IMPORTANT: Connecting a quick-change coupling directly to the tool is not recommended, as vibration may cause the connection to fail. Instead, add a leader hose and install any quick-change couplings farther down the line. Setup and Assembly 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. 6. Hold grinder with a light but secure grip.
Storage Avoid storing the grinder in very humid locations which promotes rusting of internal mechanisms. Always oil the tool and disconnect air hose before storage. Air system requirements 1. Use proper air hose size (refer to tool specifications). The hose should be just long enough to serve the working area. Excessive hose length will cause pressure drop. 2. Make sure air compressor supplies clean, dry air at correct CFM for the grinder. 3. Set air pressure to 90 psi.
