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 in-
ching 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 nee-
ded for one pipe size. Consult and comply with the instructions for instal-
lation 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. Be-
fore 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 fit-
ting 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 ne-
cessary repeat the expansion. Consult and comply with the instructions
for installation and fitting of the system's manufacturer.
3.3. REMS Akku-Ex-Press Mini Q & E, REMS Akku-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 instructions for installation and
fitting of the system's manufacturer.
4. Maintenance
Important! Irrespective of the above maintenance work, the REMS drive
units must be returned together with all tools (for ex. pressing tongs, pres-
sing heads, expanding heads) at least once a year to an authorised REMS
after-sales service facility for inspection.
4.1. Maintenance
Before maintenance work, pull the mains plug or remove the battery.
Keep the pressing tongs, pressing heads and expanding heads, and par-
ticularly their receptacles, clean. Clean heavily soiled metal parts with tur-
pentine 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 con-
tain chemicals that can attack plastic parts. On no account use petrol, tur-
pentine oil, thinners or similar products to clean plastic parts.
Ensure that liquids never get inside the electrical equipment. Never im-
merse the electrical equipment in liquid.
4.1.1. Pressing tongs
Check the pressing tongs for easy action at regular intervals. If necessary
clean the pressing tongs and lubricate the bolts (12) of the pressing jaws
with machine oil, however do not dismantle the pressing jaw! Remove any
deposits in the pressing contour (11). Check that all pressing tongs are
functional at regular intervals by a trial pressing operation with the press
fitting inserted. The pressing jaws (10) must close (10) both at their tips
(Fig. 1, at "A") and at the level of the connecting link (Fig. 1, at "B") after
completion of pressing. Do not use damaged or worn pressing tongs again.
If in doubt, return the drive unit together with all pressing 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 rol-
lers (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 Mini-Press ACC and 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 authorised 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) cle-
an. Lightly grease the expanding mandrel (18) from time to time.
4.1.4. REMS Akku-Ex-Press Mini Q & E, REMS Akku-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
Before any repair work, pull the mains plug or remove the battery. This
work may only be performed by authorised experts or by trained person-
nel.
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 Akku drive
units operate electrohydraulically. If the pressing power is insufficient or
oil is lost, the drive unit must be inspected and if necessary repaired by
REMS or by an authorised REMS after-sales service facility.
Damaged or worn pressing tongs, pressing heads or expanding heads
cannot be repaired.
