Overdischarge protection
The battery 10 is protected by the safety system
against deep discharge� In case of complete dis-
charge, the power tool is automatically switched off�
When this protection system is activated - one indica-
tor 12 fast blinking (see fig. 8.2). Attention: do not
try to switch on the power tool when the protec-
tion system is activated the battery 10 can be
damaged.
Working modes (see fig. 9)
"MODE 1" (grinding / cutting) - you can
find the values of the revolutions per min-
ute range in the technical specifications
table� This working mode is suitable for
cutting or grinding� Press and release mode switch 11,
when this working mode is selected, indicator 14 will
light up (see fig. 9.1).
"MODE 2" (polishing / waxing) - you
can find the values of the revolutions per
minute range in the technical specifica-
tions table� This working mode is suitable
for polishing or waxing� Press and release button 11,
when this working mode is selected, indicator 13 will
light up (see fig. 9.2).
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 switching�
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. 9.1, 10.1)
• Install cutting disc as described below�
• Set working mode for grinding / cutting ("MODE 1"),
as described above (see fig. 9.1).
• 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. 10.1. When cutting in the reverse direc-
tion the danger of uncontrolled throwing of the power
tool out to the side of the operator, which can lead to
serious injuries appears�
Grinding (see fig. 9.1, 10.2)
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�
• Install grinding disc as described above�
• Set working mode for grinding / cutting ("MODE 1"),
as described above (see fig. 9.1).
• Start the power tool, wait until the engine gains its
maximum speed and only after that smoothly bring
grinding disc to the surface processed�
• Holding the power tool at an angle of 10° to 15° relating
to the surface processed (see fig. 10.2) is recommended.
If this angle is less than recommended, it will make con-
trolling the power tool more difficult. If this angle is more
than recommended, the processing quality will decrease
and grooves will be left on the billet surface�
• Make alternate-reciprocal movements applying
moderate pressure to the power tool� Excessive pres-
sure will not bring better results but it will overload the
engine and create the danger of destruction of grinding
disc, which can cause severe injuries�
Polishing (see fig. 2, 9.2)
• Dismount protective casing 1 as described above
(see fig. 2).
• Install accessories for polishing�
• Set working mode for polishing / waxing ("MODE 2"),
as described above (see fig. 9.2).
• It is strongly recommended to use liquid polishing
compounds� Never use abrasive or grinding com-
pounds� Abrasive components may damage coated
surfaces�
• Run the power tool idle for one minute before the
operation�
• Regularly apply the polishing compound on the sur-
face during polishing�
• When applying the polishing compound on the pol-
ishing accessory leave approximately one forth of the
working surface uncovered by the compound�
• If the part being processed is heated up, stop opera-
tion and let it cool down to avoid deformation�
Power tool maintenance /
preventive measures
Before carrying out any works on the power tool
remove the battery 10.
Cleaning filter
Regularly inspect filter 8 (its contamination depends
on the state of the environment). Clean the filter 8
with soft brush as it gets dirty� Attention: do not use
power tools without a filter 8.
Battery maintenance instruction
• Charge timely before the battery 10 is completely
exhausted� Stop operation in low power and charge it
immediately�
• Do not overcharge when the battery 10 is full, other-
wise it will shorten the life time�
• Charge battery 10 in the room temperature of 10°C
to 40°C (50°F to 104°F)�
• Charge battery 10 every 6 months without operation
for a long time�
• Replace worn out batteries in time� Decline of
production or a significantly shorter runtime of the
power tool after charging indicates aging of the
battery 10 and the need for replacement� It should
be taken into account that the battery 10 may dis-
