Fitting
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Fitting Protective Equipment
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Adjust the protective guard (2) such that sparking in
u
the direction of the operator is prevented.
Protective guard for grinding (see figure A)
Place the protective guard (2) on the spindle collar. Adjust
the position of the protective guard (2) to meet the require-
ments of the operation. Lock the protective guard (2) with
the locking screw (9) and tighten the locking screw with at
least 10 Nm.
Fitting the abrasive tools (see figure B)
The grinding tools must run completely concentrically. Do
not continue to use damaged grinding tools that are out of
balance. If the grinding tools are out of balance, they should
be replaced or dressed with a whetstone (accessory).
The whetstone can also be used to mould the basic grinding
tool shapes into any number of special shapes. When using
grinding tools with a threaded insert, make sure that the end
of the grinding spindle (3) does not come into contact with
the grinding tool's perforated plate.
– Turn the grinding spindle (3) until the hole in the grinding
spindle (3) and the recesses on the housing are aligned.
Insert the holding rod (10) through the recesses on the
housing and the hole in the grinding spindle (3).
– Loosen the clamping nut (1) with the supplied two-pin
spanner (11) and remove the nut.
– Clean the grinding spindle (3) and all the parts to be fit-
ted.
– Position the grinding tool and tighten the clamping
nut (1) with the two-pin spanner (11). Make sure that the
grinding tool can rotate freely in the protective guard (2).
Only use conical grinding tools with the open protect-
u
ive guard (2) and the appropriate clamping system
(clamping nut (1) or quick-clamping nut (7) and
mounting flange (4)).
Changing the Mounting Flange (see figure C)
Use the mounting flange (4), the clamping nut (1) and the
open protective guard (2) to secure conical grinding tools.
Lever the spring ring (13) out of the grinding spindle (3)
groove with a screwdriver and remove the mounting
flange (4). Fit the suitable mounting flange (4) accordingly.

Quick-Clamping Nut
To change the abrasive tool easily without having to use any
additional tools, you can use the quick-clamping nut (7) in-
stead of the clamping nut (1).
The quick-clamping nut (7) must not be used for
u
brushes.
Only use quick-clamping nuts that are in good working
order and not damaged (7).
When screwing on, make sure that the printed side of the
quick-clamping nut (7) is not facing the grinding disc; the
arrow must be pointing towards the index mark (12).
Turn the grinding spindle (3) until the hole in the grinding
spindle (3) and the recesses on the housing are aligned. In-
sert the holding rod (10) through the recesses on the hous-
ing and the hole in the grinding spindle (3). To tighten the
quick-clamping nut (7), turn the grinding disc firmly clock-
wise.
If the quick-clamping nut has been attached correctly and is
not damaged, you can loosen it by hand by turning the
knurled ring anticlockwise. Never loosen a tight quick-
clamping nut with pliers. Always use the two-pin
spanner (11).
Dust/Chip Extraction
Dust from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the ma-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Operation
Starting operation
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
Switching On and Off
To start the power tool, first slide the on/off switch (6) to
the front, then press and hold it.
