Design features of the power tool
Speed selector thumbwheel
[CT13572-100V, CT13572-115V,
CT13573-115V, CT13573-125V]
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�
Recommendations on the power tool op-
eration
Cutting (see fig. 5.1)
• 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. 5.1. 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�
The manufacturer reserves the possibility to introduce changes.
Grinding (see fig. 5.2)
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�
• 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. 5.2) 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�
Power tool maintenance / preventive
measures
Before carrying out any works on the power tool it
must be disconnected from the mains�
Cleaning of the power tool
An indispensable condition for a safe long-term exploi-
tation 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 flush

the power tool with compressed air thought the ventila-
tion slots 4�
