1.3 SAFETY PRECAUTIONS

In short This section lists the safety rules for using the Kaivac, mainly about electrical shock, grounding and general safe operation. Use a properly grounded outlet, inspect the cord and test the GFCI before each use, and wear the protective equipment required by the chemical label.‌‌​⁠‌​​​‌​⁠​⁠‌‍‌‌⁠​‌​​​​​​‌‍​​​‌​⁠​​⁠‌‍​​⁠​​​‍⁠​‌‍‌‍‍⁠​‌‍​‍‍

IMPORTANT SAFETY INSTRUCTIONS—SAVE THESE INSTRUCTIONS‌‌​⁠‌​​​‌​⁠​⁠‌‍‌‌⁠​‌​​​​​​‌‍​​​‌​⁠​​⁠‌‍​​⁠​​​‍⁠​‌‍‌‍‍⁠​‌‍​‍‍

CAUTION: To reduce the risk of injury, read operating instructions carefully before using.
WARNING: Risk of injection or injury to persons – do not direct discharge stream at persons.
WARNING RISK OF ELECTROCUTION:
  • Connect to a properly grounded outlet. Do not remove ground pin.
  • Inspect cord before using – do not use if cord is damaged.
  • Keep all connections 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.
  • Keep the cord away from heated surfaces.
  • Do not spray liquid from the Kaivac onto electrical outlets or on any electrical devices.
  • Turn off the unit before unplugging.
  • Do not pull on the cord to unplug. Grasp the plug at the outlet and pull.

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 and risk of electric shock. It must be maintained and tested regularly. An equipment grounding cord and plug is included with the unit. Cutting off the ground wire or using a cord with an ungrounded plug will void the warranty on the Kaivac.

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 into the outlet, have a properly grounded outlet installed by a qualified electrician.

WARNING: When using this product, basic precautions should always be followed, including the following:
  • Read all the instructions before using the product.
  • To reduce the risk of injury, close supervision is necessary when a product is used near children.
  • Know how to stop the product and bleed pressures quickly. Be thoroughly familiar with the controls.
  • Stay alert – watch what you are doing.
  • Do not operate the product when fatigued or under the influence of alcohol or drugs.
  • Keep operating area clear of all persons.
  • Do not overreach or stand on unstable support. Keep good footing and balance at all times.

3.0 MAINTENANCE

3.1 MACHINE MAINTENANCE

In short This section is a checklist of what to inspect, clean or replace on each part of the machine, such as the floor tool, spray gun, hoses, tanks, electrical system and HEPA filter. Always unplug the machine before lifting the electric cover assembly.‌‌​⁠‌​​​‌​⁠​⁠‌‍‌‌⁠​‌​​​​​​‍⁠​​​‌​⁠​​‍‌‌⁠‍‌​‌​‌⁠​‌​‍⁠‍‌​‍‌‌‌‍
CAUTION Always make sure machine is unplugged before lifting electric cover assembly
ItemProcedure
Floor Squeegee
  • Check condition of 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 needed.
  • 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 into 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 cord must be inspected for tears or cuts in the insulation.
Vacuum Wand
  • Use a wire brush or coarse brush with acid cleaner or other to remove residue from threads on the coupling and coupling nut. Apply grease when done.
HEPA Filter
  • Replace every 3-6 months depending on use

3.3 PUMP & ELECTRICAL DIAGRAM

In short This section shows the pump diagram and the wiring diagram for the Kaivac 2100 series. Use them to see how the chemical, water and pump components connect and how the electrical circuit is wired.‌‌​⁠‌​​​‌​⁠​⁠‌‍‌‌⁠​‌​​​​​​⁠⁠​​​‌​⁠​​‌​⁠​⁠​⁠‍‍‌‌‍‌‌‌⁠‌‌‍‌⁠‍⁠‌
Pump diagram for the Kaivac 2100 series. Chemical bottles A and B with draw tubes, chemical caps, chemical cap check valves and chemical metering tips feed the chemical valve. The chemical valve leads to the chemical injector with check valve. The water tank with filter connects to the pump and unloader, with an unloader check valve. The pulse hose and pressure hose lead to the pressure hose mini ball valve, spray gun and spray nozzle. The pump and unloader are in the black box compartment, outlined by a dashed line. A note says chemical B only applies to dual chemical configurations.
