material until the blade completely stops.
Never attempt to remove the saw from the work piece or •
pull the saw backward while the blade is in motion or kickback
may occur.
Investigate and take corrective action to eliminate the cause •
of blade binding.
Wet lumber, green lumber or pressure treated lumber •
require special attention during cutting operation, to prevent
kickback.
Avoid cutting nails. Inspect and remove all nails from lumber •
before cutting.
When you restart a saw in a work piece, center the saw blade •
in the kerfs and check the saw teeth are not engaged into the
material. If the saw blade is binding, it may walk up or kickback
from the work piece as the saw is restarted.
Support large panels to minimize the risk of blade pinching •
and kickback. Large panels tend to sag under their own weight.
Supports must be placed under the panel on both sides, near
the line of cut and near the edge of the panel.
Do not use dulled or damaged blade. •
Unsharpened or improperly set blades produce narrow •
kerfs, causing excessive friction, blade binding and kickback.
Blade depth and bevel adjusting locking knobs must be •
tight and secure before cutting. If blade adjustment shifts while
cutting, it may cause binding and kickback.
Using the saw with an excessive cutting depth, increases •
loading on the unit and susceptibility to twisting of the blade in
the kerfs. It also increases the surface area of the blade available
for pinching under conditions of kerfs close down.
Use extra caution when making a • «pocket cut» into existing
walls or other blind areas. The protruding blade may cut objects
that can cause kickback.
Installation and adjustment of circular
saw elements
CAUTION
Before carrying out any works on the power tool it must be
disconnected from the mains.
Replacement of saw blade
Put the tool on the end of the electric motor case. 1.
While holding the outer flange (13) 2.
with
the pin-spanner (19), unscrew the
saw blade fixing bolt (12) with the help of the spanner (18).
Shift the movable safety guard (11) so that it is completely 3.
inserted into the protective case (4); it shall be done in order to
draw out the saw blade (10) freely.
[F1]
Replace the saw blade (10). When mounting the cutting 4.
blade (10) please make sure that the diameter of the seat bore
matches the diameter of the ridge on the inner flange (21).
Return the movable safety guard (11) into the home 5.
position: teeth of the safety blade (10) must be completely
encased into the movable safety guard (11).
Mount the outer flange (13) (the groove on the outer flange 6.
(13) must be set towards the cutting blade) and, while holding it
with the pin-spanner (19), tighten the saw blade fixing bolt (12)
with the help of the spanner (18).

Dust extraction
Dust extraction prevents large accumulations of
dust, high concentrations of dust in the ambient air
and facilitates disposal.
For long periods of working with wood or for commercial use
on materials that produce dust that is detrimental to health,
the machine is to be connected to a suitable external dust
extraction device.
Initial operation
Always use the correct supply voltage: the power supply voltage
must match the information quoted on the tool identification
plate.
Switching On/Off
Switching On
To switch the machine «on», keep the lock-off button (16)
depressed and press the on/off switch (3).
[F3]
Switching Off
To switch the machine «off», release the on/off switch (3). [F3]
Operating instruction
Make sure that the workpiece is clamped securely. Please •
be sure that the workpiece is positioned face down, as the lower
edge will be thus processed more accurately.
The tool has to be switched on before saw blade (10) •
touches the working piece. Do not apply too much force:
cutting operations are not fast. Excessive force applied will not
accelerate the job, and will result in the tool overload.
Hold the power tool with both hands by both handles, as it •
will provide for the required control of the tool.
Cut marks indicate the position of the saw blade (10) while •
carrying out vertical cuts as, well as cuts at 45°. It is advisable
to carry out a trial cut to eliminate errors in the course of the
operation.
[F4]
Setting the cutting depth
The power tool design enables the stepless cutting depth
adjustment. An accurate cut can be achieved, if the saw blade
(10) overhangs the material by about 3 mm.
