Switching the power tool on / off
Switching on:
Move locking button 3 with thumb of the right hand
as shown into fig. 9.2 - this will enable you to pull the
power tool body down and unlock on / off switch 2�
Press on / off switch 2�
Switching off:
In order to switch off the power tool, release switch
button 2�
Dust suction during the power tool op-
eration
Dust suction
concentration in the air and prevents its
accumulation at the workplace� While
operating the power tool, always use a
vacuum cleaner suitable for collecting process-
generated dust� A special adapter is used to join the
vacuum cleaner to coupler 6�
Design features of the power tool
Speed selector thumbwheel
Using speed selector thumbwheel 26, you may select
the required spindle speed (also during operation)�
The required speed is dependent on the material and
can be determined with practical trials�
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 speed and leave your power tool
to run idle�
Soft start
Soft start (limiting system of starting current) enables
smooth start of power tools - the disc is being run up
gradually with no jerks and kickbacks; no jump-like
load is imposed on the motor upon switching�
Rotation speed stabilization system
The stabilization system maintains the preset RPM
both at an idle speed and under load� This allows for
the smooth advance of the power tool during opera-
tion�
Overload protection
Overload protection system of the engine automatically
switches off the power tool in case of overheating
which may arise during cutting the hard wood, the use
of blunt circular saw blades, etc�
Recommendations on the power tool
operation
Cutting depth setting (see fig. 9-10)
Before starting the operation, adjust sawing depth de-
pending on the work piece thickness� The best cutting
allows reducing dust
edge quality is achieved when the projected part of
saw blade 12 does not exceed tooth height�
• Loosen fixing screw 18 (see fig. 9.1).
• To set the depth of the cut, move the screw 18 up
or down� The value of the cutting depth you set is
indicated by the indicator 17 on the scale 20� To adjust
the depth of the cut within 2 mm, use the eccentric 19�
• Tighten fixing screw 18�
Cutting angle setting (see fig. 10)
The power tool enables smooth cutting angle
adjustment within 0°- 45° range�
• Loosen two fixing screws 5 (see fig. 10.1).
• Set required cutting angle on scale 15, changing
power tool body inclination angle (see fig. 10.2).
• Tighten two fixing screws 5�
Remember that during inclined cutting
the cutting depth shown on scale 15 does
not correspond with actual values. In this
case measure the depth of the cut with
the help of a measuring tool (distance "a", see
fig. 10.3).
Cutting marks (see fig. 11-12)
• Cutting mark 10 shows saw blade 12 position during
vertical cutting (see fig. 11).
• Cutting mark 9 shows saw blade 12 position during
cutting at 45° angle (see fig. 12).
Make trial sawing to avoid errors.
Sawing (see fig. 13)
The efficiency and the quality of cutting
operations depends on the state and the
form of saw blade 12 teeth, therefore
proper selection of saw blade is extremely
important depending on the material being pro-
cessed and the type of works being performed.
• Make sure that the work piece is safely fixed.
• Switch on the power tool before saw blade 12 touch-
es the work piece� Let saw blade 12 gain maximal ro-
tating speed�
• Smoothly move down body of the power tool and
move the power tool forward without bending or pushing�
• Never press the tool - sawing requires certain time�
Extra pressure will overload the power tool rather than
facilitate the operation�
• Use additional supports when cutting large sheets
(chipboards, etc�) to avoid bending and possible saw
blade 12 blocking (see fig. 13).
Cutting with parallel guide (see fig. 1, 14)
Parallel guide 28 enables cutting along existing direct
work piece edge, and producing equally wide stripes�
• Loosen fixing screw 4 (see fig. 1.1).
• Move parallel guide 28 to set a required work piece
width�
• Tighten fixing screw 4 (see fig. 1.1).
• Perform the operation as described above (see
fig. 14.1).
