The oscillation emission value is measured pursuant to
the applicable regulations and is suitable for comparing
the machine with other electrical tools, also refer to
Ä ‘Regulations from section: Technical data’ on page 6.
When using the Press Booster, the actual value depends
on which press machine (machine type) is used.
Combined with the Pressgun 5, the oscillation emission
value is for example < 2.5 m/s2.
2.3.3 Operating mode
Combined with a Viega system press machine, the Press Booster acts
as a press capacity booster.
As a rule, the Press Booster needs two pressings of the driving press
machine to execute a complete pressing for Megapress XL press con‐
nectors.
During the first pressing, the press machine moves the roller head of the
Press Booster forward and presses the ball heads of the hinged adapter
jaw into the contact points of the press ring, building up pressure. A
second pressing following directly after the first completes the pressing
process, and causes the press machine and the Press Booster to move
back automatically.
For the next pressing, you may need to carry out a a reset stroke to
move the press machine and the Pressgun-Press Booster back to its
starting position.
Once the Press Booster opens automatically, the pressing
has been completed properly. If you cannot fully open the
hinged adapter jaw of the Press Booster via the handle
after completed pressing and removal from the press ring,
actuate the press machine once more and carry out a
reset stroke; also refer to Ä Chapter 3.3 ‘Pressing’
on page 12.
As soon as the first pressing is completed, locking takes
place and prevents a separation of the Press Booster
from the press ring until the entire pressing process is ter‐
minated.
If you nevertheless need to interrupt the pressing, see
Ä Chapter 3.4 ‘Interrupting pressing’ on page 15.

3.2 Preparing the press tool
▶Remove the retaining bolt of the press machine (1).
▶Slide the Press Booster in via the press jaw fixture (2).
▶Slide the retaining bolt of the press machine in as far as it will go.
The shoulder strap simplifies working at heights, when you need to lay
down the press tool repeatedly to carry out other steps (such as placing
or shifting the press ring).

Using the shoulder strap
Handling
Pressgun Press Booster PT2 10

Use the additional securing strap comprised in the delivery for fastening
the shoulder strap to the press machine. Fastening the shoulder strap to
the press machine and to the Press Booster ensures a safe carrying
position and an optimal, ergonomic posture.
NOTICE!
Make sure that the securing strap does not slip. Always
pull the securing strap tight.

▶Use clasps to fasten the strap ends to the Press Booster and the
press machine.
▶Use the shoulder strap to sling the press tool over your shoulder.
▷In this position, you can safely carry the press tool.
3.3 Pressing
CAUTION!
Risk of crushing
Risk of getting your fingers and hands crushed.
nHold the press tool during pressing with both hands at
the handle areas provided for this purpose.
NOTICE!
Clamping the press tool
In case of pressing without press ring, the Pressgun-Press
Booster may jam.
nNever carry out pressings without press ring.
NOTICE!
Property damage due to defective press ring
Using a defectively, incorrectly dimensioned, or worn
press ring may result in incorrect pressing.
nCheck the press rings before use for any visible defect.
nOnly use press rings that are free of defects and of the
appropriate size.
Handling
Pressgun Press Booster PT2 12

Also observe the instruction for use of the press machine
and the Megapress XL piping system you are using.
Requirements:
nThe dimensions of the press connector match the dimensions of the
press ring.
▶Open the press ring and place it around the respective pressing
point of the press connector.
▶Pull the handle at the hinged adapter jaw back.
▷The hinged adapter jaw opens.
Handling
Pressgun Press Booster PT2 13

▶Move the open hinged adapter jaw to the press ring.
▶Insert the ball heads of the hinged adapter jaw into the contact
points of the press ring.
NOTICE! Make sure the ball heads sit correctly in the con‐
tact points of the press ring.
▶Push the handle forward.
▷The hinged adapter jaw closes.
▶Align the Press Booster so that safe footing is ensured during
pressing.
▶Carry out the first pressing with the press machine.
INFO! As soon as the first pressing is completed, locking
takes place and prevents a separation of the Press Booster
from the press ring. If you nevertheless need to interrupt the
pressing, see Ä Chapter 3.4 ‘Interrupting pressing’
on page 15.
▶Immediately after that, carry out the second pressing with the press
machine.
▷You have pressed the Megapress XL press connector to the
steel pipe.
The lock of the Pressgun-Press Booster opens automatically.
If the pressing is not completed after two press strokes
with the press machine and the Press Booster does not
open automatically, carry out another press stroke. Failure
of the Press Booster to open automatically may be a sign
that maintenance is due, see Ä Chapter 3.6 ‘Care and
maintenance’ on page 17.

▶Open the hinged adapter jaw via the handle and pull the Press
Booster off the press ring.
INFO! If you cannot fully open the hinged adapter jaw of the
Press Booster via the handle, carry out another stroke with
the press machine (reset stroke). After a brief startup of the
press machine, the press machine and the Press Booster
return to their starting positions.
3.4 Interrupting pressing
Should it be impossible to fully complete the pressing, you can manually
loosen the Press Booster from the press ring.
▶Keep the button for manual unlocking pressed until the piston has
fully retracted and the hinged adapter jaw is without any load.
INFO! To do so, you may need to reset the press machine
in the same way.
▶Pull the handle at the hinged adapter jaw back.
▷The hinged adapter jaw opens.
Aborted pressings of Megapress XL press connectors can be resumed
and completed later. This should only be done in exceptional cases and
is applicable in cases where the pressing was interrupted between the
first and second pressing, and the press ring was loosened manually.
Take the Press Booster off the press ring
Continuing an aborted pressing
Handling
Pressgun Press Booster PT2 15

Before and during the first press stroke of the resumed
pressing, note that the empty stroke is longer, and in par‐
ticular note the following:
nThe ball heads of the hinged adapter jaw must lie cor‐
rectly in the contact points of the press ring.
nThe press ring must not be inclined to the side and
must not touch the press connector.
Requirements:
nThe press connector and the press tool are not damaged.
▶Once more attach the press ring to the press connector.
INFO! When completing a pressing later on, it is not neces‐
sary to place the press ring in exactly the same position on
the press connector as during the aborted pressing, pro‐
vided the axial positioning of the press ring on the con‐
nector is correct the press ring sits at a right angle to the
pipeline axis.
▶Carry out the complete pressing with the Press Booster.
3.5 Troubleshooting
In case of malfunction, check the following potential causes:
