Wire Brush (Wheels And Cups); Maintenance; Service; Tool Lubrication - Bosch GWX13-50 Operating/Safety Instructions Manual

▶ Wire Brush (Wheels and Cups)

Wire brushes are intended to "clean"
structural steel, castings, sheet metal,
stone, and concrete. They are used to re-
move rust, scale, and paint.
1. Allow the tool to reach full speed be-
fore touching the tool to the work sur-
face.
2. Apply minimum pressure to the work
surface, allowing the tool to operate at
high speed.
3. Continuously move the tool at a moder-
ate speed to avoid creating gouges in
the work surface.
4. Remove the tool from work surface be-
fore turning tool off. Allow the tool to
stop rotating before laying it down.
Tip: The tips of the brush do the work.
Operate wire brushes with the lightest
pressure so only the tips of the wire come
in contact with the work piece. If heavier
pressures are used, the wires will be over-
stressed, resulting in a wiping action and
a shortened brush life due to wire fatigue.
Applying the side or edge of the brush to
the work piece will result in wire breakage
and shortened brush life.
adjustments, changing accessories, or storing power tools. Such preventive safety
measures reduce the risk of starting the power tool accidentally.
