not possible in some cases and pre-pressing and finish pressing is necessary.
For this, one compression head or both compression heads must be inserted
turned 180° before the second pressing process so that they are closer together.
The closer distance may have to be reached by moving the outer compression
head to the middle compression head position. Read and follow the installation
and assembly instructions of the system manufacturer.
CAUTION Danger of cru shing! Keep your hands away from the moving
pressing heads (14)!
3.2.2. Expansion with REMS Ax-Press 15 (Fig. 6)
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 s ion 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 ACC, REMS Power-Ex-Press Q & E ACC
(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 p ipe. Insert the
expansion head into the pipe and press the expanding h ead/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 in the REMS Akku-Ex-Press
Q & E ACC and push the expanding head/drive unit further. Turn the pipe
slightly. Keep repeating the expansion process until the expanding jaws (17)
are slid all the way into the pipe. Release the inching switch (8) after every
expanding process in the REMS Power-Ex-Press Q & E ACC, wait until the
expanding mandrel has moved back completely and then press the inching
switch (8) again. Repeat the expanding process until the expanding jaws (17)
are pushed into the pipe up to the stop.
Expanding with REMS Akku-Ex-Press P ACC, REMS Akku-Ex-Press Cu
ACC (Fig. 11, 12)
Push the compression sleeve over the pipe in the REMS Akku-Ex-Press P
ACC, insert the expanding head into the pipe up to the stop and press the
expanding head/drive machine against the pipe. Switch on the drive machine
(8). Make sure that the compression sleeve is far enough away from the
expanding head in the expanding process because otherwise the expanding
jaws (17) can bend or break. Keep the inching switch (8) pressed until the pipe
is expanded. This is indicated by an acoustic signal (click). Expand several
times if necessary. Turn the pipe slightly. Read and follow the installation and
assembly instructions of the system manufacturer.
In the REMS Akku-Ex-Press Cu ACC, insert the expanding head into the pipe
up to the stop and press the expanding head/drive machine against the pipe.
Switch on the drive machine. If the expanding head is open, the drive machine
switches automatically to return and the expanding head is closed again. Read
and follow the installation and assembly instructions of the system manufacturer.
3.4. Electronic battery charging status check with complete discharge protec-
tion
All REMS Akku presses made as of 2011-01-01 will be fitted with an electronic
battery charging status check with complete discharge protection and battery
charge indicator with 2-colour LED (23) green/red. The LED lights green when
the battery is fully or still sufficiently charged. The LED lights red when the
battery must be charged. The drive unit finishes off the current pressing cycle
and can then only be switched on again when a charged battery is inserted. If
the drive unit is not used, the LED goes out after 2 hours but comes on again
when the tool is switched back on.
4. Maintenance
WARNING
Notwithstanding the maintenance listed below it is necessary
to send in the REMS drive units together with all the tools (e.g. pressing tongs,
pressing tongs Mini, pressing rings with adapter tongs, compression heads,
expanding heads) at least once a year to an authorised REMS customer service
station for inspection. This opportunity is also taken to carry out the prescribed
annual inspection of electrical equipment in accordance with EN 62638 (VDE
0702) for power tools.
4.1. Maintenance
WARNING
Before maintenance work, pull the mains plug or remove
the battery!
Keep the pressing tongs, pressing tongs Mini, pressing rings, adapter tongs,
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, pressing tongs Mini, pressing rings and adapter tongs
Pressing tongs, pressing tongs Mini, pressing rings and adapter tongs must
be checked regularly for smooth action. Clean pressing tongs, pressing tongs
Mini, pressing rings and adapter tongs if necessary and lightly grease 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 func-
tioning of all pressing tongs, pressing tongs Mini, pressing rings and adapter
tongs regularly with a test pressing with inserted pressing fitting. A perfect
pressing is only produced with full closure of the pressing tongs, pressing tongs
Mini, pressing ring or pressing segment. Full closure of the pressing jaws (10),
pressing rings (20) or pressing segment (21) both at their tips (Fig. 1 and Fig.
16 to 19 at "A") and on the opposite side (Fig. 1 and Fig. 16 to 19 at "B") can
be observed after completing the pressing. If a visible burr is created on the
pressing sleeve when closing the pressing tongs, pressing tongs Mini, pressing
ring or pressing segment, the pressing may be faulty or leaking (see 5. Trouble).
Damaged or worn pressing tongs, pressing tongs Mini, 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 tongs Mini, pressing rings
and adapter tongs to an authorised REMS service shop 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 lightly grease them with
machine oil. Check the functional reliability of the drive unit r egularly by making
a pressing with the largest press fitting used. If the pressing tongs, pressing
tongs Mini, pressing rings close completely during this pressing operation (see
above), the drive unit is functionally reliable.
4.1.3. Axial presses
Keep the pressing heads (14) and locating holes inside the pressing d evice
clean. Keep the expanding heads (16) and expanding mandrel (18) clean.
Lightly grease the expanding mandrel (18) from time to time.
4.1.4. Pipe expanders
Keep the expanding device (15), expanding heads (16) and expanding mandrel
(18) in REMS Akku-Ex-Press Q & E ACC, REMS Power-Ex-Press Q & E ACC,
REMS Akku-Ex-Press P ACC, and REMS Akku-Ex-Press Cu ACC clean. Grease
the expanding mandrel (18) lightly 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.
An annual inspection is necessary for all pressing/expanding tools (including
pressing tongs, pressing tongs Mini, pressing rings, adapter tongs, compression
heads, expanding heads).
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 and REMS Power-Press ACC has
carbon brushes. These are subject to wear and must therefore be inspected
or r eplaced from time to time. O nly use genuine REMS Power-Press carbon
brushes. The REMS d rive units (except for REMS Power-Press E) 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 f acility.
NOTICE
Damaged or worn pressing tongs, pressing tongs Mini, pressing
rings, adapter tongs, pressing heads or expanding heads cannot be repaired.
5. Trouble
