IMPORTANT SAFETY INSTRUCTIONS

Safety is a combination of using common sense, staying alert, and knowing how your Wet/Dry Vacuum Cleaner (“Vac”) works.
Safety Signal Words
DANGER: Indicates a hazardous situation that, if not avoided, will result in death or serious injury.
WARNING: Indicates a hazardous situation that, if not avoided, could result in death or serious injury.
CAUTION: Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury or property damage. When using your Vac, always follow basic safety precautions including the following:
WARNING:
– To reduce the risk of fire, electric shock, or injury:

Read and understand this manual and all labels on the wet/Dry Vac before operating.
Use only as described in this manual.
Do not leave Vac running while unattended – you may fail to notice important signs indicating abnormal operation such as loss of suction, debris/liquid exiting exhaust, or abnormal motor noises. Immediately stop using Vac if you notice these signs.
Do not leave Vac when plugged in. Unplug from outlet when not in use and before servicing.
Sparks inside the motor can ignite flammable vapors or dust. To reduce the risk of fire or explosion, do not use near combustible liquids, gases, or dust, such as gasoline or other fuels, lighter fluid, cleaners, oil-based paints, natural gas, coal dust, magnesium dust, grain dust, aluminum dust, or gun powder.
Do not vacuum anything that is burning or smoking, such as cigarettes, matches, or hot ashes.
To avoid the risk of self-ignition of drum debris, empty the drum after each use. Combustible materials, such as rags or sawdust containing stain or urethane, can be sources of such overheating.
Do not vacuum drywall dust, cold fireplace ash, or other fine dust with a standard filter. These may pass through the filter and be exhausted back into the air. Use a fine dust filter instead.
To reduce the risk of inhaling toxic vapors, do notvacuum or use near toxic or hazardous materials.
To reduce the risk of electric shock, do not expose to rain or allow liquid to enter the motor compartment. Store indoors.
This Wet/Dry Vac is not intended for use by persons(including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
Do not allow to be used as a toy. Close attention is necessary when used by or near children.
Do not use with a torn filter or without the filter installed except when vacuuming liquids as described in this manual. Dry debris ingested by the impeller may damage the motor or be exhausted into the air.
Turn off Vac before unplugging.
To reduce the risk of injury from accidental starting, unplug the power cord before changing or cleaning the filter.
Do not unplug by pulling on the cord. To unplug, grasp the plug, not the cord.
Do not use with a damaged cord, plug or other parts. If your Vac is not working as it should, has missing parts, has been dropped, damaged, left outdoors, or dropped
into the water, call customer service.
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 Vac over cord. Keep cord away from heated surfaces.
Do not handle plug, switch, or the Vac with wet hands.
Use only extension cords that are rated for outdoor use. Extension cords in poor condition or too small in wire size can pose fire and shock hazards. To reduce the risk of these hazards, be sure the cord is in good condition and that liquid does not contact the connection. Do not use an extension cord with conductors smaller than 1,3 mm2
(16 AUG).
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.
Do not put any object into ventilation openings. Do not vacuum with any ventilation openings blocked; keep free of dust, lint, hair or anything that may reduce air flow.
Keep hair, loose clothing, fingers, and all parts of the body away from openings and moving parts.
To reduce the risk of falls, use extra care when cleaning on stairs.
To reduce the risk of back injury or falls, do not lift a Vac that is heavy with liquid or debris. Partially empty by scooping debris or draining liquid.
To reduce the risk of personal injury or damage to Vac, use only RIDGID recommended accessories.
When using as a blower:
– Direct air discharge only at the work area.
– Do not direct air at bystanders.
– Keep children away when blowing.
– Do not use the blower for any job except blowing dirt and debris.
– Do not use as a sprayer.
To reduce the risk of eye injury, wear safety eyewear. The operation of any utility Vac or blower can result in foreign objects being blown into the eyes, which can result in severe eye damage.
To reduce the risk of being struck by, or pulled down by, a rolling Vac, block the casters when used on any uneven or sloped surface.

CAUTION:

To reduce the risk of hearing damage, wear ear protectors when used for extended hours or in a noisy area.
For dusty operations, wear a dust mask.
Static shocks are common when the relative humidity of the air is low. Vacuuming fine debris with your Vac can deposit static charge on the hose or Vac. To reduce the frequency of static shocks in your home or when using this Vac, add moisture to the air with a humidifier.

Observe the following warnings that appear on the motor housing of your Vac:
DOUBLE INSULATED – GROUNDING NOT REQUIRED. WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT PARTS.

**WARNING:**
To reduce the risk of electric shock – do not expose to rain – store indoors.

**WARNING:**

For your own safety, read and understand the owner’s manual.
Do not run unattended.
Do not pick up hot ashes, coals, flammable, combustible / self-igniting, toxic, or other hazardous materials.

