Safety elements assembly
WARNING
Risk of accident, electric shock
Always pull the plug out of the socket before
performing any type of work on the machine.
CAUTION
Always use the additional handle to guarantee
a safe, non-tiring working posture.
7.1 Additional
holder
Special construction “VIBRASTOP” regulates the
vibrations with additional holder
[1-14]
. Addition-
al holder can be screwed from the left or right
side of gearbox.
7.2 Exhaust
cover
Assembly
Before inserting the machine into the cover,
we recommend you to turn the machine case
by 180° with respect to the gearbox so that the
switch is on the right hand side.
Arrest the exhaust cover in the top position and
put in on the side, with the clamping sleeve
up. Then put the clamping neck
[3-1]
of the
grinder into the sleeve. Put the guiding tabs
[3-2]
into the grooves on the clamping neck of
the grinder – detail
[3]
.
Turn the grinder counter-clockwise to the suit-
able working position – cf. Fig.
[4]
, set the cover
to the maximum cut-through and arrest in this
position.
Tighten sleeve with screw – Fig.
[4 a]
. When
tightening, be careful about the correct right-
angle setting of the grinder’s bearing cover in
the exhaust cover’s sleeve.
Removal
The cutting disc must be dismounted before
the disassembly of the exhaust cover.
Set the cover to a cut depth of 10 mm and put
it down with the grinder at the bottom.
Loosen screw of sleeve.
Set the cover to the top position.
Turn the guiding tab
[5-1]
into the groove on
the grinder’s clamping neck. The turning can
be checked – the corresponding mark is on the
side of the disc – Fig.
[5]
.
Remove the cover from the grinder’s clamping
neck.
7.3 Dust

WARNING
Dust hazard
Always work with a dust extractor.
To ensure suction, put the hose of a Festool
vacuum cleaner class L, M or H into the suction

Diamond cutting disc
8.1 Clamping
WARNING
Do not use quick-change nuts for clamping the
disc!
WARNING
Only use diamond cutting discs recommended
by the manufacturer and the prescribed fl ang-
es included with the cover and the grinder.
-
For reasons of safety, always use original Fes-
tool grinding discs!
-
Sintered cutting discs must not be used!
-
If the permissible revolution speed is given on
the disc, it must not be lower than the highest
no-load speed of the grinder.
-
Discs with a permissible peripheral speed of 80
m/s and higher may be used.
-
Test new cutting discs by letting them run for
about one minute with no load.
-
Unbalanced or vibrating discs should not be
used and should be discarded.
-
Protect grinding discs from shock, impact and
lubricants.
-
If the grinding and cutting wheels are worn
down to the mark on the wheel guard (see the
arrow sign), they should be replaced with new
ones. This maintains the optimum grinding and
