Practical Advice
Always wait until the power tool has come to a complete stop before placing it
u
down.
The material removal rate and the sanding result are primarily determined by the choice
of sanding sheet and the contact pressure.
Only immaculate sanding sheets achieve good sanding performance and make the power
tool last longer.
Be sure to apply consistent contact pressure in order to increase the lifetime of the sand-
ing sheets.
Excessively increasing the contact pressure will not lead to increased sanding perform-
ance, rather it will cause more severe wear of the power tool and of the sanding sheet.
Do not use a sanding sheet for other materials after it has been used to work on metal.
Use only original Bosch-sanding accessories.
Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be overloaded. If the power tool is
overloaded or the permitted battery temperature is exceeded, the electronics of the
power tool will switch off until the temperature returns to within the optimum operating
temperature range.
