Design features of the power tool
Brushless motor
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);
•
increased operating time on a single charge;
•
compact design and light weight�
Dust-proof motor
The special design of the motor prevents the accumu-
lation of dust and increases motor's service life�
Temperature protection
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�
Overdischarge protection
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)
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
Kickback protection
shuts down the motor if cutting
disc gets into a sudden stuck situation� In this situation,
turn the power tool off and carefully remove the cutting
disc from the cut� Then turn the power tool on to restart�
Overheating protection
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�
Overload protection
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
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�
Soft start
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�
Break rundown
Break rundown stops the spindle of the power tool
within 2 seconds after the power tool is turned off�
Recommendations on the power tool
operation
Cutting (see fig. 11)
•
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�
•
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�
•
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)
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�
