Virutex FR278R Gebrauchsanweisung Seite 9

Always use router bits of such diameters that
correspond the lock collet. The number of re-
volutions must not be higher then the allowed
speed of the router. It is forbidden to use
router bits of diamenters larger than 40 mm.
Carbide tipped bits (HM) are suitable for working hard
materials and enable higher cutting speeds.
11. CLAMPING ROUTER BITS
Always disconnect the plug from power
source before making any adjustments
or changing any accessory.
Clamp the bit with the collet 25 (Fig. 1) and the nut 13
(Fig. 1). The correct order for clamping bits:
• Unscrew the nut with the inserted collet on the spindle
by 1-2 threads.
• Insert a bit. The bit must be inserted at least 20 mm
deep. Pushing the lock-off button 12 (Fig. 1, 4) you block
the spindle, and then fasten the clamp nut 13 (Fig. 1)
with the fork wrench 23 (Fig. 1). Excessive fastening of
the nut can damage the thread on the spindle.
• Never drive in the clamp nut 13 till the end of the
shaft when there is no bit in the collet. Danger of
damaging the collet!
When removing the bit with one turn, first loosen the
clamp nut 13 (Fig. 1), and then continue unscrewing it
till the bit is completely loose.
12. CHANGING CLAMPING COLLET
Collet must be fixed in the clamp nut 13 (Fig. 10). When
you want to change it, pull it from the nut using a small
screwdriver which you insert between the nut and the
collet. Insert a new collet with a strong push into the
clamp nut (click).
Collet must be inserted in the nut in such
manner that the nut and the collet are
even at the front side.
13. FIXING ROUTER TABLE
Fix the router table to the desired height by the lever
24 (Fig. 5). Built-in telescopic spring returns the router
table in the original position after releasing the lever.
14. ROUGH DEPTH ADJUSTMENT
Always disconnect the plug from power
source before making any adjustments
or changing any accessory.
Set the depth of milling by the screws on the chip
deflector 16 (Fig. 6), together with the adjusting bit
10 (Fig. 6) by indicator 28 (Fig. 6). the three screws on
the chip deflector enable pre-setting of three depths
of milling. The range of setting is 50 mm.
Put the rpiter on the workpiece.
Release the lever 24 (Fig. 5) and slowly push down the
tool. When the router touches the surface, pull the
lever 24 (Fig. 5).
Turn the chip deflector 16 (Fig. 6) to the most favourable
depth of milling.
Unscrew the wing screw 11 (Fig. 6) and thereby you
loosen the movement of the adjusting bit 10.
Push down the adjusting bit 10 (Fig. 6) so that it is set
on the screw on the chip deflector.
Set the depth indicator 28 (Fig. 6) to 0.
Push the adjusting bit 10 (Fig. 6) upwards. When you
reach the desired depth on the scale 7 (Fig. 6), fasten
the wing screw 11 (Fig. 6).
Release the lever 24 (Fig. 5) and push the bit into the
new preadjusted position so that the adjusting bit 10
(Fig. 6) is laid on the screw and then pull the lever 24
(Fig. 5) again.
You must check the rough depth adjustmnet by a practical
test and then correct it if necessary.
15. FINE DEPTH ADJUSTMENT
Always disconnect the plug from power
source before making any adjustments
or changing any accessory.
Carry our fine depth adjustment if necessary. Having
set the rough depth adjustment you can set the desired
depth to 0.1 mm accurately by turning the knob of the
adjusting bit (1 line = 0.1 mm).
First release the lever 24 (Fig. 5). While you are pushing
the tool down, press the upper button of the adjusting
bit in the direction G (Fig. 6), so that it is laid on the
screw on the revorverskem nastavku 16 (Fig. 6). Adjust
the lower button with the upper one, then turn the
upper button in the direction H for a desired value. Pull
again the lever 24 (Fig. 5)
16. FINE DEPTH ADJUSTMENT WITH
THE ROUTER FIXED IN A TABLE
Support the adjusting bit 10 (Fig. 6) on the screw of the
chip deflector by a hollow screw and a spring.
Fasten the hollow screw 14 (Fig. 6) to the adjusting bit
