the supply of compressed air must be
disconnected or shut off.
When disposing of components,
lubricants, etc … ensure that the
relevant safety procedures are carried
out.
For dust extraction, please contact your
local sales.
The tool is designed for a working
pressure of 6.3 bar (90 psig). The
compressed air must be clean. The
installation of a lter is recommended.
For maximum efciency and
performance, comply with the
specication of the air hose (antistatic
hose). (Refer to gure no.1 for
compressed air connection).

To obtain maximum efciency from the
pneumatic tool, preserve its features
and avoid repeated repairs, a routine
inspection and repair programme
are recommended at least every 500
hours, the intervals between the various
inspections depending on the amount of
exertion on the power tool.
Check the free speed of the tool
at regular intervals and after each
operation or maintenance task. Remove
the abrasive to check the speed. The
maximum allowed speed shown on
the tool must not be exceeded and the
vibration level must not be excessive.
This tool is tted with blades which can
operate without lubricated air. However,
a small amount of oil allows the tool to
provide full power and lengthens its life.
The use of dry air with no trace of oil
may reduce the life of blades.
