If during closing of the pressing tongs a marked ridge is created on the compres-
sion sleeve, the pressing may be defective or not tight (see 5. Trouble).
3.1.1. Working procedure
Press the pressing tongs (1) together manually until they can be pushed over
the press fitting. Always position the drive unit with the pressing tongs on the
press fitting at right angles to the pipe axis. Release the pressing tongs so that
they close around the press fitting. Hold the drive unit by the housing grip (6)
and the pistol grip (9).
Place the pressing ring (20) around the pressing fitting. Insert the pressing tong
(19) into the press and lock the tong retaining bolt. Press the pressing tong
(19) together with your hand so that the adapter tong can be placed on the
pressing ring. Release the adapter tong so that the adapter tong is tightly applied
to the pressing ring and the pressing ring to the pressfitting.
In the case of the REMS Power-Press E, set the rotation direction lever (7) to
the right (advance) and press the inching switch (8). Keep the inching switch
(8) pressed until the pressing is finished and the pressing tong or pressing ring
is closed. Set the rotation direction lever (7) to the left (return) and press the
switch (8) until the press rollers have retracted and the slipping clutch responds.
Do not put unnecessary loads on the slipping clutch.
In the case of the REMS Power-Press and REMS Akku-Press, keep the inching
switch (8) pressed until the pressing is finished and the pressing tong 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, REMS Akku-Press ACC and REMS
Power-Press ACC, keep the inching switch (8) pressed until the pressing is
finished and the pressing tong or pressing ring is completely closed. After
completion of press ing, the drive unit switches automati cally to return (forced
return).
Press the pressing tongs together manually so that they can be removed from
the press fitting. Press the pressing tong together with your hand so that it can
be removed from the pressfitting. Press the adapter tong together with your
hand so that it can be removed from the pressing ring with the device. Open
the pressing ring by hand so that it can be pulled off the pressfitting.
3.1.2. Operating safety
In the case of the REMS Power-Press E, the pressing operation is ended by
releasing the inching switch (8). For the mechanical safety of the drive units,
a torque-controlled safety slipping clutch is operative in both end positions of
the press rollers.
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 Akku-Press ACC and REMS Power-Press ACC ends the pressing
operation automatically, emitting an acoustic signal (clicking), and returns
automatically (forced movement).
NOTICE
A perfect pressing is only made with the full closing of the
pressing tong or adapter tong and pressing ring. Full closure of the
pressing jaws (10) or pressing segments (21) both at their tips (Fig. 1 and
Fig. 14, at "A") and at the height of the connecting lug (Fig. 1 and Fig. 14
at "B") can be observed after completing the pressing. If a visible burr is
created on the pressing sleeve when closing the pressing tong or pressing
segment, the pressing may be faulty or leaking (see 5. Trouble).
3.1.3. Working safety
To ensure safe working, the drive units are equipped with a safety inching
switch. This permits immediate switching off of the drive units at any time,
particularly if a potential hazard arises. The drive units can be switched to the
return function in any position.
3.2. Axial presses (Figs. 6, 7)
3.2.1. Pressing with the REMS Ax-Press 15 and Ax-Press 40
Place the preassembled compression sleeve fitting inside the pressing heads
(14) and press them into the latter. Only press the inching switch (8) lightly, so
that the pressing heads move together slowly until they are in contact with the
compression sleeve fitting.
CAUTION Danger of cru shing! Keep your hands away from the moving
pressing heads! Hold the drive unit by the housing grip (6) and the pistol grip
(9), and keep the inching switch (8) pressed until the compression sleeve is in
contact with the collar of the compression sleeve fitting. This is also indicated
by an acoustic signal (clicking). Press the reset button (13) until the pressing
heads (14) are fully retracted.
With the compression sleeve system IV, various pressing heads are needed
for one pipe size. Consult and comply with the instructions for installation and
fitting of the system's manufacturer.
In the case of the compression sleeve system RV, preliminary and final pressing
is necessary, i.e. the pressing heads must first be inserted with a wide spacing
of the receptacles for the compression sleeve fitting. Before a second pressing
operation, the pressing heads are set to a narrow spacing of the receptacles
for the compression sleeve fitting by a 180° rotation. Consult and comply with
the instructions for installation and fitting of the system's manufacturer.
3.2.2. Expansion with REMS Ax-Press 15
Push the compression sleeve over the pipe, insert the expanding head as far
as it will go into the pipe, and press the expanding head/drive unit against the
pipe. Switch on the drive unit (8). Ensure that the compres sion sleeve has
during the expansion process sufficient clearance from the expanding head,
otherwise the expanding jaws (17) might become bent or broken. Hold down
the inching switch (8) until the pipe has been expanded. This is also indicated
by an acoustic signal (clicking). Press the reset button (13) until the expanding
head has closed again. If necessary repeat the expansion. Consult and comply
with the instructions for installation and fitting of the system's manufacturer.
