Introduction

Introduction

Inspection

In short This section covers what to do when a new machine arrives: unpack it and check for shipping damage. Contact Kaivac, Inc. right away about any damage, and get a Return Authorization Number before returning anything.‌‌​⁠‌‌⁠‍‍‌‌‌⁠‌⁠‍⁠‌‍​​​​​​​‌‌​​​‌​⁠​​‍‌‌​‍‌‍​​⁠⁠‌‌‌⁠‌‌‌‍‌‌​‍​

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. Customer Service Department.‌‌​⁠‌‌⁠‍‍‌‌‌⁠‌⁠‍⁠‌‍​​​​​​​‌‌​​​‌​⁠​​‍‌‌​‍‌‍​​⁠⁠‌‌‌⁠‌‌‌‍‌‌​‍​

Warnings

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.
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

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.

Safety Precautions

Safety Precautions

In short This section lists the safety rules for using the KaiVac: get proper training, use the equipment only as specified, use a GFCI, wear personal protection, and avoid pump damage. It also describes how to winterize the machine when it will be exposed to freezing temperatures.‌‌​⁠‌‌⁠‍‍‌‌‌⁠‌⁠‍⁠‌‍​​​​​​​‌‍​​​‌​⁠​​‌​‌⁠‍‍‌⁠‍‍‌⁠​​⁠‌‍‌‌‍⁠‍‍⁠

Equipment Warning

  • Read all instructions to ensure safe operation of the KaiVac.

Training

  • Proper training is required before using the KaiVac. Contact your authorized Kaivac 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.

Equipment Use

  • Use the equipment for the purposes specified by the manufacturer. Do not use the equipment for any other purpose.
  • See the S-I-M-P-L-E operation section for proper use of equipment.

Spray Gun

  • Never point the spray gun at people.

Prevention of Electrocution

  • Use the ground fault circuit interrupter (GFCI) with the KaiVac at all times.
  • Test the GFCI before each use.
  • Do not spray liquid from the KaiVac onto electrical outlets or on any electrical devices.

Personal Protection

  • Wear gloves, eye protection and ear protection when operating the KaiVac.

Machine Integrity

  • Do not run the pump dry. This will void the machine warranty.

SAFETY

Chemical use

In short This page covers safe use of chemicals, the power cord and water around buildings. Use only approved chemicals, keep them out of the water tank, plug into a grounded outlet only, and check that surfaces are water-safe before cleaning.‌‌​⁠‌‌⁠‍‍‌‌‌⁠‌⁠‍⁠‌‍​​​​​​​‌⁠​​​‌​⁠​​‌‌‌​⁠‍‌‍‍‌‌‍‍‍​⁠⁠​‍‍​⁠‌‍
  • 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.

Electrical

  • Connect to a properly grounded outlet only.
  • Do not pull the KaiVac 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

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.

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.

Machine Maintenance

Machine Maintenance

In short This section lists what to check on each part of the machine: floor squeegee, spray gun, pressure hose, water tank, vacuum tank, leaks and the electrical system. The machine must be unplugged before the electric cover assembly is lifted.‌‌​⁠‌‌⁠‍‍‌‌‌⁠‌⁠‍⁠‌‍​​​​​​​‍⁠​​​‌​⁠​​‌‌​⁠​⁠‌‌‍​⁠‌‍​‌‌‍‌‌‍⁠‍‌⁠
CAUTION Always make sure machine is unplugged before lifting electric 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 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.
