Maintenance - REMS Power-Press Instruction Manual

(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.
3.4. Battery charging status check with complete discharge protection
All REMS cordless presses made as of 2011-01-01 are equipped with an
electronic battery charging status check with battery charge indication by a
2-coloured green/red LED (23). The LED lights green when the battery is fully
or still suffi ciently charged. The LED lights red when the battery must be charged.
If this condition occurs during pressing and the pressing process is not fi nished,
the pressing must be completed with a fully charged Li-Ion battery. If the drive
unit is not used, the LED goes out after approx. 2 hours but comes on again
when the drive unit is switched back on.
3.5. Graduated charging level indicator (26) of the Li-Ion 21.6 V battery
The graduated charging level indicator shows the charging level of the battery
with 4 LEDs. At least one LED lights for a few seconds after pressing the key
with the battery symbol. The more LEDs that light green, the higher the charging
level of the battery. If a LED fl ashes red, the battery must be recharged.

4. Maintenance

Notwithstanding the maintenance mentioned below, it is recommended to send
in the REMS drive units together with all tools (e.g. pressing tongs, Mini pressing
tongs, pressing rings with adapter tongs, Mini adapter tongs, pressing heads,
expanding heads) and accessories (e.g. batteries, rapid chargers) at least once
a year to an authorised REMS contract customer service workshop for inspec-
tion and re-inspection of electrical devices. In Germany, such periodic testing
of electrical devices should be performed in accordance with DIN VDE 0701-
0702 and also prescribed for mobile electrical equipment according to the
accident prevention rules DGUV, regulation 3 "Electrical Systems and Equip-
ment". In addition, the respective national safety provisions, rules and regula-
tions valid for the application site must be considered and observed.
WARNING
Notwithstanding the servicing listed below it is recommended to send in the
REMS drive units together with all the tools (e.g. pressing tongs, pressing tongs
Mini, pressing rings with adapter tongs, adapter tongs Mini, compression heads,
expanding heads) and accessories (e.g. batteries, rapid chargers) at least once
a year to an authorised REMS customer service station for inspection and
repeated inspection of electrical equipment in accordance with EN 62638:2010-08
(VDE 0702).
4.1. Inspection/repair
WARNING
Before any repair work, pull the mains plug or remove the battery! This
work may only be performed by qualifi ed personnel.
The gearbox of the drive unit in the REMS Power-Press SE is maintenance -
free. They operate in a permanent grease fi lling and therefore require no
lubrication. The motor of the REMS Power-Press SE, REMS Power-Press,
REMS Power-Press ACC, REMS Power-Press XL ACC and REMS Power-
Ex-Press Q & E ACC has carbon brushes. These are subject to wear and must
therefore be inspected or replaced from time to time. Only use genuine REMS
carbon brushes. The REMS Power-Press SE drive unit has a safety slip clutch.
This is subject to wear and must therefore be checked and renewed from time
to time. Use only an original REMS safety slip clutch. In the battery-operated
drive units, the carbon brushes of the motor are subject to wear. These cannot
be replaced; the DC motor must be replaced. The sealing rings (O-rings) wear
in all electro-hydraulic drive units. These must therefore be checked and renewed
from time to time. If the pressing power is insuffi cient or oil is lost, the drive unit
must be inspected and if necessary repaired by an authorised REMS after-sales
service facility.
5. Trouble
For preventing damages make sure to avoid operating situations like exemplarily shown in Fig. 12 through 14, that no distortion between pressing tongs, pressing
tongs Mini, pressing rings, adapter tongs, adapter tongs Mini, fi tting and drive unit occurs.
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.
5.1. Fault: Drive unit does not work.
Cause:
● Worn carbon brushes.
● Mains lead defective (REMS Power-Press SE, REMS Power-Press,
REMS Power-Press ACC, REMS Power Press XL ACC,
REMS Power-Ex-Press Q & E ACC).
● Battery depleted or defective (REMS cordless drive units).
● Drive unit defective.
NOTICE
Damaged or worn pressing tongs, pressing tongs Mini, pressing rings, adapter
tongs, pressing heads or expanding heads cannot be repaired.
4.2. Servicing
WARNING
Before service work, pull the mains plug or remove the battery!
Keep the pressing tongs, pressing tongs Mini, pressing rings, adapter tongs,
adapter tongs Mini pressing heads and expandin , and particularly their recep-
tacles, clean. Clean heavily soiled metal parts with the REMS CleanM (Art. No.
140119) cleaner, for example, and then protect against rust.
Clean plastic parts (e.g. housing, batteries) only with the REMS CleanM (Art. No.
140119) or 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.
Make sure that liquids never get inside the power tool. Never immerse the
power tool in liquid.
4.2.1. Pressing tongs, pressing tongs Mini, pressing rings, adapter tongs, adapter
tongs Mini
Pressing tongs, pressing tongs Mini, pressing rings, adapter tongs, adapter
tongs Mini tongs Mini must be checked regularly for smooth action. Clean pressing tongs, tongs Mini must be checked regularly for smooth action. Clean pressing tongs,
pressing tongs Mini, pressing rings and adapter tongs, adapter tongs Mini if
necessary and lightly grease the bolts (12) of the pressing jaws, pressing
segments and adapter jaws, adapter tongs Mini (Fig. 1, 15 – 19) with machine
oil. Remove deposits from the pressing contour (11, 22). Check the proper
functioning of all pressing tongs, pressing tongs Mini, pressing rings, adapter
tongs, adapter tongs Mini regularly with a test pressing with inserted pressing
fi tting. 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. 15 – 19 at "A") and on the opposite side (Fig. 1 and
Fig. 15 – 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, adapter
tongs, adapter tongs Mini may no longer be used. In case of doubt, send in the
drive machine together with all pressing tongs, pressing tongs Mini, pressing
rings, adapter tongs, adapter tongs Mini to an authorised REMS service shop
for inspection.
4.2.2. 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 safety of the drive unit regularly by making
a pressing with the press fi tting that requires the greatest pressing force. If the
pressing tongs, Mini pressing tongs, pressing ring or pressing segments close
completely in this pressing (see above), the drive unit is functioning reliably.
4.2.3. Axial presses
Keep the compression heads (14) and mounting bores in the pressing device
and the pressing device itself clean.
4.2.4. Pipe expanders
Keep the expanding device (15), expanding heads (16) and expanding mandrel
(18) in REMS Akku-Ex-Press Cu ACC, REMS Akku-Ex-Press P, REMS Akku-
Ex-Press P ACC, REMS Akku-Ex-Press Q & E ACC, REMS Power-Ex-Press
Q & E ACC clean. Grease the expanding mandrel (18) lightly from time to time.
Remedy:
● Have the carbon brushes or DC motor changed by qualifi ed personnel or an
authorised REMS customer service workshop.
● Have the mains lead replaced by qualifi ed personnel or an authorised REMS
customer service workshop.
● Charge the battery with the Li-Ion/Ni-Cd rapid charger or change the battery.
● Have the drive unit checked/repaired by an authorised REMS customer service
workshop.
