3.4. Clamping the machine into the pipe
Insert the assembled machine into the pipe (1, Fig. 5) so that the tool bit(s) is placed
at the distance of at least 3 mm (0.12’’) from the pipe end. Then, expand the jaw
blocks to the inside diameter of the pipe by rotating the draw nut 2to the right with
the 13 mm socket wrench. The jaw blocks must be installed beyond the end
preparation location 3.

3.5. Preparing the air (for machine with air motor)
Connect the machine to a correctly prepared air source of sufficient purity by using
a hose with the internal diameter of at least 12 mm (0.5’’). The air source must be
equipped with an air preparation unit: filter, regulator, and lubricator (FRL). To achieve
full power of the air motor, all internal diameters of the air source must be at least
10 mm (0.4’’).
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 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, press the ON/OFF lever to start.
For the machine with an electric motor, set the gear 1 and, in cordless motor, the
maximum torque, and then press and hold the ON/OFF switch. To lock the switch in
the position ON (not available in cordless), press the ON switch lock before releasing
the ON/OFF switch. To adjust the speed, use a dial or, in cordless motor, change the
extent to which the ON/OFF switch is pressed.
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 slow 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.

Continue machining by rotating the spoke handles to the right. Use adequate feed
rate to establish a continuous chip cut. If the feed rate is too slow, only light stringer
chips will be removed, while too fast feed will make machining difficult and the chip
will start to have a rough or torn appearance. Never allow the tool bit to burnish the
surface. If chatter problems occur, reduce the feed rate and speed, and make sure
the type of tool bits corresponds to the material and the tool bits are sharp. Stainless
steel, which work hardens, must be worked with a fast enough feed, 0.08–0.15 mm
(0.003–0.006’’) per rotation, to stay under the work hardened surface.
If the machine with electric motor becomes overloaded, the motor will be shut off
automatically. However, prevent the motor from overloading and, if possible, machine
hardmaterials with not too fast feed rate and rotational speed.
After the pipe end is machined completely, discontinue rotating the spoke handles
and allow several more turns to improve the finish of the surface. Then, turn off the
motor by using the ON/OFF lever/switch, and wait until the rotation stops. Separate
the tool bit(s) from the pipe end to at least 3 mm (0.12’’) by rotating the spoke handles
to the left. Finally, loosen the draw nut with the 13 mm socket wrench to release the
clamping, and then remove the machine from the pipe. Use petroleum ether to clean
the pipe from excess coolant.
Clean the machine with a cotton cloth without using any agents.

3.7. Troubleshooting the electric motor
The machine with electric motor has aLED for troubleshooting. The LED permanently
lit means that the machine power is limited to prevent the motor from overheating as
a result of continuous overloading for extended periods.
Rapid flashing means that the safety circuit prevents the machine from starting
automatically when electrical power is restored after a power failure. To start the
machine is such a case, switch the motor off and on again.
Slow flashing means that the carbon brushes are almost completely worn, which
results in the motor shutting off automatically. The brushes must be replaced with
new ones by the manufacturer of the electric motor.
3.8. Troubleshooting the cordless electric motor
The machine with cordless electric motor has aprotection system that automatically
shuts off the motor when it is continuously overloaded for extended periods. To stop
the beeping signal that sounds in such a case, release the ON/OFF switch. If the
motor or battery feels very warm, wait until it cools before proceeding.
The motor can also shut off automatically if the machine jams in the workpiece.
To continue operation, release the ON/OFF switch and press it again. Avoid repeated
jamming in the workpiece.
Flashing of the LED means that the battery is almost completely discharged.
To see the charge level, press the LED activation button and check the LED. If the
battery is discharged completely, charge the battery or replace to a fully charged.
