General safety instructions
Attention! When using electrical tools,
please observe the following basic safety
rules in order to reduce the risk of electric
shock, injury and fire.
Read and follow all of these instructions
before using the threading machine.
Wear adequate safety clothing:
Do not wear loose clothing or jewellry. They
could be caught by moving parts of the
machine. For outdoor work, rubber gloves and
nonskid shoes must be worn.
Work in a correct position.
Avoid working in a tiring position. Stand up
firmly and maintain a good balance at all times.
Keep your work area clear.
Do not allow other people to touch the
machine or cable. Keep children out of reach.
Keep your work area tidy.
An untidy and dirty work area can lead to
accidents. Do not leave electrical tools out in
the rain. They should not be used in a humid or
wet environment nor near inflammable liquids
or gases.
Do not overwork the machine.
Use the machine only for those jobs for which it
has been designed, do not force it. Stop the
machine if it is not working correctly.
Protect the power cable.
Before starting up the machine, check that the
electric cable and switch are in optimum
condition. Do not carry the machine by the
cable nor pull it to disconnect it from the plug.
Protect it from heat, oil and sharp edges.
Disconnecting the electric cable.
Before carrying out any maintenance work or
change of accessories, disconnect the machine
from the mains.
Keep your machine clean.
For safe operation, keep the machine and
threading heads free of swarf. Keep the
handles dry and free from oil and grease.
Protect your machine against blows and do not
leave it in dusty or muddy areas. At the end of
the day, lock it with its accessories in a dry
place, out of the reach of children.
Check the machine when idle.
Familiarize yourself with the machine’s
operation. Lubricate the machine before
executing any threading operation.
Working with a generator.
Check that there is a minimum output power
of 2.8 Kwa.
Attention!
The use of accessories other than those
indicated in the instuction manual could lead
risk of personal injury.
Preparation for start up
Q
Do not thread without using the tube clamp.
The tube clamp should be used even when
threading the smallest sizes.
W
Check that the tube clamp is perfectly
mounted.
If the tube is not fastened correctly, the
machine would rotate on the threading
head, with the consequent risk of injury to
the operator. The tube fastening bolt is left
loose inside the case cover and should be
screwed into its corresponding hole.
E
Check condition of ON switch.
When released of pressure, check that the
ON switch unblocks automatically.
R
Use of extension cables.
Check that the cable is as thick and as short
as possible. The extension cable should be
for more than 15 Amp and not longer than
30 metres.
T
Do not thread without abundant and
continuous lubrication.
Good lubrication will prolong the life of your
machine and threading heads. It will also
improve threading quality.
Y
Always thread at working speed.
Threading from right to left should be done
at the working speed indicated on the
reversing gear lever in the direction of the
arrow. Fast speed will only be used to
unscrew the threading head from the tube.
For left thread, insert the threading head at
the opposite end of the machine and
maintain rotation in work direction.
U Do not change speeds during the threading
operation.
When the threading operation has been
completed, stop the machine and change gears
to initiate reverse movement and free the tube.
Start up
Q
Before carrying out any operations with the
machine, first read the general safety
instructions and preparations for start up.
W
Fasten the tube clamp securely and check
that the machine’s anchor bolt is parallel to
the tube to be threaded. The bolt should
extend over the end of the tube by
approximately 1 or 1.5 cm.
E
Choose the threading head according to
your needs and mount it in the octagonal
coupling of the machine. Fit the adapter first,
when using a 1.1/4” head. For right thread,
insert the threading head ad the front of the
machine. For left thread, insert the threading
head at opposite end of the machine.
R When using the adapter, this should be
directly inserted in the octagonal coupling of
the machine on the same in which the
threading head has been inserted (right
thread: front side; left thread: opposite side)
and secured by its threaded cap.
T
To insert the head into the adapter, move
the mobile part of the latter counter-
clockwise until it is completely inserted. This
will spring back securing the head. To
remove it, proceed in likewise manner.
Y Next insert the machine in the tube and
make sure that it is securely guided into its
housing by the tube clamp bolt.
U
Check that the reverse gear lever is correctly
in place (arrow in working direction). Press
the electric switch with your right hand.
Rotation will start immediately. Now the
head should be moved towards the tube to
start the threading process by pressing on
the machine.
I
As soon as threading has begun, the head
should be constantly and abundantly
lubricated with threading oil Rothenberger.
O Once the appropiate threading length has
been achieved (the tube of the threading
head should never overhang in a normal
thread), stop the motor. 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.
ATTENTION!
Fast speed must only be used to unscrew
the head. Never thread on fast speed.
Care and maintenance
Before carrying out any job on the
machine, disconnect the plug from the
mains outlet.
Q Cable and plug.
Both the cable and plug should be in optimum
condition. Check them at regular intervals.
W
ON switch.
Check that the machine switch unblocks
automatically when finger pressure is
released. In case of any anomaly, replace
immediately with a new one.
E Brushes.
Check frequently for brush wear and perfect
contact with rotor. Change brushes when
their length is 1/3 of original length. Use
original Rothenberger brushes.
R Motor and rotor.
The carbon dust accumulated in the motor
and brush housing should be removed every
100 hours. The motor’s rotor should be
permanently clean with a uniform surface
(light bronze colour).
T
Threading heads.
Check that there are no damaged teeth on
the head to be used, as thread quality could
be seriously deteriorated. Keep clean of
swarf to achieve top quality threading and
longer life.
