Maintenance And Cleaning - Bosch GSB 90-2 E Professional Originalbetriebsanleitung

Sharpening Drill Bits
For drilling in metal, use only perfectly sharpened
HSS drill bits. The appropriate quality is guaran-
teed by the Bosch accessories program.
Twist drills from 2.5–10 mm can easily be sharp-
ened with the drill bit sharpener (see accesso-
ries).
Drill Stand
We recommend the use of a drill stand (see ac-
cessories) for work where greater precision is
particularly required.
Machine Vice
The machine vice, which is available as an ac-
cessory, enables secure clamping of workpieces.
This prevents the workpiece from turning and any
accidents this would cause.

Maintenance and Cleaning

Before any work on the machine itself, pull the
mains plug.
For safe and proper working, always keep the
machine and its ventilation slots clean.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an authorized after-sales
service agent for Bosch power tools.
In all correspondence and spare parts orders,
please always include the 10-digit article number
given on the nameplate of the machine.
WARNING! Important instructions for con-
necting a new 3-pin plug to the 2-wire cable.
The wires in the cable are coloured according to
the following code:
strain relief
live = brown
neutral = blue
Do not connect the blue or brown wire to the
earth terminal of the plug.
Important: If for any reason the moulded plug is
removed from the cable of this machine, it must
be disposed of safely.
