Virutex FRE317S, Operating Instructions Manual

5.3. Turning the motor body

When using the FRE317S as a angle trimmer, the machine 
must be set at an angle of 45º against its base (Fig. 1).
When using it as a router, the machine must be in an 
upright 90º position (Fig. 2).
Set the motor to the desired position by loosening the 
lock screws E (Fig. 1 and 2) with the Allen key, turning 
the motor until the head F (Fig. 1) is resting on the stop 
at the required angle and tightening the lock screws E.
Whenever working at an intermediate angle, use the 
scale J2 (Fig. 1) as a guide. This scale indicates the angle 
of the motor housing. Once the machine is set at the 
correct position, firmly tighten locking screws E.

5.4. Attaching cutting tools

Make sure the trimmer is not connected 

to the power supply before attaching the 

cutting tool.

Make sure the motor body is blocked by the lock screws 
E (Fig. 3) before inserting or removing the cutting tool.
Press the bit lock button G that keeps the motor axle 
from turning all the way down and loosen the chuck-
holder nut H using the spanner I (Fig. 3). The chuck 
and the chuck-holder nut fit together under pressure, 
so make sure the chuck is perfectly seated in the nut 
before inserting any tool.
Insert the cutting tool J (Fig. 3) for the job to be performed 
and, if necessary, place the reducer in the chuck-holder 
nut H. Firmly tighten the chuck-holder using the span-
ner, while holding lock button G down. No reducer is 
required when using a 12 mm o r 

½

” shaft bit. Always 

use the shortest possible bits to minimize bit decentring.
The bit, the chuck-holder nut and the reducer should 
be completely clean before assembly. 

Do not leave the machine without any tool 

as the chuck could become too tight and 

damage the shaft housing. Never start 

the machine when the bit lock button 

is pressed.

5.5. Locking the machine height

The machine can be adjusted to any height from the base 
by turning the locking lever K (Fig. 4) counter clockwise.
To lock the machine in a position of full safety, after 
fixing it in position with the locking lever K (Fig. 4), 
lock it between nuts L and M (Fig. 4), one above and 
the other below the body of the machine, and firmly 
tighten these nuts with their corresponding locking 
nuts, using the two spanners N (Fig. 4).

After performing any work, place the 

switch in the stop position and move the 

nut and locking nut L (Fig. 4) to the top 

limit and release the locking lever K (Fig. 

4) before leaving the trimmer on a flat 

surface. The built-in shock absorber will 

automatically make the motor return to 

its uppermost position when the lever 

is released.

5.6. Adjusting the depth

With the machine at the upper limit of its vertical run, 
and the front of the cutter bit flush against the wood 
surface, the routing depth can be adjusted up to 100 
mm. Unlock the depth rod O (Fig. 4) by loosening the 
fastening  knob P to lower or raise the depth rod O (Fig. 
4) and adjust it to the desired depth and once again lock 
the rod with the fastening knob P (Fig. 4).

PRECISION ADJUSTMENT.

 To adjust or correct the 

precision of the depth previously set, just turn the fine 
adjustment knob Q (Fig. 4). One complete turn of the 
knob represents the movement of the fine adjustment 
rod of 1 mm, with a maximum run of 5 mm. Each divi-
sion of the graduated fine adjustment indicator S (Fig. 
4) represents a movement of 0.1 mm.

5.7. Connecting the vacuum cleaner

To connect the machine to Virutex AS182K, AS282K, 
AS382L or ASC482U vacuum cleaners, or to another 
external collection source, one end of the suction tube 
included on the appliance should be connected at suction 
nozzle C2 (Fig. 4) on the machine and the other end to 
the external collection source chosen.
The power cable E2 (Fig. 19) can be fed through the 
brackets on the dust collection tube to make the machine 
easier to handle.

6. USE AS A CONCAVE RADIAL TRIMMER FOR RIMS

Designed for the trimming of concave radius in the 
rim joints of mineral worktops, it is equipped with an 
adjustable side guide T (Fig. 1) that prevents damaging 
the rim and allows for quick and easy trimming, pro-
ducing a perfect finish.
The bit is prevented from causing any damage to the 
material being worked by incorporating two extra 
protective R10 and R5 feelers U (Fig. 1). The machine 
can be safely guided using both the stop guide and the 
adjustable guide (Fig. 5).

6.1. Preparing the rim

Attach the rim correctly by adding a part between the 
worktop and the rim edge to create a concave bottom 
with no visible joint after trimming. The size of the 
intermediate part will depend on the desired radius as
