4.4 Cooling air
Position the air guide fl ap (1.1) so that the escap-
ing air does not disturb you.
5 Working with the machine
- Only switch off the machine when lifted from the
workpiece.
- Only guide the machine along the workpiece
when switched on. Only switch off the machine
once you have lifted it off the workpiece com-
pletely.
- Before putting the machine down, always switch
it off and wait until it has stopped completely.
- Always secure the workpiece in such a manner
that it cannot move while being sawed.
- The machine must always be held with both
hands by the designated handles (1.4, 1.5).
Metalworking
The following precautions are to be taken
when processing metals for safety rea-
sons:
- Pre-connect a residual current circuit-breaker
(FI, PRCD).
- Connect the machine to a suitable dust extractor.
- Clean tool regularly of dust accumulations in
the motor housing.
- Wear protective goggles.
- Sanding metal generates fl ying sparks. Make
sure that sparks do not pose a risk for other
persons. Flammable materials located within
the range of fl ying sparks pose a fi re hazard and
should be removed immediately.
Operating instructions
Apply minimal pressure when working with the
machine. The weight of the machine should be
suffi cient.
Work at a steady pace. Guide the machine in
parallel, overlapping sanding strokes along the
workpiece. Sand in the direction of the grain to
achieve a better surface quality.
When sanding paint, clean the workpiece surface
regularly so that paint dust does not clog the
sanding belt.
Once used on metal surfaces, sanding belts
should not be used on any other material.
5.1 Stationary use (partly accessories)
- Attach both feet (5.3) via the two threaded holes
(4.6). Important: the straight edges of the feet
must face inwards.
- Make sure that the machine is standing fi rmly:
use clamps to attach the feet to the base.
5.2 Longitudinal stop (partly accessories)
- Attach the longitudinal stop to the threaded hole
(5.2) using screw (5.1).
- Unscrew the screw (6.3) to adjust the position
of the longitudinal stop along the sanding belt.
- To sand sloping surfaces, unscrew the screw
(6.2) and adjust the longitudinal stop. The scale
(6.1) indicates the angle setting.
5.3 Sanding frame (partly accessories)
Assembly
- Position the machine so that the sanding frame
tenons (2.3) rest in the grooves (2.4). The coun-
terpiece (2.2) on the height adjuster must rest
underneath the spring (2.1).
- Push the machine downwards towards the
grooves (2.4) until the counterpiece (2.2) latches
into position.
Removal
- Push the knurled screw (2.7) downwards until
the counterpiece (2.2) pops out of the notch.
- Remove the machine from the sanding frame.
Note: the position of the sanding frame guide
elements (2.4) is set in the factory. Do not detach
them from the machine!
Working with the sanding frame
Adjust the height of the sanding frame using the
knurled screw (2.7). Increase the cutting depth
(the distance the sanding belt protrudes over the
edge of the sanding frame) by turning the screw
in the direction of the plus sign. One turn of the
knurled screw corresponds to 0.4 mm.
Practical hint: use a test workpiece to set the
sanding frame to the correct cutting depth.
When work is complete, push the eccentric clamp
(2.6) towards the machine until it latches into
position. The machine is raised above the work-
piece. When you return the eccentric clamp to its
original position, the preset cutting depth is the
same as before.
6 Maintenance and care
Always remove the power supply plug
from the socket before carrying out any
work on the machine.
All maintenance and repair work which
requires the motor casing to be opened
may only be carried out by an authorised
service centre.
