Machine status check for all Li-Ion cordless presses

All ROLLER’S cordless presses are available as of 2011-01-01 with an electronic 

machine status check with charging state display (23) by a 2-coloured green/

red LED. 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.

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.
Rapid charger Li-Ion/Ni-Cd and rapid charger Li-Ion (Art. No. 571560, 

571575, 571585, 571587)

The left control lamp lights up and remains green when the mains plug is 

plugged in. If a battery is inserted in the rapid charger, the green control lamp 

fl ashes to indicate that the battery is charging. The green light stops fl ashing 

and remains on to signal that the battery is fully charged. If the red control lamp 

fl ashes, the battery is defective. If the red control lamp comes on and remains 

on, this indicates that the temperature of the rapid charger and / or the battery 

is outside the permissible operating range of the rapid charger of 0°C to +40°C.

NOTICE

The rapid chargers are not suitable for outdoor use.

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 (14) right in, if necessary turning them until 

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

pressing device clean.

2.4.  Assembly (changing) of the expander (15), the expanding head (16) on 

ROLLER’S Akku-Exparo 22 V ACC (Fig. 10)

Choose an expander (15) to match the expanding head (16). 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-CEF expanding 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 (18) 

lightly. 
Changing the P and Cu expander

Screw the selected expanding head onto the expanding device (18) to the 

stop. The expanding device must now be set so that the thrust of the drive 

machine is taken up by the drive machine and not the expanding head at the 

end of the expanding. Unscrew the expanding device (15) complete with 

screwed on expanding head from the drive machine for this. Let the feed 

piston run forward as far as possible without the machine switching into 

reverse. In this position the expander with screwed-on expanding head must 

be screwed onto the drive unit until the expanding jaws (17) of the expanding 

head (16) are fully open. The expanding head must be secured with the 

locking nut (24) in this position.

NOTICE

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

head (16) in the expanding process because otherwise the expanding jaws 

(17) can bend or break.
Changing the P-CEF expander

Remove the battery. Screw on the locking nut (24) and the selected expander 

(15) up to the stop. Screw the selected expanding head (16) onto the expander 

up to the stop.

The pressing tongs, M

adapter tongs, especially the pressing contour (11, 22) of the pressing jaws 

(10) or all 3 pressing segments (21) must be checked for damage and wear 

before every use. Damaged or worn pressing tongs, Mini pressing tongs, 

pressing rings, adapter tongs and Mini adapter tongs may no longer be used. 

There is otherwise a risk of incorrect pressing or accidents.

A trial pressing with inserted press fi tting must be made with the drive unit and 

the respectively used pressing tongs, Mini pressing tongs and the respectively 

used pressing ring with adapter tongs or Mini adapter tongs before every use. 

The pressing tongs, Mini pressing tongs (1), the pressing ring (20) with adapter 

tongs or Mini adapter tongs must fi t into the drive unit mechanically and be 

properly lockable. After completing the pressing, check that the pressing jaws 

(10) close fully at “A” for the pressing tongs, Mini pressing tongs (Fig. 1), the 

(PR-3B) pressing ring (Fig. 18) and the 45° (PR-2B) pressing ring (Fig. 19). 

After completing the pressing, check that the pressing jaws (10) close fully at 

“A” and on the opposite side “B” for the (4G) pressing tongs (Fig. 15) and the 

(S) pressing tongs (Fig. 16). After completing the pressing, check that the 

pressing segments (21) close fully at “A” and on the opposite side “B” for the 

(PR-3S) pressing ring (Fig. 17) and the XL (PR-3S) pressing ring. Check the 

tightness of the connection (observe national specifi cations, standards, regula-

tions, etc.)

If during closing of the pressing tongs, pressing tongs Mini or pressing rings a 

marked ridge is created on the compression sleeve, the pressing may be 

defective or not tight (see 5. Trouble).
