For longer service life and safe use of your vacuum, we recommend the following guidelines: Your cleaner is designed to pick up dirt and dust particles and water. Avoid picking up hard or sharp objects with your cleaner to avoid bag breakage, clogging or possible motor damage.
Remove the plug from the socket before performing maintenance. Before using the machine make sure that the frequency and voltage shown on the rating plate correspond with the mains voltage.
CARE OF YOUR VACUUM CLEANER
Treat your vacuum cleaner as you would any other high grade precision made product. Dropping, unreasonable bumping across thresholds and other misuses may result in a damaged unit which will not be covered under warranty. When not in use the power cord should be wrapped around the molded-in cord wrap for storage. After each use, wipe the vacuum body, accessories and power cord with a slightly damp cloth.
GROUNDING INSTRUCTIONS
DANGER: IMPROPER USE OF THE GROUNDING PLUS CAN RESULT IN A RISK OF ELECTRIC SHOCK.
Electrical equipment must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance for electrical current to reduce the risk of electric shock. The vacuum is equipped with a cord containing a grounding conductor and grounding plug. The plug must be inserted into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.
If repair or replacement of the cord or plug is necessary. DO NOT connect the grounded wire to a flat bed terminal. The wire with insulation having an outer surface that is green with or without yellow stripes is the grounding wire.
GROUNDING METHODS
This electric equipment is for use on a normal 120 volt circuit. It has a grounded plug that looks like a the plug illustrated in (Fig A). A temporary adapter that looks like the adapter illustrated in (Fig B & C) may be used to connect this plug into a 2-pole receptacle as shown in (Fig B) if a properly grounded outlet is not available.
The temporary adapter should be used only until a properly grounded outlet (Fig A) can be installed by a qualified electrician. The green color rigid ear lug or the like extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box cover. Whenever the adapter is used, it must be held in place by a metal screw.
WARNING:
Improper connection of the equipment grounding conductor can result in a risk of electric shock. Check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded. DO
NOT modify the plug provided with the equipment. If it will not fit into the outlet, have a proper outlet installed by a qualified electrician.
Note: In Canada, the use of a temporary adapter is not permitted by the Canadian Electrical Code.

DRY USE
Make sure that the plug is disconnected from the source of electricity. Remove the top of the vacuum and ensure that the cloth filter dust bag is properly installed. This vacuum comes equipped with a cloth dust bag filter.
The dust bag filter should always be used when picking up dry material and can be easily disposed of without creating a mess. The dust bag should be used for dry cleaning only and must be removed when being used for wet use.
The dry dust bag is not reusable or washable. Make sure the dust bag is secure inside the tank prior to use.
Check bag frequently, and remove and dispose of debris when bag is about 4/5 full. Overfilling the bag may make it difficult to remove and increases the risk of the bag breaking and spilling the contents.
Put the top of the vacuum back into its original position and secure it onto the tank snapping down the latches on both sides. Insert the flexible hose into the tank of the vacuum, assemble the steel wand and connect to the hose. Connect the plug to the electricity source. Push the switch to the on position and start cleaning.
This vacuum is equipped with multiple tools to help with various applications. Scalloped bristle floor brush for carpets, tile and other flooring. Dust brush for hard to reach places like base boards and window sills, inside cars, furniture, etc.
At the end of your work, turn off the machine by pushing the switch to the off position. Disconnect the plug from the source of electricity. Remove the cloth dust bag and dispose of debris. Wipe down machine with damp cloth.
WET USE
Make sure that the tank does NOT contain dust and disconnect the plug from the source of electricity. Remove
the Dust filter bag. Replace the top back onto the vacuum ensuring the two latches are securely fastened.
Connect the plug to the source of electricity. Turn the machine on by pushing the switch to the on position. The squeegee tool included with the vacuum is ideal for wet clean up. At the end of your work, turn off the machine by pushing the switch to the off position. Disconnect the plug from the source of electricity. Dispose of all liquid from tank by unclipping the disposal hose. Simply remove the end cap from the hose and slowly lower the drain hose to release the contents into a suitable drain. Replace end cap and clip hose back to machine. Wipe down machine with damp cloth.
ATTENTION! This vacuum is equipped with a ball float shut off. When the maximum level of fluid has been reached, there will be a significant change in sound and airflow through the hose will decrease. This feature provides protection to the vacuum motor by shutting down airflow before motor damage occurs.