OPERATION

**WARNING:** To reduce the risk of fire, explosion, or damage to Vac:

Do not leave Vac running while unattended – you may fail to notice important signs indicating abnormally operation such as loss of suction, debris/liquid exiting the exhaust, or abnormal motor noises. Immediately stop using Vac if you notice these signs.
Do not leave Vac plugged in when not in use.
Do not continue running when the float has cut off suction.
Sparks inside the motor can ignite airborne flammables.
Do not operate Vac near flammable liquids or in areas with flammable gases, vapors, or explosive/airborne dust. Flammable liquids, gases, and vapors include lighter fluid, solvent-type cleaners, oil-based paints, gasoline, alcohol, and aerosol sprays. Explosive dust include coal, magnesium, aluminum, grain, and gun powder.
Do not vacuum up explosive dust, flammable liquids, or hot ashes.
Do not leave sawdust or rags with stain or polyurethane residue inside Vac. Empty drum after picking up these potentially self-healing materials.

WARNING: To reduce the risk of electric shock or injury:

Do not expose to rain or allow liquid to enter the motor compartment. Store indoors.
Do not handle plug, switch, or Vac with wet hands.
Unplug Vac before servicing. If your Vac is not working as it should, has missing parts, has been dropped, damaged, left outdoors, or dropped into water, return it to an authorized service center or call customer service.

CAUTION: To reduce the risk of hearing damage, wear ear protectors when using the Vac/Blower for an extended time or in a noisy area.
POLARIZED PLUG / ON-OFF SWITCH (Fig. 7)
To reduce the risk of electric shock, this Vac has a Polarized Plug (one blade is 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.
With Power Cord plugged in, turn the Vac “ON” by pressing in on the “I” (top) on the Power Switch. To turn “OFF”, press the “O” (bottom) on the Power Switch. The symbols used on the Switch Actuator are international “ON & OFF” symbols.
VACUUMING DRY MATERIALS

The Filter must always be correctly installed to avoid leaks and possible Vac damage.
To maintain peak performance when vacuuming fine dust, clean the Dust Drum and Filter regularly.
NOTE: Do not use a wet Filter when picking up dry material. The Filter will quickly clog and be difficult to clean.
If the Filter is wet, you must allow it to dry completely or replace it with a dry Filter before using the Vac to pick up dry material.

VACUUMING LIQUIDS

Vacuuming up small amounts of liquid (less than 2” (5 cm) collected in Dust Drum) does not require Filter removal.
When larger amounts of liquid are to be picked up, remove all dry use only Paper Filter(s) and replace with a RIDGID wet application Foam Filter. Do Not remove the Filter Cage or Float. The Foam Filter is specifically designed for high volume liquid pick up. If the paper Filter is used and becomes saturated, you may see “mist” coming from the Blowing Port.
When the Dust Drum is “full” the Float will rise and cut off airflow. The motor sound will rise in pitch and its speed will increase indicating the Dust Drum is “full”. Turn OFF the Vac and unplug the power cord before emptying the Dust Drum.
Following the use of Vac for wet pick up, allow Filter to dry completely to avoid mildew and Filter damage. IMPORTANT: To reduce the risk of damage to the Vac, do not run Motor with Float in the raised position.

WARNING:
!Do not operate without a filter cage and float, as they prevent liquid from entering the impeller and damaging the motor.
EMPTYING THE DUST DRUM (Fig. 8)
WARNING:
To reduce the risk of injury from accidental starting, unplug the power cord before emptying the drum.

Unplug Power Cord from the power source.
The Vac comes equipped with a Drain for easy emptying of liquids. Position the Vac near a suitable drain or receptacle and remove the Drain Cap (C).
To Remove Powerhead Assembly: Push in on the Flexible Locking Tabs, disengaging them from the Powerhead Assembly Latch Lock Holes. Pull up on the Powerhead Assembly and set aside.
Empty Dust Drum (B) into a proper waste disposal container.
The Dust Drum (B) should be emptied and cleaned before storing your Vac.

WARNING:
To reduce the risk of back injury or falls, do not lift a Vac heavy with liquid or debris. Scoop or drain enough contents out to make the Vac light enough to lift comfortably.

BLOWING FEATURE (Fig. 9)
Your Vac features a Blowing Port. It can blow sawdust and other debris. Follow the steps below to use your Vac as a Blower.

CLEANING A DRY FILTER

Some removal of dry debris can be accomplished without removing the Filter from the Vac. Slap your hand on top of the Lid while the Vac is turned OFF.
For best cleaning results due to accumulated dust, clean the Filter outdoors in an open area.
After Filter removal from Vac, remove the dry debris by gently tapping Filter against the inside wall of your Dust Drum. The debris will loosen and fall.
For thorough cleaning of Dry Filter with fine dust (no debris), run water through Filter as described under “Cleaning A Wet Filter”.

CLEANING A WET FILTER
After the Filter is removed, run water through the Filter from a hose or spigot. Take care that water pressure from the hose is not strong enough to damage the Filter. IMPORTANT: After cleaning, check the Filter for tears or small holes. Do not use a Filter with holes or tears in it. Even a small hole can allow dust to come out of your Vac. Replace it immediately. Allow the Filter to dry completely before reinstalling and storing the Vac or picking up dry debris.
