Assembly
Mounting the Protective Devices
General Information
 Disconnect the power supply before making any ad-
justments, changing accessories, or placing the ma-
chine aside. This safety measure prevents accidental
starting of the power tool.
Note: After breakage of the grinding disc during operation or
damage to the holding fixtures on the protection guard/power
tool, the machine must promptly be sent to an after-sales ser-
vice agent for maintenance. For addresses, see section "Af-
ter-sales Service and Application Service".
 Adjust protection guards in such a manner that spark-
ing toward the operator is prevented.
Note: The encoding keys of the protection guards ensure that
only a protection guard that fits the machine type can be
mounted.
