1.5 Battery Information

Keep Batteries at Room Temperature: Store between 32 and 113 degrees F (00C to 450C). Avoid battery exposure to extreme temperatures. If shelving battery longer than (1) month, then deplete battery to 50% charge (two bars on the battery indicator).
Batteries Lose Capacity Over Time: Batteries naturally deteriorate over time whether being used or not. If battery use instructions are properly followed, batteries deteriorate at a rate of 10% run time per year.
Fully Discharge vs. Partial Discharge and the Effect on Battery Cycles: Unlike lead acid batteries typically used in auto scrubber, the Kaivac Battery is not damaged by fully discharging. The BMS (Battery Management System) has a cutoff voltage of 30V which protects the Battery from experi-encing full discharge. Running the Battery to full discharge will reduce the amount of charge cycles. The expected hours of use are approximately 600 hours. For example, if running to full discharge, you would expect 400 cycles. If you run to 80% discharge, then you would expect to get more cycles (500 cycles). With dual batteries make sure to alternate batteries per charge for full life capacity.
Extended Storage: It is recommended to discharge to 50% capacity (two bars on the battery indicator) and store in a cool location (between 320F to 1130F or 00C to 450C). To avoid battery impact, store battery laying down on its side on lowest shelf, and secured. If battery is dropped or experi-ences an impact, discontinue use and replace. Using a damaged battery can result in damage to the unit.
Battery Gauge: The Kaivac Batteries come with a built-in Battery Gauge or “Fuel Gauge” which shows the approximate run time for the current charge remaining.
Disposal: Rechargeable batteries eventually wear out. When your Kaivac Battery run time is less than 55% (i.e. 50 minutes for non-quick change and 33 minutes for Quick Change batteries), then we recommend replacing your battery.

DO NOT DISCARD BATTERY INTO TRASH! Doing so can lead to a fire. It is important to recycle your old batteries at your local recycling facility or by calling 1-800-USA-CLEAN (1-800-872-2532) and selecting Option 3.

1.6 Grounding Information

Grounding: Corded Units

GROUND FAULT CIRCUIT INTERRUPTER PROTECTION (for spray systems only)
This machine was supplied with a ground-fault circuit-interrupter(GFCI) built into the plug of the power-supply cord. This device provides additional protection from the risk of electric shock. Should replacement of the plug or cord become necessary, use only identical replacement parts that include GFCI protection.
This appliance is for use on a nominal circuit and has a grounding attachment plug. Make sure that the appliance is connected to an outlet having the same configuration as the plug. No adapter should be used with this appliance.

GROUNDING INSTRUCTIONS
This product must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This product is equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local DOE and ordinances.

Improper connection of the equipment-grounding conductor can result in a risk of electric shock. Check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the appliance – if it will not fit the outlet have a proper outlet installed by a qualified electrician.

This product comes with a grounded attachable extension cord. If damaged, replace with Kaivac® (OEM) cord, or if necessary an equivalent cord rated 120V, 15 amps, 3-wire, 14 GA. This cord must be attached and mechanically secured using the provided cord connector to use the equipment.

Grounding: Battery Units

GROUNDING INSTRUCTIONS
The charger must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This appliance is equipped with a cord having equipment grounding conductor and grounding plug. The plug must be inserted into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Improper connection of the equipment-grounding conductor can result in a risk of electric shock. Check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the appliance – if it will not fit the outlet; have a proper outlet installed by a qualified electrician.
This appliance is for use on a nominal circuit and has a grounding attachment plug. Make sure that the appliance is connected to an outlet having the same configuration as the plug. No adapter should be used with this appliance.

Make sure your extension cord is in good condition and is the correct size for your appliance. Table 1 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord. An undersized extension cord will cause a drop in line voltage resulting in loss of power and overheating.
Use only three-wire outdoor extension cords that have three-prong grounding receptacles that accept the appliance’s plug.

 To reduce the risk of personal injury due to a loose electrical connection between the appliance’s plug and extension cord, firmly and fully attach the appliance plug to the extension cord. Periodically check the connection while operating to ensure it is fully attached. Do not use an extension cord that provides a loose connection. A loose connection may result in overheating, fire, and increases the risk of a burning.

To reduce the risk of disconnection of the appliance cord from the extension cord during operations:
• Make a knot as shown in Figure 1 below:
