3.5. Preparing the air (for machine with air motor)
Connect the machine to a correctly prepared air source of sufficient purity. Make sure
that all inner diameters of the air source (including the supply hose and fittings) are of
at least 10 mm (0.4
″). Make sure that the air
source has an air preparation unit that
contains a filter, regulator, and lubricator (FRL).
Maintain the FRL unit as required. 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 oil whose ignition temperature is more than 260°C (500°F). If you are not going
to use the machine for at least 24 hours, increase the supply of oil and let the motor
operate for 2
–3 seconds. This will prevent rusting and degrading of the rotor vanes.
3.6. Operating
After you connect the machine to the correct supply, press the ON/OFF lever to start.
In the electric motor, set the gear 1. In the battery motor, set the gear 1 and the
maximum torque. Then, press and hold the ON/OFF switch. To lock the switch in the
position ON (not available in the battery motor), press the ON switch lock before you
release the ON/OFF switch. To adjust the speed, use the dial or, in the battery motor,
change the force that you apply on the ON/OFF switch.
Apply 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 cut only a small part of the pipe during initial rotations. Thus, use
a low feed rate until the tool bit is in continuous contact with the pipe 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.
Fig. 6.

Rotate the handles to the right to continue machining. Use such a feed rate so
that the chip is continuous. If the feed rate is too low, only small chips are removed.
