Remedy
Clean the filter element regularly:
–
Use the mobile dust extractor's dedusting
function (see the operating manual for the
mobile dust extractor).
–
Manually clean the filter element (dust ex
traction).
–
Check the filter element for damage and
clogging. Use a new filter element regularly.
The holes punched in the disposal bag must be
inside the container.
Only work with the disposal bag.
Adjust the suction power to a higher setting.
Remove the blockage and straighten the hose.
Replace the disposal bag.
Switch off the power tool and allow it to cool
down. Switch on again and allow it to continue
cooling down in no-load mode. Then:
–
Reduce the suction power until the cause has
been rectified.
–
Apply less pressure.
–
Switch it off and clean the housing openings.
Switch on the power tool before placing it on the
surface.
Interruption to the power supply, e.g. due to
power failure or pulling out the mains plug.
Switch the power tool off and on again.
Check whether the bayonet fitting on the plug-it
mains power cable is completely closed and
locked.
Apply less pressure on the power tool, remove
the backing pad blockage or reduce the suction
power.
