Cleaning and maintenance

Remove the panel from the bottom.

Check idle position of the electrode dedusting

There is a mark on the washer on the electrode
dedusting drive wheel which marks the idle position of
the electrode dedusting.

Fig. 2-33: Idle position mark

Through the maintenance opening on the top,
inspect whether the lever gear teeth can support

the striking weight in idle position. The gap must be 3

mm. If not, the delay time (= parameter [Electrode

dedusting delay]) must be adjusted in the control
system.

Fig. 2-34: Idle position

Check the idle position of the sliding rakes

A screw is located on every sliding rake drive wheel
which actuates the position switch for the idle position
of the sliding rakes.

Fig. 2-35: Screw for the position switch

Through the maintenance opening on the top,
check whether the sliding rakes lie flush against

the bottom stop in the idle position.
