wing nut 9 (see fig. 1.1).
• During dismantling of supporting plate 4 repeat the
operations described above in reverse order�
• Adjust timely the distance between supporting
plate 4 and grinding disc 3, for this purpose loos-
en wing nut 9 and move supporting plate 4 in the
direction of grinding disc 3� The distance between
supporting plate 4 and grinding disc 3 should not
exceed 2 mm�
If the wear of grinding disc 3 is so heavy
that it does not allow adjusting the dis-
tances between grinding disc 3 and sup-
porting plate 4 it is necessary to replace
the grinding disc.

Installation / change of grinding disc (see
fig. 3-5)
After installation of the grinding disc and
before starting work make a trial start-up
switch on the power tool and let it idle
run for at least 5 minutes. It is prohibited
to use grinding discs that cause beats and in-
creased vibration of the power tool.
• Remove cover 2 and protective housing 1 as shown
on fig. 3.
• Holding grinding disc 3 with one hand unscrew
nut 21 (see fig. 4). Attention: nut 21 used to fix the
left grinding disc has left-hand threading.
• Dismantle from spindle 18: flange 19, gasket 20,
grinding disc 3, gasket 20, flange 19�
• Clean all the parts by the soft brush and mount on
spindle 18: flange 19, gasket 20, grinding disc 3, gas-
ket 20, and flange 19� Attention: mount flanges 19
exactly as shown on fig. 5, do not turn them.
• Holding grinding disc 3 with one hand, screw nut 21�
• Install protective housing 1 and cover 2�
• Fix the position of cover 2 with the help of fasten-

LED lamp
[CT13545L, CT13546L, CT13547L]
When the on / off switch 12 (switch "ON" 11 for
CT13547L) is pushed, the LED lamp 22 is automati-
cally switched on that allows to carry out works in low
light conditions�
Flexible holder allows you to change the position of the

Recommendations on the power tool op-
eration
Select the type and grain structure of
grinding disc 3 depending on the ma-
chined material and the roughness of
the surface that you are expecting to
achieve.
• Put the power tool on the work table, it is desirable to
fix it with the use of bolts (see fig. 6) or clamps.
• Start the power tool, wait until grinding disc 3 has
reached its maximum rotation speed and smoothly
move the workpiece placed on supporting plate 4 to
grinding disc 3�
• Do not apply excessive pressure to the workpiece,
as it will not bring better results but it will overload the
engine and wear, the workpiece will be heated and
grinding disc 3 will be worn out more quickly�
• Move the workpiece to the left / the right a little bit� It
will ensure even wear of grinding disc 3�
• It is recommended to place the workpiece in the wa-
ter from time to time in order to avoid its overheating
during treatment�
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�
