M7 QD221 Gebrauchsanweisung

Read this manual carefully before installing, operating,
servicing or repairing.
Working environment:
1.Using these tools in any potentially explosive environment is strictly prohibited.
2.It is always recommended that these types of tools must be operated when standing
on a solid or firm location.
3.Always use these tools in a well ventilated area.
4.Slipping, stumbling and falling are the major causes of potential serious injury,
therefore, a clean and clutter free surface in the working area before operating the
tools is strongly recommended.
Air supply and connection requirements:
1.The maximum recommended air pressure during operation must not exceed 90 psi
(6.3bar). Higher air pressure may create unsafe operating conditions for the tool and
the user.
2.The compressed air should be cooled and have a water filter installed at the outlet
end of the compressor. Even with a water filter installed, some water may still
condense in the piping or hose and will enter the tool mechanism causing premature
damage to the tool. Therefore, it is recommended to install an air filter-lubricator
device somewhere between the tool and the compressor.
3.Always use an air compressor of the proper capacity to operate each tool.
4.Clean the hose with a blast of compressed air before connecting the hose to the air
tool. This will prevent both moisture and dust inside the hose from entering the tool
and causing possible rust or malfunction.
