IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
- Connect to a properly grounded outlet. Do Not Remove Ground Pin
- Inspect Cord Before Using - Do Not Use If Cord Is Damaged
- Keep All Conections Dry And Off The Ground
- Do not Touch Plug With Wet Hands
- This Product Is 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.
- Do not close a door on the cord or pull the cord around sharp edges or corners.
- Do not run over the cord.
- Keep the cord away from heated surfaces.

- Turn off the unit before unplugging.
- Do not pull on the cord to unplug. Grasp the plug at the outlet and pull.
- Read Instruction Manual Before Using
Grounding Instructions
THE KAIVAC MUST BE GROUNDED. If it should malfunction or stop working, grounding provides a path of least resistance for the electrical current and reduces the risk of electrical shock. The KaiVac is equipped with a ground fault circuit interrupter (GFCI) to further reduce danger of electric shock. It must be maintained and tested regularly. An equipment grounding cord and plug is included with the unit. The plug must be inserted in an appropriate outlet that has been properly installed and grounded in accordance with all local codes and ordinances. Cutting off the ground wire or using a cord with an ungrounded plug will void the warranty on the unit, and Kaivac, Inc. will NOT accept responsibility for the unit.
Improper connection of the equipment grounding cord can result in the risk of electrical shock. Ask a qualified electrician or service person to check the outlet grounding if you are unsure. Do not modify the plug provided with the KaiVac. If it will not fit the outlet, have a properly grounded outlet installed by a qualified electrician.
IMPORTANT SAFETY INSTRUCTIONS

- To reduce the risk of injury, close supervision is necessary when a product is used near children.

Inspection
Carefully unpack and inspect your new KaiVac cleaning machine for shipping damage. Each unit is tested and thoroughly inspected before shipping. For instructions regarding any shipping damage, contact Kaivac Inc. immediately. All returns must have a Return Authorization Number (RAN), which is available by calling the Kaivac Inc. Technical Service Department.
Equipment Use
- Use the equipment for the purposes specified by the manufacturer.
- Do not remove the float shutoff.
- Do not run the pump dry. This will void the machine warranty.
- Do not run hot water through the pump. This will void the warranty.
- Always test chemicals for compatibilty on surfaces to be cleaned.
- Always be sure the water tank and water line filters are clear of debris.
- Do not use to pick up flammable or combustible materials.
- Replace any damaged cords before use.
- See the S-I-M-P-L-E operation section for proper use of equipment.
Chemical use
- Only use chemicals approved for use with the KaiVac. Use of non-Kaivac chemicals may cause machine damage and will reduce warranty periods. Turn chemical line off when not in use.
- Keep the appropriate chemical MSDS on hand at all times.
- Cleaning chemicals should not be put in the water tank (with the exception of KaiDri in small amounts). Chemicals in the water tank can harm operator and machine because:
- Chemicals in the water tank must pass through the pump, which may cause premature pump failure.
- Use of chemicals in the water tank voids the warranty.
- Chemicals in the water tank will be aerosolized and may harm the operator.
Training
- Proper training is required before using the KaiVac. Contact your authorized Kaivac Inc. distributor for training information.
- Instruction placards are attached to each KaiVac and should not be removed.
- These placards show proper cleaning procedures and safety precautions.
Prevention of Water Damage to Buildings
The KaiVac is to be used on water resistant building surfaces only. These include concrete, terrazzo, ceramic tile and quarry tile.
The KaiVac may be used for stripping on vinyl composite tile floors, but daily cleaning of resilient flooring using the KaiVac is not recommended.
Never overflow the water tank or the vacuum recovery tank.
Discontinue use if any leaks occur in the KaiVac.
Prepairing your Kaivac For Use
- 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 and selecting the proper metering tip. (See placards for metering tip information.)
- Check machine for all tools and supplies needed to complete task.
- If using a cleaning product that has high foaming use a foam inhibitor to cut down on foam. Pour 2 capfulls 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.

- Vac hose can now be wrapped onto machine. Leave vac motor running while wrapping to avoid water dripping from end of hose. To completely dry hose leave vac motor running for about 3 minutes.
- With Dump Hose opened to floor drain, spray inside of vac tank with clean water moving hose in a circular pattern to insure tank walls and float shutoff are rinsed.
