Mounting the abrasive belt
Prepare the abrasive belt with the dimensions given in the table.
Raise the tension lever (II) to reduce the distance between the belt tension rollers. Apply the abrasive belt so that the arrow points
showing the direction of the belt movement, seen on the grinder housing and on the belt, are consistent (II).
Lower the tension lever and align it with the grinder housing (III).
Perform a test run on the grinder. Make sure that the grinder switch is not in the "on" position. Press it and release.
Plug the power cord plug into the socket. While holding the grinder with both hands so that the belt does not come into contact
with any surface or object (V), press and hold the on/off switch.
If the tape starts to move along the rollers, this means that the rollers are not parallel. If this happens, release the pressure on the
switch, wait for the belt to stop, unplug the power cord from the socket, and adjust the position of the rollers using the knob (III).
Restart the grinder according to the procedure described above.
The adjustment should be made until the rollers are parallel and the belt does not move along the rollers when the grinder is
running.
Connecting the dust extraction (IV)
The grinder is equipped with an extraction system to collect dust generated during operation. Place the bag supplied with the
grinder in the dust extraction opening. An external dust extraction system, e.g. based on an industrial vacuum cleaner, can also
be connected to the connector.
Caution! It is not recommended to connect to the regular household vacuum cleaner connectors. Such vacuum cleaners are
not equipped with fi lters capable of handling industrial dust. Using a household vacuum cleaner to extract dust can damage the
device. The adapter for connecting an external dust extraction system to the tool is not included with the product.
Starting and stopping the grinder
Make sure that the grinder switch is not in the "on" position. Press it and release.
Plug the power cord plug into the socket. While holding the grinder with both hands so that the belt does not come into contact
with any surface or object (V), press and hold the on/off switch. Run the grinder for approx. 30 seconds. During this time, check
whether no suspicious sounds are coming from the grinder, that the grinder does not vibrate excessively and that the belt does
not slip off the rollers. If no irregularities are found, the work can be commenced.
Caution! The grinder on/off switch is equipped with a lock which can be used to block the pressed on/off switch for long periods
of operation. The lock button must be pressed while the on/off switch is pressed, then the pressure on the on/off switch and the
lock button can be released. Release the lock by pressing the on/off switch again.
The grinder stops when the pressure on the unlocked switch is released. The belt may still rotate for some time after the switch
is released.
Working with grinder
Before the start of work fi x the workpiece so that it cannot displace unexpectedly in the course of work. You may use for this
purpose hand screws, vices, chucks etc. Apply the grinder at full speed to the surface of surface processed. Belt should travel
at full speed.
Grinder to be handled with both hands when being moved on the surface of processed material. Grinder's movements should not
be fast. When processing wooden surfaces the grinder should be moved along the grains.
Do not exert excessive pressure on the grinder; the weight of the grinder is suffi cient for the processing of workpiece. Excessive
pressure leads to premature wear of the abrasive belt and may lead to damaging of the processed surface, does not aff ect the
speed of the grinder.
Speed of belt's travel should match the type of the processed surface and the type of abrasive belt. Higher belt's travel speed
results in faster and more precise processing. The higher (fi ner) grit of abrasive belt, the lower but more precise processing. The
condition of belt should be checked in the course of work, worn or damaged belt should be replaced with new one before restart
of work.
Never use the previously used belt for the processing of other type of surface. For example the tape used previously for the
processing of metal surface should not be used for the processing of wood.
It is forbidden to use the grinder in other way than the tool operated using hands of the operator. Do not use the grinder as station-
ary tool affi xed to e.g. table by means of clamps. Grinder has not been designed for such a use and using it as the stationary tool
poses a serious threat of injuries to operator.
If the grinder is used for removal of varnish coating, it should be fi tted with dust extraction system and lowest pressure should be
applied during the work. Excessive pressure may lead to heat generation and consequently to dissolution of varnish coating. This
will lead to contamination and premature wear of abrasive belt as well as it may contaminate the material being processed.
Additional notes
Declared total value of vibration was measured by means of standardized test method and can be used to compare one tool with
the other. Declared total value of vibration can be used in the initial exposure assessment.
Warning! Emission of vibration when working with the tool may vary from the declared value, depending on how the tool is used.
Warning! It is required to determine safety measures to protect the operator, which are based on the exposure assessment in
