Shipping the DEWALT FLEXVOLT™ Battery 

The DEWALT FLEXVOLT™ battery has two modes: Use and Shipping

Use Mode: When the FLEXVOLT™ battery stands alone or is in a DEWALT 20V Max* product, it will operate as a 20V Max* battery. When the FLEXVOLT™ battery is in a 60V Max* or a 120V Max* (two 60V Max* batteries) product, it will operate as a 60V Max* battery.

Shipping Mode: When the cap is attached to the FLEXVOLT™ battery, the battery is in Shipping Mode. Strings of cells are electrically disconnected within the pack resulting in three batteries with a lower Watt hour (Wh) rating as compared to one battery with a higherWatt hour rating. This increased quantity of three batteries with the lower Watt hour rating can exempt the pack from certain shipping regulations that are imposed upon the higher Watt hour batteries. The battery label indicates two Watt hour ratings (see example). Depending on how the battery is shipped, the appropriate Watt hour rating must be used to determine the applicable shipping requirements. If utilizing the shipping cap, the pack will be considered 3 batteries at the Watt hour rating indicated for “Shipping”. If shipping without the cap or in a tool, the pack will be considered one battery at the Watt hour rating indicated next to “Use”.

Example of Use and Shipping Label Marking

USE: 120 Wh Shipping: 3 x 40 Wh
For example, Shipping Wh rating might indicate 3 x 40 Wh, meaning 3 batteries of 40 Watt hours each. The Use Wh rating might indicate 120 Wh (1 battery implied)

Fuel Gauge Battery Packs

Important Safety Instructions for All Battery Packs

WARNING: Read all safety warnings and all instructions for the battery pack, charger and power tool. Failure to follow the warnings and instructions may result in electric shock, fire or serious injury.

• DO NOT attempt to charge the battery pack with any chargers other than the ones in this manual. The charger and battery pack are specifically designed to work together.
• These chargers are not intended for any uses other than charging DEWALT rechargeable batteries. Any other uses may result in risk of fire, electric shock or electrocution.
• Do not expose the charger to rain or snow.
• Pull by the plug rather than the cord when disconnecting the charger. This will reduce the risk of damage to the electric plug and cord.
• Make sure that the cord is located so that it will not be stepped on, tripped over or otherwise subjected to damage or stress.
• Do not use an extension cord unless it is absolutely necessary. Use of improper extension cord could result in risk of fire, electric shock or electrocution.
• When operating a charger outdoors, always provide a dry location and use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
• An extension cord must have adequate wire size (AWG or American Wire Gauge) for safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is, 16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. When using more than one extension to make up the total length, be sure each individual extension contains at least the minimum wire size. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The lower the gauge number, the heavier the cord.

Minimum Gauge for Cord Sets

• Do not place any object on top of the charger or place the charger on a soft surface that might block the ventilation slots and result in excessive internal heat. Place the charger in a position away from any heat source. The charger is ventilated through slots in the top and the bottom of the housing.
• Do not operate the charger with a damaged cord or plug.
• Do not operate the charger if it has received a sharp blow, been dropped or otherwise damaged in any way. Take it to an authorized service center.
• Do not disassemble the charger; take it to an authorized service center when service or repair is required. Incorrect reassembly may result in a risk of electric shock, electrocution or fire.
• Disconnect the charger from the outlet before attempting any cleaning. This will reduce the risk of electric shock. Removing the battery pack will not reduce this risk.
• NEVER attempt to connect two chargers together.
• The charger is designed to operate on standard 120V household electrical power. Do not attempt to use it on any other voltage. This does not apply to the vehicular charger.

WARNING: Shock hazard. Do not allow any liquid to get inside the charger. Electric shock may result.

WARNING: Burn hazard. Do not submerge the battery pack in any liquid or allow any liquid to enter the battery pack. Never attempt to open the battery pack for any reason. If the plastic housing of the battery pack breaks or cracks, return to a service center for recycling.

CAUTION: Burn hazard. To reduce the risk of injury, charge only DEWALT rechargeable battery packs. Other types of batteries may overheat and bust resulting in personal injury and property damage.

NOTICE: Under certain conditions, with the charger plugged into the power supply, the charger can be shorted by foreign material. Foreign materials of a conductive nature, such as, but not limited to, grinding dust, metal chips, steel wool, aluminum foil or any buildup of metallic particles should be kept away from the charger cavities. Always unplug the charger from the power supply when there is no battery pack in the cavity. Unplug the charger before attempting to clean.

Charging a Battery 

1. Plug the charger into an appropriate outlet before inserting battery pack.
2. Insert the battery pack into the charger, making sure the battery pack is fully seated in the charger. The red (charging) light will blink continuously indicating that the charging process has started.
3. The completion of charge will be indicated by the red light remaining ON continuously. The battery pack is fully charged and may be used at this time or left in the charger. To remove the battery pack from the charger, push the battery release button on the battery pack and then slide the battery pack out of the charger.

NOTE: To ensure maximum performance and life of lithium-ion battery packs, charge the battery pack fully before first use.

Charger Operation 

Refer to the indicators below for the charge status of the battery pack.

DCB107, DCB112, DCB113, DCB115, DCB118, DCB132

DCB107, DCB112, DCB113, DCB115, DCB118, DCB132: The red light will continue to blink, but a yellow indicator light will be illuminated during this operation. Once the battery pack has reached an appropriate temperature, the yellow light will turn off and the charger will resume the charging procedure.

