inserted into the drive unit in such a way that the pressing can be made in one 

stroke if possible. This is not possible in some cases and pre-pressing and 

fi nish pressing is necessary. For this, one pressing head or both pressing heads 

must be inserted turned 180° before the second pressing process so that they 

are closer together.

Working procedure

CAUTION

CAUTION   

Danger of cru shing! Keep your hands away from the moving pressing 

heads (5)!
In ROLLER’S Axial-Press 25 22 V ACC, ROLLER’S Axial-Press 25 L 22 V ACC 

(Fig. 1), place the preassembled compression sleeve fi tting inside the pressing 

heads (5). On the ROLLER’S Axial-Press 25 L ACC the closer distance of the 

pressing heads may have to be achieved by moving the outer pressing head 

into the centre pressing head position. Hold the drive machine either with one 

hand on the switch handle (3) or two hands on the housing handle (1) and the 

switch handle (3). Keep the safety inching switch (2) pressed until the compres-

sion sleeve is touching the collar of the compression sleeve connector. The 

drive machine then switches automatically to return (forced return).

If there is a noticeable gap between the compression sleeve and the collar of 

the compression sleeve connector after closing the compression heads, the 

pressing may be faulty or leaking (see 5. Faults). Read and observe the instal-

lation and assembly instructions of the manufacturer/supplier of the pressing 

sleeve system to be pressed.

With the compression sleeve system IV, various pressing heads are needed 

for one pipe size. Consult and comply with the instructions for installation and 

fi tting of the system’s manufacturer. 

3.2.  Pipe expanders
 

Working procedure

In ROLLER’S Exparo 22 V ACC with expander Cu (Fig. 2), insert the expanding 

head into the pipe up to the stop and press the expanding head/drive unit 

against the pipe. Switch on the drive unit. If the expanding head is open, the 

drive unit switches automatically to return and the expanding head is closed 

again. Read and observe the installation and assembly instructions of the 

manufacturer/supplier of the used system.

In ROLLER’S Exparo 22 V ACC with expander P (Fig. 2), push the compression 

sleeve over the pipe, insert the expanding head into the pipe up to the stop 

and press the expanding head/drive unit against the pipe. Switch on the drive 

unit. Make sure that the compression sleeve is far enough away from the 

expanding head in the expanding process because otherwise the expanding 

jaws (8) can bend or break. Keep the safety  inching switch (2) 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 observe the instal-

lation and assembly instructions of the manufacturer/supplier of the used system.
In ROLLER’S Exparo 22 V ACC with expander P-CEF (Fig. 2), read and observe 

the installation and assembly instructions of the manufacturer/supplier of the 

used system. Push a ring of the appropriate size onto the pipe.Insert the expan-

sion head into the pipe and press the expanding  head/drive unit against the 

pipe. Switch on the drive unit. When the expanding head is opened, the drive 

unit switches automatically to return and the expanding head is closed again. 

Keep holding the safety inching switch (2) down in the ROLLER’S Exparo 22 V 

ACC and push the expanding head/drive unit further. Turn the pipe slightly. 

Keep repeating the expansion process until the expanding jaws (8) are slid all 

the way into the pipe.

3.3.  Safety during operation
 

Functional safety

ROLLER’S Axial-Press 25 22 V ACC, ROLLER’S Axial-Press 25 L 22 V ACC 

and ROLLER’S Exparo 22 V ACC end the pressing operation automatically, 

emitting an acoustic signal (clicking) and return automatically (automatic circuit 

control).

Working safety

To ensure safe working, the drive units are equipped with a safety inching switch 

(2). This permits immediate switching off of the drive units at any time, parti-

cularly if a potential hazard arises. The drive units can be switched to the return 

function in any position. 

3.4.  Machine status check with fl at battery protection

All ROLLER’S Akku presses have been equipped with an electronic machine 

status check with charging level indicator (10) with a 2-coloured green/red LED 

since 01/01/2011. 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 (13) of the Li-Ion 21.6 V battery

level of the battery. If a LED fl ashes red, the bat

3.6.  Power supply unit (accessory art. no. 571567, 571578)

571567, 571578

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 

55

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 

ROLLER’S 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 ROLLER 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 

ROLLER 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 ROLLER customer service station for inspec-

tion and repeated inspection of electrical equipment in accordance with EN 

62638:2010-08 (VDE 0702).

4.1. Servicing

WARNING

WARNING

 Before service work, pull the mains plug or remove the battery! 

Keep pressing heads and expanding heads, and particularly their receptacles, 

clean. Clean heavily soiled metal parts with machine cleaner and then protect 

against rust.
Clean plastic parts (e.g. 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.

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 

Before any repair work, pull the mains plug or remove the battery!

Before any repair work, pull the mains plug or remove the battery!

work may only be performed by qualifi ed personnel.
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 ROLLER customer service station.

NOTICE

Do not attempt to repair damaged or worn pressing heads and expanding 

heads.
