Choice and installation of the
grinding disks
The appliance can be fitted with three grinding
disks (5.1) of different hardness depending on
the surface to be treated.
- Hard: coarse grinding on surfaces, grinding
at edges.
- Soft: universal for coarse and fine grinding,
for flat and curved surfaces.
- Super-soft: fine grinding on formed parts,
curves, radii. Do not use on edges!
The grinding disks and the tool-holding fixture
on the appliance are equipped with a positive
holder (6.1).
Make sure the grinding disk is
correctly positioned before screwing it tight.
Working with the machine
Never overload the tool by using
too much pressure! The best sanding results
are achieved when applying moderate pressure.
The ETS 150/3 EQ gives the best surface quality
and low abrasion. The ETS 150/5 EQ provides
high abrasion with good surface quality. The
sanding performance and quality depend mainly
on the choice of the right sanding material.
Festool offers the appropriate sanding material
for all applications (see Festool catalogue or
on the Internet under "www.festool.com").

rotary control (2.3) for electronic machines:

Maintenance and care
Any maintenance or repair work
requiring the motor housing to be opened may
only be carried out by an authorised service
workshop. Maintenance or repair work carried
out by an unauthorised person can lead to the
wrong connection of the power leads or other
components, which in turn can lead to accidents
with serious consequences.
Always remove the plug from the
mains supply socket before carrying out any
work on the machine!
Always keep the machine and the ventilation
slots clean.
Sanding base brakes
The sanding base is braked by a collar (6.2) in
order to prevent any uncontrolled excessive
speed of the sanding base. Because the collar
wears down in the course of time, it has to be
replaced by a new one (order no. 453 388) as
soon as there is any reduction in the braking
effect.
