Unscrew the three screws on the upper part of the housing
(10) and remove the housing towards the back.
Remove oil reservoir screw plug (A) and replace with the air
filter provided.
As a precaution, push the notch lever (B) of the overload
relay (C) through as far as the end stop; it could have been
loosened by the transport.
Reattach the housing.
Connect the plug of the safety foot-operated switch (12) to
the flange socket (1) on the device.
Connect the control cable of the pistol to the flange socket (2) on the device and secure by
pressing and turning.
Connect the hydraulic hose of the pistol to the device with the aid of the quick coupling (11)
and connect the power cable to the power supply.
The hydraulic system is now ready for operation.
The device should only be operated at the voltage stated on the type plate! The
power supply should be protected by a 10 A fuse!
In case of overloading of the device, the overload relay (C) switches off automatically and the
fault indicator lamp (8) lights up.
Disconnect the mains plug and remove the housing (10) as described above.
Push the notch lever (B) through as far as the end stop and re-connect the power cable to
the power supply.

Adjusting the hydraulic pistols H 1 and H 2
Checking the preadjustment:
Screw the expander head which is to be used onto the hydraulic pistol as far as the end
stop.
The segments of the expander head must not be expanded in the retracted state. The adjusting
nut of the pistol, which regulates the extension and retraction of the expanding mandrel, can be
adjusted using the adjusting spanner.
Unscrew the expander head again.
Adjusting:
Turn operating switch (4) to ON and adjust operating pressure to 80 bar using rotary knob
(9).
Turn switch (5) to setting up mode and operate foot-operated switch (12).
Always hold the foot-operated switch depressed during the working cycle!
Press the microswitch on the hydraulic pistol momentarily, so that the expanding mandrel
travels to the front as far as the end stop (ill. 1).
The device switches off automatically on reaching the set pressure!
Screw the expander head tightly onto the pistol and release the foot-operated switch (12) to
relieve the pressure again (expansion piston returns to the initial position again) (ill. 2).
The expander head is adjusted correctly if it can be turned another 1/3 – ½ of a rotation to
the right as far as the end stop (ill. 3).
Always carry out an experimental expansion to determine whether the required
expansion diameter has been achieved. Correct any deviations using the adjusting
spanner on the adjusting nut of the pistol!
If the appropriate expander head (as described above) has been adjusted correctly, turn the
switch (5) to "AUTOMATIC".
Push the pipe over the expander head and press the foot-operated switch momentarily.
