Festool Cleaning and Lubricating Oil ensures that these parts continue to operate efficiently. First, the oil removes residue so that deposits and buildup won't gum the system. Secondly, the oil lubricates moving parts to reduce wear on gears, pistons and rotors. Thirdly, oil helps protect internal components from residual moisture that can accumulate and potentially corrode metal parts. Adding this oil is a simple procedure that will help maintain optimal operating performance of compressed air tools.
