5. Initial Operation

Before plugging in, check that the rated mains
voltage and mains frequency, as stated on the
rating label, match with your power supply.
Always install an RCD with a max. trip current
of 30 mA upstream.
Attaching the additional handle
Always work with the additional handle
attached (10)! Attach the additional handle on
the left or right of the machine and secure. Attach
the additional handle to the side facing away from
the sanding belt (6).
Turning the sanding head (8) to operating
position
Note: To turn the clamping lever (9) the position of
the lever must be changed
if necessary. The position can be changed without
clamping. For this purpose, raise the lever, turn it
and then lower the lever again.
- Release clamping lever (9).
- If necessary and depending on the working
conditions, turn the sanding head (8). The sanding
head must be positioned in the permitted working
area as shown (see illustration A, page 2).
- Firmly tighten the clamping lever (9).
- The clamping lever (9) is tongued. If you pull it out
slightly, it can be turned on the hexagon
underneath.
Each time before you start work, verify that the
clamping lever (9) is sufficiently tightened to
ensure that the sanding head (8) does not move.
Otherwise, the sanding belt (6) may come in contact
with the user. Loss of control can cause personal
injury.
6. Use
6.1 On/Off switch, continuous activation
Always guide the machine with both hands.
Switch the machine on first before mounting it
on the workpiece.
The machine must not be allowed to draw in
additional dust and shavings. When switching
6
the machine on and off, keep it away from dust
deposits.
After switching off the machine, only place it
down when the motor has come to a standstill.
Avoid inadvertent starts: always switch the
tool off when the plug is removed from the
mains socket or if there has been a power cut.
In continuous operation, the machine
continues running if it is forced out of your
hands. Therefore, always hold the machine using
the handles provided, stand in a safe position and
concentrate.

switch (11) and release.
6.2 Setting belt speed
The belt speed can be preset via the setting wheel
(12) and is infinitely variable.
Positions 1-6 correspond approximately to the
following belt speeds:
1 ........ 9,0 m/s
2 ........ 12,6 m/s
3 ........ 15,0 m/s
6.3 Sanding belt replacement
See illustration B, page 2.
- Manually loosen screw (5) and remove cover (3).
- Pull tensioner arm (7) backwards and remove
sanding belt (6).
- Place the new sanding belt on the rollers such that
its direction of circulation (arrows on the inside of
the sanding belt) matches the arrows (4) on the
cover. Place the sanding belt first on the drive
shaft and then on the roller on the sanding
attachment (1).
- Replace the cover (3) and tighten the screw (5) by
hand.
- Check the belt run and adjust if necessary (see
