INITIAL INSTALLATION INSTRUCTIONS

1. This machine requires a 1/4 inch diameter air line with dry air from an air dryer. Any moisture in the air can damage the lube system.

2. It may be necessary to provide a coalescing filter if the air dryer does not prove to be efficient enough. (Call Nowak for currently used filter & pricing)

3. Minimum Air Pressure 80 P.S. I. 2-4 Cubic Feet Per Minute Required We used an infrared thermometer Raytek Model ST2 (provided). The distance from the bronze spindle bearing to the nose of the Sensor was approximately 8 inches. Moving the infrared thermometer closer or further away will change the temperature readings. Using the infrared thermometer will allow the operator to determine how rapidly the spindle speed of the machine can be picked up to the max RPM required for the job. We would like to caution you that the spindle break in period of an air lube machine is longer. Initially monitor spindle temperatures and if dramatic increase in a spindle temperature occurs stop the machine and immediately notify Nowak Products Inc. Please be careful because once the damage is done it is difficult to repair.

4. Turn on the disconnect switch on the outside of the main electrical panel. Please wait approximately one minute for the air lube system to come up to pressure, and air bubbles start to show around the front of the Revolving Head Boss (O.D.) To turn off the machine at the end of the day the disconnect must be turned off to shut down the air lube system, or it will pump itself dry of oil.

START UP INSTRUCTIONS FOR ALS-SA & (Optional) CSDP-SA

To start the machine in the morning (Cold Starting)

1. Fill the oil tank with Mobil DTE 26- 20 Weight Oil. ( SHELL Tellus 68 or TEXACO Rando 68)

2. Note: The disconnect switch must be used to shutoff the Air Lube System as well as the Cycle Select Drive. The stop button will not shut off the machine as before.

3. Set cycle select switch to 45 cycle. Run machine for approximately 1 hour, or until machine gets to running temperature. Parts can be made on the machine while it is warming up. 110-120F degrees at 85 degrees room temperature.

4. Use the infrared thermometer Raytek Model RT2. Point the Sensor at the bronze spindle bearings as the machine idexes. Keep the Sensor consistantly 8 inches away. Moving the infrared thermometer closer or further away will change the temperature readings dramatically.

5. Turn the cycle select switch to the correct numbers of cycles for the job.

6. Run the machine, continually checking the spindle temperature to make sure they do not overheat.

7. To refill the air lube tank the machine must be stopped. The tanks cannot be filled while the machine is running. Shutoff the air to the machine by the ball valve. Gently start to open the top of the fill spout (right hand thread). You may feel air rushing past your fingers. Allow the the tank to completely release all the air before filling the tank. Repeat Step # 1.

8. Replace the fill cap do not over tighten  O-ring seal.

9. Turn ball valve back on.

10. Machine is ready to run.

The same instructions apply to a machine with a standard main drive motor configuration.
