Overhaul
Have your power tool serviced by a qualified repair person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
Service must only be carried out by qualified personnel who have access to the Service instruction and/or
have been trained for service on this tool.
The electric motor is a sealed unit and may under no circumstances be opened by anyone else than Atlas
Copco Industrial Technique AB.
If it is judged that the electric motor is defect or in need of service, the complete motor unit should be re-
turned to Atlas Copco Industrial Technique AB for exchange.
Motors which have been opened by anyone else than Atlas Copco Industrial Technique AB will not be ser-
viced.
Overhaul and preventive maintenance is recommended at regular intervals once per year, after maximum
6.000.000 pulses, depending on which occurs first. More frequent overhaul may be needed if the machine
is used in heavy-duty operations. If the machine is not working properly, it should immediately be taken
away for inspection.
When dismantling the tool always use the specially designed service tool(s) recommended in the Spare
Parts section on ServAid - https://servaid.atlascopco.com.
Assembling the Pulse Unit
Make sure to assemble all parts of the Pulse unit in the right order.
It is important that the camshaft and the separator washer pin is lined up with the groove in the cylinder
front piece. If not, the cylinder end piece will not be correctly fastened, and the Pulse unit will not function
properly.