The compatible charger(s) will not charge a faulty battery pack. The charger will indicate faulty battery pack by refusing to light.

NOTE: This could also mean a problem with a charger. If the charger indicates a problem, take the charger and battery pack to be tested at an authorized service center.

Hot/Cold Pack Delay 

When the charger detects a battery pack that is too hot or too cold, it automatically starts a Hot/Cold Pack Delay, suspending charging until the battery pack has reached an appropriate temperature. The charger then automatically switches to the pack charging mode. This feature ensures maximum battery pack life.

A cold battery pack will charge at a slower rate than a warm battery pack. The battery pack will charge at that slower rate throughout the entire charging cycle and will not return to maximum charge rate even if the battery pack warms.

The DCB118 charger is equipped with an internal fan designed to cool the battery pack. The fan will turn on automatically when the battery pack needs to be cooled.

Never operate the charger if the fan does not operate properly or if ventilation slots are blocked. Do not permit foreign objects to enter the interior of the charger.

Electronic Protection System 

Li-Ion tools are designed with an Electronic Protection System that will protect the battery pack against overloading, overheating or deep discharge. The tool will automatically turn off if the Electronic Protection System engages. If this occurs, place the lithium-ion battery pack on the charger until it is fully charged.

Wall Mounting 

DCB107, DCB112, DCB113, DCB115, DCB118, DCB132

These chargers are designed to be wall mountable or to sit upright on a table or work surface. If wall mounting, locate the charger within reach of an electrical outlet, and away from a corner or other obstructions which may impede air flow. Use the back of the charger as a template for the location of the mounting screws on the wall. Mount the charger securely using drywall screws (purchased separately) at least 1” (25.4 mm) long, with a screw head diameter of 0.28–0.35” (7–9 mm), screwed into wood to an optimal depth leaving approximately 7/32” (5.5 mm) of the screw exposed. Align the slots on the back of the charger with the exposed screws and fully engage them in the slots.

1. Switch the Power button (1) to ON position to turn the sprayer ON. If the sprayer has not been used recently, you may hear a low, audible sound. This indicates the pump has turned on and is building pressure in the system. NOTE: If the sprayer was used recently, and still has pressure in the system, the pump may not turn on until the shut-off lever (2) is squeezed.
2. Aim the wand in the desired direction of spraying and squeeze the shut-off lever (2).
   
3. For continuous spraying, squeeze the shut-off lever (2) and rotate the lock (3) clockwise to hold the shut-off lever (2) in the depressed position.
4. Unlock by rotating counterclockwise, if needed, and release the shut-off lever (2) to stop spraying.
5. To turn off the sprayer, switch the power button to the OFF position (1).
6. Always remove any chemicals, and clean the sprayer when finished. See the Cleaning and Storage sections of this manual.

CLEANING

WARNING: Always release pressure from the sprayer prior to cleaning. Disassembly of a sprayer that is still pressurized may result in the high-speed ejection of components.

WARNING: RISK OF PERSONAL INJURY DUE TO CHEMICAL EXPOSURE. Use the appropriate Personal Protective Equipment (PPE) as recommended by the chemical manufacturer and/or refer to the chemical Safety Data Sheet (SDS) of the chemical being used. This includes at least goggles, gloves, and protective clothing.

WARNING: RISK OF DAMAGE TO INTERNAL COMPONENTS. Failure to properly rinse out the sprayer may allow chemical residue build-up that can clog or damage the filters, pump, shut-off, wand, and nozzle. Chemical residue build-up can also contaminate subsequent applications. Leaving chemical liquids in the sprayer when not in use can lead to premature sprayer wear. Never store the sprayer with chemicals in any part of the sprayer.

1. Ensure the sprayer is OFF and remove the battery according to the Removing the Battery section.
2. Remove the cap (1) and empty any extra chemical from the tank into a suitable container for later use or dispose according to the chemical manufacturer’s instructions.
3. Use clean water to thoroughly rinse and empty the tank until all chemicals and residues are removed.
4. Add approximately 1 quart (1 liter) of clean water to the tank.
5. Insert the battery according to the Installing the Battery instructions and switch the Power button to ON position (2) to turn the sprayer ON.
6. Flush water through the pump, hose, shut-off, wand, and nozzle for at least 30 seconds to rinse them out. Failure to rinse out these components may allow chemical residue build-up that can clog or damage the components. After heavy use, rinsing the nozzles may not be enough to remove residue. The nozzles may need to be soaked or cleaned with a small brush.
7. Empty out any remaining water from the tank then continue to spray until water no longer comes out of the nozzle. This indicates that most of the water in the system has been removed.
8. Switch the Power button (2) to OFF position to turn the sprayer OFF and then remove the battery.
9. Squeeze the shut-off lever (B) to release any remaining pressure in the hose.
10. Allow the sprayer to dry. This is best done by removing the cap (1) and filter basket (3) and hanging the sprayer upside down to let it drain.
11. Once the sprayer is dried, turn the sprayer upright and reinstall the filter basket (3) and cap (1) to prevent debris from entering the tank.

Battery Pack Cleaning 

Remove dirt and grease from the exterior of the battery using a cloth or soft non-metallic brush. Do not use water or any cleaning solutions.
