Operation
Chip-flyoff guard
The splinter guard 10 can prevent fraying of the
surface while sawing wood.
This application can only be used when cutting at
a right angle (90°).
Press the splinter guard 10 from below into
the base plate 4 shown in the figure).
Dust extractor
The jigsaw is equipped to be connected to a com-
merically available vacuum cleaner.
In order to keep the cut free of shavings, the
flexible suction tube is inserted from the back
into the housing opening 9.
The dust hood 3 is to be pushed downwards
until it locks into place.
In the case of mitre cuts, the dust hood is to
be pushed upwards.
Changing the tool
Disconnect the plug from the power
source before making any adjust-
ments, changing accessories, or
storing power tools.
Such preventive safety measures
prevent accidental start of the power
tool.
Wear safety gloves for tool changing.
The tool insert can become very hot
after working for long periods and/or
the cutting edges of the tool insert
are sharp.
The advantage of the clamping system is that saw
blades can be changed without tools.
The protection roller, which prevents the saw
blade from moving and serves to unburden the
mechanical parts (tappet), automatically produces a
clamping angle of 90° as a positive stop. Naturally,
this only applies when original saw blades are
used.
Inserting the Saw Blade „B"
First push the dust hood 3 up.
Rotate clamping lever 8 as far as it will go and
hold in place.
Insert saw blade 7 as far as it will go.
Release clamping lever 8.

-WARNING-
Press jigsaw against saw blade tip on wooden
board, until clamping lever 8 springs back to its
starting position.
It is only by doing this that the secure clamping of
the saw blade 7 can be ensured and the hood 3
can be closed.
-NOTE-
Check the tight seating of the saw blade.
A loose saw blade can fall out and lead to injuries.
Unclamping saw blade
Rotate clamping lever 8 as far as it will go and
hold in place.
Remove saw blade 7.
-NOTE-
Do not press back turned clamping levers as this
makes it very difficult to remove the saw blade.
Operating tips
Operation of pendulum jigsaw
When sawing, make sure that the base plate is sit-
ting securely on the workpiece. The jigsaw can
now be easily operated by hand. To achieve clean
cuts and optimal cutting performance, make sure
the correct pendulum stroke for the material has
been selected on the feed, which should also be
adjusted for the material (e.g. pendulum stroke
setting 0 and slow feed when sawing metals).
The built-in blower keeps the cut continuously free
of chips for perfect visibility.
Recommended stroke numbers
The optimal speed setting is to be determined in
tests at the beginning of the sawing job, as several
factors such as material, thickness of material,
condition of the saw blade, may influence the
results of the job.
Low stroke number when sawing glass, ceramics,
metal.
Medium-range stroke number when sawing
plastic, pressed material and plywood.
High stroke number when working hardwood,
soft wood and chipboard.
