14 Troubleshooting
Problem Possible causes Remedy
PLANEX bumps over
the surface. Suction power too strong Reduce suction power or switch to external
extraction if necessary.
Hard repair compound or hard sub-
layers Reduce suction power or switch to external
extraction if necessary.
Reduce speed.
Extraction power is
insuffi cient. Filter element on
CTL/M 36 E AC PLANEX blocked /
clogged. Clean the fi lter element regularly:
Option 1: Set the suction power control to the
maximum setting. Cover the nozzle, suction
hose or intake opening on the extractor with

cally (extracting).
Option 3: Check the fi lter element for dam-
age and clogging. Insert a new fi lter element
regularly.

extraction control on setting 1 Increase suction power or switch to external
extraction.
Repair compound with a high percent-
age of fi ller, soft fi ller Switch on the external extractor connected to

ting 6, in extreme cases, turn down the speed.
Suction hose blocked or kinked. Remove blockage and straighten hose.
Disposal bag full Dispose of the bag.
Excessive material

the PLANEX, set the extraction control to set-
ting 6, in extreme cases, turn down the speed.
Grit on abrasive too coarse Select a fi ner grit.
Surface quality not
perfect Incorrect abrasive grit Select a fi ner grit.
Drying times of the repair compound
not observed. Read the technical data sheets and manufac-
turer recommendations.
Suction power of PLANEX too strong Reduce the suction power of the PLANEX
Repair compound with a high percent-
age of fi ller, soft fi ller Select a fi ner grit, e.g. P180.
Machine set down on the surface
while running (groove formation) Place the machine in position and then switch
