cedure and may be used to compare power tools. It can also
be used for a preliminary estimation of exposure to vibra-
tion.
The stated vibration level applies to the main applications of
the power tool. However, if the power tool is used for differ-
ent applications, with different application tools or poorly
maintained, the vibration level may differ. This can signific-
antly increase the exposure to vibration over the total work-
ing period.
To estimate the exposure to vibration accurately, the times
when the tool is switched off or when it is running but not ac-
tually being used should also be taken into account. This can
significantly reduce the exposure to vibration over the total
working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping the hands warm,
and organising workflows correctly.
Fitting
Pull the plug out of the socket before carrying out any
u
work on the power tool.
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.
Fitting the abrasive tools (see figure A)
(GGS 5000)
– Clean the grinding spindle (3) and all the parts to be fit-
ted.
– 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 (8) through the recesses on the
housing and the hole in the grinding spindle (3).
– Loosen the clamping nut (2) with the open-ended
spanner (9) (width across flats 17 mm) by turning it anti-
clockwise.
– Insert the straight shank of the grinding tool all the way
into the collet (1).
– Tighten the clamping nut (2) with the open-ended
spanner (9) (width across flats 17 mm) by 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.

– Clean the grinding spindle (3) and all the parts to be fit-
ted.
– Use an open-ended spanner (9) on the spanner flat of the
grinding 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 anticlock-
wise.
– Insert the straight shank of the grinding tool all the way
into the collet (1).
– Hold the grinding spindle (3) with the open-ended
spanner (9) and tighten the application tool by placing
the open-ended spanner (9) on the spanner flat and turn-
ing 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.
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.
Check whether there is visible damage to the
u
collet (1) and clamping nut (2) before each use.
