3.5. Preparing the air (for machine with air motor)
Connect the machine to a correctly prepared air source of sufficient purity. All inner
diameters of the air source (including the supply hose and fittings) must be at least
12
mm (0.5’’). The
air
source
must
be
equipped with an air preparation unit that
contains a filter, regulator, and lubricator (FRL).
Maintain the FRL unit as required to keep the water trap drained, filter cleaned,
and the lubricator oil reservoir filled so that there is a drop of oil every 2
–5 seconds.
Use only oil which ignition temperature is more than 260°C (500°F). If the machine is
to be left idle for at least 24 hours after the work is finished, increase the delivery of oil
and run the motor for 2
–3 seconds, which will prevent rusting and degrading of the
rotor vanes.
3.6. Operating
After the machine is connected to a proper supply, use the torque adjusting dial to
set the maximum torque. In electric motor, use the gear switch to select gear I.
To start, press the ON/OFF lever (air motor) or press and hold the ON switch (electric
motor). To lock the switch in the position ON, press the ON switch lock before using
the switch.
Spread
the
coolant
on
the
working
edge.
Then, rotate the handles to the right to
bring
the tool bits close to the pipe. If the pipe end is not perpendicular to the pipe
axis, the tool bit will machine only a small pipe segment during initial rotations. Thus,
use a low feed rate until the tool bit is contacting the pipe continually during at least
one rotation.
The
feed
is
0.11
mm (0.004’’) per graduation (Fig. 6) or 2 mm (0.08’’)
per one full turn of the handles. The machine with electric motor allows changing the
gears between I and II after the rotation stops, and adjusting the rotational speed.
