Crown CT11020 Original Instructions Manual page 19

• Tighten nut 10 using the open end wrench 13� Note:
never tighten nut 10 without the router bit - this can
damage collet 19�
• After all the operations have been completed, re-
lease spindle lock 9�
Assembling / dismantling of dust extractor con-
necting adaptor (see fig. 2)
• Install adaptor 15 as shown in figure 2.
• Connect the external dust extracting device to adap-
tor 15 (use a suitable adaptor if necessary)�
• Disassembly operations do in reverse sequence�
Parallel guide assembly / adjustment / installation
(see fig. 3-4)
• Assemble parallel guide 17 as shown in figure 3.
• Lock the parallel guide 17 on the base plate 5 as
shown in figure 4.
• Parallel guide 17 has an adjusting screw 23 provid-
ing for the fine adjustment. For this purpose perform
the following:
• weaken the locking screw 25;
• rotate the adjusting screw 23 to move the thrust
plate 24;
• notice that there is a scale at the bottom of the
thrust plate 24, that shows the distance at which the
thrust plate 24 was moved;
• tighten the locking screw 25�
• Disassembly operations do in reverse sequence�
Initial operating of the power tool
Always use the correct supply voltage: the power sup-
ply voltage must match the information quoted on the
power tool identification plate.
Switching the power tool on / off
Short-term switching on / off
To switch on, press and hold on / off switch 7, to switch
off - release it�
Long-term switching on / off
Switching on:
Push on / off switch 7 and lock it in the position with
locking button for on / off switch 6�
Switching off:
Push and release on / off switch 7�
Dust suction during the power tool op-
eration
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-gener-
ated dust� A special adapter is used to join the vacuum
cleaner to adaptor 15�
Recommendations on the power tool op-
eration
Setting milling depth (see fig. 5-8)
The adjustment of the milling depth may
only be carried out when the power tool
is switched off.
• Install the power tool on the even horizontal sur-
face�
• Unscrew the locking screws 2 - this will provide for
the possibility to move the power tool body freely (see
fig. 5.3).
• Unscrew the locknut 3 - this will provide for the pos-
sibility to move the milling depth gauge 1 freely (see
fig. 5.2-5.3).
• Move the milling depth gauge 1 upward (see fig. 6.1).
• Lower the power tool body, so that the end of the
router bit could touch the work piece surface (see
fig. 6.2). Tighten the locking screws 2 while keeping
the power tool body in this position (see fig. 6.3).
• Move the milling depth gauge 1 downward, till its
end touches the stop lug 4 (see fig. 7.1). As a result,
you have locked the "zero position"�
• To set the milling depth, move the milling depth
gauge 1 upward (see fig. 7.2) orienting by the scale 11
(it is recommended to use an additional measurement
tool for more accurate installation)�
• Tighten the locknut 3 to lock the set milling depth
(see fig. 8.1).
• Unscrew the locking screws 2 - this will provide for
the possibility to move the power tool body freely (see
fig. 8.2).
• Move the power tool body downward when the end
of the milling depth gauge 1 touches the stop lug 4 the
set milling depth will be achieved (see fig. 8.3). Tighten
the locking screws 2, while keeping the power tool
body in this position�
Milling direction
Milling should always be performed against
the router bit rotation direction� Otherwise,
the power tool will be subject to jerks, which
may result in the loss of control over it�
General operational recommendations (see fig. 9)
While in operation, be sure to use the
parallel guide 17 - this will provide for the
required control over the power tool.
• Mark out and fix the treated workpiece.
• Set the required milling depth and lock the power
tool body in this position, as described above�
• Adjust the parallel guide 17, as described above�
• Turn on the power tool�
• Hold the power tool using the handle with one hand
and hold the parallel guide 17 with the other hand (see
fig. 9).
• Perform the milling operation with a uniform ad-
vance, observing the recommendations concerning
