However, if you do work with any of these materials, it is extremely important to clean the tool using compressed air.
LUBRICATION
All of the bearings in this tool are lubricated with a sufficient amount of high grade lubricant for the life of the unit under normal operating conditions. Therefore, no further lubrica- tion is required.
