Mechanical Booster Oil Change - Mazak STX SC L PLUS CONTROL Training Manual

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.
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.
CAUTION: DO NOT OVER-FILL
