Maintenance And Cleaning; Practical Advice - Bosch GSB 22-2 RE Instrucciones De Servicio

Replacing the Drill Chuck
For machines without a drill spindle locking facil-
ity, the drill chuck must be changed by an author-
ised after-sales service shop for Bosch power
tools.
The drill chuck must be tightened with a
torque of approx. 35 – 40 Nm.
Vibration damper
The integrated vibration damper 4 reduces any
vibrations occurring particularly during impact
drilling.
The soft grip reduces any danger of slipping and
thereby ensures a better grip and handling of the
machine.

Practical Advice

Drilling Tiles
Push the selector switch 2 to the symbol "Drilling
and Driving". Do not switch over to the symbol
"Impact Drilling" or work with impact until after
drilling through the tile.
Sharpening Drill Bits
For drilling in metal, use only flawlessly sharp-
ened HSS drills. The appropriate quality is guar-
anteed by the Bosch accessories program.
Twist drills from 3.5 – 10 mm can easily be sharp-
ened with the drill sharpener (see Accessories).
Bench Stand
We recommend the use of a bench stand (see
Accessories) for work where greater precision is
particularly required.
Machine Vice
The machine vice can be obtained as an acces-
sory and clamps work pieces tightly for drilling.
This prevents the work piece 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 the 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 centre for Bosch power tools.
In all correspondence and spare parts orders,
please always include the 10-digit order 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.
