4.1 Speed adjustment
You can regulate the speed steplessly between
6,500 and 8,000 rpm using the adjusting wheel
(2.2).
This enables you to optimise the cutting speed
to suit the material.
4.2 Suction unit
Sanding dust is extracted through the
extraction channels in the sanding pad
directly to the material removal point.
To guarantee optimized dust extraction,
we recommend using Festool extractors
with automatic switch-on/switch-off
device for compressed-air machines.
In order to prevent damage to the pneu-
matic motor, dust extraction must not
be carried out on the pneumatic tool
when it is at standstill.
4.3 Sanding pads
The sanding pads are different in
weight, depending on their diameter.
Fitting sanding pads of incorrect size
causes excessive vibration of the ma-
chine.
Only use sanding pads with an undamaged
burr layer.
The sanding pads are available in three degrees
of hardness to suit the type of application:
- Hard: high edge strength, for removing coar-
se material from surfaces and for sanding
edges.
- Soft: universal for coarse and fi ne sanding,
with elastic structure for even and curved
surfaces.
- Super soft: high elasticity, for smooth fi ne
sanding of moulded parts, curves, radii. Do
not use on edges.
Assembly - see Fig. 4. Make sure the position
of the positive-fi t supports of the sanding pads
(4.1) and the machine (4.2) is congruent.
4.4 Abrasive
Self-adhesive abrasives, such as Stickfi x sand-
paper, and sanding cloths can be affi xed to the
Stickfi x sanding pads.
The abrasives are simply pressed onto the san-
ding pads and removed after use.
The abrasives must be affi xed concen-
trically and the holes aligned with those
on the sanding pad.
5 Maintenance and care
The machine should always be discon-
nected from the compressed air supply
before any work is carried out on the
machine.
Any maintenance or repair work requiring the
motor housing to be opened may only be carried
out by an authorised service workshop.
5.1 Vanes
We recommend that the vanes on the motor be
replaced after approx. 500 operating hours.
5.2 Sanding pad brake
The collar (5.1) makes contact with the sanding
pad, thus preventing the sanding pad from vi-
brating uncontrolledly.
This collar wears out over time and must be
replaced should brake fading occur.
The sanding pad must be removed for this.
You can then remove the collar from the snap-
on fastener (5.2) and replace it with a new
one.
5.3 Lubrication
If the machine is not used for longer periods,
e.g. for a weekend, introduce 1 or 2 drops of
lubricating oil into the compressed-air supply
(5.3) on the machine prior to use.
5.4 Replacing the silencer
The silencer on the IAS 2 connecting piece must
be replaced at regular intervals to maintain the
power of the pneumatic tool.
5.5 Cleaning the extraction channels
We recommend that the extraction channels
in the machine (5.4) be cleaned using a small
pipe-cleaner brush or a cloth once a week (es-
pecially when sanding resin fi ller).
6 Accessories, tools
The accessory and tool order number can be
found in your Festool catalogue or on the In-
