saw blade,
 Switch on the jigsaw,
 On a level surface, slide in the splinterguard
(not using your hand!)while the machine is op-
erating until it is flush with the front edge of the
saw base (speed setting 5). This beds in the
splinterguard.
 When it is worn, push the splinterguard approx.
3 mm further to the rear and continue using it.
 To guarantee reliable operation of the splinter-
guard, it must seal tightly on both sides of the
saw blade. A new splinterguard should there-
fore be fitted after every saw blade change to
guarantee splinter-free cuts.
7.4 Changing saw table
 Open the change lever [1-9].
 Removing the saw table downwards.
 Assembly is performed in reverse sequence to
removal. Ensure that the saw table is firmly
seated in the guide.
Instead of the saw table, the angle table WT-PS 400
or adaptation table ADT-PS 400 can be installed at
the support.
Never saw without the saw table, or one of
the other tables offered in the Festool acces-
sories program.
7.5 Dust extraction
The extraction adapter [5-3] allows jigsaws to be con-
nected to a dust extractor (hose diameter 27 mm).
 Insert the extraction adapter into the rear open-
ing of the saw table so that the hook [5-2] en-
gages in the [5-1] recess.
 To remove the extraction adapter, press the
hook [5-2].
 Due to the low power consumption of the ma-
chine (low energy consumption), dust extractors
with an automatic switch-on function will some-
times only start up when the actual cut is made.
 Set the dust extractor to continuous operation
for special applications (e.g. low stroke rate,
soft wood).
7.6 Adjusting the pendulum stroke
In order to process different materials with an opti-
mum feed movement the pendulum jigsaws have
an adjustable pendulum stroke. Select the desired
setting with the pendulum stroke switch [1-12]:
setting 0 = pendulum stroke off
setting 3 = maximum pendulum stroke
7.7 Stroke speed control
The number of strokes can be adjusted steplessly
with the adjusting wheel [1-5] between 1500 and
3800 rpm (PSB 420 EBQ: 1000 - 3800 rpm). This en-
ables you to optimise the cutting speed to suit the
respective material.
In position A, the automatic load detection is acti-
vated: The stroke speed is reduced in idling and is
controlled to the highest value when the blade en-
ters the workpiece.
8 Working with the machine
When working on small or thin workpieces, always
use a stable base, or the CMS module (accessory).
When working, hold the electric power tool by the
handle and guide it along the desired cutting line.
For precise cuts and smooth running, use two
hands to guide the electric power tool.
WARNING
Dust hazard
 Dust can be hazardous to health. Always work
with a dust extractor.
 Always read applicable national regulations be-
fore extracting hazardous dust.
