The Press Booster increases pressing force. In combination with a Viega Pressgun 6 Plus (or comparable system press machines, see below) and the corresponding Viega Megapress XL system press rings, the Press Booster becomes a complete system press tool. The system press tool enables Megapress XL connectors to be pressed in sizes of 4 inches or 114.3 mm.
All of the functions of the Press Booster are certified.
Suitable system press machines:
Viega | Nussbaum |
|---|---|
Viega type II | Nussbaum type 2 |
Viega PT3-H | Nussbaum type 3 |
Viega PT3-EH | |
Viega Pressgun 4E | Nussbaum type 5 |
Viega Pressgun 4B | Nussbaum type 5A |

INFO!
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
Regulations from section: Technical data
. 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.
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 connectors.
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.
INFO!
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 Pressing .
INFO!
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 terminated.
If you nevertheless need to interrupt the pressing, see Interrupting pressing .
Handling
Transport and storage
Protect the Press Booster from the following external influences:
Impacts
Moisture and humidity
Dust and dirt
Frost and extreme heat
Chemical solutions and vapours
Clean the Press Booster and the press rings before switching them off for longer standstill or storage
Cleaning the press tools
.
Store the Press Booster and press rings only in the case comprised in the delivery.
Preparing the press tool
Placing the Press Booster on the press machine
-
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.
Using the shoulder strap
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).
Depending on the press machine used, the shoulder belt can be attached directly to the existing fixing points on the press machine (e.g. Pressgun 6 Plus) or by using the accompanying additional securing strap. 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.
The following pictures show the exact position for fastening the securing strap for each suitable press machine type:
- 1 Viega PT2
- 2 Viega PT3-H / Viega PT3-EH
- 3 Viega Pressgun 4B
- 4 Viega Pressgun 4E
- 5 Viega Pressgun 5
-
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.
Pressing
CAUTION!
Risk of crushing
Risk of getting your fingers and hands crushed.
Hold 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.
Never 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.
Check the press rings before use for any visible defect.
Only use press rings that are free of defects and of the appropriate size.
INFO!
Also observe the instruction for use of the press machine and the Megapress XL piping system you are using.
Requirements:
The 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.
-
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 contact 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 Interrupting pressing .
-
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.
INFO!
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 Inspection and maintenance .
-
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.
Interrupting pressing
Take the Press Booster off the press ring
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.
Continuing an aborted pressing
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.
INFO!
Before and during the first press stroke of the resumed pressing, note that the empty stroke is longer, and in particular note the following:
The ball heads of the hinged adapter jaw must lie correctly in the contact points of the press ring.
The press ring must not be inclined to the side and must not touch the press connector.
Requirements:
The 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 necessary to place the press ring in exactly the same position on the press connector as during the aborted pressing, provided the axial positioning of the press ring on the connector is correct the press ring sits at a right angle to the pipeline axis.
-
Carry out the complete pressing with the Press Booster.
