disc. Bolt thread must always be set to „Bolt". Clamp the adjusting disc with
the clamping lever, close the die head by pressing the closing and opening
lever (10, Tornado / 14, Magnum) down slightly to the right. The die head opens
either automatically (with tapered pipe threads), or at any time manually by
slight pressure to the left on the closing and opening lever.
If the holding power of the clamping lever (11, Tornado / 15, Magnum) is insuf-
ficient (e.g. through blunt dies) when the 2½ – 3" and the 2½ – 4" die head is in
use, due to the increased cutting force applied, with the result that the die head
opens under cutting pressure, the capscrew on the side opposite the clamping
lever (11, Tornado / 15, Magnum) must also be tightened.
The pipe cutter (15, Tornado / 18, Magnum) cuts pipes ¼ – 2", resp. 2½ – 4".
The reamer (16, Tornado / 19, Magnum) deburs pipes ¼ – 2" resp. 2½ – 4". To
avoid rotation, latch the reamer sleeve into the reamer arm either in the front
or in the back end, depending on the position of the pipe.
3.2. Chuck
A size adjusted clamping sleeve (Art.-No. 343001) is required for sizes < 8 mm
when operating with Magnum up to 2" and Tornado, for Magnum up to 4" <
20 mm. When ordering the clamping sleeve the required clamping size needs
to be provided.
3.2.1. Chuck Tornado (19) and (20)
The self-clamping jaws open and close automatically through left or right turning
of the switch (18) and operating the foot switch (21). Pay attention when changing
rear and front clamping jaws that the particular clamping jaws are fitted in
corresponding to fig. 4 and 5, as otherwise damage will arise. On no account
switch on the machine until all clamping jaws and both clamping jaw covers
have been fitted.
3.2.2. Chuck Magnum (1) (2)
Quick action hammer chuck (1), guide chuck (2)
The front quick action hammer chuck (1) with the large clamping ring and the
movable chuck jaws installed in the chuck jaw carriers ensures secure, concen-
tric clamping with the minimum of force. As soon as the material juts out of the
guide chuck (2), it should be closed.
Changing the chuck jaws Magnum
With the clamping ring (22), close the chuck jaws (24) to a clamping diameter
of approx. 30 mm. Remove screws of chuck jaws (24). Slide chuck jaws out
towards the rear by using an appropriate tool (screw driver). Slide new chuck
jaws into the chuck jaw carrier from the front.
3.3. Operation
Remove blockages of chips and fragments of the workpiece before starting
work.
3.3.1. Tornado
Swing out the tools and bring the tool holder to the right-hand end-position by
means of contact lever (5). Feed in the material so that it projects approx. 10
cm out of the chuck (19). Swing down and close the die head (8). Set switch
(18) to position 1, then operate footswitch (21); the material will now be clamped
automatically. On types 2010 and 2020, the second operating speed can be
selected for sectioning, debur ring and small thread cutting operations. To do this,
with the machine running, slowly move switch (18) from position 1 to position 2.
With the contact lever (5), advance the die head onto the rotating material.
After one or two threads have been cut, the die head will continue to cut auto-
matically. In the case of tapered pipe threads, the die head opens automatically
when the standard length of thread is reached. When cutting extended threads
or bolt threads, open the die head manually, with the machine running. Release
foot switch (21). Set switch (18) to R. Depress foot switch (21) briefly to release
the material.
Threads of unlimited length can be cut by reclamping the material, as follows.
When the tool holder approaches the machine housing during the thread cutting
process, release foot switch (21) but do not open the die head. Set switch (18)
to R. Release the material and bring the tool holder and material to the right-
hand end-position by means of the contact lever. Switch on the machine again
by setting the switch to position 1.
For pipe cutting operations, swing in the pipe cutter (15) and bring it to the
desired cutting position by means of the contact lever. The pipe is cut by rotating
the spindle clockwise.
The resulting inside burr after cutting will be deburred with the reamer (16).
To drain the thread cutting oil: Take off the hose of the tool holder (2) and hold
it into a container. Keep the machine running until the tray is empty. Or: take
off the tray and empty it using the pouring spout (17).
3.3.2. Magnum
Swing out the tools and move the tool carrier to the right-hand end position
with the aid of the pressing lever (8). Pass the material to be threaded through
the opened guide (2) and through the opened chuck (1) so that it extends by
about 10 cm from the chuck. Close the chuck until the jaw comes against the
material and then, after a short opening movement, jerk it shut once or twice
in order to clamp the material firmly. Closing the guide chuck (2) centers the
material that extends from the rear of the machine. Swing down and close the
die head. Set the switch (3) to position 1, then operate the foot switch (4).
Magnum 2000 / 3000 / 4000 is switched on and off with the foot switch (4) only.
On Magnum 2010 / 3010 / 4010 and 2020 / 3020 / 4020, the second operating
speed can be selected for sectioning, deburring and small thread cutting
operations. To do this, with the machine running, slowly move switch (3) from
position 1 to position 2. With the contact lever (8), advance the die head onto
the rotating material.
After one or two threads have been cut, the die head will continue to cut auto-
matically. In the case of tapered pipe threads, the die head opens automatically
when the standard length of thread is reached. When cutting extended threads
or bolt threads, open the die head manually, with the machine running. Release
pedal switch (4). Open quick action hammer chuck, take out material.
Threads of unlimited length can be cut by reclamping the material, as follows.
When the tool holder approaches the machine housing during the thread cutting
process, release pedal switch (4) but do not open the die head. Release the
material and bring the tool holder and material to the right-hand end-position
by means of the contact lever. Clamp material again, switch on machine again.
For pipe cutting operations, swing in the pipe cutter (18) and bring it to the
desired cutting position by means of the contact lever. The pipe is cut by rotating
the spindle clockwise.
Remove any burrs inside the pipe resulting from the cutting operation with the
pipe reamer (19).
To drain the cooling lubricant: Take off the flexible hose of the tool holder (7)
and hold it into a container. Keep the machine running until the oil tray is empty.
Or: Remove screw plug (25) and drain trough.
3.4. Production of nipples and double nipples
Use REMS Nippelfix (automatic internal clamping) or REMS Nippelspanner
(internal clamping) for threading nipples. Ensure that both sides of the pipe are
deburred inside. Always slide the pipe up to the end of the clamping section.
To clamp the piece of pipe (with or without thread) with the REMS Nip pelspanner,
use a screwdriver and turn the spindle to expand the head of the Nippelspanner.
Expand only with attached piece of pipe, otherwise damage will arise.
Do not cut nipples with REMS Nippelfix and REMS Nippelspanner shorter than
is permitted by the appropriate standard.
3.5. Producing left­handed threads
For left-handed threads only the REMS Magnums 2010, 2020, 4010 and 4020
are suitable. The die head in the tool set holder has to be off-set e.g. by using
a M 10 x 40 screw in order to cut left-handed threads, otherwise the lifting and
the start-cutting can be damaged. Set the switch to position "R". Change the
hose connections at the coolant pump or for shut of the coolant pump briefly.
Alternatively use a switch valve (Art.No. 342080, accessory), attached to the
machine. With the lever on the switch valve (Fig. 9) the direction of flow on the
coolant pump is reversed.
4. Maintenance
DANGER
Pull out the mains plug before maintenance and repair work! This work
may only be performed by qualified personnel.
4.1. Maintenance
The machine is maintenance free. The gearbox operates in a sealed-off oilbath
and therefore needs no lubrication.
4.2. Inspection / Servicing
The motor of the Tornado 2000 / Magnum 2000 / 3000 / 4000 is equipped with
carbon brushes. These wear out and therefore need checking from time to
time, and, if necessary, changing. Loosen by about 3 mm (⅛") the 4 screws of
the motor cap and remove both caps from the motor. See also point 6: Actions
in case of trouble.
5. Machine Wiring and Electrical Components
See next page.
