Lubrication Requirements
Always install a line lubricator on the air line as
close to the tool as possible. A lter-regulator
lubricator unit (FRL) is strongly recommend-

recommended grade of oil and check that the oil
is reaching the tool. Running the tool without
lubrication is likely to cause damage to the
components causing premature replacement.
