Assembly
Before any work on the machine itself, pull the mains
plug.
Mounting the Protective Devices
Adjust protection guards in such a manner that spark-
ing toward the operator is prevented.
Protection Guard for Grinding (GGS 8 SH) (see figure A)
Place the protection guard 2 on the spindle collar. Adapt the
position of the protection guard 2 to the requirements of the
work step. Lock the protection guard 2 with locking screw 13
and tighten the locking screw with at least 10 Nm.
Protection Guard for Grinding (GGS 8 H) (see figure E)
Place the protection guard 10 on the spindle collar. Adapt the
position of the protection guard 10 to the requirements of the
work step. Lock the protection guard 10 with the two locking
nuts 18 and tighten the locking nuts with at least 10 Nm.
After mounting the grinding tool, shut the protection guard 10
and tighten both wing nuts.
Mounting the Grinding Tools
The grinding tools must run completely concentrically. Do not
continue to use damaged grinding tools that are out of bal-
ance. If the grinding tools are out of balance they should be re-
placed. Treat with a whetstone (accessory) or change.
Using a whetstone, any particular special shape can be pro-
duced out of the basic forms of the grinding accessory.
When using grinding tools with a threaded insert, pay atten-
tion that the end of the grinder spindle 3 does not touch the
hole base of the grinding tool.
GGS 8 SH (see figure B)
– Turn the grinder spindle 3 until the hole in the grinder spin-
dle 3 and the openings of the housing are aligned. Insert
the holding rod 14 through the openings of the housing
and the hole of the grinder spindle 3.
– Loosen and remove the clamping nut 1 with the two-pin
spanner 15 provided.
– Clean the grinder spindle 3 and all parts to be mounted.
– Mount the grinding accessory and tighten clamping nut 1
with two-pin spanner 15. Pay attention that the grinding
accessory can rotate freely in protection guard 2.
Use tapered grinding accessories only in conjunction
with the open protection guard 2 and the matching
clamping system (clamping nut 1 or quick-clamping
nut 7 and mounting flange 4).
GGS 8 H (see figure F)
– Turn the grinder spindle 3 until the hole in the grinder spin-
dle 3 and the openings of the housing are aligned. Insert
the holding rod 14 through the openings of the housing
and the hole of the grinder spindle 3.
– Loosen the clamping nut 8 with the open-end spanner 19
(size 24 mm) by turning in anticlockwise direction.
– Remove the clamping flange 9.
– Clean the grinder spindle 3 and all parts to be mounted.
1 609 92A 46N | (20.12.17)
– Mount the grinding accessory and clamping flange 9 and
tighten clamping nut 8 with open-end spanner 19 (size
24 mm). Pay attention that the grinding accessory can ro-
tate freely in protection guard 10.
Use straight grinding accessories only in conjunction
with the enclosed protection guard 10 and the match-
ing clamping system (clamping nut 8, clamping flange
9 and mounting flange 11).
Changing the Mounting Flange (see figure D)
GGS 8 SH
To fasten tapered grinding accessories, use mounting flange
4, clamping nut 1 and the open protection guard 2.
Lever snap ring 17 out of the groove in grinder spindle 3 using
a screwdriver and remove mounting flange 4. Mount the fit-
ting mounting flange 4 analogously.
GGS 8 H
To fasten straight grinding accessories, use mounting flange
11, clamping nut 8, clamping flange 9 and the enclosed pro-
tection guard 10.
Lever snap ring 17 out of the groove in grinder spindle 3 using
a screwdriver and remove mounting flange 11. Mount the fit-
ting mounting flange 11 analogously.
Quick-clamping Nut
(see figure C)
For convenient changing of grinding tools without the use of
additional tools, you can use the quick-clamping nut 7 instead
of the clamping nut 1.
Quick-clamping nut 7 may not be used for brushing.
Use only a flawless, undamaged quick-clamping nut 7.
When screwing on, pay attention that the side of the
quick-clamping nut 7 with printing does not face the
grinding disc; the arrow must point to the index mark 16.
A properly attached, undamaged quick-clamping nut can be
loosened by hand when turning the knurled ring in anticlock-
wise direction. Never loosen a tight quick-clamping nut
with pliers. Always use the two-pin spanner 15.
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 car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining 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
materials to be worked.
Prevent dust accumulation at the workplace. Dust can
easily ignite.
