3.2.1

Putting into operation

Please read through the operating instructions and safety instructions attentively
before you put the butt fusion welding machine into operation!
Do not use the heating element in explosive environments or bring it into contact
with easily flammable materials!
Stay a safe distance away from the machine. Do not stand or reach into the ma-
chine. Keep other people away from the work area!
Before every start-up, check the oil level of the hydraulic unit. The oil level must be
between the min. and max. marking on dipstick in the oil filler cap. If necessary, add
HLP 46 hydraulic oil!
Transport and set the hydraulic unit only in a horizontal position. If it is set at an
angle, oil escapes from the vented plugs with the dipstick!
 Connect the hydraulic unit to the basic unit with both hydraulic hoses.
Protect the quick couplings from contamination. Replace leaky couplings immediately!
 Connect the trimmer unit, hydraulic unit and heating plate mains plugs to the power out-
let/supply specified on the type plates.
For P160-250B:
 The red "Stand by" diode on the heating element lights up, which means: voltage is being
applied. Switch on the heating element on the hand grip using the large press-button (lights
up green) and set the desired temperature using the "+" or "-" button (160°C to 285°C /
320°F to 545°F).
Heating is displayed on the hand grip by the yellow diode. Horizontal bars also appear on the
temperature indicator. The yellow diode goes out shortly before reaching the set nominal tem-
perature (tolerance +/-3°C / 5.4°F) and the green one lights up. The heating element is usable
after a further 10 minutes. Note: upon first reaching the nominal temperature the set value can
be exceeded for short time.
 Check the temperature using an external temperature measuring instrument. If there are de-
viations it means that the heating element must be re-calibrated: press the "+" and "-" button
simultaneously and then set the difference using the "+" or "-" button.
If "Er1" appears this means the electronics are defective. For "Er2" the resistance thermometer
is either defective or not connected. Send the device to an authorised ROTHENBERGER speci-
alist workshop.
Risk of serious injury! The heating plate can reach temperatures of over 290°C /
554°F! We highly recommend storing the heating plate in the designated carrying
frame immediately after use!
For P355B:
 Turn on the main switch of the control box. The switch lights up green and the actual tem-
perature of the hotplate is shown on the display. Use the – and + keys to set the desired
temperature between 160°C and 270°C / 320°F and 518°F.
