WARNING WARNING
Only transport the machine when the gear/motor unit has been fi xed on the
vice side. The machine can otherwise tip over on the motor side. Make sure
that the machine is tied securely to the lifting mast of the forklift truck during
transport.
The machine must be installed so that long bars can also be clamped. There
must be enough room for the emerging workpiece on the motor side according
to the maximum thread length (hollow shaft up to Ø 30 mm) (only applies for
REMS Unimat 75). It is recommended to fasten the machine to the fl oor with
suitable bolts.
2.2. Electrical Connections
WARNING WARNING
Mains voltage present! Before connecting the machine, check whether the
voltage given on the rating plate corresponds to the mains voltage.
The machine can be connected to mains with or without a neutral conductor
(N). The control voltage is generated by a built-in transformer in the terminal
box. Open the and close the terminal box (Fig. 5 (43)) with the key. The machine
is delivered with a 16 A CEE plug which must be plugged into an appropriate
socket. If the machine is connected directly to mains (without a plug device),
a main switch must be installed. However, a protective earth conductor (PE)
must be available in any case.
The machine complies with protection class I.
WARNING WARNING
The direction of rotation must be checked before installing the universal auto-
matic die head (Fig. 2) on the hollow spindle (Fig. 11 (41)) when connecting
the machine. The changeover switch (Fig. 3 (5)) must be in position „2" for right
hand threads for this. The direction of rotation must correspond to the direction
arrow (Fig. 11 (42)) on the hollow spindle (41). The direction of rotation must
be changed by changing the phase (reversal of the electric conductors) by an
electrician if necessary.
A coil thermostat switches off the electric motor if the machine is overloaded.
The machine can be restarted after a few minutes whereby a lower speed must
be selected.
2.3. Thread cutting materials
Safety data sheets see www.rems.de → Downloads → Safety data sheets.
Only use REMS thread cutting materials. They ensure perfect cutting results,
long life of the chase dies and considerably relieve stress on the machine.
NOTICE NOTICE
REMS Spezial: High-alloy mineral oil-based thread-cutting material. For all
materials: steel, stainless steel, non-ferrous metals, plastics. Can be washed
out with water, tested by experts. Mineral oil-based thread cutting materials are
not approved for drinking water pipes in different countries, e.g. Germany,
Austria and Switzerland. Mineral oil-free REMS Sanitol must be used in this
case. Observe the national regulations.

2.4. Material support
NOTICE NOTICE
Longer pipes and bars must be supported by the height-adjustable REMS
Herkules 3B, REMS Herkules XL 12" (accessory, Art. No. 120120, 120125).
These have steel balls for easy movement of the pipes and bars in all directions
without the material support tipping over. Two REMS Herkules are an advantage
for frequent processing of long pipes or bars.
3. Setting the thread type and size
3.1. Mounting / changing the universal automatic die head
To avoid having to change the die set (chaser dies and holders) in the universal
automatic die head, interchangeable die heads with mounted die sets and
closing levers are recommended. Here, the complete universal automatic die
head is changed instead of the die set in the universal automatic die head so
that the tooling time can be reduced considerably.
The tube for the thread cutting material (Fig. 4 (28)) must be turned to the side
before applying the universal automatic die head. To do this, loosen the fi llister
head screw (Fig. 11 (30)) and turn the tube. When mounting the universal auto-
matic die head, make sure that the contact surfaces of the universal automatic
die head and the contact surface for holding the universal automatic die head on
12
the hollow spindle (41) are cleaned carefully. To apply the universal automatic
die head to the contact surface of the hollow spindle, it is an advantage if the
driver holder (41) is positioned on the hollow spindle to face upwards. The
driver (29) of the closing lever (1) which protrudes over the rear of the universal
automatic die head must be inserted into the mating piece in the hollow spindle
in a certain position when mounting the die head. Make sure that the closing
pin (39) which closes the universal automatic die head when moving back is
at the same height as the mark (40). The handle of the closing lever (1) must
stand radially when applying the universal automatic die head and must be
turned to the left or right if necessary, until the driver engages the closing lever.
Tighten the 3 screws (Fig. 6 (6)) of the universal automatic die head with the
pin wrench (Fig. 5 (7)). Position the tube for the thread cutting material (Fig.
