Thermal Cut-Off - Electrolux Z4700 Series Owner's Manual

How to Check and
Clear Hose Blockages
Low suction or poor pick-up may be due to a
blockage in the vacuum cleaner.
Step 1: Remove hose from hose retainer on the
base and check suction at end of hose. If
little or no suction, check dust cup. Empty
if needed. If no improvement, proceed to
step 2.
CAUTION: Turn off the switch and unplug
the electrical cord before
clearing hose.
Step 2: Remove electrical cord from cord hooks.
Disconnect the clear tube by unscrewing
the 2 screws, then lift away from cleaner.
Check for any obstructions that may be
in the tube or hose. Obstructions may be
removed by using a blunt instrument to
clear the tube or hose. Flexing the hose
may help loosen the blockage. After
clearing blockage, reverse above steps to
reassemble unit. (FIG. 21)
