WARNINGS

WARNINGS
  • DO NOT operate without a functional Ground Fault Circuit Interupter (GFCI).
  • DO NOT operate with a frayed, worn or damaged electrical cord.
  • DO NOT use to pick up flammable or combustible materials.
  • DO NOT run the pump without water in the water tank or without filter.
  • DO NOT use hot water.
  • DO NOT remove the float shutoff.
  • ALWAYS test chemicals for compatibility on surfaces to be cleaned.
  • ALWAYS winterize your Kaivac equipment between uses if it will be exposed to freezing temperatures.

GROUNDING INSTRUCTIONS

In short The KaiZen must be grounded and plugged into a properly grounded outlet to reduce the risk of electric shock. Do not cut the ground wire or modify the plug, and have a qualified electrician check the outlet if you are unsure.

THE KAIZEN 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 KaiZen 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 KaiZen. If it will not fit the outlet, have a properly grounded outlet installed by a qualified electrician.

SAFETY

Winterize Your Kaivac Equipment

In short This part explains how to winterize the machine if it will be exposed to freezing temperatures between uses. You pour windshield wiper fluid into the empty water tank and run the pump until the fluid comes through.‌‌​⁠⁠‍​‍⁠‌​‌‌⁠‍‌⁠​⁠‍​​​​​​⁠​​​​‌​⁠​​⁠‍​​‌​​​‍‍​‌​⁠‌​‍⁠​​⁠​‍‍

Your Kaivac machinery should be winterized between uses if it is to be exposed to freezing temperatures.‌‌​⁠⁠‍​‍⁠‌​‌‌⁠‍‌⁠​⁠‍​​​​​​⁠​​​​‌​⁠​​⁠‍​​‌​​​‍‍​‌​⁠‌​‍⁠​​⁠​‍‍

To winterize your machine:

  • Pour 1/2 gallon of windshield wiper fluid into the empty water tank.
  • Aim the spray gun into the water tank.
  • Run the pump and spray the gun until the fluid begins running through.

Chemical Use

In short Use only chemicals approved for the KaiZen and keep chemicals out of the water tank, except small amounts of KaiDri. Turn the chemical line off when not in use and keep the MSDS sheets on hand.
  • Only use chemicals approved for use with the KaiZen. 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 sheets 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.

Electrical

In short Connect the machine to a grounded outlet only and treat the power cord with care. Turn the unit off before unplugging, and pull on the plug, not the cord.
  • Connect to a properly grounded outlet only.
  • Do not pull the KaiZen by the cord or use the cord as a handle.
  • 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.

Prevention of Water Damage to Buildings

In short The KaiZen is for water resistant floor surfaces only. Never overflow the tanks, and stop using the machine if it leaks.
  • The KaiZen is to be used on water resistant building surfaces only. These include concrete, terrazzo, ceramic tile and quarry tile.
  • The KaiZen may be used for stripping on vinyl composite tile floors, but daily cleaning of resilient flooring using the KaiZen is not recommended.
  • Never overflow the water tank or the vacuum recovery tank.
  • Discontinue use if any leaks occur in the KaiZen.
CAUTION: Prior to cleaning, always inspect area to ensure that the surfaces to be cleaned are water-safe. In addition, check for poor construction, damaged walls and floors, missing or damaged tiles or grout, missing or insufficient caulk, and loose wall coverings. If problems are discovered, resolve them prior to cleaning in order to avoid any harm that may result from exposure to water or cleaning solution.

Hallway Cleaning

Hallway Cleaning

Method of Use

In short This method cleans a hallway in two passes: first apply cleaning solution to the floor with the spray gun in a serpentine pattern, then vacuum it off with the KaiAuto head, working back and forth along the hallway with a 2" overlap.‌‌​⁠⁠‍​‍⁠‌​‌‌⁠‍‌⁠​⁠‍​​​​​‌​⁠​​​‌​⁠​​⁠‍‌​⁠⁠⁠‍‌​‍‍⁠‍⁠​⁠⁠‍⁠⁠⁠​⁠

I. Apply Cleaning Solution

  1. Unwrap the spray gun and pressure hose. Leave 2 loops wrapped on the No-Touch Cleaning machine.
  2. Using the spray gun, apply a wide spray pattern of cleaning solution to the floor in a serpentine manner. (1 gallon covers approximately 800 feet.)
  3. For daily cleaning of waxed floors, it is recommended that you use a neutral (pH7) cleaning solution, such as KaiO™ from Kaivac.
Step 1, Apply Solution, Spray ON: an operator holding a spray gun, and a hallway diagram with a serpentine spray path running along the hallway beside an alcove that holds the cleaning machine
Step 1 Apply Solution. Spray ON.

II. Vac Off

  1. Connect the KaiAuto™ head to the Vac Wand and hose.
  2. Start vacuuming to the right of, and away from, the No-Touch Cleaning machine, heading along the wall.
  3. Proceed along the wall until you reach the limit of the hose length.
  4. Turn to the left 180° heading back toward the machine with a 2" overlap of the previous pass.
  5. Swerve KaiAuto towards the wall just as you pass the No-Touch Cleaning Machine (now vacuuming the wall on the left side of the machine) and continue down the hall.
  6. At the end of the hose make a 180° right turn heading back towards the unit with a 2" overlap of the previous pass.
  7. Continue this method until you reach the far wall away from the cleaning machine.

MACHINE MAINTENANCE

MACHINE MAINTENANCE

In short This page lists what to check on each part of the machine: the floor squeegee, spray gun, pressure hose, water filter, water tank, vacuum tank, leaks, electrical system and DVD system. Always make sure the machine is unplugged before lifting the electrical cover assembly.‌‌​⁠⁠‍​‍⁠‌​‌‌⁠‍‌⁠​⁠‍​​​​​‌⁠⁠​​​‌​⁠​​‍‌⁠⁠​‍‌‍⁠‍⁠‍⁠​‌‍⁠​⁠‍⁠‌‌⁠
CAUTION Always make sure machine is unplugged before lifting electrical cover assembly
ItemProcedure
Floor Squeegee
  • Check condition of rubber squeegee blades and wheels on the floor tool. Rough floor surfaces will cause the blades and wheels to wear out more quickly. Replace as necessary.
Spray Gun
  • Check spray pattern. If spray pattern will not pinpoint, clean orifice by removing it with an Allen wrench and flushing. Replace if not pinpointing.
  • If nozzle becomes difficult to move from high to low pressure lubricate nozzle with lithium grease.
Pressure Hose
  • Wipe clean after each use.
  • Check for cuts or frays in the hose jacket, particularly at the end of the fittings. Replace hose if cuts are found.
Water Filter
  • Check filter screens for debris and clean as needed. Be careful not to crush the end of the filter screen when replacing.
  • Check the clear filter bowl cover to be sure it is tight.
  • Check for leaks around filter and filter connections.
Water Tank
  • Check condition of filter in water tank. Clean as needed.
  • Empty the water tank to prevent mildew and bacteria growth. Empty tank by dipping the vacuum hose onto the water tank and transferring the water to the vacuum tank.
Vacuum Tank
  • Empty and flush vacuum tank.
  • Clean and disinfect.
  • Check the float shutoff screen to be sure it is not plugged up. A plugged filter screen restricts airflow and results in reduced suction.
Leaks
  • Be alert for leaks around hoses, fittings, spray wand, tanks or elsewhere. Discontinue use until leaks are repaired.
Electrical System
  • The ground fault circuit interrupter (GFCI) must be tested before each use.
  • Electric cords must be inspected for tears or cuts in the insulation.
DVD System
  • Make sure DVD player is dry and free of any debris placed on top or inside of storage compartment.