4 (28)) so that the chaser dies are cooled/lubricated during the thread cutting
process.
The closing pin (Fig. 11 (39)) must be at the same height as the mark (40)
before removing the universal automatic die head from the machine. Remove
the 3 screws (Fig. 6 (6)) of the universal automatic die head with the pin wrench
(Fig. 5 (7)) and remove the universal automatic die head from the contact
surface to the front.
3.2. Mounting (changing) the closing lever
The following closing levers, with the appropriate different designations, are
required depending on the type of thread:
R for right hand tapered pipe thread (ISO 7-1, EN 10226, DIN 2999, BSPT,
NPT)
R-L for left hand tapered pipe thread (ISO 7-1, EN 10226, DIN 2999, BSPT,
NPT)
G for right hand parallel pipe thread (ISO 228-1, DIN 259, BSPP, NPSM, Pg,
Fg, BSCE, M × 1,5 (IEC))
G-L for left hand parallel pipe thread (ISO 228-1, DIN 259, BSPP, NPSM)
M for right hand metric bolt thread (ISO 261, DIN 13), UN-thread (UNC,
UNF), BS-thread (BSW, BSF)
M-L for left hand metric bolt thread ((ISO 261, DIN 13), UN-thread (UNC, UNF),
BS-thread (BSW, BSF)
The respective closing lever can only be changed in a certain position.
Mounting/changing the closing lever with the universal automatic die head
mounted on the machine:
Before changing the closing lever, it must be turned so that the closing pin (Fig.
11 (39)) is at the same height as the mark (Fig. 11 (40)). Now unscrew the
fi llister head screws (Fig. 2 (8)), remove the cover (Fig. 2 (4)) and unscrew the
locking screw (Fig. 11 (36)) with a screwdriver. Mount/change the closing lever.
Mounting/changing the closing lever with the universal automatic die head
removed from the machine:
Unscrew the fi llister head screws (Fig. 2 (8)), remove the cover (Fig. 2 (4)) and
unscrew the locking screw (Fig. 11 (36)) with a screwdriver. If the universal
automatic die head with the closing lever at the top is seen as a clock, the
closing lever can be changed at approx. 7 o'clock for a cylindrical right hand
thread and at approx. 9 o'clock for a tapered right hand thread (approx. 5 o'clock
accordingly for cylindrical left hand thread and approx. 3 o'clock for tapered left
hand thread).
Closing lever for left hand thread: Closing lever for left hand thread:
For right hand threads (as-delivered state) the stop screw (3) is mounted to the
left of the closing lever (1) when looking onto the universal automatic die head
from above (Fig. 2). For left hand threads the cover (4) must be turned over
and the stop screw (3) moved, i.e. the stop screw (3) must be mounted on the
right of the closing lever (1).
NOTICE NOTICE
An incorrectly mounted stop screw (Fig. 2 (3)) will be sheared off when
it hits the trigger cams (Fig. 11 (2))! The die head must be in the end position
to check the direction of rotation. To do this, turn the start cutting lever (Fig. 4
(17)) clockwise to the stop. Note position of the changeover switch (Fig. 3 (5)):
position 2 = right hand thread, position 1 = left hand thread.
The machine will be damaged if the wrong closing lever is used or the
stop screw is mounted incorrectly!
3.3. Mounting (changing) the die set
It is an advantage to remove the universal automatic die head and place it on
a bench to change the die set (chaser dies and holders) as described in 3.1.
Then remove the two cover screws (Fig. 2 (8)) with the pin wrench (Fig. 5 (7)),
remove the cover (Fig. 2 (4)), open the holder with closing lever and lever out
the holder no. 3 with a screwdriver as shown in Fig. 6. Remove the other holders.
Clean the holder, cover and square bar of the universal automatic die
head thoroughly.
Insert the new die set. Insert holder no. 1 in position 1, holder no. 2 in position
2, holder no. 4 in position 4 and holder no. 3 in position 3 of the die head. The
last holder must fi t easily and exactly without using tools, e.g. a hammer. If
there is too much play, e.g. due to a worn holder, increase the thread tolerances.
If there is no play, i.e. the holders jam, the closing lever can no longer open
and close the die head.
NOTICE NOTICE
This leads to breaking of the closing lever.
