To prevent the workpiece or your fingers
from getting caught between the work plate
(12) and the sanding disc (11), the space
between work plate (12) and sanding disc
(11) must not exceed 1.6 mm.
The choice of sanding paper
With coarse sanding paper (P 60) generally most
of the material can be removed, and fine sanding
paper (P 150) is then used for finishing. An
uneven surface is first treated with coarse sanding
paper and sanded until it is even. Subsequently
medium-coarse sanding paper (P 100) is used to
remove the scratches caused by the first type of
paper used. Fine sanding paper (P 150) is used
for finishing. The sanding needs to be continued
until the surface is smooth.
The placing of the sanding paper
Fig. 6 - 9
When the sanding machine is held with the
sanding disc turned towards you, the sanding
belt moves from right to left along the upper part
of the machine. Because of this turning direction
the workpiece will be pressed against the right
side of the fence. An arrow on the inside indicates
the right direction of running of the sanding belt
(see drawing). If no direction is indicated, the
sanding belt must be placed in such a way that
the elevated part of the seam is placed into the
turning direction of the belt. So it is very important
that the sanding belt is placed in the correct
way. The machine uses standard 100 x 915 mm
sanding belts (nr 7):
• Remove the plug from the mains socket.
• Push the clamping handle completely to the
right to take away the tension of the transport
rollers (Fig.1: 14).
• Push the sanding belt along both of the
transport rollers, starting from the back of the
machine.
• Push the clamping handle completely to the
left. Now the sanding belt should be
completely tight.
• Turn the transport roller exactly in a right angle
to the direction of the sanding belts with the
use of the winged nut at the right roller. The
direction of running of the belt is adjusted
correctly if the sides of the sanding belt are
running parallel to the bearing plate.
The sanding disc
Paper or “velcro” plates are used for the sanding
disc. The standard diameter is 150 mm. The
plates are self adhesive.
Vertical placing of the sanding belt
For more flexibility of the sanding belt its bottom
side can be used, because there is no bearing
plate. For an easy reach of this bottom side the
sanding belt can be placed in vertical position.
• Loosen the two nuts at the front of the sanding
machine, around the left transport roller shaft,
with the use of an open-end spanner.
• Push the sanding belt up in the position
desired.
• Fasten the two nuts again.
• The workpiece can now rest on the worktop
instead of on the sanding belt;
• The work plate which is used for the sanding
disc can now be pushed with the shaft into the
hole of the machine frame, at the left side of
the sanding machine.
• Fasten the bolt at the back of the machine.
• The work plate can now be used as support
for the sanding of the work piece against the
sanding belt.
4. Putting the machine into operation
Switching On/Off
• Press the switch into position ‘1’ to put your
sanding machine into operation.
• To switch off the machine the same switch
needs to be pressed to position ‘0’.
• Always keep the mains cable away from
moving parts.
• There is no need to apply any pressure with
the workpiece, because this only slows down
the speed of the sanding disc.
Sanding
The sanding belt and disc supplied with this
sanding machine are suitable for the sanding of
metal, wood or synthetic surfaces. The workpiece
should always be held firmly during sanding. No
extra pressure is needed. Guide the work piece
up and down over the sanding belt, in order to
prevent the sanding belt and plate from wearing
through in one place. Round objects can be
sanded at the ends of the sanding belt. Work
pieces which are longer than the sanding machine
can be sanded by removing the fence.
