    A typical air line layout is shown below. If an automatic in-line filter/regulator is used, it will keep the tool in good condition, but should be regularly checked and topped up with oil. CLARKE airline oil should be used and the lubricator adjusted to approx 2 drops per minute.

Ensure any moisture is drained from the compressor daily and the inlet filter is kept clean.
