Use of vacuum cleaner
During prolonged wood machining or when processing
materials that produce dusts hazardous to health, the
power tool should be connected to a proper vacuum
cleaner�
Given power tools may cooperate with the vacuum
cleaner only when used with a relevant connector�
One should monitor dust level in the bag and empty the
bag at relevant time, taking the aforesaid precautions�
Design features of the power tool
Oscillation rate regulator
[CT13560V, CT13395]
The oscillation rate regulator 4 is purported to set the
desired oscillation rate of sanding plate 8�
[CT13395]
• Push on / off switch 5 and lock it in the position with
lock-on button 6�
• Set the desired oscillation rate�
The required oscillation rate depends on the type of
processed material, work conditions and must be set
on the basis of practical trials for best results�
During prolonged work at low oscillation rate, one
should allow the power tool to cool down for 3 minutes�
For this purpose, set the maximum oscillation rate and
allow the power tool to work without load�
Recommendations on the power tool op-
eration
Sanding sheet selection
Prior to commencement of work, select the sanding
sheet 9 type that is most suitable for the processed
material or surface� The type of sanding sheet 9 is
specified on the package. One may also ask the ven-
dor for more information�
Various works require the use of sanding sheet 9 of
different coarseness, allowing a surface of required
smoothness to be obtained� The best method to select
sanding sheet, is to practically test for best results�
Sanding
Prior to commencement of work one
should perform test sanding on an un-
necessary element (made of the same
material or with the same coating as the
machined component) to ensure that the coarse-
ness and type of sanding sheet 9, as well as the
oscillation frequency of the sanding plate 8 have
been selected properly.
• Ensure that the element to be sanded is firmly se-
cured�
• Turn on the power tool earlier, before sanding plate 8
touches the element to be sanded and allow the engine
of the power tool to reach maximum oscillation rate�
• Apply sanding plate 8 to the surface of the machined
element and move the power tool in circular or recip-
rocating motion�
• Perform sanding with the whole surface of sanding
plate 8�
• Do not press the power tool excessively, since this
will not provide better results, but will only overload the
engine of the power tool and will result in higher sand-
ing sheet 9 consumption�
• Do not stop the power tool in a single spot this will
result in a depression in the stoppage place�
• At relevant time, replace the used or dust-blocked
sanding sheets 9�
• Use sanding sheets 9 of varying coarseness com-
mence the work with a coarse sheet and gradually pro-
ceed to finer sheets. It will make the work faster and
will result in smoother surface�
• Do not reuse sanding sheets 9 that were previously
used for sanding metal for any other materials�
Polishing
[CT13560V, CT13395]
During polishing, it is recommended
to set lower oscillation frequency of
sanding plate 8 - this will prevent the
overheating of machined surface. Prior
to commencement of work, perform test polishing
to ensure whether the polishing agent and oscil-
lation frequency of sanding plate 8 have been se-
lected properly.
• Apply the polishing agent to the machined surface�
• Attach polishing sponge 11 to the sanding plate 8 in
the manner described above�
• Turn on the power tool and spread the polishing
agent on the machined surface� Subsequently, per-
form the polishing with circular or cross movements
with little pressure�
• Turn off the power tool, remove polishing sponge 11
and attach polishing bonnet 12 to sanding plate 8�
• Using a soft cloth, remove excess polishing agent
from the machined surface and perform final polishing
with polishing bonnet 12, with circular or cross move-
ments with little pressure�
• After the work is completed, rinse polishing
sponge 11 and polishing bonnet 12 in warm water with
a cleaning agent� Do not use solvents.
• Squeeze (do not wring) polishing sponge 11 and
polishing bonnet 12� Allow them to dry, stretching them
on flat surface, adhesive surface on the bottom. Atten-
tion: do not store the polishing accessories unless
they have dried out completely.
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� Regularly
flush the power tool with compressed air thought the
ventilation slots 3�
