Design features

of the power tool

Speed selector thumbwheel
[WS08-115 V, WS08-125 V]

Using revolution adjustment switch 8, 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 operation

Cutting (see fig. 6)

•

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. 6. 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. 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°

relating to the surface processed (see fig. 6) is rec

ommended� 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

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
