Crown CT13551-110RSV Originalbetriebsanleitung Seite 20

• Rotate the brush 26 several times - it should
rotate freely, without hitting any parts of the power
tool�
Initial operating of the power tool
Always use the correct supply voltage: the power
supply voltage must match the information quoted on
the power tool identification plate.
Switching the power tool on / off
Switching on:
Press the back part of on / off switch 2 and while holding
it in this position, move on / off switch 2 forward� Press
the front part of on / off switch 2 to fix it in pressed
position�
Switching off:
Push the back part of on / off switch 2�
Dust suction during the power tool
operation
Dust collection decreases dust concentra-
tion in the air and prevents build up of dust
at the work station�
While operating the power tool, always use
a vacuum cleaner suitable for collecting process-
generated dust� A special adapter is used to join the
vacuum cleaner to adaptor 18�
Design features of the power tool
Restart protection
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
Soft start (limiting system of starting current) enables
smooth start of power tools - the spindle is being run
up gradually with no jerks and kickbacks; no jump-like
load is imposed on the motor upon switching�
Rotation stabilizer
Rotation stabilizer (on-load stabilization of rotation)
maintains set rotation rate irrespective of press force
on the surface being treatment - the uniform rotation
rate of the spindle ensures the best quality of treat-
ment�
Speed selector thumbwheel
Using speed selector thumbwheel 17, you may se-
lect the required spindle speed (also during opera-
tion)�
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
Brush selection
Choose the type of a brush (wire, nylon, fibre, abrasive
and other brushes) which is the most suitable for the
work to be carried out�
The intended use of the brush is stated on a package,
you can also consult a seller�
General recommendations
• Switch on the power tool and allow the engine to
reach full speed, and only after that slowly move the
brush 26 to the workpiece being processed�
• Do not apply excessive pressure on the power
tool, it will not provide better results but will cause
the engine to overload and the brush 26 to wear off
faster�
• Move the power tool at constant speed, with
moderate feed, without skewing, oscillatory and jerking
movements�
• It is recommended to perform a trial run on a spare
workpiece to find the best speed for the material being
processed�
• Adjust the position of the front roller 12 as the
brush 26 wears off, as described above�
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
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
flush the power tool with compressed air thought the
ventilation slots 1�
When processing resinous woods, sawdust and grain
can stick to power tool components� During these
works it is necessary to:
• Check cleanliness of the internal surface of the
protective casing 7�
• Keep rollers 12 and 15 clean - their surface must
be clean and they must rotate freely�
• Check the orifice in the dust removal pipe 16 for
obstructions�
• Check ventilation slots 1 (especially on the lower
side of the power tool) for obstructions�
If the above stated components are found to be
clogged, clean them�
