Periodically apply 1 or 2 drops of air tool oil to throttle lever and safety lever pivots, and work lever to distribute the oil. Storage Avoid storing the cut-off tool 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.
