Loss of pick-up from the low profile contact head
Carry out these checks if the customer reports low suction or loss of pick-up from the low profile contact head.
For turbine head variants carry out the ‘Turbine head brush bar not operating’ checks on p.21 before continuing with checks from
this section.
Switch off and unplug the machine before carrying out these checks:
Remove hose from the inlet and switch
machine ON.
Test suction from the inlet. If suction is
weak continue with checks, if strong
go to step 10. Switch machine OFF.
Remove the cyclone and bin assembly.
Check bin and cyclone for blockages
or obstructions and make sure the
shroud is clear of debris.
Check bin entry and cyclone exhaust
for blockages.
Check duct for blockages in the area
shown.
Open the pre-filter cover by turning
the release catch. (The machine
can be placed on its side for easier
access.)
Remove the pre-filter. Ask the customer
to wash if necessary (when the call has
ended). Ensure pre-filter is completely
dry before refitting.
Ask the customer to refit the cyclone
and bin assembly.
