Installation
Installation of the automatic lubricator is as simple and straight forward as attaching the unit to the power and air supply. Clean shop air is a necessity.In shops where the track roller assembly area is very close to the idler assembly area, the automatic lubricator can be placed between the two areas and the control pendent can be used in either location without moving the unit. However, for shops frequently servicing track chain, rollers, and idlers at the same time, it is not recommended that the machine be shared between the two areas. Since the track area uses 30W oil and the roller/idler area uses 80W-90 EP oil, frequent oil changes would be required throughout the day. The automatic lubricator contains an electrical surge/spike suppressor to eliminate the effects of power fluctuations resulting from surrounding shop equipment usage.Prior to usage, complete the following start-up procedure to make sure that the unit is operating properly:Initial Setup
1. Fill the oil container approximately three-fourths full with SAE 30W oil (track roller and idlers) or 80W-90 Extreme Pressure gear oil (track chain).2. Connect the unit to electrical and air supply. The unit is equipped with a quick disconnect fitting for the air supply on the back of the unit.Vacuum Cycle Check
1. Set the fill switch to OFF and the vacuum switch to VACUUM.2. Prevent air flow through the probe tip by plugging the end of the probe with a finger. Closing off the probe tip during the entire vacuum cycle simulates the probe tip inserted into a properly assembled roller or idler.3. While keeping the probe tip plugged, press the START button on the control pendent as shown in Illustration 14. The sound of evacuated air from the vacuum generator indicates that the vacuum cycle has started.
Illustration 14. Check the vacuum by closing off the end of the probe tip.4. Check the vacuum pressure gauge to verify a vacuum is being generated. When the gauge needle reads approximately 22 in.Hg, the sound of evacuating air will stop. This indicates that the 20 second vacuum check period has started. Remember to keep a finger tightly over the probe tip until the entire vacuum cycle and check is completed.5. If no appreciable loss of vacuum occurs during this 20 second period, the green "Cycle Complete" light located on the pendent will turn ON. This diagnostic light tells the operator that a proper vacuum has been generated and no leaks are present.6. If the red "Cycle Failure" light is ON, refer to the "Troubleshooting" instructions located in this manual.Fill Cycle Check
1. Set the fill switch to FILL and the vacuum switch to OFF.2. Obtain a clean, metered, container large enough to hold 1000 cc (mL) of oil.3. Set the fill volume to 1000 cc using the thumb dials located on the control panel.4. Place the probe tip inside the container and press the START button located on the control pendent to begin pumping oil. If the oil flow is significantly
