Instructions for ALS-SA

This Air Lube System requires a ¼ I.D. diameter airline to the ball valve with dry air from an air dryer. Any moisture in the air can damage the Lube System and Davenport machine. It may be necessary to provide a coalescing filter if the air dryer does not prove to be efficient enough. (Call Nowak for pricing on current filter used)

The minimum supplied Air Pressure is 80 P.S.I.
2-4 cubic feet per minute of shop air is required to run the Air Lube System.

TO START THE MACHINE IN THE MORNING (COLD STARTING)
If the machine has been shutoff with the disconnect. Do not turn machine on until the following instructions in steps 1 and 2 have been completed.

1) Check the gage on the fill cap to make sure there is no air pressure in the tank.
Unscrew the cap and fill the tank with MOBIL DTE-26, SHELL TELLAS 68, or
TEXACO RANDO 68
2) Screw the cap back on and make sure the manual air valve is turned on.
The ALS automatically pre-lubricates all five revolving head spindles and all
shafts.
3) Turn the electrical control selector switch to jog. Push the green buttons in & out. This should turn on the Air Lube System. The horn and light will sound for a second or so and should go off. If horn and light doesn't, do not run the machine to manufacture parts. If horn and light does go off, check the four Bijur pressure gages that should read according to their tags. The 80 lb. Gage should stay on for about 20 seconds and shut off for 20 minutes. The ALS automatically pre-lubricates all five revolving head spindles and all shafts.
4) If the horn and strobe light stay on you will need to check the following things:

1. Low Air pressure below 80 lbs. (Check gage on top of fill cap)
2. Low oil in one of the tank chambers or all chambers
3. The filters are plugged, Check the 12-15 PSI Gage to see if there is pressure.
4. If the filters are plugged please call NOWAK PODUCTS 1-800-423-0970
5. We have an Exchange Program for the Air Lube Box. If you are using the wrong oil we can discuss the correct oil to stop the filter problems. Once these filters plug up they cannot be cleaned. They must be replaced. The Air Lube System filters are the same micron as the Bijur restrictor's porous metal filters. The Air Lube System will save the machine Bijur lube system from contaminants, but all restrictors need to be checked to make sure lube oils are getting to the correct locations.
6. On certian control systems The Air Lube has a unique feature that allows it to use less oil than the standard Bijur system. If the machine is not run for about five minutes the Lube System shuts down. When you restart the machine it automatically starts the Lube System.

NOTE:
This system described is the basic Air Lube System. Some have more features than others. Always call Nowak Products if you are having any problems with the systems. The Air Lube System can also be adapted to almost any machine tool or machining centers that require this type of lube system.
Call NOWAK PRODUCTS for more details. 1-800-423-0970
