VI - Operation
These models SPARKY power tools are supplied from
single-phase alternating current mains. They are double
insulated according to EN 60745, IEC 60745 and can be
connected to grounded or not grounded sockets. This
power tool is radio suppressed in compliance with EMC
Directive 2004/108/EC.
PRIOR TO INITIAL OPERATION
WARNING: Make sure power supply voltage
corresponds to the value indicated on the name plate
with technical data of the tool.
▪ Always check the position of ON/OFF switch. The
power tool must be connected to the power supply
socket only when this switch is in OFF position. If the
plug is connected to a receptacle while the power
switch is in the ON position, the power tool will start
operating immediately, which could cause a serious
accident.
▪ Make sure the cord and the plug are in order. If the
replacement of the supply cord is necessary, this has
to be done by the manufacturer or his agent in order
to avoid a safety hazard.
SWITCHING ON - SWITCHING OFF
Brief activation: (Fig. 1)
Switching on: press ON/OFF switch (9).
Switching off: release ON/OFF switch (9).
Continuous use: (Fig. 2)
Switching on: press ON/OFF switch (9) and in pressed
position lock it by button (11).
Switching off: press ON/OFF switch (9) once and re-
lease it immediately.
ATTACHING A SANDING BELT
WARNING: Switch off the sander and dis-
connect it from the power point
1. Pull the belt tension lever (6) and slide off the old belt.
(Fig. 3)
2. Check that the replacement belt has a good join and is
not frayed at the edges.
3. Slip the new belt into position with the rotation arrow
on the inside of the belt pointing in the same direction
as the arrow on the sander. (Fig. 4)
4. Fold down the lever (6). (Fig. 5)

5. Plug the sander into a power point and with the sander
held tight, pull the trigger on/off switch (5) and allow
the belt to rotate for a short period.
6. Whilst the belt is running, adjust the tracking knob (13)
to align the belt to the centre of the roller (8). (Fig. 6)
7. Repeat the trigger action and tracking adjustment until
the belt is correctly aligned.
8. Run the sander for a minute or so to ensure correct
alignment before using the sander on a work piece.
WARNING: Do not continue to use the sand-
er with a sanding belt that is overworn or damaged.
WARNING: Do not use the same sanding
belt for wood and metal. Metal particles become em-
bedded in the belt and will scour a wooden surface.
SELECTING THE RIGHT GRADE OF SANDING
BELT
1. Different grades of sanding belt can be purchased
from your local hardware store. Typical grades are
Coarse (40 grit), Medium (80 and 100 grit) and Fine
(120 grit).
2. Use Coarse grade to remove rough finishes, Medium
grade to smooth the work and Fine grade to finish it
off.
3. It is best to make a trial run on a scrap piece of ma-
terial to determine the optimum grades of belt for a
particular job.
4. In order to take full advantage of your sander, always
purchase good quality belts.
NOTE: After sanding with a belt sander, an orbital sand-
er should be used to give a better surface finish.
PRE-SELECTING THE BELT SPEED
(MBS 1100Е)
The necessary belt speed can be pre-selected with elec-
tronic regulator thumbwheel (4), even during operation.
The optimum belt speed depends on belt grit and pro-
cessed material and can be determined through experi-
ence.
Recommended speed values are shown in the table on
page 84.
SANDING
1. These sanders are designed for sanding wood,
metal, plastic and similar materials. They are used
mainly for quickly removing a large amount of mate-
rial. Do not use these sanders for sanding magne-
sium.
2. Ensure that the belt is in good condition and fits
properly.
3. Plug in the tool to the power socket.
4. Adjust the necessary speed by rotating the regula-
tor thumbwheel (4) (for MBS 1100Е only). The maxi-
mum speed corresponds to the symbol G, and the
minimum speed - to symbol A. Sanding efficiency
and surface quality are determined by belt grade
and speed. The higher the belt speed, the more ma-
