Keep the pressing tongs, pressing heads and expanding heads, and particularly their receptacles,
clean. Clean heavily soiled metal with turpentine oil and then rustproof them.
Clean plastic parts (housing, batteries) only with a mild soap and a damp cloth. Do not use domestic
cleaning agents. These frequently contain chemicals that can attack plastic parts. On no account use
petrol, turpentine oil, thinners or similar products to clean plastic parts.
Ensure that liquids never get inside the electrical equipment. Never immerse the electrical equipment in
liquid.
• Pressing tongs
Check the pressing tongs for easy action at regular intervals. If necessary clean the pressing tongs
and lubricate the bolts of the pressing jaws with machine oil, however do not dismantle the pressing jaw.
Remove any deposits in the pressing contour. Check that all pressing tongs are functional at regular
intervals by a trial pressing operation with the press fitting inserted. The pressing jaws must close both at
their tips and at the level of the connecting link after completion of pressing. Do not use damaged or worn
pressing tongs to an authorised after-sales service facility for inspection.
• Radial presses
Keep the press tongs receptacle clean, in particular clean the press rollers and tongs shank at regular
intervals and then lubricate them with machine oil. Check the functional reliability of the drive unit regularly
by marking a pressing with the largest press fitting used. If the pressing tongs close completely during this
pressing operation, the drive unit is functionally reliable.
Before any repair work, pull the mains plug or remove the battery. This work may only be performed by
authorised experts or by trained personnel.
After around 10.000 pressing/expanding operations, but a least once a year, inspection of the pressing/
expanding tool.
