Adjusting the Speed (GBM 23-2 E)
The speed of the switched on power tool can be
variably adjusted, depending on how far the
On/Off switch 6 is pressed.
Light pressure on the On/Off switch 6 results in
a low rotational speed. Further pressure on the
switch results in an increase in speed.

Working Instructions

Use drilling lubricant or cutting oil for cooling
and lubrication, and to avoid overheating or jam-
ming of the drill bit.
When drilling diameters > 10 mm, drill a pilot
hole with a small drilling diameter. This allows
you to reduce the feed pressure and the power
tool is strained less.
For drilling in metal, use only perfectly sharp-
ened HSS drill bits (HSS = High Speed Steel).
The appropriate quality is guaranteed by the
Bosch accessories program.
The machine vice, which is available as an acces-
sory, enables secure clamping of workpieces.
This prevents the workpiece from turning and
any accidents this would cause.

Maintenance and Service

Maintenance and Cleaning

Before any work on the power tool itself,
pull the mains plug.
For safe and proper working, always keep
the power tool and the ventilation slots
clean.
If the power tool should fail despite the care tak-
en in manufacturing and testing procedures, re-
pair should be carried out by an after-sales ser-
vice center for Bosch power tools.
In all correspondence and spare parts orders,
please always include the 10-digit article number
given on the type plate of the power tool.
