Fitting Abrasive Tools Using Two Open-Ended
Spanners (see figure B)
Only use open-ended spanners that are suitable and
u
undamaged (see "Technical Data").
– Clean the grinding spindle (3) and all the parts to be fit-
ted.
– Use an open-ended spanner (8) on the spanner flat of the
grinder spindle (3) to hold it in place.
Loosen the clamping nut (2) by placing an open-ended
spanner (9) on the spanner flat and turning it counter-
clockwise.
– Insert the straight shank of the grinding tool all the way
into the collet (1).
– Hold the grinding spindle (3) with the open-ended span-
ner (8) and tighten the application tool by placing the
open-ended spanner (9) on the spanner flat and turning it
clockwise.
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.
Do not, under any circumstances, tighten the collet
u
with the clamping nut until a grinding tool has been
fitted. The collet may otherwise become damaged.
Only use mounted points with an appropriate shank
u
diameter. A mounting point with a shank diameter which
does not correspond to the tool holder of the power tool
(see "Technical data") cannot be held properly and will
damage the collet chuck.
The application tool must be clamped at least 10 mm.

maximum permitted speed of the application tool from
the specifications provided by the manufacturer of the
application tool. It must not be less than the maximum
speed of the power tool.
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.
Check whether there is visible damage to the
u
collet (1) and clamping nut (2) before each use.
Switching On and Off
GGS 30 LS/GGS 30 S
To start the power tool, slide the on/off switch (5) forwards.
To lock the on/off switch (5) in position, push the on/off
switch (5) forwards and down until it clicks into place.
To switch off the power tool, release the on/off switch (5);
or, if the switch is locked, briefly push the on/off switch (5)
backwards and down and then release it.
Switching On and Off
GGS 30 LPS
To start the power tool, first slide the lock-off button (12)
to the rear, then press and hold the on/off switch (11).
To switch off the power tool, release the on/off switch (11).
Constant Electronic control
The Constant Electronic keeps the speed at no load and un-
der load virtually consistent, guaranteeing uniform perform-
ance.
Speed preselection
You can preselect the required speed using the speed
preselection thumbwheel (6), even during operation.
The required speed depends on the material being worked
and the diameter of the application tool. Observe the max-
imal allowable speed of the application tool.
GGS 30 LS/GGS 30 LPS
At maximum speed, the maximum permitted diameter of the
accessory is 40 mm.
GGS 30 S
At maximum speed, the maximum permitted diameter of the
accessory is 45 mm.
If you are using an accessory with a diameter of 50 mm,
make sure that the speed is not greater than 30000 min
