WARNING:
When using a
•
wheel/Multi-disc, flex wheel or wire wheel brush,
the wheel guard must be fitted on the tool so that
the closed side of the guard always points toward
the operator.
When using an abrasive cut-off / diamond wheel,
•
be sure to use only the special wheel guard
designed for use with cut-off wheels. (In European
countries, when using a diamond wheel, the
ordinary guard can be used.)

•
work.
