GENERAL INFORMATION
Although we recommend that the repairs have to be carried out only by authorized DOA service

brass punch, a vice with soft protection for the jaws, a clean container for collecting the tool

•
Control that the tool is complete and that all parts and fastenings are in their place and well
installed.
•
Check that the control and starting devices, in particular the safety devices and protections,
are efficient, without deformations and in their original state. If they have been modified or
repaired adapting them, discard them and order new parts.
•
If a safety or warning sticker is damaged, illegible or missing, order new parts checking the
part number on the tool part list.
•
Control the tool accessories (bits – cut-off discs – hoses, etc.) to be sure that they are of the
right type, oriented in the right way and they are not the cause of the problems.
•
Control the quick couplers on the tool and on the flexible hoses, make sure they are correctly
installed, that they can be connected in the right way to assure the right oil direction.
