4.1 Speed adjustment
You can regulate the speed steplessly between
4,000 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
pneumatic 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
machine.
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
coarse material from surfaces and for sanding
edges.
- Soft: universal for coarse and fine sanding,
with elastic structure for even and curved
surfaces.
- Super soft: high elasticity, for smooth fine
sanding of moulded parts, curves, radii. Do
not use on edges.
Assembly - see Fig. 4. Make sure the position
of the positive-fit supports of the sanding pads
(4.1) and the machine (4.2) is congruent.
4.4 Abrasive
Self-adhesive abrasives, such as Stickfix
sandpaper, and sanding cloths can be affixed
to the Stickfix sanding pads.
The abrasives are simply pressed onto the
sanding pads and removed after use.
The abrasives must be affixed
concentrically and the holes aligned
with those on the sanding pad.
5 Maintenance and care
The machine should always be
disconnected 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
vibrating 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
(especially when sanding resin filler).
