MAINTENANCE
Irrespective of the above maintenance work, all the machines must be returned together with all
tools at least once a year for inspection.
Maintenance
Before maintenance work, pull the mains plug or remove the battery.
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.
a)
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.
b) 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.
Inspection/repair
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.
