Before using charger, read all instructions and cautionary markings on charger, battery pack,
and product using battery pack.
exposed charging contacts inside the charger can be shorted by foreign material. Foreign mate-
rials of a conductive nature such as, but not limited to, steel wool, aluminum foil, or any buildup
of metallic particles should be kept away from charger cavities. Always unplug the charger from
the power supply when there is no battery pack in the cavity. Unplug charger before attempting
to clean.

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.
Pull by plug rather than cord when disconnecting charger. This will reduce risk of dam-
age to electric plug and cord.
Make sure that cord is located so that it will not be stepped on, tripped over, or other-
wise subjected to damage or stress.
Do not use an extension cord unless it is absolutely necessary. Use of improper exten-
sion cord could result in risk of fire, electric shock, or electrocution.
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. When using more than one extension to make
up the total length, be sure each individual extension contains at least the minimum wire size.
Do not place any object on top of charger or place the charger on a soft surface that
might block the ventilation slots and result in excessive internal heat. Place the charg-
er 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 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 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.
The charger is designed to operate on standard 120V household electrical power. (The
DW9116220 is designed for 220V.) Do not attempt to use it on any other voltage. This
does not apply to the vehicular charger.
with voltage from 7.2 up to 18 volts in about one hour. These chargers require no adjustment
and are designed to be as easy as possible to operate. Simply place your battery pack into a
receptacle of a plugged in charger and it will automatically charge the pack.
The DW9216 is designed with a pass through plug to accept other equipment.
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.
When ordering replacement battery packs, be sure to include catalog number and voltage.
Extended Run-Time battery packs deliver more run-time than standard battery packs. Consult
the chart on the last page of this manual for compatibility of chargers and battery packs.
The battery pack is not fully charged out of the carton. Before using the battery pack and
charger, read the safety instructions below. Then follow charging procedures outlined.
Do not incinerate the battery pack even if it is severely damaged or is completely worn
out. The battery pack can explode in a fire.
A small leakage of liquid from the battery pack cells may occur under extreme usage
or temperature conditions. This does not indicate a failure. However, if the outer seal is bro-
ken and this leakage gets on your skin:
a. Wash quickly with soap and water.
b. Neutralize with a mild acid such as lemon juice or vinegar.
c. If battery liquid gets into your eyes, flush them with clean water for a minimum of 10 min-
utes and seek immediate medical attention. (Medical Note: The liquid is 25-35% solution
of potassium hydroxide.)
Do not store or use the tool and battery pack in locations where the temperature may
reach or exceed 105°F (40˚) (such as outside sheds or metal buildings in summer).
battery pack case is cracked or damaged, do not insert into charger. Electric shock or electro-
cution may result. Damaged battery packs should be returned to service center for recycling.
NOTE: Battery storage and carrying caps are provided for use whenever the battery
is out of the tool or charger. Remove cap before placing battery in charger or tool.
can contact exposed battery terminals. For example, do not place battery in
aprons, pockets, tool boxes, product kit boxes, drawers, etc., with loose nails,
screws, keys, etc. without battery cap. Transporting batteries can possibly
cause fires if the battery terminals inadvertently come in contact with conductive materi-
als such as keys, coins, hand tools and the like. The US Department of Transportation
Hazardous Material Regulations (HMR) actually prohibit transporting batteries in commerce or
on airplanes (i.e., packed in suitcases and carry-on luggage) UNLESS they are properly pro-
tected from short circuits. So when transporting individual batteries, make sure that the battery
terminals are protected and well insulated from materials that could contact them and cause a
short circuit.

The automatic Tune-Up™ Mode equalizes or balances the individual cells in the battery pack
allowing it to function at peak capacity. Battery packs should be tuned up weekly or after 10
charge/discharge cycles or whenever the pack no longer delivers the same amount of work. To
use the automatic Tune-Up™, place the battery pack in the charger and leave it for at least 8
hours. The charger will cycle through the following modes.
1. The red light will blink continuously indicating that the 1-hour charge cycle has started.
2. When the 1-hour charge cycle is complete, the light will stay on continuously and will no

Some chargers are designed to detect certain problems that can arise with battery packs.
Problems are indicated by the red light flashing at a fast rate. If this occurs, re-insert battery pack
into the charger. If the problem persists, try a different battery pack to determine if the charger is
OK. If the new pack charges correctly, then the original pack is defective and should be returned
to a service center or other collection site for recycling. If the new battery pack elicits the same
trouble indication as the original, have the charger tested at an authorized service center.
