2.4. Installing (changing) the expanding head (16) in REMS Akku-Ex-Press
P-CEF ACC and REMS Power-Ex-Press P-CEF ACC (Fig. 11)
Pull out the mains plug. Read and observe the installation and assembly
instructions of the manufacturer/supplier of the used system. Never use non-
matching expanding heads (system, size) for expansion work. The joint could
be unserviceable, and both the machine and the expanding heads might be
damaged. Grease the cone of the expanding mandrel (18) lightly. Screw the
selected expanding head as far as it will go onto the expander. Read and
observe the installation and assembly instructions of the manufacturer/supplier
of the used system. REMS P and Cu expanding heads are unsuitable for the
REMS Power-Ex-Press P-CEF ACC and may therefore not be used..
Changing the expanding device on the REMS Power-Ex-Press P-CEF ACC
Pull out the mains plug. Unscrew the expanding device (15) from the REMS
Power-Ex-Press P-CEF ACC. Screw on the selected expander as far as it will
go and tighten by hand.
2.5. Assembly (changing) of the expander (15), the expanding head (16) on
REMS Akku-Ex-Press 22 V ACC (Fig. 10)
Choose an expander (15) to match the expanding head (16). Use the expander
Cu for the REMS Cu expanding heads. Use the expander P for the REMS P
expanding heads. Use the P-CEF expander for the REMS expanding heads.
Only use system-specifi c expanding heads. REMS P and REMS P-CEFexpanding
heads are labelled with letters to identify the compression sleeve system and
a number to identify the size, REMS Cu expanding heads only with a number
to identify the size. Read and observe the installation and assembly instructions
of the manufacturer/supplier of the used system. Never expand with an unsuit-
able expander, unsuitable expanding heads (system, size). The joint could be
useless and the machine and expanding heads could be damaged. Grease
the cone of the expanding mandrel (18) lightly.
Changing the P and Cu expander
Screw the selected expanding head onto the expanding device (15) to the stop.
The expanding device must now be set so that the thrust of the drive machine
is taken up by the drive machine and not the expanding head at the end of the
expanding. Unscrew the expanding device (15) complete with screwed on
expanding head from the drive machine for this. Let the feed piston run forward
as far as possible without the machine switching into reverse. In this position
the expander with screwed-on expanding head must be screwed onto the drive
unit until the expanding jaws (17) of the expanding head (16) are fully open.
The expanding head must be secured with the locking nut (24) in this position.
NOTICE
Make sure that the compression sleeve is far enough away from the expanding
head (16) in the expanding process because otherwise the expanding jaws
(17) can bend or break.
Changing the P-CEF expander
Remove the battery. Screw on the locking nut (24) and the selected expander
(15) up to the stop. Screw the selected expanding head (16) onto the expander
up to the stop.
3. Operation
CAUTION CAUTION
After the drive unit has been in storage for a long period of time, the overpressure
valve must be actuated fi rst by pressing the reset button (13) before putting back
into operation. If it is stuck or stiff, it may not be pressed. The drive unit must be
handed over to an authorized REMS customer service workshop for inspection.
3.1. Radial presses (Figs. 1 to 9 and 17 to 21)
The pressing tongs, Mini pressing tongs, pressing ring, adapter tongs and Mini
adapter tongs, especially the pressing contour (11, 22) of the pressing jaws
(10) or all 3 pressing segments (21) must be checked for damage and wear
before every use. Damaged or worn pressing tongs, Mini pressing tongs,
pressing rings, adapter tongs and Mini adapter tongs may no longer be used.
There is otherwise a risk of incorrect pressing or accidents.
A trial pressing with inserted press fi tting must be made with the drive unit and
the respectively used pressing tongs, Mini pressing tongs and the respectively
used pressing ring with adapter tongs or Mini adapter tongs before every use.
The pressing tongs, Mini pressing tongs (1), the pressing ring (20) with adapter
tongs or Mini adapter tongs must fi t into the drive unit mechanically and be
properly lockable. After completing the pressing, check that the pressing jaws
(10) close fully at "A" for the pressing tongs, Mini pressing tongs (Fig. 1), the
(PR-3B) pressing ring (Fig. 20) and the 45° (PR-2B) pressing ring (Fig. 21).
After completing the pressing, check that the pressing jaws (10) close fully at
"A" and on the opposite side "B" for the (4G) pressing tongs (Fig. 17) and the
(S) pressing tongs (Fig. 18). After completing the pressing, check that the
pressing segments (21) close fully at "A" and on the opposite side "B" for the
(PR-3S) pressing ring (Fig. 19) and the XL (PR-3S) pressing ring. Check the
tightness of the connection (observe national specifi cations, standards, regula-
tions, etc.)
If during closing of the pressing tongs, pressing tongs Mini or pressing rings a
marked ridge is created on the compression sleeve, the pressing may be
defective or not tight (see 5. Trouble).
