    • Do not run vac unattended.
  • Do not vacuum, or use this Wet/Dry Vac near flammable liquids, gases, or explosive vapors like gasoline or other fuels, lighter fluids, cleaners, oil-based paints, natural gas,  hydrogen, or explosive dust like coal dust, magnesium dust, grain dust, or gun powder.

  • Do not vacuum anything that is burning or smoking, such as cigarettes, matches, or hot ashes.
  • Keep cord away from heated surfaces.
  • Do not expose to rain. Store indoors.
  • Do not unplug by pulling on the cord. To unplug, grasp the plug, not the cord.

  • If the appliance is not working as it should, has been dropped, damaged, left outdoors, or dropped into water, return it to a service center.
  • Do not pull or carry by cord, use cord as a handle, close a door on cord, or pull cord around sharp edges or corners.
  • Do not run Wet/Dry Vac over cord.
  • Do not handle the plug or the Wet/Dry Vac with wet hands.
  • To reduce the risk of health hazards from vapors or dust, do not vacuum toxic materials.
  • Do not use or store near hazardous materials.
  • Do not use this Wet/Dry Vac with a torn filter or without the filter installed except when vacuuming liquids as described in the operation section of this manual.
  • Do not allow it to be used as a toy. Close attention is necessary when used by or near children.

  • Use only as described in this manual. Use only the manufacturer’s recommended attachments.
  • This appliance is provided with double insulation. Use only identical replacement parts. See
    “DOUBLE INSULATION INSTRUCTIONS”.

DOUBLE INSULATION INSTRUCTIONS

This Wet/Dry Vac is double-insulated, eliminating the need for a separate grounding system. Use only identical replacement parts. Read the instructions for Servicing Double- Insulated Wet/Dry Vacs before servicing. Use this Wet/Dry Vac as described in this manual. Observe the following warnings that appear on the motor housing of your  Wet/Dry Vac.
DOUBLE INSULATED – GROUNDING NOT REQUIRED – WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT PARTS.

WARNING: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT EXPOSE YOURSELF TO RAIN.
STORE INDOORS.
CAUTION:
Do not vacuum drywall dust or fireplace soot or ash with a standard Wet/Dry filter. This is very fine dust that will not be captured by the filter and may cause damage to motor. When vacuuming fine dust use a fine dust filter (sold separately).

WARNING: SERVICING OF DOUBLE-INSULATED WET/DRY VACUUM WITH A DOUBLE- INSULATED WET/DRY VACUUM, TWO SYSTEMS OF  INSULATION ARE PROVIDED INSTEAD OF GROUNDING. NO GROUNDING MEANS IS PROVIDED ON A DOUBLE-INSULATED APPLIANCE, NOR SHOULD A MEANS FOR GROUNDING BE ADDED.
SERVICING A DOUBLE INSULATED WET/DRY VACUUM REQUIRES EXTREME CARE AND KNOWLEDGE OF THE SYSTEM, AND SHOULD BE DONE  ONLY BY QUALIFIED SERVICE PERSONNEL. REPLACEMENT PARTS FOR A DOUBLE-INSULATED WET/DRY VACUUM MUST BE IDENTICAL TO THE  PARTS THEY REPLACE. YOUR DOUBLE-INSULATED WET/DRY VAC IS MARKED WITH THE WORDS ‘DOUBLE INSULATED’ AND THE SYMBOL (SQUARE WITHIN A SQUARE) MAY ALSO BE MARKED ON THE APPLIANCE.

  • DO NOT use without filters in place.

CAUTION: TO REDUCE THE RISK OF INJURY FROM MOVING PARTS, UNPLUG BEFORE SERVICING.

POLARIZED PLUG
To reduce the risk of electrical shock, this appliance has a polarized plug (one blade wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper outlet.
Do not change the plug in any way. Double insulation eliminates the need for the three-wire grounded power cord and grounded power supply system.

IMPORTANT! When vacuuming large quantities of liquids, do not immerse the nozzle completely in the liquid; leave a gap at the tip of the nozzle opening to allow air inflow.  The machine is fitted with a float valve that stops the suction action when the collection tank reaches its maximum capacity. You will notice an increase in motor speed. When this happens, turn off the machine, disconnect from the power supply, and drain the liquid into a suitable receptacle or drain. After wet vacuuming, turn the machine off and remove the plug from the power supply. Empty the collection tank, and clean and dry the inside and outside before storage. REMEMBER! The foam wet filter must be removed after wet vacuuming, and a cartridge filter must be installed before dry vacuuming again.

MAINTENANCE

  1. Verify that the power cord is disconnected from the outlet. (fig.1)
  2. Disconnect the hose from the vacuum. (fig. 2)
  3. Undo the latches and remove the power head from the collection tank. (fig. 3)
  4. Clear all dirt or debris from the collection tank and hose. (fig. 4)

  6. Check the hose, attachments, and power cord to verify that they have not been damaged.
  7. Place power head on collection tank and secure latches.

IMPORTANT! Clean or change the cartridge filter regularly for best performance. ALWAYS USE A CARTRIDGE FILTER FOR DRY VACUUMING. If the machine is used without the cartridge filter, the motor will burn out and the warranty will be voided. Always keep spare filters on hand.
NOTICE! The filters included are made of high-quality materials designed to stop small dust particles. The cartridge filter should be used for dry pick-up only. A dry cartridge filter is necessary to pick up dust. If the cartridge filter is wet, it will clog quickly and be very difficult to clean. Handle the filter carefully when removing it for cleaning and replacing it. Check the filters for tears or small holes, a small hole can let dust pass through and out of the filter. Do not use a filter with holes or tears in it; replace it immediately.

WARNING! ALWAYS DISCONNECT THE PLUG FROM THE POWER OUTLET BEFORE REMOVING THE POWER HEAD FROM THE COLLECTION TANK.
