the pressing contour and a number to identify the size. Consult and comply with the instruc-
tions for installation and fitting of the system's manufacturers. Never use non-matching pressing
tongs for pressing work. The press joint could be unserviceable, and both the machine and the
pressing tongs might be damaged.
The drive unit is best placed on a bench or the floor. Installing the pressing tongs is only pos-
sible when the press rollers in are fully retracted. If necessary, set the rotation direction lever to
the left and operate the inching switch, and press the reset button until the press rollers are fully
retracted.
Open the tongs shank. To do so, press the locking pin, the tongs shank jumps out under
spring loading. Insert selected pressing tongs. Push home the tongs shank until the locking pin
engages. While doing so, press down the pressure tongs inserted. Do not start the pressing
operation except to make a press joint. Unless counter pressure is applied by the press fitting,
the drive unit or pressing tongs will be needlessly stressed.
Never operate press when the tongs shank is not locked. Risk of fracture.
Radial presses
Before use, always perform a trial pressing with the drive unit and the pressing tong inserted,
with fitting in place. The pressing tongs must close completely. Complete closing of the pressing
jaws both at their tips and at the level of the connecting link must be observed after completion
of pressing. The tightness of the connection must be checked (country-specific regulations,
standards, guidelines etc. must be followed).
Before use, always check the pressing tongs, in particular the pressing contour of both pres-
sing jaws, for damage or wear. Do not use damaged or worn pressing tongs again. Otherwise
there is a risk of correct pressing or accidents.
If during closing of the pressing tongs a marked ridge is created on the compression sleeve,
the pressing may be detective or not tight.
Working procedure
Press the pressing tongs together manually until they can be pushed over the press fitting.
Always position the drive unit with the pressing tongs on the press fitting at right angles to the
pipe axis. Release the pressing tongs so that they close around the press fitting. Hold the drive
unit by the housing grip and the pistol grip.
In the case of the Pressmatic Portable CCA and Pressmatic CCA, hold down the inching
switch until the pressing tongs are completely closed. After completion of pressing, the drive unit
switches automatically to return (forced return).
Press the pressing tongs together manually so that they can be removed from the press
fitting.
Operating safety
These tools end the pressing operation automatically, emitting an acoustic signal, and return
automatically.
Important: Only complete closing of the pressing tongs provides a perfect press joint.
Complete closing of the pressing jaws both al their tips and al the level of the connec-
ting link must be observed after completion of pressing. If during closing of the pressing
tongs a marked ridge is created on the compression sleeve, the pressing may be defecti-
ve or not tight.
