8 Double insulation
To ensure maximum safety of the user, our tools are designed and
built to satisfy applicable European standards (EN standards). Tools
with double insulation are marked by the international symbol of
a double square. These tools must not be grounded and a two‑wire
cable is sufficient to supply them with power. Tools are shielded in
accordance with EN 55014.
9 Use
The machine is designed to make straight longitudinal and trans‑
verse cuts and cuts at a 45° angle in wood with the use of a fixed
support. The user bears full responsibility for the consequences of
using the machine for purposes it was not designed for.
10 Mounting a Saw Blade
ATTENTION!
Risk of injury from electric current.
Unplug the machine from the power socket before
making any adjustments!
The cutting power and quality of the cut are highly dependent on
the condition and shape of the teeth. Only use sharp saw blades
suited for the given type of material.
When mounting the blade, make sure the orientation
of the teeth aligns with the sense of rotation of the
spindle (indicated by an arrow on the guard).
Lift up the movable guard [3a] using the lever [3b]. On the spin‑
dle [4], place the driving flange [5a], then place the cleaned saw
blade [7] on the spindle [4]. You can put the movable guard back in
place. Mount a cleaned clamping flange [5b] onto the fitting of the
spindle [4], then screw a cleaned clamping screw [6] on top of it.
Tighten the saw blade onto the spindle by inserting the key [8] on
the clamping screw [6], pressing the spindle arresting button [9]
towards the saw motor and tightening the clamping screw [6] with
the key [8].
The saw blade [7] is removed by reversing the procedure.
11 Suction attachment
ATTENTION!
Risk of injury from electric current.
Unplug the machine from the power socket before
making any adjustments!
To connect the suction hose of the vacuum cleaner for chip and
dust extraction, it is necessary to mount the dust extraction adapt‑
er [16a] on the circular saw guard.
Insert the dust extraction adapter [16a] into the upper edge of the
hole for chip extraction [15] and then secure with the fastening
screw [16b].
12 Setting Depth of Cut
ATTENTION!
Risk of injury from electric current.
Unplug the machine from the power socket before
making any adjustments!
Loosen the depth of cut arresting lever [14b].
Adjust the depth of cut to the desired dimension by raising or low‑
ering the circular saw body. Read the approximate value of the set
depth of cut on the scale [14c] at the depth indicator [14d].
Lift up: lower depth of cut
Lower down: higher depth of cut
Re‑tighten the depth of cut arresting lever [14b].
The exact depth of cut value can be determined by holding the
gauge to the saw blade [7] and reading the distance from the lower
side of the guide plate [11] to the saw blade teeth, or by measuring
the depth of the test cut.
ATTENTION!
Depth of cut is set correctly if the saw blade
does not protrude through the other side of the workpiece by
more than 3 mm.
13 Setting Cutting Angle
ATTENTION!
Risk of injury from electric current.
Unplug the machine from the power socket before
making any adjustments!
Loosen the angle locking screws [12c].
Use the blade angle scale [12a] to approximately set the angle of
choice (the angle scale is graded in 15° increments).
Re‑tighten the angle locking screws [12c]. You can find out the
exact value of the set angle by measuring the angle between the
lower side of the guide plate [11] and the cutting blade [7], or by
measuring the bevel angle on the test cut.
ATTENTION!
The depth of cut when cutting at an angle is
lower than indicated on the depth of cut scale.
14 Precise setting of the cutting
perpendicularity
ATTENTION!
Risk of injury from electric current.
Unplug the machine from the power socket before
making any adjustments!
Perpendicular cut stop [12d] is set at the factory. Over time, as a
result of vibrations, impacts etc., the saw blade may be deflected
(within a tenth of an angular degree) from the perpendicular plane
to the guide plate [11] of the circular saw. You can achieve a precise
perpendicular cut by readjusting the perpendicular stop [12d]. You
can turn the perpendicular cut stop and readjust the perpendicular
cut with a 3 mm Allen key (screwdriver) inserted into the hole on
the lower side of the guide plate. Verification of the perpendicular‑
ity of the cut is best achieved through a test cut of thicker material
using an angle.
15 Parallel Stop (Guide)
ATTENTION!
Risk of injury from electric current.
Unplug the machine from the power socket before
making any adjustments!
Slide the scale guide [13] into the guide slot [13a] on the guide
plate [11] and secure it with the guide fastening screw [13b]. The
guide allows for the making of parallel cuts along a straight edge
and cutting strips of identical sizes.