CAUTION CAUTION
For preventing damages make sure to avoid operating situations like
exemplarily shown in Fig. 14 through 16, that no distortion between
22
pressing tongs, pressing tongs Mini, pressing rings, adapter tongs, adapter
tongs Mini, fi tting and drive unit occurs. Failure to do so could lead to
fracture and fl ying parts can cause serious injuries.
3.1.1. W 3.1.1. Working procedure 3.1.1. Working procedure
Press the pressing tongs, pressing tongs Mini (1) together manually until they
can be pushed over the press fi tting. Always position the drive unit with the
pressing tongs on the press fi tting at right angles to the pipe axis. Release the
pressing tongs so that they close around the press fi tting. Hold the drive unit
by the housing grip (6) and the pistol grip (9).
Place the pressing ring (20) around the pressing fi tting. Insert the adapter tongs/
Mini adapter tongs (19) into the drive unit and lock the tong retainer bolt, posi-
tion the rotary sleeve (27) if necessary, see 2.2. Insert the adapter tongs/Mini
adapter tongs (19) into the drive unit and lock the tongs retaining bolt. Press
the adapter tongs/Mini adapter tongs (19) together with your hand so that the
adapter tongs/Mini adapter tongs can be placed on the pressing ring. Release
the adapter tongs/Mini adapter tongs so that the radii/hemispheres of the adapter
tongs/Mini adapter tongs lie fi rmly on the cylinder rollers/ball sockets of the
pressing ring and the pressing ring on the press fi tting. With adapter tongs Z1
and Mini adapter tongs Z1, please note that the pressing ring may only be
applied below 45°.
NOTICE
Only use the adapter tongs approved for the pressing ring, see 2.2. Failure to
do so can lead to faulty or leaking pressings and could also damage the pressing
ring or adapter tongs.
On REMS Power-Press SE push the rotation direction lever (7) to the right
(feed) and press the safety inching switch (8). Keep the safety inching switch
(8) pressed until the pressing is fi nished and the pressing tongs or pressing
ring are closed. Release the safety inching switch immediately. Push the rota-
tion direction lever (7) to the left (return) and press the switch (8) until the press
rollers have moved back and the safety slip clutch responds. Release the safety
inching switch immediately.
NOTICE
Do not needlessly stress the safety slip clutch. Release the safety inching switch
immediately after closing the pressing tongs, the pressing ring or moving back immediately
the pressing rollers. The safety slip clutch is subject to normal wear like any
slip clutch. However, if it is needlessly stressed, it wears more quickly and can
be destroyed.
In the case of the REMS Power-Press and REMS Akku-Press, keep the safety
inching switch (8) pressed until the pressing is fi nished and the pressing tongs
or pressing ring is completely closed. This is indicated by an acoustic signal
(clicking). Press the reset button (13) until the press rollers (5) are fully retracted.
In the case of the REMS Mini-Press ACC, EMS Mini-Press ACC, REMS Mini-Press 22 V ACC, REMS
Mini-Press S 22 V ACC, REMS Akku-Press ACC, REMS Akku-Press XL 45 kN Mini-Press S 22 V ACC,
22 V ACC, REMS Power-Press ACC and REMS Power-Press XL ACC, keep
the safety inching switch (8) pressed until the pressing is fi nished and the
pressing tongs or pressing ring is completely closed. After completion of press ing,
the drive unit switches automati cally to return (forced return). This is indicated
by an acoustic signal (click).
On REMS Akku-Press 22 V ACC, keep the safety inching switch (8) pressed
until the pressing tongs or the pressing ring are fully closed. Upon completion
of the pressing, the drive unit switches over automatically to retraction (automatic
circuit control). The coloured LED of the pressure indicator (28) indicates
whether the pressure of the drive unit was within the specifi cation, see 3.6.
Press the pressing tongs, pressing tongs Mini together with your hand so that
they can be removed from the pressfi tting together with the drive unit. Press
the adapter tongs, adapter tongs Mini together with your hand so that they can
be removed from the pressing ring together with the drive unit. Open the pressing
ring by hand so that it can be pulled off the pressfi tting.
3.1.2. Operating safety
On REMS Power-Press SE the pressing process is ended by releasing the
safety inching switch (8). A torque-dependent safety slip clutch acts in both end
positions of the press rollers for the mechanical safety of the drive unit. Do not
needlessly stress the safety slip clutch! REMS Power-Press SE is also equipped
with an electronic safety circuit which switches off the drive unit at high load.
As long as the pressing tongs (1), pressing rings (20) close fully, see 3.1, this
is uncritical. However, if the drive unit switches off before pressing is completed
(pressing tongs, pressing rings were not closed, see 3.1), work must not continue
and the drive unit must be inspected/repaired immediately by an authorised
REMS contract service workshop.
The REMS Power-Press and REMS Akku-Press ends the pressing opera tion
automatically, emitting an acoustic signal (clicking).
The REMS Mini- Press ACC, REMS Mini- Press ACC 22 V, REMS Mini- Press ACC, REMS Mini- Press ACC 22 V, REMS Mini-Press S
