Important Safety Instructions for All
Battery Packs
When ordering replacement battery packs, be sure to include
catalogue number and voltage.
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
WARNING: 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.
charger is ventilated through slots in the top and the bottom
of the housing.
•
Do not operate charger with damaged cord or plug—
have them replaced immediately.
•
Do not operate charger if it has received a sharp blow,
been dropped, or otherwise damaged in any way. Take it
to an authorised service centre.
• Do not disassemble charger; take it to an authorised
service centre when service or repair is required.
Incorrect
reassembly may result in a risk of electric shock, electrocution
or fire.
• In case of damaged power supply cord, the supply cord must
be replaced immediately by the manufacturer, its service agent
or similar qualified person to prevent any hazard.
• 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
230V household electrical power. Do not attempt to
use it on any other voltage. This does not apply to the
vehicular charger.
Charging a Battery (Fig. B)
1. Plug the charger into an appropriate outlet before inserting
battery pack.
2. Insert the battery pack 5 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 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
4 on the battery pack.
nOTE: To ensure maximum performance and life of lithium‑ion
battery packs, charge the battery pack fully before first use.
