9. TYPES OF CUTS
Operating Recommendations:
Saw Blade Selection
T type 15 saw blades can be used with
all jigsaw models.
Before starting to operate, select the appropriate type
of saw blade 15 that corresponds to the sawed material,
cutting regime, and quality of the saw cut edge. The
designation of the saw blade is printed on the package.
General Cutting Guidelines
Before cutting, test with a piece similar
to the one you will cut (made of the same
material), to ensure that the saw blade
15, cutting speed, and pendulum stroke
have been selected correctly.
• Make sure that the piece to be cut is well secured
and that all metal pieces (nails, screws, etc.) have been
removed from it.
• Start the power tool before the saw blade 15 comes into
contact with the piece to be cut. Do not use additional
force; the operation takes time. Additional force will
not speed up the operation but will overload the tool.
• If the teeth of saw blade 15 are too large for the piece
to be cut (excessive vibration, the processed surface
cracks and chips, signs that the teeth are too large),
immediately turn off the power tool and replace saw
blade 15 with the appropriate blade.
• If saw blade 15 gets stuck during operation, immediately
turn off the power tool and try to expand the saw cut,
then carefully change saw blade 15 from the saw cut.
• After finishing the cut, first turn off the power tool
and then change saw blade 15 from the saw cut.
When cutting certain materials (such as
metals), saw blade 15 can overheat, so it
is recommended to use cooling or lubri-
cating substances that should be applied
at the point where saw blade 15 comes
into contact with the piece to be cut.
Plunge Cut (see Fig. 5)
9.1. CUT ANGLE ADJUSTMENT (Fig. 8)
The design of the power tool facilitates making angular
saw cuts by angling the tool's housing. The base plate
11 of the power tool contains a scale 12 that marks the
angles of the tool's housing (the step is 15°). If additional
measuring instruments are used, one can position the
tool's housing at any angle (within the limits specified
in the technical data table).
• Loosen the locking lever 13 (Fig. 9).
• Change the base plate 11 forward and select the
necessary angle using the index readings 12.
• Adjust the locking lever 13.
9.2. VERTICAL CUTS
The base is placed in its maximum backward position,
with the saw blade centered.
To start work on wood in interior cuts (Fig. 5) you can
support the assembly by the front part of the base plate
and slowly press until the saw blade has gone through
the material to be worked on.
In case of lack of practice or when working on other
materials, a preliminary hole is necessary.
For this operation, the pendulum mechanism, regulated
by the control 13 (Fig. 9), must be in position 0.
9.3. CUTTING WITH THE CIRCLE / PARALLEL
CUTTING GUIDE BAR
Circle Cut (Fig. 6)
The parallel/circle cutting guide bar 18 allows circular
cuts at a fixed radius.
• Mark the circle to be cut and make a hole in the
center (the diameter of the hole should be equal to the
diameter of the positioning pin 17).
• If you do not wish to start cutting from the edge of
the workpiece, make a hole at the starting point as in
(Fig. 6) (the diameter of the hole should exceed the
width of saw blade 15).
• Loosen the wing screws 8 (Fig. 1).
• Flip the parallel/circle cutting guide bar 18 and place
as in (Fig. 6).
•Move the power tool to the starting point. If you
do not intend to start cutting from the edge of the
workpiece, insert saw blade 15 into the hole made at
the starting point.
• Set the operational radius for the circular cutting
movement guide bar for parallel/circle cutting 18 until
the hole made for the positioning pin 17 coincides with
the central hole of the circle.
• Insert the positioning pin 17 into the parallel/circle
cutting guide bar 18 and simultaneously into the central
hole of the circle.
• Tighten the wing screws 8 (Fig. 1) to fix the guide bar
18 for circular/parallel sawing.
• Start cutting along the marked circle with one hand
while holding the positioning pin 17 with the other hand.
Use narrow 15 saw blades (Fig. 1) for
circular or curvilinear cuts to improve
quality and facilitate the operation.
