Design features of the power tool
Speed selector thumbwheel
Using speed selector thumbwheel 13, 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�
Soft start
[CT11002, CT11001]
Soft start (starting current limitation system) allows for
the soft start of the power tool - the router bit spins
up gradually without jerks and recoils, and when the
power tool is turned on, this does not impose an abrupt
load on the power network�
Rotation speed stabilization system
The stabilization system maintains the preset RPM
both at an idle speed and under load� This allows for
the smooth advance of the power tool during operation�
Recommendations on the power tool op-
eration
Setting milling depth (see fig. 12-16)
The adjustment of the milling depth may
only be carried out when the power tool
is switched off.
[CT11012]
• Install the power tool on the even horizontal surface�
• Turn stepped stop 20 so that its lowest step is under
depth gauge 14 (see fig. 12.1).
• Release clamping screw 17 (see fig. 12.2).
• Move lever 8 up (see fig. 12.3) - this will allow the
power tool body to move�
• Lower the power tool body so that the router bit
end touches the workpiece surface, and move lever 8
down to fix the position of the power tool body (see
fig. 12.4).
• Move depth gauge 14 so that its end touches the
surface of stepped stop 20 (see fig. 13.1). Thus, you
have fixed the "zero position".
• In order to set the milling depth, move depth
gauge 14 up with reference to indicator 15 readings on
scale 34, after which tighten locking screw 17 to fix the
preset milling depth (see fig. 13.2). Now when depth
gauge 14 end touches the lowest step of stepped
stop 20, the preset milling depth will be reached (see
fig. 13.3). When necessary, you can reach the desired
milling depth at several passes� For this purpose,
rotate stepped stop 20 so that depth gauge 14 end
rests alternately upon higher steps of stepped stop 20�
• After the works are finished, move lever 8 up and
smoothly raise the power tool body to the uppermost
position, while holding the power tool with both
handles 3�
[CT11002, CT11001]
• Install the power tool on the even horizontal surface�
• Turn stepped stop 20 so that its lowest step is under
depth gauge 14 (see fig. 14.1).
• Release clamping screw 17 (see fig. 14.2).
• Move lever 8 down and hold it in this position (see
fig. 14.3) - this will allow the power tool body to move.
• Lower the power tool body so that the router bit end
touches the workpiece surface, and release lever 8
(lever 8 automatically returns to its original position) to
fix the position of the power tool body (see fig. 15.1).
• Move depth gauge 14 (rotate the flywheel 16 for
this purpose) so that adjusting screw 19 touches the
surface of the stepped stop 20 lower step� If necessary,
release locknut 18 and untwist adjusting screw 19 (so
that its end touches stepped stop 20), and then tighten
locknut 18 (see fig. 15.2 and 15.4). Thus, you have
fixed the "zero position".
• Move indicator 15 to the "0" mark of depth gauge 14
scale (see fig. 15.3).
• In order to set the milling depth, move depth
gauge 14 up with reference to the scale marking, after
which tighten locking screw 17 to fix the preset milling
depth (see fig. 16.1-16.3). Now when adjusting screw
end 19 touches the lowest step of stepped stop 20,
the preset milling depth will be reached (see fig. 16.4).
When necessary, you can reach the desired milling
depth at several passes� Rotate stepped stop 20 for
this purpose so that adjusting screw 19 end rests alter-
nately upon the higher steps of stepped stop 20�
• A more accurate adjustment of the milling depth can
be made using controller 7�
• After the works are finished, move lever 8 down,
hold it in this position, and smoothly raise the power
tool body to the uppermost position, while holding the
power tool with both handles 3� Release lever 8�
Milling direction (see fig. 17)
Milling should always be performed against the
router bit rotation direction (see fig. 17). Oth-
erwise, the power tool will be subject to jerks,
which may result in the loss of control over it�
General operational recommendations (see fig. 18-19)
• Mark out and fix the machinable workpiece.
• Set the desired milling depth as described above�
• Turn on the power tool�
• CT11012 - move lever 8 as shown in figure 18 (this
will allow the power tool body to move)� Lower the
power tool body slowly and smoothly until the preset
milling depth is reached� Fix the body in this position
by moving lever 8 as shown in figure 18.
• CT11002, CT11001 - move lever 8 down and hold it
in this position as shown in figure 19 (this will allow the
power tool body to move)� Lower the power tool body
slowly and smoothly until the preset milling depth is
reached� Release lever 8 to fix the body in this position
as shown in figure 19.
• Perform the milling operation with a uniform ad-
vance, observing the recommendations concern-
ing the milling direction� Hold the power tool with
both hands by both handles 3� Do not apply extra
effort - performing the operation will take some time�
Extra effort will not expedite the working process, but
will overload the power tool�
• After the milling process is finished, raise the power
tool body to the uppermost position as described above�
• Turn the power tool off�
