Assembly
 Disconnect the power supply before making any ad-
justments, changing accessories, or placing the ma-
chine aside. This safety measure prevents accidental
starting of the power tool.
Mounting of the Extension (see figure A)
(Type 0 602 238 ...)
Depending on the application, the grinder spindle can be ex-
tended up to 450 mm. For this purpose, extension with
150 mm (article number 3 606 120 031) and 300 mm (arti-
cle number 3 606 120 032) are available as an accessory.
 When working with an extension, the effective force on
the grinder spindle must not exceed 15 N (max.)! This
corresponds with a grinding-point load of 1.5 kg. Other-
wise, the grinder spindle can break.
Loosening the Grinder Spindle
– Heat up the spindle housing 5 in the area of the threaded
sleeve 8 to approx. 100 °C, e.g., using a hot air blow-
er/heat gun with temperature control. Unscrew the spindle
housing together with the grinder spindle using open-end
spanner 12 by turning in anticlockwise direction, while
counter-holding the spanner surfaces of the threaded
sleeve 8 with open-end spanner 10.
Inserting an Extension
– Apply a drop of the provided Loctite 241 to the thread of
the extension 9. Screw the thread of the extension into
grinder spindle 4 and tighten with 20 Nm.
– Pay attention that the toothing of the spindle is mounted
tension-free.
– When mounting an additional extension, also apply a drop
of Loctite 241 to the second extension and screw it onto
the first one.
Bosch Power Tools
– Afterwards, apply a drop of the provided Loctite 241 to
the thread of the threaded sleeve 8, screw on the exten-
sion and tighten with 20 Nm.
Mounting the Auxiliary Handle
Type 0 602 233 ... (see figure G)
The auxiliary handle 21 is not mounted upon delivery of the
power tool.
The auxiliary handle 21 consists of the tensioning strap 22,
handle 23, clamping holder 24 and screw 25.
– Mount the auxiliary handle before connecting the machine
to the power supply.
– Firstly, guide screw 25 through the opening of the clamp-
ing holder 24 and then with the clamping holder into the
handle 23.
– Screw the screw into the thread on the metal handle of the
tensioning strap 22. Mount the tensioning strap 22 via the
cable onto the housing of the power tool and bring the
handle into the right position.
– Tension the tensioning strap 22 around the housing by
tightening screw 25.
– Check if the auxiliary handle 21 is seated firmly on the
housing.
Changing the Tool
(Type 0 602 207 ..., 0 602 208 ..., 0 602 209 ...,
0 602 210 ..., 0 602 211 4.., 0 602 238 ...,
0 602 245 ...)
 Only use grinding points with a matching shank diame-
ter. A grinding point/accessory with a shank diameter that
does not fit the tool holder (see "Technical Data"), can not
be clamped properly and will damage the collet chuck.
 When inserting a grinding point/accessory, pay atten-
tion that its shank is seated tightly in the tool holder.
When the shank of the grinding point/accessory is not in-
serted deep enough into the tool holder, the grinding
point/accessory can slip out again and no longer be con-
trolled.
 Do not use cut-off discs and routing accessories. The
power tool does not have safety devices for these applica-
tion tools.
 The rated speed of the grinding point/accessory must
be at least equal to the maximum speed marked on the
power tool. Accessories running faster than their rated
speed can break apart and be thrown about.
 Use only grinding points/accessories that are in per-
fect condition and not worn. Defective grinding points/
accessories, as an example, can break apart and cause in-
juries or damage.
 After inspecting and installing the grinding point/ac-
cessory, position yourself and bystanders away from
the plane of the rotating grinding point/accessory and
run the power tool at maximum no-load speed for one
minute. Damaged grinding points/accessories will nor-
mally break apart during this test time.
