• Facilitated by pivot fixing, the support plate 1 au-
tomatically slopes depending on surface slope angle
(see fig. 2).
• To move the support plate 1 forward or backward,
do the following:
• turn the locking lever 5 as shown on figure 3.1;
• set the support plate 1 into required position by
moving it forward or backward (see fig 3.2);
• turn the locking lever 5 as shown on figure 3.3.
Initial operation
of the power tools
Always use the correct supply voltage: the power sup-
ply voltage must match the information quoted on the
power tool identification plate.

off - release it�
Long-term switching on / off
Switching on:
Push on / off switch 8 and lock it in the position with
lock-on button 9�
Switching off:

of the power tool
Stroke rate selection
Using the thumbwheel for stroke rate selection 7 one
may select the needed number of stroke of the saw
blade 10 (also when operating the power tool)�
• Push on / off switch 8 and lock it in the position with
lock-on button 9�
• By moving the thumbwheel for stroke rate
selection 7, select the needed number of stroke of the
saw blade 10�
Following setting up the number of stroke rate of the
saw blade 10 it is recommended to make a test saw
cut using a spare piece of the blank part (made of the
same material as the part to be processed)�
When operating your power tool at a low speed for a
long time, it has to be cooled down for 3 minutes� To
do it, set a maximum stroke rate and leave your power
tool to run idle�
Steeples regulation of a number of saw blade
strokes
Change of the number of strokes from 0
to maximum also depends from the force
applied on the switch 8� A weak press
means a small number of strokes; this
allows turning on the power tool smoothly may be re-
quired for specific kinds of work.
on the power tool operation
Selecting the saw blade
Before starting the operation, please select the appro-
priate type of the saw blade 10 which should corre-
spond to the sawed material, sawing regime and the
quality of the edge of the saw cut� The designation of
the saw blade is printed on the package; you may also
ask the salesperson�
General guidelines for cutting
Before starting, use a sample work-
piece (made of the same material as the
workpiece to be processed) to perform
trial cutting in order to verify that saw
blade 10 has been properly selected and an appro-
priate speed has been set.
• Make sure that the workpiece is tightly fastened and
that all of the metal pieces (nails, screw nails, etc�)
have been removed from it�
• Turn the power tool on before the saw blade 10
comes in contact with the workpiece� Do not use extra
force; the operation requires some time� Extra force
will not speed up the operating process, but it will over-
load the power tool�
• When the teeth of the saw blade 10 are too large
for the workpiece (excessive vibration, splitting and
chipping of the processed surface will serve as a sign
of the teeth being too large), turn off the power tool
immediately and replace the saw blade 10 with the ap-
propriate blade�
• If the saw blade 10 jams during the operation, turn
off the power tool immediately and try to expand the
saw cut, then carefully remove the saw blade 10 from
the saw cut� Caution: do not try to remove the
jammed saw blade 10 by swinging it in the kerf
with the power tool switched on, for it may cause
breakdown of the saw blade 10 and injury.
• After the cutting is finished, first turn the power tool
off and then remove the saw blade 10 from the saw cut�
When cutting certain materials (like met-
als), the saw blade 10 may heat up ex-
cessively, therefore it is recommended
to use cooling or lubricating substances
which are to be applied to the point where the saw
blade 10 comes in contact with the workpiece.
Cutting along the curved path
Curved path sawing is possible when the narrow saw
blades 10 are used�
Plunge sawing (see fig. 4)
Plunge sawing may be used only when
sawing soft materials, such as wood,
plasterboard, etc. This operating tech-
nique
without preliminary drilling - the saw blade 10 cuts
through the blank part on its own. This technique
requires certain skill and may be applied using
short saw blades 10.
• This method allows making a kerf not from the edge
of the workpiece and without preliminary drilling, saw
