the operating panel. If either of these led's are illuminated, the laser will be emitted when the "shutter
unit" is in its open state.
3. When "reset" is pressed any laser conditions which were input are canceled, which can be confirmed
by viewing the "CW" and "pulse" LED's, which are not illuminated when the laser conditions are
canceled.
4. The laser shutter unit can only be opened "MANUALLY" if the "HANDLE" or "JOG" mode have
been highlighted/activated.
5. Confirmation of the shutter unit in the open state can be determined by the illumination of the yellow
"shutter open" button located next to the manual shutter key switch or the red flashing light above the
electrical unit cabinet.
Caution: do not place any part of your body beneath the nozzle when the shutter unit is in the open
state. Always confirm that the shutter unit closes after manually opening the shutter with the key
switch.
Notes For Set-Up Procedure
1. The set-up procedure must be performed in case of the following:
> The torch is removed
> The entire nozzle assembly is removed
> The nozzle to focus relationship must be changed
2. Once the set-up procedure has been performed, the focus and nozzle gap will be the same for any thickness of
material unless a manual or programmed override is used ( ie. G87p__ ).
3. When performing the following procedures, various menu keys must be pressed to activate the particular mode
required. When a menu key is pressed it will become highlighted which indicates that the function is activated.
4. When the machine is turned off and then back on, it will retain the set-up. During the course of operation it may be
necessary to adjust specific portions of the set-up procedure without repeating the entire procedure. Such
adjustments include changing nozzle tips due to contact with material and re-calibrating the profiler due to wear of
the stylus plate.
5. The standard focus is designed to meet the application needs of a wide range of materials and thickness’. If your
application is limited to one type of material or if there are very long runs of one material, it may be advantageous to
set up for a focus most suitable for that material.

19
