Charging a Battery

(Fig. B)

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

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 repeatedly indicating that the charging process has started.
3. The Stage 1 charging blink indicator represents the charge process that charges the majority of the battery's capacity. Stage 2 charging blink indicator represents the remainder, or top off charge process, for the battery to reach full capacity.
4. The completion of charge for Stage 1 or Stage 2 will be indicated by the stage's light remaining ON continuously. The battery pack is fully charged when both Stage 1 and Stage 2 charging lights remain ON continuously, and it may be removed and used at this time or left in the charger.
   NOTE: To remove the battery pack, some chargers require the battery pack release button to be pressed. Refer to the indicators below for the charge status of the battery pack.
   

* 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 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 authorised service centre.

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
XR 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

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 25.4 mm long with a screw head diameter of 7–9 mm, screwed into wood to an optimal depth leaving approximately 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.

Charger Cleaning Instructions

Shock hazard. Disconnect the charger from the AC outlet before cleaning. Dirt and grease may be removed from the exterior of the charger using a cloth or soft non-metallic brush. DO NOT use water or any cleaning solutions. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.

If medical attention is needed, the battery electrolyte is composed of a mixture of liquid organic carbonates and lithium salts.
• Contents of opened battery cells may cause respiratory irritation. Provide fresh air. If symptoms persists, seek medical attention.

Burn hazard. Battery liquid may be flammable if exposed to spark or flame.

Never attempt to open the battery pack for any reason. If battery pack case is cracked or damaged, DO NOT insert into charger. DO NOT crush, drop or damage battery pack. DO NOT use a battery pack or charger that has received a sharp blow, been dropped, run over or damaged in any way (i.e., pierced with a nail, hit with a hammer, stepped on). Electric shock or electrocution may result. Damaged battery packs should be returned to service centre for recycling.

Fire hazard. DO NOT store or carry the battery pack so that metal objects can contact exposed battery terminals. For example, DO NOT place the battery pack in aprons, pockets, tool boxes, product kit boxes, drawers, etc., with loose nails, screws, keys, etc.

When not in use, place tool on its side on a stable surface where it will not cause a tripping or falling hazard. Some tools with large battery packs will stand upright on the battery pack but may be easily knocked over.

Transportation

Fire hazard. Transporting batteries can possibly cause fire if the battery terminals inadvertently come in contact with conductive materials. When transporting batteries, make sure that the battery terminals are protected and well insulated from materials that could contact them and cause a short circuit.

NOTE: Lithium-ion batteries should not be put in checked baggage.

DeWALT batteries comply with all applicable shipping regulations as prescribed by industry and legal standards which include UN Recommendations on the Transport of Dangerous Goods; International Air Transport Association (IATA) Dangerous Goods Regulations, International Maritime Dangerous Goods (IMDG) Regulations, and the European Agreement Concerning The International Carriage of Dangerous Goods by Road (ADR). Lithium-ion cells and batteries have been tested to section 38.3 of the UN Recommendations on the Transport of Dangerous Goods Manual of Tests and Criteria.

In most instances, shipping a DeWALT battery pack will be excepted from being classified as a fully regulated Class 9 Hazardous Material. In general, only shipments containing a lithium-ion battery with an energy rating greater than 100 Watt Hours (Wh) will require being shipped as fully regulated Class 9. All lithium-ion batteries have the Watt Hour rating marked on the pack. Furthermore, due to regulation complexities, DeWALT does not recommend air shipping lithium-ion battery packs alone regardless of Watt Hour rating. Shipments of tools with batteries (combo kits) can be air shipped as excepted if the Watt Hour rating of the battery pack is no greater than 100 Whr. Regardless of whether a shipment is considered excepted or fully regulated, it is the shipper's responsibility to consult the latest regulations for packaging, labeling/marking and documentation requirements.

The information provided in this section of the manual is provided in good faith and believed to be accurate at the time the document was created. However, no warranty, expressed or implied, is given. It is the buyer's responsibility to ensure that its activities comply with the applicable regulations.

Transporting the FLEXVOLT™ Battery
The DeWALT FLEXVOLT® battery has two modes: Use and Transport.

Use Mode: When the FLEXVOLT^TM battery stands alone or is in a DeWALT 18V product, it will operate as an 18V battery. When the FLEXVOLT^TM battery is in a 54V or a 108V (two 54V batteries) product, it will operate as a 54V battery.

Transport Mode: When the cap is attached to the FLEXVOLT^TM battery, the battery is in Transport mode. Keep the cap for shipping.

When in Transport mode, strings of cells are electrically disconnected within the pack resulting in 3 batteries with a lower Watt hour (Wh) rating as compared to 1 battery with a higher Watt hour rating. This increased quantity of 3 batteries with the lower Watt hour rating can exempt the pack from certain shipping regulations that are imposed upon the higher Watt hour batteries.

For example, the Transport Wh rating might indicate 3 x 36 Wh, meaning 3 batteries of 36 Wh each. The Use Wh rating might indicate 108 Wh (1 battery implied).

Storage Recommendations

1. The best storage place is one that is cool and dry away from direct sunlight and excess heat or cold. For optimum battery performance and life, store battery packs at room temperature when not in use.
2. For long storage, it is recommended to store a fully charged battery pack in a cool, dry place out of the charger for optimal results.

NOTE: Battery packs should not be stored completely depleted of charge. The battery pack will need to be recharged before use.

6. Squeeze the trigger switch . The expander head will begin to expand, retract, and rotate slightly.

NOTE: Hold the ring and tubing so they DO NOT rotate with the head.

PEX spec	Recommended Number of Expansions	Recommended Accessory
Ø16x1.8 mm	4-5	DCE40016
Ø16x2.0 mm	5-6	DCE40016
Ø16x2.2 mm	6-7	DCE40016
Ø20x1.9 mm	6-7	DCE40020
Ø20x2.0 mm	7-8	DCE40020

DO NOT expand more times than necessary.

NOTE: The number of expansions needed may vary depending on temperature or user technique. To avoid over-expanding the PEX tubing, DO NOT keep tool in the expanded position with PEX tubing in place.

7. After achieving the recommended number of expansions, remove the tubing when the expander cone segments are retracted and release the trigger switch . DO NOT expand the PEX tubing beyond the tool's capacity of 32 mm (up to 2.9 mm wall thickness).
8. Wipe off the excess grease from inside the PEX tubing.
9. Slide the PEX tubing over the fitting until it is flush with the fitting shoulder. The connection may be tight. If you are unable to slide the PEX tubing over the fitting, remove the fitting from the PEX tubing and re-expand until you can secure a proper fit.

NOTE: The PEX tubing should fit tightly against the fitting shoulder. If there is more than a 1.6 mm gap between the PEX tubing and the shoulder, cut 50 mm off the end of the PEX tubing and restart procedure with a new PEX ring.

Cold Weather Use
Use of your PEX expander in colder temperatures (4°C) requires a longer contraction time and less expansions. Attempting to make PEX connections in extreme temperatures (-15°C) is not recommended.

Expansion Markings

(Fig. G)

Incorrect expansion of the PEX tubing can create deep grooves in the material which could result in faulty connections and risk of property damage.

Examples of correct and incorrect markings on the inside of the PEX tubing are shown in Fig. G. Incorrect markings could indicate the head is not rotating properly, or the tubing is rotating with the head.
