3. Push the clamping lever
back to its original position.
Manually adjusting the abrasive belt
:
If the abrasive belt does not run centrally after switching on, you will have to adjust the belt
tracking manually.
♦♦ To do this, turn the adjusting screw
on the front roller until the abrasive belt
runs centrally.
IMPORTANT: It is imperative to ensure that the abrasive belt
does not rub against the hous-
ing.. Check the belt tracking regularly, and readjust it using the adjusting screw
if necessary.
Working procedures
A lower sanding pressure is sufficient:
■■ apply minimal sanding pressure when working.The own weight of the belt sander own
weight is sufficient for good sanding performance.. This method further allows you to reduce
wear on the abrasive belt
, and the surface of your work-piece will be smoother.
Removal and surface:
■■ The abrasive performance and the surface quality are determined by the belt speed and the
grain size of the abrasive belt
(see also Section "Selecting speed and abrasive belt").
Sanding process:
■■ Switch the appliance on, place it on the work-piece and work with a moderate forward
move-ment. Run the sander in parallel and overlapping sanding motions over the workpiece..
Only sand in the direction of the grain to avoid transverse scratches. After completing the task,
lift the appli-ance from the workpiece and then switch it off.
NOTE
►► Always hold the appliance firmly with two hands while working..
Dust extraction
WARNING! EXPLOSION HAZARD!
■■ In environments with an explosive dust / air mixture, please use a specially-designed
extraction appliance.
RISK OF FIRE DUE TO FLYING SPARKS! When sanding metals do not use dust extraction (dust
box
or vacuum cleaner).
■■ Materials containing asbestos may not be pro-cessed.. Asbestos is a known carcinogen.
WARNING! RISK OF FIRE!
■■ Working with power tools that have a dust col-lection box or can be connected to a
vacuum cleaner via the vacuum cleaner adapter causes a risk of fire! In unfavourable condi-
tions, e.g. when sparks are flying while sanding metal or metal residues in wood, wood dust
in the dust box (or in the vacuum cleaner dust bag) can spontaneously ignite. This is a particu-
lar risk if the wood dust is mixed with paint residues or other chemicals and the workpiece has
become hot after being worked for a long time.. Therefore, do not allow the workpiece to
overheat and always empty the dust box or the dust bag of the vacuum cleaner before taking
a break from work.
