3.5. Preparing the air (for machine with air motor)
Connect the machine to a correctly prepared air supply of sufficient purity using
a hose with the internal diameter of at least 12 mm
(0.5’’). The air installation must be
equipped with an air preparation unit: 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 whose ignition temperature exceeds 260
°C (500°F). If the machine is to
be left idle for at least 24 hours, 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
Once the machine is connected to a proper supply, set the maximum torque using
the
torque
adjusting
dial
and
select
gear
I
using the gear switch (only for machine with
electric motor). To start the operation, press the ON/OFF lever (air machine) or hold
the
ON
switch
(electric
machine).
To
lock
the
switch
in
position
ON,
press
the
ON
switch
lock first.
Spread
the
coolant
on
the
working
edge.
Then,
bring
the tool bit(s) close to the pipe
by rotating the spoke handles to the right. If the pipe face is not perpendicular to the
pipe axis, the tool bit will machine only a small segment of the pipe during initial
rotations. Thus, the feed rate should be chosen low until the tool bit is contacting the
pipe continually during at least one rotation.
The
axial
feed
is
0.11
mm (0.004’’) per
graduation (Fig. 6) or 2
mm (0.08’’) per one complete turn of the spoke handles. The
machine with electric motor allows toggling the speed between gear I and II after
stopping the rotation, and adjusting the rotational speed.
