1.2 Safety Precautions: Corded Units Only
IMPORTANT SAFETY INSTRUCTIONS — SAVE THESE INSTRUCTIONS
READ ALL INSTRUCTIONS BEFORE USING (THIS APPLIANCE)
In short This section lists the safety precautions to follow when using the corded unit, including the extra warnings for the spray system. Read all of them before use, keep the cord and connections away from liquid and heat, and never use the unit without the float and the dust bag and/or filters in place.
When using an electrical appliance, basic precautions should always be followed, including the following:
WARNING: To reduce the risk of fire, electric shock, or injury:
- Turn off the unit before unplugging. Do not leave appliance when plugged in. Unplug from outlet when not in use and before servicing.
- Connect to a properly grounded outlet only. Do not remove ground pin. See Grounding Instructions below.
- DO NOT allow 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 manufacturer’s recommended attachments.
- Inspect cord prior to use. Do not use with damaged cord or plug. If 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 handle plug or appliance with wet hands.
- DO NOT pull or carry by cord, use cord as handle, close a door on cord, or pull cord around sharp edges or corners. Do not run appliance over cord. Keep cord away from heated surfaces.
- DO NOT unplug by pulling on cord. To unplug, grasp the plug, not the cord.
- DO NOT put any object into openings. Do not use with any opening blocked; keep free of dust, lint, hair, and anything that may reduce air flow.
- Keep hair, loose clothing, fingers, and all parts of body away from openings and moving parts. Turn off all controls before unplugging.
- Use extra care when cleaning on stairs.
- DO NOT use to pick up flammable or combustible liquids such as gasoline, or use in areas where they may be present.
- DO NOT pick up anything that is burning or smoking, such as cigarettes, matches or hot ashes.
- If using extension cord with appliance, make sure the connection is above the floor and away from exposure to liquid.
- Keep all connections dry and off the ground.
- To reduce the risk of injury, close supervision is necessary when a product is used near children.
- Stay alert - watch what you are doing.
- Keep operating area clear of all persons.
- The Kaivac shall be disconnected from mains during cleaning or maintenance and when replacing parts or converting the machine to another function.
- DO NOT overreach or stand on unstable support. Keep good footing and balance at all times.
- DO NOT operate without the float installed. If float is removed, reinstall by screwing back into place.
- Keep the cord away from heated surfaces.
- DO NOT use without dust bag and/or filters in place.
- This product comes with a grounded attachable extension cord. If damaged, replace with equivalent cord. This cord must be attached and mechanically secured using the provided cord connector to use the equipment.
- DO NOT operate the product when fatigued or under the influence of alcohol or drugs.
- Know how to stop the product and bleed pressures quickly. Be thoroughly familiar with the controls.
- Follow the maintenance instructions specified in the manual.
SPRAY SYSTEM WARNINGS (ONLY):
- DO NOT spray liquid from the Kaivac onto electrical outlets or any electrical devices.
- Risk of injection or injury to persons - DO NOT direct discharge stream at persons.
- INJECTION HAZARD: Equipment can cause serious injury if the spray permeates the skin. Do not point the gun at anyone or any part of the body. In case of permeation, seek medical aid immediately.
- THIS SYSTEM IS CAPABLE OF PRODUCING 500 PSI (3447 kPa). To avoid rupture and injury, do not operate this pump with components rated less than 500 PSI (3447 kPa) working pressure (including but not limited to spray guns, hose, and hose connections); and before servicing, cleaning or removal of any part, shut off power and relieve pressure.

1.2 Safety Precautions:Corded (Continued)
In short This page continues the safety rules for corded machines. It covers the built-in GFCI, the need to ground the machine and plug it into a properly grounded outlet, and the requirement to use the machine indoors only.
- High pressure cleaners shall not be used by children, persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge or untrained personnel. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.
- This product may also have been provided with a ground fault circuit interrupter built into the power cord. If replacement of the plug or cord is needed, use only identical replacement parts.
- Test the ground fault circuit interrupter (GFCI) before each use.
- Personal Protective Equipment (PPE): It is recommended to wear proper personal protective equipment as required by the chemical product label instructions used in conjunction with the appliance.
GROUND FAULT CIRCUIT INTERRUPTER PROTECTION (for spray systems only)
This machine was supplied with a ground-fault circuit-interrupter(GFCI) built into the plug of the power-supply cord. This device provides additional protection from the risk of electric shock. Should replacement of the plug or cord become necessary, use only identical replacement parts that include GFCI protection.
This appliance is for use on a nominal circuit and has a grounding attachment plug. Make sure that the appliance is connected to an outlet having the same configuration as the plug. No adapter should be used with this appliance.
GROUNDING INSTRUCTIONS
This product must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This product is equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local DOE and ordinances.
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 appliance – if it will not fit the outlet have a proper outlet installed by a qualified electrician.
FOR INDOOR USE ONLY
INTENDED FOR COMMERCIAL USE
WARNING — To Reduce the Risk of Electric Shock — Do not expose to rain. Store indoors.

2.3 Preparation For Use
In short This section lists the checks to make before cleaning: fill the machine with water, set up the cleaning solution and metering tip, and confirm tools and supplies are on hand. Check hoses and spray lines for damage, then plug in the machine and test the GFCI.
- Fill machine with clean, cool water.
- Prepare the cleaning solution you will be using by attaching the chemical feed line and cap to the top of your chemical bottle. Then select the proper metering tip. (See placard for metering tip information)
- Check machine for all tools and supplies needed to complete task. See Tool Arrangement in Section 2.2 of this manual.
- If using a cleaning product that foams, use a foam inhibitor to cut excess. Pour 2 capfuls of inhibitor in the Vac Hose with Vac running to coat inside of Hose.
- Check all hoses and spray lines for damage prior to use. If damage is found, do not continue until proper repairs are completed.
- Plug in machine and test GFCI (Ground Fault Circuit Interrupter) to ensure it is working properly. You are now ready.

4.5 Replacement (Monthly)
In short Monthly tasks keep the system performing at its best. Check the squeegee blades for wear, and replace the Vac Wand head every 6-8 weeks by unscrewing the cuff.
The following tasks should be performed monthly to keep your system operating at peak performance.
Check for worn squeegee blades. Worn blades cause streaking and loss of vacuum suction.
Unscrew cuff at end of Vac Wand, remove old head and replace with new every 6-8 weeks for optimal performance.
