Remove the tool set. Make sure that the machine is horizontal.
Push the roller grooving unit on the guide arms (8) until the drive shaft of the
roll grooving unit protrudes into the hammer chuck with its 3 faces. Close the
chuck by actuating the foot switch so that the clamping jaws are in contact with
the 3 faces of the drive shaft.
See REMS Tornado instruction manual: Swing in he pipe cutter and the inner
pipe deburrer. Undo the wing screw on the clamping ring, remove the cuttings
tray. Detach the hose end from the tool holder and insert in the hole in the
coolant tray so that lubricant can circulate inside the pump to prevent it from
being damaged. Remove the tool set. Always ensure that the machine is always
positioned horizontally on the mobile base frame. Remove wheels or place the
two stand pipes underneath.
Push the roller grooving unit on the guide arms (8) until the drive shaft of the
roll grooving unit protrudes into the hammer chuck with its 3 faces. Close the
chuck by actuating the foot switch so that the clamping jaws are in contact with
the 3 faces of the drive shaft.

See REMS Amigo, REMS Amigo 2, REMS Amigo 2 Compact instruction manual:
Fix REMS roller groove device to a workbench or base frame (accessory, Art.
No. 849315). Fix the support (21) with the 2 enclosed cylinder-head screws M
8 × 25 to the side face of the REMS roller groove device. Push the electric die
stock wi h inserted adapter (22) on the drive shaft onto the roller groove device
as far as it goes. The motor (23) must be between the teeth of the support (21).
Fasten the lock washer (24) with cylinder-head screw M 8 × 16 (25) to the drive
shaft of the roller groove device. Set the direc ion of rotation ring of the die
stock to "R".
Always support pipes and longer pipe sections wi h a height-adjustable mate-
rial rest, REMS Herkules 3B (accessory Art. No. 120120). Make sure that the
material rest guides or supports the pipe axis-parallel to the roller groove
machine.

3. Operation

Three sets of grooving rollers are required for the whole working range of steel
and stainless steel pipes. Only one set of Cu grooving rollers is required for
the working range of the copper pipes. Each set comprises the upper pressure
roller (11) and the lower counterpressure roller (13).
Operate the drive unit REMS Collum RG, REMS Collum RG 2, REMS Collum
RG 2 Compact with safety inching switch (27) or drive unit REMS Magnum RG
with foot switch (4) in inching mode un il the securing bolt of the counterpres-
sure roller (13) is facing downwards. Undo the securing bolt and remove the
counterpressure roller (13). Turn the pressure roller (11) until the marking on
the stub shaft (12) is facing downwards. Undo the securing bolt, pull out the
stub shaft (12) slowly, remove the pressure roller downwards.
Hold one hand underneath the pressure roller (11) before pulling out the stub
Re-insert the selected pressure roller from the bottom and push in the stub
shaft. The marking on the stub shaft (12) must face downwards. Tighten the
securing bolt of the pressure roller in the direction of he marking on the shaft.
Insert the selected counterpressure roller, note the position of the drive dog
bolt.
3.2. Work procedure
Pipe ends must be cut off at right angles. Welds or welding residues (beads)
in the pipe must be sanded off over a length of approx. 50 mm from the end of
the pipe. Clean any dirt and scale from the inside and outside of the pipe ends.
Close the pressure limiting valve (16). Place the pipe on the counterpressure
roller and press against the machine. Align the pipe axis-parallel, support wi h
REMS Herkules 3B (accessory, Art No. 120120) if necessary. Actuate the feed
lever (15) of the hydraulic hand pump several times and feed the pressure roller
(11) forward until it is touching the pipe. Set the stop for groove depth (17). To
do this, turn the setting disc for the groove depth (18) to a stage corresponding
to the pipe size between the housing and the stop plate and move the stop
inwards until it is up against the setting disc. Secure the stop plate using a
locking nut. Turn the setting disc back to the engagement position so that the
stop plate can move downwards. Operate all drive units respectively with the
highest speed. Switch on the drive unit with the safety inching switch (27) or
foot switch (4). Actuate the feed lever (15) several times and feed the pressure
roller slowly into the pipe with the drive unit running until the stop plate touches
the housing. Let the machine continue running a few revolutions without feeding.
Shut down the machine, open the pressure limiting valve (16), remove the pipe
and check the groove made. Use the diameter measuring tape or slide rule at
a 90° angle to do this. Adjust the stop (17) and repeat the procedure if neces-
sary. 1 scale graduation on the stop plate corresponds to an infeed of approx.
0.4 mm, a whole revolution 1.5 mm.
Always support pipes and longer pipe sections with a height-adjustable mate-
rial rest, REMS Herkules 3B (accessory Art. No. 120120). Make sure that the
material rest guides or supports the pipe axis-parallel to the roller groove
machine.

4. Maintenance

4.1. Maintenance
WARNING
manual of the respective drive unit REMS Amigo, REMS Amigo 2, REMS Amigo
2 Compact, REMS Tornado, REMS Magnum.
Clean the REMS roller groove device regularly especially when it has not been
in use for a long time. Clean plastic parts (e.g. housing) only with REMS CleanM
machine cleaner (Art. No. 140119) or a mild soap and a damp cloth. Do not
use household cleaners. These often contain chemicals which can damage
the plastic parts. Never use petrol, turpentine, thinner or similar products for
cleaning. Lubricate the REMS roller groove device every 40 operating hours
at the lubrica ing nipple (19). Use REMS gear grease Art. No. 091012.
Check the hydraulic oil level regularly. To do so, unscrew the hydraulic hand
pump and hold with the rear end facing vertically upwards. Open the pressure
limiting valve (16), unscrew the oil dipstick (20) from the lid of the tank, check

Amigo 2, REMS Amigo 2 Compact, REMS Tornado, REMS Magnum.
Change the hydraulic oil completely at least every 12 months. Tip up the tank
to drain off the old oil. Dispose of oil oil according to regulations.
