10.2 Tool repair

NOTE
If your tool is damaged, only have it repaired by the Hilti
Service Team.
Check all external parts of the tool for damage at regular
intervals and check that all controls operate faultlessly.
Do not operate the tool if parts are damaged or when the
controls do not function faultlessly.
10.3 Cleaning the tool 11
NOTE
The tool must be cleaned and serviced regularly. The tool
should be cleaned if you notice an increase in malfunc-
tions such as ignition faults. We recommend that the tool
be cleaned after no more than around 40,000 fastening
operations.
You can arrange for Hilti to carry out the required servicing
work for you. To do so, contact your local Hilti Center or
sales and service office.
Alternatively, you can carry out the cleaning yourself.
The required materials, tools, and documentation are
available from Hilti as accessories. Use only Hilti products
or products of equivalent quality to clean the tool.
