Pay attention to the direction of rotation. Al-
ways hold the machine so that sparks and
grinding dust fly away from the body.
When grinding metal, flying sparks are pro-
duced. Take care that no persons are endan-
gered. Due to danger of fire, no combustible
materials should be located in the vicinity
(spark flight zone).
Always switch off the machine and allow to
come to a stop before placing it down.
Caution! The grinding tool runs on after the ma-
chine is switched off.
Bosch is only able to ensure perfect functioning
of the machine if the original accessories in-
tended for it are used.

Electrical Connection

The voltage and frequency of the power
source must agree with those given on the
nameplate of the machine.
In extreme working conditions, conductive
dust can accumulate in the interior of the
machine when working with metal. The pro-
tective insulation of the machine can be de-
graded. The use of a stationary extraction
system is recommended in such cases as
well as frequently blowing out the ventila-
tion slots and installing a residual current
device (RCD).
The machine may be connected only to
properly earthed mains. The socket and ex-
tension cable must have a functional pro-
tective conductor.
Attaching the Plug
For operating the HF power tools, a frequency
converter is required that generates three-phase
current with a frequency of 200 or 300 Hz.
Frequency converters are available in various
sizes with different frequencies, secondary volt-
ages and power ratings. The selection of the con-
verter is dependent on the machine to be con-
nected.
The machine is delivered with a special, four me-
tre long cable without plug.
A four-pole CEE plug (16 A capacity) with the
identifying colour of green is necessary. The pro-
tective contact socket must be in the 10 o'clock
position.
The plug must be mounted by a qualified electri-
cian according to the illustration. The contacts are
arranged according to DIN 49 462/63.

Determine the Direction of Rotation
The rotational direction of the tool must agree with
the arrow on the machine head. If the tool rotates
in the wrong direction when first put into opera-
tion, two phases in the plug must be inter-
changed.
For the wrong direction of rotation, the
tool will loosen itself from the grinder
spindle.
Mounting the Grinding Tools
(Optional Accessories)
Before any work on the machine itself, pull
the mains plug.
Use only grinding tools with a permissible
speed at least as high as the no-load speed
of the machine.
Clean the parts to be mounted. Hold the
grinder spindle 3 on the spanner surfaces
with a 17 mm open-ended spanner.
A B Loosen the collet chuck 4 or the clamping
nut 5 with a spanner.
Insert the clamping shaft of the grinding tool to the
stop into the collet chuck.
Tighten the collet chuck 4 or the clamping nut 5.
Type 0 602 245 ...
C Hold the grinding spindle 3 across the flats
using an open-end wrench, size 17 mm. Screw
on grinding accessory and tighten.
The female thread of the grinding tool must be
deeper than the length of the grinding spindle.
The grinding spindle must not run against the bot-
tom of the grinding accessory hole.
