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.

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. Unplug the machine before lifting the electric cover assembly, and stop using the machine if there are leaks.‌‌​⁠‌‌⁠‍‍‌‍‍‌‍‍⁠​‍⁠‍​​​​​​‍‍​​​‌​⁠​​⁠⁠​⁠​‌⁠‌​‌⁠‌‍‍⁠‍‌‍‍⁠⁠‌​‌
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.
