Vibration level
The vibration emission level stated in this instruction manual has been
measured in accordance with a standardized test given in EN 60745; it may be
used to compare one tool with another and as a preliminary assessment of
exposure to vibration when using the tool for the applications mentioned
- using the tool for different applications, or with different or poorly maintained accessories, may significantly increase the exposure level.
- the times when the tool is switched off or when it is running but not actually doing the job, may significantly reduce the exposure level.
- Protect yourself against the effects of vibration by maintaining the tool and its accessories, keeping your hands warm, and organizing your work patterns.

ASSEMBLY
Installation
Avoid the use of long extension cables. Do not forget to leave enough space
around the machine for the workpieces to be sanded.
Assembly
-
Put the machine frame on its head and press the four rubber stops into the foot of the frame.
-
Machine frame, aluminium disc (10) and work plate (12) are supplied in separate packaging.
-
Push the aluminium disc on the shaft and fasten the disc with the socket bolt on the side of the disc (Fig.B,D)
. -
Place the work plate (12) with the shaft in the machine frame and secure the work plate with the bolt on the side of the machine frame. Check with a 90° sash angle on the work plate and against the sanding disc if the angle is exactly 90° (Fig.E).
-
If necessary, adjust this angle with the calibration indicator.
-
The mitre scale (13), which is also supplied separately, can be placed on the work plate
(12). With the use of this mitre scale the angle of grinding can be determined precisely. -
The fence (8) for the belt sander can be placed behind the uppermost bolt of the V-belt guard. In this way, the workpiece can be held firmly against the belt, without great hazards.
-
Attach the vacuum cleaner to the vacuum cleaner connections (15)
To prevent the workpiece or your fingers from getting caught between the work plate (12) and the sanding disc (11), the space between the work plate (12) and the 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. F – H
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 in 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 (6)
- Remove the plug from the main socket.
- Push the clamping handle completely to the right to take away the tension of the transport rollers (4).
- 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 at 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
Fig. D
Paper or “velcro” plates are used for the sanding disc. The standard diameter
is 150 mm. The plates are self-adhesive.
The vertical placing of the sanding belt
Fig. I
For more flexibility in the sanding belt, its bottom side can be used, because
there is no bearing plate. For easy reach of this bottom side, the sanding
belt can be placed in a 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 workpiece against the sanding belt.
OPERATION
Always stand facing the machine so that you always have a good overview (Fig.
A).
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
workpiece 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. Workpieces that are longer than the sanding
machine can be sanded by removing the fence.
NB: To prevent splintering, wood always needs to be sanded in the
longitudinal direction of the grain.
To treat a very soft surface, there is a very handy method to ‘bring the
particles to the surface. This is done as follows: wet the already sanded
surface with a cloth or sponge and let it dry well. Some wood fibres will
swell up more than others, which leads to a rougher surface than before. Now
the higher particles are treated with fine sanding paper, the result is a
remarkably smooth surface. This method should not be applied with varnished
wood, however, because the varnish may come loose because of the moisture.
MAINTENANCE
Before cleaning and maintenance, always switch off the machine and remove the
main plug from the mains. Clean the machine casings regularly with a soft
cloth, preferably after each use. Make sure that the ventilation openings are
free of dust and dirt. Remove very persistent dirt using a soft cloth
moistened with soapsuds. Do not use any solvents such as gasoline, alcohol,
ammonia, etc. Chemicals such as these will damage the synthetic components.
Replace power cords
If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons in order to avoid a hazard.
Mains plug replacement (the UK only)
If the moulded 3-pin plug attached to the unit is damaged and needs replacing,
it is important that it is correctly destroyed and replaced by
an approved BS 1363/7A fused plug and that the following wiring instructions
are followed. The wires in the mains cable are coloured in accordance with the
following code:
- blue neutral
- brown live
As the colours of the wires in the mains cable of the unit may not correspond to the coloured markings identifying the terminals in the plug, proceed as follows:
- The wire which is coloured blue must be connected to the terminal which is marked with the letter N or coloured black.
- The wire which is coloured brown must be connected to the terminal which is marked with the letter L or coloured red.
ENVIRONMENT
Faulty and/or discarded electrical or electronic apparatus have to be collected at the appropriate recycling locations.
Only for EC countries
Do not dispose of power tools into domestic waste. According to the European
Guideline 2012/19/EU for Waste Electrical and Electronic Equipment and its
implementation into national right, power tools that are no longer usable must
be collected separately and disposed of in an environmentally friendly way.
