Dust extraction

CAUTION
Breathing in dust can damage the respiratory
passage!
 Always connect the machine to a dust extrac-
tor.
 When performing work that generates dust,
always wear a dust mask.
A Festool dust extractor with an extractor hose
diameter of 27 mm or 36 mm (recommended due
to the improved suction power) can be connected
to the extractor connector [8-2].
 The special extraction hose and special suction
sleeve [8-1] (available as an accessory) ensure
permanent attachment and protect against
kinking.
 For large surfaces, use the mobile dust extrac-
tor CTL/M 36 E AC P L A N E X because it guar-
antees the necessary continuous suction power.
 Press the green button [8-4] to open the me-
chanical lock [8-3].
 Attach the extraction hose on the dust extractor
to the outlet spigot [8-2].
 Swivel the mechanical lock [8-3] upwards until
it engages.
8 Operation
WARNING
Risk of injury
 Do not hold the machine by the head.
 Hold the machine with both hands.
 Make sure that all clamping levers are closed
before operating the machine.
 Connect the machine to the mains power sup-
ply.
 Before switching on, hold the sanding head a
slight distance away from the working surface.
 Switch on the machine.
 The on/off switch has a zero voltage actuator,
which prevents the machine from starting auto-
matically after the power supply is interrupted
(e.g. after a power failure). After an interrup-
tion in voltage, press the on/off switch [5-2] to
switch the machine on again.
 Perform the necessary sanding work.
 Do not overload the machine by pressing with
excessive force! The best sanding results are
achieved with moderate press-on pressure. The
sanding performance and quality are mainly de-
18
pendent on the selection of the correct abrasive.
 Switch the machine off once the sanding task
is complete.
Visual warning signals on the sanding head
The following visual signals appear on the LED
[10-2] on the motor housing and the machine
decreases in speed if necessary.
LED fl ashing slowly
The machine is overheating due to heavy dirt de-
posits around the air vent slits and the dust fi lter
[10-1].
 Clean the air vent slits.
 Remove the dust fi lter [10-1].
 Remove the dirt deposits.
 Insert the dust fi lter [10-1] until it audibly en-
gages.
 The LED stops fl ashing once the machine is
cleaned and cools down. You can then continue
with your work.
If the LED is still fl ashing after the fi lter sieve and
air vent slits have been cleaned:
 Apply less pressure on the surface.
• Reduce the suction output with the handwheel
[5-3].
LED fl ashing quickly
If a malfunction occurs and the speed signal is
transferred incorrectly from the handle to the mo-
tor, the motor increases to maximum speed when
switched on and the LED [10-2] fl ashes quickly
until the machine is switched off.
 The machine has an internal malfunction. Have
the machine inspected by an authorised service
workshop.
9 Service and maintenance
WARNING
Risk of accident, electric shock
 Always pull the plug out of the socket before
performing any type of work on the machine.
 All maintenance and repair work which re-
quires the motor housing to be opened must
only be carried out by an authorised service
workshop.
 Check the plug and the cable regularly and
should either become damaged, have them
replaced by an authorised after-sales service
workshop.
