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 (VI), 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 (VI), 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.
Belt speed control (V)
The grinder allows for an infi nite belt speed adjustment by means of a knob. The higher the number visible on the knob, the higher
the belt speed. Limit speeds have been provided in the table below.
Adjusting the position of the additional handle (VII)
The grinder handle can be set in one of three positions. This allows to adjust the grip of the grinder to the physical conditions of
the operator and/or the type of work. Pull the lever which locks the position of the accessory bracket back and then change the
position of the handle. It is possible to set the handle in one of the three positions indicated by the sound of the ratchet mechanism.
Closing the locking lever locks the handle in the set position.
Warning! It is forbidden to use the grinder without the additional handle locked.
Lifting the housing front (VIII)
The grinder allows the front of the housing to be raised, which in combination with the small diameter of the front roller tensioning
the belt enables sanding places inaccessible with a traditional belt grinder, such as inside corners.
Set the additional handle in the top or middle position and then lift the front of the housing completely. The ratchet mechanism will
hold it up. The front part is lowered by pushing it forward.
Warning! It is forbidden to operate with the front part of the housing raised where not necessary.
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