3.3. REMS Akku-Ex-Press Q & E, REMS Power-Ex-Press Q & E (Fig. 8)
Consult and comply with the instructions for installation and fitting of the system's
manufacturer. Slide a Q & E ring of appropriate size onto the pipe. Insert the
expansion head into the pipe and press the expanding head/drive unit against
the pipe. Switch on the drive unit (8). When the expanding head is opened, the
drive unit switches automatically to return and the expanding head is closed
again. Keep holding the inching switch (8) down and push the expanding head/
drive unit further. Keep repeating the expansion process until the expanding
jaws (17) are slid all the way into the pipe. Consult and comply with the instruc-
tions for installation and fitting of the system's manufacturer.
4. Maintenance
NOTICE
Irrespective of the above maintenance work, the REMS drive units
must be returned together with all tools (for ex. pressing tongs, pressing heads,
expanding heads) at least once a year to an authorised REMS after-sales
service facility for inspection.
4.1. Maintenance
WARNING
Before maintenance work, pull the mains plug or remove
the battery!
Keep the pressing tongs, adapter tongs, pressing rings, pressing heads and
expanding heads, and particularly their receptacles, clean. Clean heavily soiled
metal parts with turpentine oil, for example, and then rustproof them.
Clean plastic parts (for ex. housing, batteries) only with a mild soap and a damp
cloth. Do not use domestic cleaning agents. These frequently contain chemicals
that can attack plastic parts. On no account use petrol, turpentine oil, thinners
or similar products to clean plastic parts.
Ensure that liquids never get inside the electrical equipment. Never immerse
the electrical equipment in liquid.
4.1.1. Pressing tongs, adapter tongs and pressing rings
Pressing tongs, pressing rings and adapter tongs must be checked regularly
for smooth action. Clean pressing tongs, pressing rings and adapter tongs if
necessary and lubricate the bolts (12) of the pressing jaws, pressing segments
and adapter jaws with machine oil. Remove deposits from the pressing contour
(11). Check the proper functioning of all pressing tongs, pressing rings and
adapter tongs regularly with a test pressing with inserted pressing fitting. The
pressing jaws (10) must close fully both at their tips (Fig. 1, at "A") and at the
height of the connecting lug (Fig. 1 at "B") after completing the pressing. The
pressing segments (21) must closed after completing the pressing. Damaged
or worn pressing tongs, pressing rings and adapter tongs may no longer be
used. In case of doubt, send in the drive machine together with all pressing
tongs, pressing rings and adapter tongs to an authorised REMS after-sales
service facility for inspection.
4.1.2. Radial presses
Keep the press tongs receptacle clean, in particular clean the press rollers (5)
and tongs shank (2) at regular intervals and then lubricate them with machine
oil. Check the functional reliability of the drive unit regularly by making a pressing
with the largest press fitting used. If the pressing tongs close completely during
this pressing operation (see above), the drive unit is functionally reliable.
The REMS Akku-Press ACC is fitted with an electronic servicing feature. After
about 10,000 pressing operations, the diode on the pistol grip (9) starts to flash.
An inspection is then due. This is performed by an autho rised REMS after-sales
service facility.
4.1.3. Axial presses
Keep the pressing heads (14) and locating holes inside the pressing device
clean. Keep the expanding heads (16) and expanding mandrel (18) clean.
Lightly grease the expanding mandrel (18) from time to time.
4.1.4. REMS Akku-Ex-Press Q & E, REMS Power-Ex-Press Q & E
Keep the expanding heads (16) and expanding mandrel (18) clean. Lightly
grease the expanding mandrel (18) from time to time.
4.2. Inspection/repair
WARNING
Before any repair work, pull the mains plug or remove the
battery! This work may only be performed by qualified personnel.
After around 10,000 pressing/expanding operations, but at least once a year,
inspection of the pressing/expanding tool to an authorised REMS after -sales
service facility is necessary.
The gearbox of the drive unit in the REMS Power-Press E is maintenance -free.
They operate in a permanent grease filling and therefore require no lubrication.
The motor of the REMS Power-Press E, REMS Power-Press and REMS Power-
Press ACC has carbon brushes. These are subject to wear and must therefore
be inspected or replaced from time to time. Only use genuine REMS Power-
Press carbon brushes. The REMS drive units (except for REMS Power-Press
