Maintenance
General
It is recommended to regularly submit the tool to maintenance, or as soon as the hammer mechanism
gets weak, or when the carbon brushes switch off. When carrying out maintenance all parts of the main-
tenance set must be exchanged. Use the respective maintenance set provided for each machine.
Cleaning
Clean all parts – with the exception of the electrical parts – with cold cleaning agent.
Caution!
No clean-
ing agent should penetrate into the bearing. Clean the electrical parts with a dry brush.
Check for wear
Check the disassembled parts for wear (visual inspection) and replace worn parts.
Electrical tests
Before reassembling, perform an electrical test on all relevant parts (see chapter Electrical and Me-
chanical Test Instructions).
