Valex LND 127 Instruction Manual And Safety Instructions page 15

If you notice any working defects, switch off the machine
and consult the chapter "troubleshooting and permitted
operations".
STOPPING
To stop the machine, press the OFF "O" switch (pos. 1).
When not using the machine, turn it off and disconnect the
plug from the socket.
The machine is equipped with a device that prevents sudden
starts after a power outage during machine use. Press the
switch to start.
OPERATING WARNINGS AND TIPS
WARNING! Before conducting checks and adjustments, turn
the switch to the OFF "O" and unplug the machine from the
electric power supply.
After having read the previous chapters carefully, apply these
tips scrupulously to obtain maximum performance from your
machine. Proceed with caution. You will only be able to make
full use of the machine's potential after gaining sufficient
experience. Acquaint yourself with all controls. Run trials
without work pieces.
OPERATOR
The normal operator position is in front of the belt or disc,
using both hands to hold the piece. This is the only position
possible for sanding.
Warning! Keep hands and face away from the abrasive tool,
serious injury hazard!
WORK PIECE
The shape, size and weight of the piece must be compatible
with the machine.
Warning! For your safety, it is important that the piece
is correctly locked. Do not sand circular sections, old or
fragile wood, irregular wood, cracked wood, wood with
nails or screws, branches or trunks. Always carefully
inspect the piece.
ABRASIVE TOOLS
Make sure the abrasive tool is whole, without cracks or de-
formations, before use.
When necessary, replace it following the instructions in the
following chapters.
Warning! Tool efficiency and perfect integrity provide better
results and minimize accident risks.
CHIP AND DUST VACUUM
The machine is equipped with a manifold for the belt (pos.11)
and one for the disc (pos.5), to vacuum chips/dust. Please
remember that the part of material removed while sanding will
also be thrown around the machine and on the piece.
Connect the manifold (pos.11 e pos.5) to a wood chip/dust vacuum
using a flexible plastic hose (neither supplied with the machine);
your local dealer can recommend the best product.
Warning! Do not start the machine if the vacuum tube is not
installed. Do not insert your fingers or tools in the manifold
in the attempt to remove material. Serious injury hazard!
WORK
The motor provides power to rotate the belt using a wheel unit
and to rotate the disc.
The work piece must rest against the work surface (pos.3-9),
while the tool (pos.2-8) is running. Gradually and carefully
move the piece against the tool and press down slightly to
remove material. Make light passages frequently checking
results on the piece.
The machine can sand at 0° to 45° angles; to change the work
surface angle, loosen the levers (pos.7 or pos.15), tilt the
surface (pos.3 or pos.9) and lock the levers.
To avoid abnormal belt abrasive wear, slightly move the piece
back and forth across the entire belt.
Only work on the left hand part of the disc (fig.E), so that the
piece moves along the work surface.
Always observe the following warnings:
- make sure that levers and screws are tightened to firmly
secure mobile parts
- keep the work piece firm
- the piece must rest against the work surface
- do not sand several pieces simultaneously
- keep safety distance from the sanding area
- gradually and carefully near the piece to the abrasive tool
- do not overload the abrasive tool so as not to overly strain
the machine
- excessive strain causes faults
- do not start the machine if the piece is in contact with
the abrasive tool
- do not start the machine if the abrasive tool guards are
not in place
- do not start the machine without the work surface
- to clean the work area, use a brush with a long handle
ABRASIVE TOOLS
Use good quality abrasive tools with the same characteristics
as the machine based on its technical data – your retailer will
be able to help you make the correct choice. Also observe any
instructions provided with the equipment.
The dimensions must be equal to those shown on the ma-
chine.
Use abrasive tools which conform to the regulations in force
in the country of use.
Always carry out a simple visual check: there must be no
deformations, breakages or damages.
Our company provides a complete series of belts and discs
suitable for your machine, which you can buy from your
retailer.
ABRASIVE TOOL REPLACEMENT
WARNING! Before replacing parts, turn the switch to the
OFF "O" and unplug the machine from the electric power
supply.
WARNING! Use gloves to prevent serious injuries.
WARNING! The assembly of the abrasive tool must be
carried out with absolute precision. Incorrect assembly
causes very serious danger.
When replacing the blade, proceed as follows. The operation
must be carried out by an expert; if in doubt please contact
an authorised service centre.
