should be moved towards the tube to start the threading
process by pressing on the head so that the threading
process begins.
As soon as threading has begun, the head should be
constantly and abundantly lubricated with threading oil
Super Ego (Fig. 2).
Once the appropiate threading length has been achieved
(the tube of the threading head should never overhang
in a normal thread), stop the motor (Fig. 3). Change the
position of the reverse gear lever and start the motor. The
machine will begin to unscrew the head and the tube will
become free (Fig. 4).
DANGER!
• Once the threading process has ended,
wait until the motor and the threading
head have stopped completely before
reversing the direction of rotation.
Maintenance
Cable and plug. Both the cable and plug should be in
optimum condition. Check them at regular
ON switch. Check that the machine switch unblocks
automatically when finger pressure is released. of any
anomaly, replace immediately with a new one.
Brushes. Check frequently for brush wear and perfect
contact with rotor. Change brushes when their length is
1/3 of original length. Use original Super Ego brushes.
In order to change the brushes make sure the machine
is disconnected from the mains supply. Open the back
brush-change lid, disconnect the brush-housing's
electrical connection, unmount the brush housing and
change the brush using original Super Ego replacement
brushes
Motor and rotor. The carbon dust accumulated in the
motor and brush housing should be removed 100 hours.
The motor's rotor should be permanently clean with an
uniform surface (light bronze colour).
Threading heads. Check that there are no damaged
teeth on the head to be used, as thread quality be
seriously deterriorated. Keep clean of swarf to achieve
top quality threading and longer life.
Gear box. Change grease every 500 operating hours.
After dismounting the machine, oil all mechanisms to
eliminate old grease. Remove parts with dry compressed
air and apply new grease with clean hands. Do not
use any dissolvents. Approximately 300 gr. of grease is
needed for a correct lubrication. An excessive amount
Operating / Service
of grease is not recommended as it can increase the
temperature of the machine. Grease type:
LGMT2 by SKF or similar. We recommend that this
operation be carried out by an authorized after-sales
service.
Tube fastener (clamp). Check that the tube fastener
clamp is in good condition. Replace when tube
displacement occurs.
Troubleshooting
Insufficient power
- Make sure that extension cable is not too long or that
it does not have insufficient section.
- Make sure that the right working speed is being used.
- Tube clamp must be well secured (bolt parallel to tube).
- Check operating condition of threading heads.
- Apply plenty and continuous lubrication to threading
heads.
- Make sure that the tube can be screwed.
Off-centre threading
- Check position of tube fastener (shaft parallel to tube).
- Check condition and quality of tube.
Insufficient thread lenght
- Check correct positioning of tube fastener.
- Make sure that there is no obstruction between the
machine and the tube fastener.
Poor thread quality
- Check condition of teeth.
- Check that there is continuous and abundant
lubrication.
- Check quality of tube.
- Check quality of threading oil (use Super Ego oil).
Incorrect adjustment of threading head
- Use the adapter for appropriate sizes (up to 1.1/4").
- Check that the appropriate threading head is being
used (Super Ego, serie 600 or equivalent).
