The specifi ed vibration emission value was measured according to a standard 

test method and can be used for comparison with another power tool. The 

specifi ed vibration emission value can also be used for an initial estimation of 

the cut-out.

CAUTION

CAUTION   

The vibration emission value may differ from the specifi ed value during actual 

use of the power tool depending on the manner in which the power tool is used.

Dependent upon the actual conditions of use (periodic duty) it may be necessary 

to establish safety precautions for the protection of the operator.

2.1.  Electrical connection

WARNING

WARNING

Note the mains voltage! Before connecting the drive unit, the rapid charger 

or the power supply unit, check whether the voltage given on the rating plate

corresponds to the mains voltage. On building sites, in a wet environment, 

indoors and outdoors or under similar installation conditions, only operate the 

power tool on the mains with a fault current protection switch (FI switch) which 

interrupts the power supply as soon as the leakage current to earth exceeds 

30 mA for 200 ms.

Rechargeable batteries

 Total discharging by undervoltage

The Li-Ion batteries may not drop below a minimum voltage because otherwise 

the battery could be damaged by total discharge. The cells of the ROLLER

Li-Ion battery are delivered pre-charged to approx. 40 %. Therefore the Li-Ion 

batteries must be charged before use and recharged regularly. Failure to observe 

this regulation of the cell manufacturer can lead to damage to the Li-Ion battery 

by total discharging.

Total discharging due to storage

If a relatively low charged Li-Ion battery is stored, self discharging can lead to 

total discharge damage of the battery after longer storage. Li-Ion batteries must 

therefore be charged before storing and recharged every six months at the 

latest and charged again before use.

NOTICE

Charge the battery before use. Recharge Li-Ion batteries regularly to avoid 

their total discharge. The rechargeable battery will be damaged by total 

discharge.
Only use approved ROLLER rapid chargers for charging the

Remove the battery. Only use system-specifi c pressing heads. ROLLER’S

press ing heads have a letter to identify the compression sleeve system and a 

number to identify the size. Read and observe the installation and assembly 

instructions of the manufacturer/supplier of the used compression sleeve system. 

Never use non-matching pressing heads (compression sleeve system, size) 

for pressing work. The press joint could be unserviceable, and both the machine 

and the press ing heads might be damaged. 

Push the selected pressing heads (

Push the selected pressing heads (5) right in, if necessary turning them until

they engage (ball catch). Keep the pressing heads and locating hole inside the 

pressing device clean.

2.3.  Assembly (changing) of the expander (6), the expanding head (7) on 

ROLLER’S Exparo 22 V ACC (Fig. 2)

22

Choose an expander (6) to match the expanding head (7). Use the expander 

Cu for the ROLLER’S Cu expanding heads. Use the expander P for the 

ROLLER’S P expanding heads. Use the P-CEF expander for the ROLLER’S 

expanding heads. Only use system-specifi c expanding heads. ROLLER’S P 

and ROLLER’S P-CEFexpanding heads are labelled with letters to identify the 

compression sleeve system and a number to identify the size, ROLLER’S Cu 

expanding heads only with a number to identify the size. Read and observe 

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

used system. Never expand with an unsuitable expander, unsuitable expanding 

heads (system, size). The joint could be useless and the machine and expanding 

heads could be damaged. Grease the cone of the expanding mandrel (9) lightly. 
Changing the P and Cu expander

Screw the selected expanding head onto the expanding device (6) to the stop.

the expander with screwed-on expanding head must be screwed onto the drive 

unit until the expanding jaws (8) of the expanding head (7) are fully open. The 

expanding head must be secured with the locking nut (11) in this position.

NOTICE

Make sure that the compression sleeve is far enough away from the expanding 

head (7) in the expanding process because otherwise the expanding jaws (8)

can bend or break.
Changing the P-CEF expander

Remove the battery. Screw on the locking nut (11) and the selected expander 

(6) up to the stop. Screw the selected expanding head (7) onto the expander 

up to the stop.

3. Operation

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 ROLLER customer service workshop for inspectio
