Electrical Shock Or Personal Injury
Hazard
Disconnect electrical supply before
servicing or cleaning the unit.
Failure to do so could result in elec-
trical shock or personal injury from
cleaner suddenly starting.
Always follow all safety precautions when
cleaning and servicing the vacuum cleaner.
If the cleaner does not seem to have ade-
quate suction, first check if the dust bin is
full or if a filter is clogged. See DUST BIN
CLEANING and FILTER CLEANING /
CHANGING.
If the dust bin and filter areas are free of
clogs, check the hose area. Remove the
suction inlet by depressing the two tabs that
secure it to the back of the vacuum and
check for clogging in this area.
Hose
Tabs
Inlet
Motor Holder
Replace the suction inlet and remove the
other end of the hose from the tool holder.
Plug in the vacuum and turn it on. While
running the vacuum cleaner, stretch the
hose in and out to remove the clog.
Turn the unit off and unplug the unit.
If the clog still exists, pull the short hose out
of the tool holder and inspect the short
hose.
Remove any visible clogs.
NOTE: Do not block motor protector.
This vacuum has a motor protector by-pass
valve which automatically opens to provide
cooling air to the motor when a clog
prevents the normal flow of air. If the by-
pass valve opens to prevent motor
overheating and possible damage to the
vacuum, a change of sound will be noticed
as air rushes through the valve opening. If
this occurs, turn the vacuum off and unplug
the power cord from the outlet. Then check
for clogs as described under the CLOG
REMOVAL section.
The motor protector by-pass valve may
open when using attachments or when
cleaning new carpet, due to reduced air flow
caused by the attachments themselves or
by new carpet fuzz filling the dust bin
