7.3

Inserting the splinterguard

The splinterguard prevents the edges of the mate-

rial from splintering during the cut, even at the end

where the saw blade exits the material.



Switch off the machine and slide the splinter-

guard 

[5-1]

 into the guide 

[5-2]

 and up to the

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 

[1-8]

.



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 

[6-3]

  allows  jigsaws  to  be

connected 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 

[6-2]

 en-

gages in the 

[6-1]

 recess.



To remove the extraction adapter, press the

hook 

[6-2]

.



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

The pendulum stroke on pendulum jigsaws can be

adjusted to machine different materials with the

correct rate of advance. Select the required setting

using the pendulum stroke switch 

[1-11]

:

Position 0 = pendulum stroke off

Position 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 (PSBC 420 EB: 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 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.
