BY-PASS VALVE
This vacuum cleaner has a By-Pass Valve
which prevents motor overheating and
damage. The valve opens to provide
cooling air when a clog prevents normal
air flow to the vacuum cleaner suction
motor. You will notice a change of sound
as air rushes through the valve opening.
To correct the problem: remove any clogs,
check and replace filters if needed, check
and empty dust cup if needed.
NOTE
: The By-Pass Valve may open
when using attachments or when cleaning
new carpet due to reduced airflow or air
path is blocked, caused by the attachments
themselves or by new carpet lint filling the
dust cup quickly.
PERFORMANCE/SAFETY FEATURES
SUCTION CONTROL
To assist with push/pull force of the
vacuum on surfaces like thick carpet, the
suction control valve can be opened to
help reduce suction. Note that for best
cleaning results, the suction control valve
must be fully closed.
· Slide to right to open the suction control
and decrease suction. Opening control
decreases suction for draperies and
lightweight rugs.
· Slide to left to close the suction control
and increase suction. Closing control
increases suction for upholstery and
carpets.
