3.6. Power supply unit (accessory art. no. 571567, 571578)
The power supply units are intended for mains operation of the cordless tools in
place of the battery. See the guidelines for use (Fig. 5) for the intended use. The
power supply units are equipped with overvoltage and temperature protection.
The operating state is indicated by a LED. A lit LED indicates that the device is
ready for operation. If the LED goes out or fl ashes, this indicates an overcurrent
or impermissible temperature. The drive unit cannot be used during this time.
After a dwell time, the LED lights again and work can be continued.
NOTICE
The power supply units are not suitable for outdoor use.
4. Maintenance
Notwithstanding the servicing listed below it is recommended to send in the
REMS drive units together with all the tools (e.g. pressing heads, expanding
heads) and accessories (e.g. batteries, rapid chargers, power supply units) at
least once a year to an authorised REMS customer service station for inspec-
tion and repeated inspection of electrical equipment. 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
Equipment". In addition, the respective national safety provisions, rules and
regulations valid for the application site must be considered and observed.
WARNING 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. Servicing
WARNING WARNING

Cause:
● Expansion too long.
● Pipe pushed too wide onto the support sleeve of the press fi tting.
● Wrong expanding head (press fi tting system, size) inserted.
● Unsuitable matching of press fi tting, pipe and support sleeve.
5.3. Fault: A prominent gap is left between the press fi tting and the fi tting joint after closing the pressing heads in axial pressing.
Cause:
● Pipe crushed between the compression sleeve and the fi tting collar
● Wrong compression head (compression sleeve system, size) used.
● Battery depleted or defective (REMS cordless drive units).

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.
Axial presses
Keep the compression heads (5) and mounting bores in the pressing device
and the pressing device itself clean.
Pipe expanders
Keep the expander (6), expanding heads (7) and expanding mandrel (9) clean.
Grease the expanding mandrel (9) lightly from time to time.
4.2. Inspection/repair
WARNING WARNING
Before any repair work, pull the mains plug or remove the battery! This
work may only be performed by qualifi ed personnel.
The motor of REMS Power-Ex-Press P-CEF ACC has carbon brushes. These
wear and must therefore be checked and renewed from time to time. Only use
original REMS carbon brushes. 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 customer service station.
NOTICE
Do not attempt to repair damaged or worn pressing heads and expanding
heads.
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 rapid charger or change the battery.
● Have the drive unit checked/repaired by an authorised REMS customer service
workshop.
Remedy:
● Check whether the right expanding head was used. Pipe expanded several
times, observe the installation and assembly instructions of the manufacturer/
supplier of the press fi tting system to be pressed.
● Check whether the right expanding head was used. Pipe expanded several
times, observe the installation and assembly instructions of the manufacturer/
supplier of the press fi tting system to be pressed.
● Change expanding head.
● Check the compatibility of the press fi tting, pipe and support sleeve and contact
the manufacturer/supplier of the press fi tting system to be pressed if necessary.
Remedy:
● See fault 5.2.
● Change pressing head.
● Charge the battery with the rapid charger or change the battery.
● Have the drive unit checked/repaired by an authorised REMS customer service
workshop.
