Place the hose end detached from the tool holder inside the coolant tray to
ensure that oil can circulate. In the case of machines supplied from November
1999 onwards, a hole is provided in the coolant tray into which the hose end
can be inserted. If required, this hole can be drilled with a 14 mm bit. It is harm-
less if the electric pump runs empty, i.e. when the coolant tray is emptied.
Ensure without fail that the machine is horizontal when on a mobile stand (by
removing wheels or placing the two stand pipes underneath).
Slide the roll grooving unit onto the guide arms (8) until the drive shaft of the
roll grooving unit is projecting with its 3 faces into the quick-action hammer
chuck. With the REMS Tornado, close the chuck by operating the pedal switch.
With the REMS Gigant, close the clamping jaws using the chuck key until the
clamping jaws are in contact with the 3 faces of the drive shaft. Position and
bolt the hydraulic hand pump (10).
2.6. Material support
CAUTION
Even when in short lengths, pipes must be supported using the
height-adjustable REMS Herkules or other suitable material supports depending
on their diameter (and weight!), in order to ensure that the machine does not
tip forward.
3. Operation
3.1. Tools
Three sets of grooving rollers are needed for the full working range. Each set
of grooving rollers comprises the upper pressure roller (11) and the low coun-
terpressure roller (13). Grooving rollers Cu (pressure roller (11), counterpressure
roller (13)) for copper tubes 54 –159 mm.
Changing the grooving rollers
Operate the drive machine in inching mode using the pedal switch (4) until the
securing bolt of the counterpressure roller (13) is pointing downwards. Undo
the securing bolt and pull out the counterpressure roller (13). Turn the pressure
roller (11) until the mark on the stub shaft (12) is pointing down wards. Undo
the securing bolt and slowly pull out the stub shaft (12). Remove the pressure
roller from underneath.
CAUTION
Before pulling out the stub shaft (12), place your hand under-
neath the pressure roller (11) – otherwise it will fall onto the floor!
Insert the selected pressure roller from underneath and slide in the stub shaft
(12). The mark on the latter must be pointing downwards. Tighten the securing
bolt of the pressure roller in the direction of the shaft mark. Insert the selected
counterpressure roller. Note the position of the drive dog (flat edge) on the rear
end of the counterpressure roller. Tighten the securing bolt.
3.2. Working 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 some 50 mm from the pipe end.
Clean any dirt and scale off the inside and outside of the pipe ends.
Close the pressure limiting valve (16). Place the pipe on the counterpressure
roller and press it against the machine. Align the pipe axis-pa rallel, supporting
it as necessary. Operate the feed lever (15) of the hydraulic hand pump several
times and feed the pressure roller (11) forward until it is up against the pipe.
Set the stop for the groove depth (17); to do so, turn the setting disc for 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 be moved downwards. Operate
the machine at top speed. Switch on the machine using the pedal switch (4),
operate the feed lever (15) several times, and slowly slide the pressure roller
(11) into the pipe while the machine is running until the stop plate is touching
the housing (pressure on feed lever increases). Keep the machine running a
few more turns without feed. Then shut down the machine, open the pressure
limiting valve (16), remove the pipe, and check the groove made. To do so, use
the diameter measuring tape or the slide rule at a 90° angle. If necessary, adjust
the stop (17) and repeat the procedure. 1 scale graduation on the stop plate
corresponds to an infeed of approx. 0.4 mm, a complete revolution is 1.5 mm.
3.3. Support of the material
CAUTION
Pipes and long pipe sections must be supported. Ensure here
that the support keeps the pipe at righ
4. Maintenance
WARNING
Pull out the mains plug before maintenance and repair
work! This work may only be performed by qualified personnel.
4.1. Servicing
Lubricate the roll grooving unit at the lubricating nipple (19) every 40 working
hours. Use REMS transmission grease, article no. 091012.
4.2. Inspection/maintenance
See also the instructions for use of the respective drive machine REMS Tornado,
REMS Gigant, REMS Magnum.
Check the hydraulic oil level regularly. To do so, unscrew the hydraulic hand
pump and hold it with its rear end vertically upward. Open the pressure limiting
valve (16), unscrew the oil dipstick (20) in the lid of the container, and check
the oil level. If necessary, top up with REMS hydraulic oil, article no. 091026.
Always heed the marks on the oil dipstick – do not pour in too much oil.
Change the hydraulic oil completely at last every 12 months. To do so, tilt the
container to drain off the old oil, which must be disposed of without harming
the environment.

6. Action in Case of Trouble
See also the instructions for use of the respective drive machine REMS Tornado,
REMS Gigant, REMS Magnum.
6.1. Trouble: Incorrect groove dimensions (width or depth).
Cause: ● Incorrect grooving rollers.
● Worn grooving rollers.
● Incorrect feed space selected with setting disc.
6.2. Trouble: Machine does not start.
Cause: ● Emergency-stop not reset.
● Motor protection switch has responded.
● Worn or damaged carbon brushes.
6.3. Trouble: No grooving roller feed.
Cause: ● Pressure limiting valve not closed.
● Too little hydraulic oil in system, system leakage.
● Feed cylinder defective.
6.4. Trouble: Pipe not gripped.
Cause: ● Grooving rollers worn.
● Chuck of drive machine not closed.
● Too little hydraulic oil in system, system leakage.
6.5. Trouble: Pipe runs out of the grooving rollers.
Cause: ● Pipe not aligned axis-parallel with the machine.
● Grooving rollers worn or defective.
