Switching the power
tool on / off
[EX03-125 D, EX03-150 D]
Switching on:
Move forward on / off switch 4.
Switching off:
Move backward on / off switch 4.
[EX03-125 DV]
Short-term switching on / off
To switch on, press and hold on / off switch 4, to switch
off - release it.
Long-term switching on / off
Switching on:
Push on / off switch 4 and lock it in the position with
lock-on button 10.
Switching off:
Push and release on / off switch 10.
Dust suction during
the power tool operation
Dust collection decreases dust concentration
in the air and prevents build up of dust at the
work station.
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 precau-
tions.
Design features
of the power tool
Oscillation rate regulator
[EX03-125 DV]
The oscillation rate regulator 9 is purported to set the
desired oscillation rate of sanding plate 6.
• Push on / off switch 4 and lock it in the position with
lock-on button 10.
• 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 operation
Sanding sheet selection
Prior to commencement of work, select the sanding
sheet 7 type that is most suitable for the processed
material or surface. The type of sanding sheet 7 is
specied on the package. One may also ask the
vendor for more information.
Various works require the use of sanding sheet 7 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
unnecessary element (made of the same
material or with the same coating as the
machined component) to ensure that the
coarseness and type of sanding sheet 7, as well
as the oscillation frequency of the sanding plate 6
have been selected properly.
• Ensure that the element to be sanded is rmly
secured.
• Turn on the power tool earlier, before sanding
plate 6 touches the element to be sanded and allow
the engine of the power tool to reach maximum
oscillation rate.
• Apply sanding plate 6 to the surface of the machined
element and move the power tool in circular or
reciprocating motion.
• Perform sanding with the whole surface of sanding
plate 6.
• 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
sanding sheet 7 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 7.
• Use sanding sheets 7 of varying coarseness
commence the work with a coarse sheet and gradually
proceed to ner sheets. It will make the work faster and
will result in smoother surface.
• Do not reuse sanding sheets 7 that were previously
used for sanding metal for any other materials.
Polishing
[EX03-125 DV]
During polishing, it is recommended
to set lower oscillation frequency of
sanding plate 6 - this will prevent the
overheating of machined surface. Prior
to commencement of work, perform test polishing
to ensure whether the polishing agent and
oscillation frequency of sanding plate 6 have been
selected properly.
• Apply the polishing agent to the machined surface.
• Attach polishing sponge 11 to the sanding plate 6 in
the manner described above.
• Turn on the power tool and spread the polishing
agent on the machined surface. Subsequently, perform
