Setup and Assembly 1. Rotate knurled collar until ball is aligned with hole in collar. Any missing parts or damage should be reported immediately to your JET® distributor. Do not use a damaged tool. Read this instruction manual thoroughly for operation, maintenance and safety instructions. 2. Insert needle shank into cylinder, aligning notch in shank with ball. 3. Rotate knurled collar 180-degrees in either direction to secure needle shank. Box contents: 4. Install spring, needles and flange.
Maintenance 5. Change filters on the air system on a regular basis. Lubrication 6. Air-line pressure may be increased accordingly to compensate for extra-long air hoses (usually over 25 feet). Inside diameter of hose should be minimum 3/8-inch. The needle scaler should be lubricated daily (or before each use) with air tool oil through the air inlet. During continual operation, it should be reoiled every 1 to 2 hours. This can be done with an in-line oiler, or manually.
Use anti-whip devices across hose couplings to prevent hose from whipping in the event of a hose failure or coupling disconnect. If greasing is required, use a grease that is highly water resistant for front case components on air impact wrenches, grinders and sanders. Always use moisture traps at the compressor for the main distribution line. Use moisture traps and in-line oilers on each downline that is to be used for air tools. (See Figure 2).
