Dust Extraction - SPARKY Professional TK 40 Instrucciones De Uso

between the riving knife (2) and the blade (1) according
the requirement on Fig. 3. If the requirement can not be
fulfilled, replace the blade with a new one, with diameter
corresponding to the indicated in the Technical Speci-
fications.
ADJUSTING THE CUTTING DEPTH
WARNING: Unplug the power tool!
Loosen the depth adjustment lever (14). Hold the base
plate (5) down with one hand and raise or lower the saw
by the back handle (8). Tighten depth adjust lever (14) at
the desired depth setting. (Fig. 4)
To obtain minimum splintering while operating, ensure
that no more than one tooth protrudes through the tim-
ber.
NOTE: During bevel cutting the depth set on scale (13)
does not coincide with the real depth value. In this case
the depth should be measured from the tip of the tooth
to the edge of the slot in the base plate with a measur-
ing tool.
ADJUSTING THE BEVEL
WARNING: Unplug the power tool!
Vertical cutting
Set maximum cutting depth. Loosen bevel adjustment
lever (25), set it to 0º on bevel scale (23), retighten bevel
adjustment lever (25) and check for 90º angle between
the blade (1) and bottom plane of the base plate (5) with
a square.
Bevel cutting
The base plate (5) can be adjusted to 0°–45°. Loosen the
bevel adjustment lever (25). Align it to the desired angle
on calibrated bevel scale (23). Then tighten bevel adjust-
ment lever (25). (Fig. 5)
Due to the increased area of blade engagement in the
work and decreased stability of the base plate, blade
binding may occur. Keep the saw steady and the press
the base plate firmly on the work piece.
Use a protractor when you have to set a precise angle.
LINE GUIDE
For a straight vertical cut, use the cutting guide notch (19)
in the base plate (5). For 45º bevel cuts, use cutting the
guide notch (18). Make sample cuts in scrap timber to
verify actual line of cut.
SWITCHING ON - SWITCHING OFF
WARNING: When starting the circular saw,
hold it securely with both hands. The torque from the
motor can cause the tool to twist.
Switching on: Press the lock-off button (22), and then
squeeze the ON/OFF switch (9).

EN
Switching off: Release the ON/OFF switch (9).
Your saw should be running at full speed before starting
the cut and turned off only after completing the cut.

DUST EXTRACTION

Use a vacuum cleaner during operation. Connect the
vacuum cleaner to the dust extraction port and switch on
the vacuum cleaner prior to starting a cut.
CUTTING
Always hold the back handle (8) with one hand and the
front handle (11) with the other hand.
WARNING: After switching off the saw, be
aware of the necessary time it takes for the blade to
come to a complete stop during coast down. Do not
allow the saw to brush against your body, since the
blade guard (20) is retractable, it could catch on your
clothing and expose the blade (1).
WARNING: Always make sure either hand
does not interfere with the free movement of the lower
blade guard (20).
When cutting is interrupted, to resume cutting, depress
the lock-off button (22), squeeze the ON/OFF switch (9)
and allow the blade (1) to reach full speed, re-enter the
cut slowly and resume cutting.
When cutting across the grain, the fibres of the wood
have a tendency to tear and lift. Advancing the saw slow-
ly minimizes this effect.
Fig. 6 shows the appropriate position for the user. Posi-
tion your body to either side of the blade, but not in line
with the blade as kickback could cause the saw to jump
backwards.
Cutting Large Sheets
Large sheets and long boards sag or bend, de¬pending
on support. If you attempt to cut without levelling and
properly supporting the piece, the blade will tend to bind,
causing kickback and extra load on the motor.
Use timber underneath the sheet or board to raise it for
support. This will ensure a safe and stable cutting opera-
tion. Support the panel or board close to the cut. Be sure
to set the depth of the cut so that you cut through the
sheet or board only and not the table or work bench. If
the sheet or board to be cut is too large for a table or work
bench, use supporting timbers on the floor and secure.
Rip cuts
The rip fence (15) is used when cutting parallel to the
edge of a shaped part. To attach rip fence (15), insert rip
fence through rip fence slots in base plate (5) to desired
width and secure with the rip fence lock knob (17). (Fig. 7)
The distance from the blade to the base surface of the rip
fence shall be set on its scale at guide notch (19) for verti-
cal cutting and guide notch (18) for 45º cutting.
When rip cutting large sheets, the rip fence may not allow
the desired width of cut. Clamp or nail a straight piece of
25mm thick timber to the sheet as a guide. Use the right
side of the base plate against the board guide.
