AUTOMATIC SUCTION SHUT OFF

The vacuum is equipped with an automatic suction shut-off that operates when picking up liquids. As the
level of the liquid rises in the tank, an internal float rises until it seats itself against a seal at the intake of the
motor, shutting off suction. When this happens, the motor will develop a higher than normal pitch noise and
the suction is drastically reduced. If this occurs, turn unit off immediately. Failure to turn unit off after float
rises and shuts off suction will result in extensive damage to the motor. To continue use, empty the liquid
waste from the tank as outlined in the previous section.
NOTE : IF ACCIDENTALLY TIPPED OVER, THE VACUUM COULD LOSE SUCTION, IF THIS OCCURS, TURN UNIT
OFF AND PLACE VAC IN UPRIGHT POSITION. THIS WILL ALLOW THE FLOAT TO RETURN TO ITS NORMAL
POSITION AND YOU WILL BE ABLE TO CONTINUE OPERATION.
No lubrication is necessary as the motor is equipped with lifetime lubricated bearings.
1. Before storing your vacuum the tank should be emptied and cleaned.
2. The power cord can be wrapped around the cord wraps provided on back of the tank cover.
3. The hose may be stored in the hose holder. To do this place one end of the hose
between the hose holder posts and the tank cover. Wrap the hose around the tank
cover keeping the hose tucked between the posts and the cover.
4. The accessories may be stored in the tool storage, that came with
your vacuum. Some models come with a rear tool rack or basket.
Other models come with slots in the hose holder and in the back of
the tank cover. The vacuum should be stored indoors.
