3-3. Lubrication
Install an oiler between the compressor and the tool.
Use the machine oil ISO VG-10. Failure to lubricate
as required may result in damage to the tool. Use of
oil that is too thick will reduce the performance of the
tool.
3-4. Short hose fittings
Do not fix a coupling directly on the tool. Make sure
that after a short hose is fixed with the Hose Nipple
R3/8X3/8 including in the accessories, then the
coupling be attached. If the coupling is directly fixed,
it would be damaged by the vibration and the life
would be shortened.

4-2. Operation
You do not have to press the Needles against the
workpiece with much force. Keep the Needle in
contact with the work surface and apply force as
if you were just trying to maintain solid contact
between the Needles and workpiece. Too much
force, if applied, could result in damage to the
Needles, such as bending and / or breakage,
or even damage to the tool itself. The Needles
will closely follow any kind of configurations the
workpjece surfaces may have, making it possible to
get the work done with ease, speed and accuracy.
