Design features of the power tool
Speed selector thumbwheel
[CT13505-115V, CT13505-125V,
CT13506-125V]
Using revolution adjustment switch 6, 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�
Restart protection
[CT13505-115R, CT13505-125R,
CT13506-125R]
Restart protection - prevents the power tool from
automatically starting up after a power cut� After a
power cut, the power tool must be actively turned off
before it can be started again�
Soft start
[CT13505-115R,
CT13506-125R]
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�

Recommendations on the power tool
operation
Cutting (see fig. 5)
• 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,
CT13506-115R,
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
moderate feed, not distorting and not making vibrating
and bursting movements�
• Cutting should be implemented in the direction
shown on fig. 5. 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
serious injuries appears�
Grinding (see fig. 6)
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�
• 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° relat-
ing to the surface processed (see fig. 6) is recommend-
ed� If this angle is less than recommended, it will make
controlling 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
CT13506-115V,
moderate pressure to the power tool� Excessive
pressure 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�
Power tool maintenance / preventive
measures
Before carrying out any works on the power tool it
must be disconnected from the mains�
CT13506-115R,
Cleaning of the power tool
An indispensable condition for a safe long-term
exploitation of the power tool is to keep it clean� During
the long treatment of metal, current-conducting dust
can be accumulated inside the power tool� Regularly
