Operational Tips - Valex F401V Instrucciones Originales

Assemble the parts of the parallel milling guide (Fig. A Pos.
11) as shown in Fig. H. Place the slot (1) under the wheel
(2) and, before tightening, position the guide at the required
height, in relation to the milling base.
Slacken the wind nuts (3) to allow you to move the guide
closer to or away from the milling cutter's axis. When properly
set, tighten the wing nuts (3) and the wheel (2).
Fig. L illustrates the use of this accessory.
gUIDE fOR CIRCULAR MILLINg (fig. M)
The parallel milling guide can also be used for circular milling.
Disassemble the guide fitted previously and put it together
again as shown in Fig. N. The bolt and wing nut can be
placed in either of the two holes in the rod, depending on the
milling radius required. Fit the guide to the milling machine
again as indicated in the previous paragraph. Put a bolt (1)
into the free hole and tighten it at the centre of the circle to
be formed. Slacken the bolt and wing nut (2) and move the
milling machine to the required radius. Tighten the wing
nuts carefully.
ADJUSTAbLE PROfILE COPYINg gUIDE (fig. P)
Fit this accessory (Fig. A Pos. 12) by inserting the rod with
the slot (1) under the accessory clamping wheel (2). To
adjust the position of the guide bearing (3) in relation to the
milling cutter fitted and the work to be carried out, slacken the
wheel (4) and rotate wheel (5) to obtain the working position.
Tighten wheel (4) carefully. Set the axial distance between
the guide bearing (3) and the milling tool, by moving the rod
(1). When setting is complete, tighten the wheel (2) carefully.
Fig. Q illustrates how to use this accessory.
fIXED PROfILE COPYINg gUIDE (fig. R)
Remove all the accessories excepting the milling support base
(Fig. A Pos. 7). Remove the screws (1) and the base cover
(2). Insert the guide (3) in the seating (4) in the fixed base
(5). Refit the cover (2) and screws (1) tightening them well.
This accessory is used for copying an existing profile. A 6
mm diameter milling cutter is to be used with this accessory.
The external diameter of the profile copying guide is 10mm.
This means that the difference between the profile being
copied and the work to be done is 2 mm (6).
Fig. S illustrates the use of this accessory.

OPERATIONAL TIPS

Read the safety regulations carefully and follow them scru-
pulously to gain the best possible performance from your
milling machine.
If you work calmly after having acquired a good knowledge of
the tool, you will be able to make full use of the tool's potential.
- Only start the machine when you have a firm grip on it and
rest it on the work piece.
- Work at a steady pace. Be careful when milling is about
to be completed. Hold the tool tightly to avoid it slipping
from your grasp when there is no more resistance from the
material being worked.
- Before carrying out final work, do a few tests to check that
the tool used and the depth set are correct.
- Check the direction of rotation of the milling cutter, and
choose the most suitable working direction (see Fig. T).
- For straight runs always use a straight edge suitably fixed
to the work piece (see Fig. U).
- Do not overload the machine, carry out light work using a
number of strokes.
- Always keep the milling cutters sharp.
- Make sure the work piece is properly secured.
MAINTENANCE
WARNINg! Always unplug the tool from the mains
socket before proceeding with any sort of inspection or
maintenance jobs.
- Take good care of your tool and clean it regularly. In this
way its efficiency will be ensured and its lifespan extended.
- While working with the tool and on finishing work, clean
the ventilation slots carefully.
- Clean the tool using a cloth.
- Do not wet or spray water over the tool.
- Do not use detergents or other solvents to clean the tool as
you could irreparably damage it. Chemical agents easily
damage the plastic parts.
- For repairs and maintenance not covered in this handbook,
contact an authorised assistance centre.
REPLACINg THE CHUCK (fig. C)
Slacken the screw (1) and remove the support (3) from the
machine casing (2). Using the 10 mm spanner (4) hold
the motor's shaft steady and use the 17 mm spanner (5)
to remove the nut (6). Remove the chuck from its seating
and fit the new one. Refit the nut (6). Do not fix it without
having inserted a milling cutter. Refit the support (3) on the
machine casing (2) and tighten the screw (1).
SPARES
When parts are broken or need replacing contact an autho-
rised service centre.
TROUbLE SHOOTINg
If the milling machine fails to start: check if all the electrical
connections are firmly plugged into the mains; check if the
trip switch has tripped; check if a fuse has blown in your own
electrical system. If the problem persists following these
checks then the problem could be in the machine so have
an authorised service centre check it.
- While working the motor slows down – reduce the advan-
cement pressure, check that the milling cutter is sharp, and
sharpen it if necessary.
- The motor overheats – reduce the advancement force;
check the sharpness of the milling cutter and sharpen if
necessary; replace the milling cutter with one that is suitable
for the type of work being done.
STORAgE
Follow the tips below to store the tool:
1) Clean the tool and all its accessories thoroughly (see
maintenance section).
2) Store the tool:
- Out of reach of children.
- In a stable and safe position,
- In a dry and cool place,
- Avoid excessively high or low temperatures.
3) Protect the tool from direct light, if possible keeping it in
the dark or semi-dark.
4) Do not close it in nylon bags where humidity could be
produced
