7. RE-PRESSING
Re-pressing is always necessary if pressing has not been fully completed. There are a few peculiarities
that must be observed for re-pressing, in contrast to pressing.
Ensure that the claws of the intermediate jaw enclasp the press collar pins during the re-pressing process.
During the re-pressing, the tool can be started, even though the claws are not enclasping the pins properly.
The tool is able to travel a large idle stroke as a result of the respective pre-pressing of the fitting.
Because the tool is not correctly secured and a change in position occurs during this phase, the claws my
no longer enclasp the collar pins properly.
Note!
The claws of the intermediate jaw may break as a result and the press-collar pins may become damaged.
Injury hazard!!!!

Clean the contacts (15) in the cylinder.
Clean the closed jaw sensor (17).
The contacts (15) and the jaw-closing sensor (17) must be free of grease and corrosion-protection agents.
Press jaw/intermediate jaw:
Regularly or when soiled:
• Remove deposits from pressing contour (K).
• Clean pressing contour (K) of press jaw using a solvent.
• Lubricate pins in press jaw/intermediate jaw with machine oil.
• Coat press jaw, intermediate jaw all over with a rust-inhibiting and anti-corrosion spray.
• Clean contacts (16) in press jaw.
Clean closed jaw sensor (17).
• The contacts (16) and the jaw-closing sensor (17) must be free of grease and corrosion-protection
agents.
Press collars:
Regularly and when soiled:
Press collars should be cleaned with compressed air.
Clean pressing contour (K) of press collars with a solvent (e.g. methylated spirit).
Coat pressing contour (K) all over with lubricant.
Apply rust and corrosion-inhibiting spray all over press collar.
