Fold the protective cap away to the side. Press the
tensioning arm (H) against the housing and remove the
slackened sanding belt via the sanding arm roller (I) (see
Fig. 4).
During assembly, place the sanding belt around the drive
roller (J) and over the deflection rollers (K). Tighten the
sanding belt with one finger, press the tensioning arm (H)
against the housing, pull the sanding belt over the
sanding arm roller (I) and release the tensioning arm (H).
After changing the sanding belt, close the protective cap
again.

Slightly loosen nut (T) and screw (S), then push the
sanding arm backwards. Secure again with the screw
(S). After inserting the sanding belt, loosen the screw (S)
slightly so that the sanding belt is tensioned. Lock this
position with the nut (T). With the machine running,
adjust the belt run with screw (U) and lock the setting with
screw (V) (see Fig. 6).
ATTENTION:
If the sanding belt breaks, the deflection roller of the
sanding arm can move in the groove. When the machine
is next put into operation, it must be ensured that the
deflection roller is pressed in as far as the stop in the
sanding arm (see Fig. 10, cut-out stop).

and place the sanding belt over the drive roller (M) (see
