turn the power tool off and carefully remove the cutting
disc from the cut. Then turn the power tool on to restart.
inappropriate temperature. When the temperature
conditions are normal, the process of charging will
resume.
Overheating protection
•• Fig. 6.5, 9.5 - (the red indicator 21 is blinking, the
battery 11 is inserted in the charger 14) - the charging
process of the battery 11 is terminated because of its
failure. Replace the faulty battery 11, its further use is
prohibited.
Overheating protection system of the engine automati
cally switches off the power tool in case of overheat
ing. In this situation, let the tool cool before turning the
power tool on again. To switch on the power tool, first
turn it off as described above.
In the process of charging the battery 11
and the charger 14 become hot, it is a
normal process.
Overload protection
Switching the power tool on / off
Overload protection system of the engine automati
cally switches off the power tool when it is operated
in a manner that causes it to draw an abnormally high
current. In this situation, turn the power tool off and
stop the application that caused the tool to become
overloaded. To switch on the power tool, first turn it off
as described above.
Restart protection
Switching on:
Press the back part of on / off switch 5 and while
holding it in this position, move on / off switch 5 for
ward. Press the front part of on / off switch 5 to fix it in
pressed position.
Switching off:
Push the back part of on / off switch 5.
Design features of the power tool
Even if the battery 11 is installed on the power tool
when it switched on still, the power tool does not start.
To switch on the power tool, first turn it off as described
above.
Brushless motor
Soft start
Power tool equipped with a brushless motor that pro
vides the following advantages (compared to the pow
er tool having a brush motor):
•• high reliability due to the lack of wearing parts (car
bon brushes, commutator);
Soft start 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 switch
ing.
•• increased operating time on a single charge;
•• compact design and light weight.
Break rundown
Dust-proof motor
Break rundown stops the spindle of the power tool
within 2 seconds after the power tool is turned off.
The special design of the motor prevents the accumu
lation of dust and increases motor's service life.
Temperature protection
Recommendations on the power tool
operation
Cutting (see fig. 11)
The temperature protection system enables to auto
matically deactivate the power tool in case of excess
load or when the temperature of the battery 11 is ex
ceeding 70°C. The system guarantees protection of
the power tool from damage in case of noncompliance
with the operation conditions.
•• Install cutting disc as described below.
•• Start the power tool, wait until the engine gains its
maximum speed and only after that, smoothly bring
cutting disc to the surface processed.
Overdischarge protection
•• Do not apply excessive pressure to the power tool,
as it will not bring better results but it will overload the
engine and wear out cutting disc faster.
•• Move the power tool along the cutting line with mod
erate feed, not distorting and not making vibrating and
bursting movements.
The battery 11 is protected by the safety system
against deep discharge. In case of complete dis
charge, the power tool is automatically switched off.
Attention: do not try to switch on the power tool
when the protection system is activated the bat
tery 11 can be damaged.
Indicators of the state of battery charge (see
fig. 7, 10)
•• Cutting should be implemented in the direction
shown on fig. 11. When cutting in the reverse direction
the danger of uncontrolled throwing of the power tool
out to the side of the operator, which can lead to seri
ous injuries appears.
Grinding (see fig. 12)
With the push of the button 9 the indicators 8 show the
state of charge of the battery 11 (see fig. 7, 10).
Kickback protection
Grinding is applied for the rough and quick grinding of
metals, the processing of welding seams, etc. Select
the type of grinding disc depending on the work, which
you are going to implement.
Kickback protection shuts down the motor if cutting
disc gets into a sudden stuck situation. In this situation,
