ENG-7 Owner's Manual Model No. 875. f99340 Owner's Manual Model Exploded Lubrication Recommended An in-line filter-regulator-lubricator (fig 1) is recommended as it increases tool life and keeps the tool in sustained operation. The in-line lubricator should be regularly checked and filled with air tool oil. Proper adjustment of the in-line lubricator is performed by placing a sheet of paper next to the tools exhaust ports and holding the throttle open approximately 30 seconds. The lubricator is properly set when a light stain of oil collects on the paper. No. 875. f99340 View Drawing Lubricants Use air tool oil or any other high grade turbine oil containing moisture absorbent, rust inhibitors, metal wetting agents and an EP (extreme pressure) additive. See Figure 3 for location/air inlet. Excessive amounts of oil should be avoided. In the event that it becomes necessary to store the tool for an extended period of time (overnight, weekend, etc.), it should receive a generous amount of lubrication through the air inlet (Figure 3). The tool should be run for approximately 30 seconds to ensure oil has been evenly distributed throughout the tool. The tool should be stored in a clean and dry environment.

Be sure the hose is the proper size. Long hoses or tools using large volumes of air may require a hose with an I.D. of 1/2" or larger depending on the total length of the hose. 5b. Do not use multiple number of hoses connected together with quick connect fittings. This causes additional pressure drops and reduces the tool power. Directly connect the hoses together.

Locate the separator/filter as far as possible from the compressor. 2b. Install an air dryer. 2c. Anytime water enters the tool, the tool should be oiled immediately. ENG-10 ENG-11
